Stopping is the blocks of rocks falling into magma. Convergent plate boundaries are the places where tectonic plates smash together. Injection is when the magma is forced into the fractures.
What are the Convergent plate boundaries?A convergent plate boundary results when the tectonic plates converge, the one with thin oceanic crust subducts beneath the one which are capped by the thick continental crust. A subduction zone generally consists of the material that are scraped off the ocean floor near the coast and a chain of volcanoes farther inland.
Stopping is the blocks of rocks falling into magma. Convergent plate boundaries are the places where tectonic plates smash together. Injection is when the magma is forced into the fractures. A magma chamber is a cavity where magma resides. A divergent plate boundary is where the tectonic plates pull apart.

What is one trait that could be used to separate these albatrosses into two groups of two birds each
Answer: Large group of solid black feathers vs. Black and gray patterned feathers
Explanation:
QUESTION IS INCOMPLETE. It shows 4 different groups of animals:
Short-tailed albatrossShy albatrossWandering albatrossLaysan albatrossAlbatrosses are among the largest flying birds, forming a family of large seabirds distributed throughout most of the Antarctic, Pacific and South Atlantic oceans. They have the largest wingspans which allows them to move very efficiently in the air with little effort. They feed on squid, fish and krill, either by picking up dead animals or by capturing their live food at the surface of the water or by diving.
To answer this, we can use the dichotomous key which is a tool that allows the identification of organisms. There are keys to determine animals, plants, fungi, bacteria, protista, protozoa or any other living being; keys that reach the level of species, genus, family or any other taxonomic category. A dichotomous key is based on definitions of morphological, macroscopic or microscopic characters, from which two possible solutions are derived, depending on whether or not they have a certain character, repeating the process of defining characteristics, until the organism in question is reached.
In this example, we should look at the colors and patterns on their plumage and beaks. With that information, we can separate these albatrosses into:
Large group of solid black feathers vs. Black and gray patterned feathers.
Answer:
The one trait is the wing color. One group can be separated into solid black wings and the other group can be separated into black/white wings.

Identify the way that leptin produced by fat cells of adipose tissue in the abdomen can send a signal to the neuroendocrine cells in the hypothalamus
Answer:
Leptin is a protein hormone composed of 167 amino acids of the cytosine family, it is synthesized mainly by white adipose tissue. The leptin receptor is related to that of receptors for cytosines (since it uses Janus or JAK type kinases and STAT-3 proteins as intracellular mediators of transcription pathway), it is predominantly found in the hypothalamus (particularly in the arcuate nucleus and to a lesser extent in the nuclei dorsomedial and ventromedial), hippocampus and cerebellum. There is evidence that leptin acts at the level of the arcuate nucleus, preventing the formation of NPY.
Explanation:
Leptin is produced exclusively in adipose tissue cells in a wide variety of species, including humans, and its concentration is higher in overweight than in lean individuals. The biological actions of leptin can be classified into two groups, those that are exerted in the tissues of the central nervous system, mainly the hypothalamus, and those that are carried out on the peripheral tissues. The former regulate body weight downward, decrease food intake, increase basal energy expenditure and modify some neuroendocrine functions such as reproduction, while the latter have effects on proliferation, differentiation and metabolism of peripheral tissues. The leptin that reaches the hypothalamus, in addition, inhibits protein synthesis and the secretion of neurons producing NPY / AgRP of the arcuate nucleus and stimulates the synthesis and secretion of those containing POMC. NPY (neuropeptide Y) is produced in the hypothalamic arcuate nucleus. This neurotransmitter arrives through the projections of the neurons of said nucleus to the paraventricular nucleus, which is the area where it is released. There are several studies that have shown that an increase in NPY leads to an increase in the sensation of hunger and thus to hyperphagia and obesity. Leptin acts at the level of the arcuate nucleus, preventing the formation of NPY. The leptin receptor lacks enzymatic activity in its intracellular domain. Instead, it is linked to members of the janus kinase family, which belong to a class of tyrosine kinases. The binding of the ligand activates the Jak kinase and leads to the phosphorylation of certain cytoplasmic proteins. Within these proteins there is a class of cytoplasmic transcription factors called signal transducers and activators of transcription (STAT).
A protein hormone synthesized majorly by white adipose tissue is leptin. It is secreted from the fat cells or adipose tissue of the body and concerns fat and obesity.
The obese individual has a high amount of leptin compared to a lean person.
The leptin works on tissues of the CNS mainly the hypothalamus and PNS. Leptin binds to members of the Janus kinase family of the tyrosine kinases class.
The ligand-binding triggers the Jak kinase and results in the phosphorylation of specific cytoplasmic proteins that includes the class of cytoplasmic transcription factors named signal transducers and activators of transcription (STAT).
CNS controls body weight, reduce food intake, improve basal energy expenditure and modify some neuroendocrine processes like reproduction.
PNS affects the expansion, metabolism and differentiation of peripheral tissues.
The leptin that moves towards the hypothalamus impedes protein synthesis and the secretion of neurons producing NPY / AgRP.
NPY (neuropeptide Y) is formed in the hypothalamus and arrives through the outgrowths of the neurons of the arcuate nucleus. It moves towards the para-ventricular nucleus from where it is released.

Why is it important for Earth’s magnetic field that the inner core is hotter than the outer core?
The inner core provides the heat source for outer core convection.
The inner core’s heat produces the Coriolis effect needed for rotation.
The inner core’s heat allows the outer core to conduct electricity.
The inner core provides the energy for Earth’s orbit around the Sun.
Answer: The inner core provides the heat source for outer core convection.
Explanation: The fact that the inner core is hotter than the other core allows for the bottom of the outer core to be heated. As this happens, it expands and rises up to the top of the layer. As it rises, it cools and sinks back down to the bottom, just to be warmed again.
Assume that the unaided human eye has a limit of resolution of about 0.25 mm. What was the limit of resolution of Hooke's microscope
Answer and Explanation:
The Hooke microscope was designed by the famous British scientist in the 1600s. Robert Hooke only design the microscope; actually, the microscope was made by instrument maker.
Robert Hooke's design improved microscope illumination and mechanism, which enhance the magnification to 50X and improved resolution.
Robert Hooke was the first man who coins the name cell after observing angular spaces that saw in a thin cork section. He used a compound microscope to observe the pores in the cork.The Hooke microscope and telescope have some common features, such as a socket and ball joint for disposing of the body, separate draw tubes and an eyecup to retain the correct distance between eyepiece and eye. The microscope body tube was made of wood. Hooke used a bi-convex objective lens, tube lens and two additional lenses. The resolution limit of the microscope depends on how well a lens focus light. We do not know we have exact information about the resolution of the Hooke microscope. However, by using the magnification power of the instrument, we can estimate the resolution limit. Hooke microscope has 30X magnification power.
The limit of resolution of Hooke's microscope was 8.3 μm.
The Hooke's microscope was developed by the scientist Robert Hooke in the late 1600s in order to observe cellular structures.Hooke's microscope consisted of a bi-convex objective lens and two additional lenses.The resolution of Hooke's microscope was 8.3 micrometers (μm), where 1 μm is equal to 1×10−⁶ m.In conclusion, the limit of resolution of Hooke's microscope was 8.3 μm.

if a less concentrated initial solution of sodium bicarbonate was used in beaker C would that solution require more or less bicarbonate to neurolize the acid
Answer:
It depends on the concentration of acid in the solution.
Explanation:
If the acid present in the solution is in concentrated form then the salt i. e. sodium bicarbonate is also used in concentrated form in order to neutralize the acidic solution while on the other hand, if a solution is less acidic then less concentrated amount of sodium carbonate is used to neutralize the acid solution so the concentration of sodium bicarbonate is used according to the concentrated of acid in the solution.
carbon cycle in the Mediterranean biome
Explanation:
The northwestern Mediterranean Sea (NWMS) is biologically one of the most productive Mediterranean regions. NWMS pelagic planktonic ecosystem is strongly influenced by hydrodynamics, in particular by deep convection that could significantly weaken under the influence of climate change. Here we investigate the response of this ecosystem and associated carbon cycle to the long‐term evolution of oceanic and atmospheric circulations. For that we developed a tridimensional coupled physical‐biogeochemical model and performed two groups of annual simulations under the climate conditions of respectively the 20th and the end of 21st centuries. Our results suggest that the evolution of oceanic and atmospheric circulations does not modify the NWMS pelagic planktonic ecosystem and associated carbon cycle at a first order. However, differences mainly induced by the deep convection weakening and the surface warming are obtained at a second order. The spring bloom occurs 1 month earlier. Resulting from the decrease in nutrients availability, the bottom up control of phytoplankton development and bacteria growth by the nitrogen and phosphorus availability strengthens and the microbial loop intensifies as the small‐sized plankton biomass increases. Carbon net fixation and deep export do not change significantly. The choice of the biogeochemical initial and boundary conditions does not change the representation of the ecosystem seasonal cycle, but the associated uncertainty range can be one order of magnitude larger than the predicted interannual and long‐term variabilities. The uncertainty range of long‐term trends associated with the physical forcing (hydrological, atmospheric, hydrodynamical, and socioeconomic) is much smaller (<10%).

An organism will have both genotype and a phenotype for a specific trait. If we are considering what trait
is physically expressed, this is ______
If we consider the genetic basis of
the trait, this is ______
Answer:
If we are considering what trait is physically expressed, this is the phenotype. If we consider the genetic basis of the trait, this is the genotype.
Explanation:
An individual's genotype is the collection of its genes. When we talk about individual traits, the term genotype refers to the combination of alleles that determine it. For example, our eye color will depend on our genotype.
An individual's phenotype includes its observable characteristics. It's mostly influenced by the individual's genotype, but there are other factors that influence it as well - epigenetic changes and environmental factors. For example, flamingos aren't naturally pink. They are naturally white but turn pink because of the pigments found in the organisms they feed on. Their genotype dictates the white color, but because of environmental factors, they are pink (their phenotype).

The graphs show the age structure for each of three countries. The horizontal bars show the percentages of the population in each age group, by gender. Note that for Country 1, about 20 percent of the population is between the ages of 0 and 4. This is the greatest percentage of any 4-year age span in all three countries.
Country 1 has an age structure in which ages 0-4 represent 20% of the population, and older age groups have decreasing percentages. Country 2 has age groups that are all about the same. Country 3 skews to older age groups.
Which conclusion about Country 1 does its age structure support?
A. Young children have a lower death rate in Country 1 than in the other countries.
B. Young children have a higher death rate in Country 1 than in the other countries.
C. More young children live in Country 1 than in the other countries.
D. Fewer young children live in Country 1 than in the other countries.
Answer:
C. More young children live in Country 1 than in the other countries.
Explanation:
The described graph shows that more young children live in Country 1 than in the other countries. This is clearly stated in the first paragraph: This is the greatest percentage of any 4-year age span in all three countries. This automatically means that options B and D are incorrect.
Option A is the second-best one. However, the fact that there are more young children in Country 1 doesn't necessarily mean that their death rate is lower. It could be, but correlation doesn't equal causation. There are more young children probably because the younger population is more present in that country and more children are born.
This is why option C is the correct one.
How does the final number of chromosomes in each cell compared to the starting number of
chromosomes in both cells?
Answer:
Double
Explanation:
Each haploid cell contributes half the chromosomes
Cell division is the process in which the genetic material and cytoplasm are divided to produce the daughter cells. The cell division can be mitotic or meiotic.
The division of chromosomes can be distinguished into:
Mitosis is the process of cell division in which the number of chromosomes in the parent cell is similar to the daughter cells. The mitotic division occurs in the somatic cells of an organism. The meiotic division is the process in which the number of chromosomes in the parent cells is halved. The meiotic division occurs in the reproductive cells of the sexually reproducing organisms.
Thus, the final number of chromosomes will be 46 in the mitotic division, whereas, in the meiosis, it will be half the parental chromosomes.

what would most likely result if the four stages of mitosis were not followed by cytokinesis?
Answer:
Explanation:
If cytokinesis did not occur, the cell cytoplasm will not be able to undergo division or divide. As a result, there won't be division of two daughter cells that are identical to the parent. Therefore, it will remain at rest and there won't be separation or division of the parent cell. The cell will still remain as it was. Therefore, there won't be cell division.

A. Is the formula balanced as written? Why or why not?
Answer:
This question is asking to complete and balance the equation as follows:
C6H1206 + 602 → 6CO2 + 6H2O
Explanation:
The equation described in this question is that of cellular respiration, which is the process whereby glucose is broken down to release energy (ATP) needed by the cell.
- The inputs of this equation are glucose (C6H1206) and oxygen (O2).
- The outputs of the equation are carbon dioxide (CO2) and water (H20).
According to this question, to balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hydrogen atoms on each side of the arrow as follows:
C6H1206 + 602 → 6CO2 + 6H2O
Note: the equation is not balanced as it is written in the question.
