carbon cycle in the Mediterranean biome

Answers

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 ______

Answers

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).

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

Answers

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.

How does the final number of chromosomes in each cell compared to the starting number of
chromosomes in both cells?

Answers

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.

Why are bones hard and elastic at the same time? Explain your answer.
Give examples how bones protect our inner organs.

Answers

Explanation:

Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight.

Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.

Bones are made up of a framework of a protein called , with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it's needed by other parts of the body. The amounts of certain vitamins and minerals that you eat, especially vitamin D and calcium, directly affect how much calcium is stored in the bones.

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.
