Answer:
Part A-One of the variations have eyes as well as some pigmentation on them. They live near the surface of the water. The other variation does not have eyes and are often albinos. I found that these fish live in deep, dark caves.
Part B-Yes. I think that these fish are an example of natural selection. The blind fish live in caves and eyes take up energy that could be used somewhere else in the fish. So, they developed into fish with no eyes, allowing them to function more efficiently.
Part C- As a species, they have genetic diversity because the two populations have separate genes. The two fish types developed different traits because of their separate habitats.

100 POINTS IF YOU ANSWER ASAP!!!!!! [About 2 or more sentences for each box]
Answer:
I don't understand the question that well but from what I understand I have to say how they relate or effect each other.
Mass. Mass can be effected by your weight and height. Your weight can help increase mass but size matters to. Think of gold. Gold is very dense so it's mass is greater. when you pick up an equal size of gold and another object gold will feel heavier because of its size and weight.
Weight. think of gold as well. Because of its mass it feels heavier. Weight can also mean it is larger. Think of a pebble and a boulder. They are both stone so we can compare them. A boulder is larger and it is heavier.
volume. volume is basically size. if something's mass is high it will be large if it is not dense. just was before size can be directly related to weight if they are the same substance.

b. ft x ff
c. ft * ft
d. FF * FF
Answer:
a
Explanation:
ff x ff is the cross that will produce only offspring with smooth leaves.
What is cross?Cross means breeding of parents to produce offspring.
What is produce?Produce means to generate.
What is offspring?Offspring is the product of a cross.
f is the recessive allele of smooth leaves whereas F is the dominant allele of fuzzy leaves.
So the cross ff will give all smooth leaves where as FF will give all fuzzy leaves.

Fungi tend to reproduce sexually when nutrients are limited or other conditions are unfavorable,but they reproduce asexually in more ideal conditions. Why is this strategy successful?The fungal colonies reproduce by the process of asexual reproduction during the availability ofnutrients. When favorable conditions are present the fungi are succeed, therefore fungi do notchange its growth features. When conditions are unfavorable the fungi undergo sexualreproduction process. Sexual reproduction produces offspring which are distinct from the parent.This strategy is successful because this reproduction increases genetic variation, which entailsthe odds of some progeny, which are suited to new and challenging conditions. When nutrientsare available in plenty the mother cell do not depend on the other cells, rather multiply by mitosisgiving rise to daughter cells but during unfordable conditions
Answer:
Sexual reproduction produces offspring which are distinct from the parent.This strategy is successful because this reproduction increases genetic variation, which entailsthe odds of some progeny, which are suited to new and challenging conditions.
Explanation:
Sexual reproduction produces genetic variability, as two nucleic unites to produce a new offspring this allows the fungus to adapt to new environments. Sexual reproduction in the fungi consists of three sequential stages plasmogamy, karyogamy, and meiosis.
It involves diploid chromosomes pulled into two daughter cells, each containing an haploid set of chromosome.
Plasmogamy is the fusion of two protoplasts which brings together two compatible haploid nuclei this nuclear types are present in the same cell, but are not yet fused. Karyogamy then leads to the fusion of the haploid nuclei and the formation of a diploid nucleus. The new cell formed by karyogamy is the zygote.

is studying?
gravitational potential energy
electrical energy
chemical energy
elastic potential energy
PLEASE REPLY SOON AS POSSIBLE !!
Answer:
gravitational potential energy
Explanation:
Gravitational potential energy is that energy that an object possesses due to its height or vertical position. The vertical position of the object causes it to be attracted to the Earth's gravitational field, which is the basis in the name. In this case, a ball is said to roll down a ramp, which is an inclined surface.
Johanna can be said to be studying the GRAVITATIONAL POTENTIAL ENERGY because of the falling or vertical position of the ball from the ramp in response to the Earth's gravity.

7. In what other places, besides central Africa, can people with a high eumelanin content be found
living today?
Answer:
Although people living in low latitudes have high levels of eumelanin, this pigment can be found in people around the world (because it is predominant in people with brunette hair)
Explanation:
In animals and humans, melanin pigments play key roles in eye, hair, and skin coloration. Basically, there are three main types of melanin pigments: eumelanin (brown-black and insoluble), pheomelanin (yellow-red and soluble in alkali solution) and neuromelanin (found in some parts of the brain). Eumelanin is predominant in black people and brunette hair people, this being consequently found around the world. There are two distinct classes of eumelanin: black eumelanin and brown eumelanin, which differ in their patterns of polymeric bonds, and they have an incidence on the type of coloration (e.g., black eumelanin is found in people with grey hair).

In the carbon cycle, how is carbon stored in organisms and then exchanged with the environment?
Answer:
Photosynthesis, Decomposition, Respiration and Combustion.
Explanation:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
Students in a science class were asked to investigate how missing or damaged organelles affect cellular homeostasis for cells found in muscle tissues. Which of the following questions should they ask to determine if these muscle cells are functioning properly? A. At what rate does the cell wall need to break down its carbohydrate structure to meet the high energy needs of the cell? B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? C. At what rate do the ribosomes of the cell need to work to produce enough glucose to meet the high energy needs of the cell? D. At what rate do the chloroplasts of the cell need to capture enough sunlight to meet the high energy needs of the cell?
Answer:
B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?
Explanation:
Asking scientific questions is the bedrock of scientific investigations. In this case, investigation on how missing or damaged organelles affect cellular homeostasis for cells found in muscle tissues is being carried out. Hence, an appropriate question will be that which suits organelles found in muscle cells.
Mitochondrion is an organelle responsible for the synthesis of usable energy in form of ATP in eukaryotic living cells like animal muscle cells. It is therefore an organelle found in muscle cells. An appropriate question will, therefore, be: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?
Note that other options are wrong because, cell wall and chloroplast are not found in muscle cells, while ribosomes are not organelles for production of glucose.
The scientist eventually observes the cells undergo a sudden and radical shift in their structure/shape and their motility (ability to move). He asks himself questions about what is causing this shift in behaviors and begins to design an experiment to determine the answer. Briefly describe how the scientist practiced both the exploration and testing aspects of scientific inquiry
Answer:
The scientist raises a question about cellular phenomena that is tested by a hypothesis-led procedure, and the resulting information may then be used to find the reasons for his observations
Explanation:
The scientific method is a rigorous process that involves a series of steps: 1-to make observations about the real world, 2-to ask a question related to these specific observations, 3-to raise a working hypothesis, 4- to test the hypothesis, 5-to analyze the results and 6-to obtain conclusions (i.e., reject or confirm the hypothesis). In the scientific method, a scientific question must be measurable, defined and testable. Moreover, the scientific hypothesis must be a well-defined and coherent conjecture which is tested by experimental or observational procedures in order to seek answers to the scientific question.

Which of the following experimental treatments would NOT be a potentially effective strategy to inhibit or prevent cell-cell adhesion? Which of the following experimental treatments would NOT be a potentially effective strategy to inhibit or prevent cell-cell adhesion? removal of calcium ions from the extracellular space application of a protease that specifically destroys CAMs application of an antibody that inhibits the function of lectins adding an antagonist to prevent integrin function
Answer:
adding an antagonist to prevent integrin function
Explanation:
An antagonist is a drug capable of binding to a specific receptor, thus blocking the binding of endogenous ligand molecules. According to their mode of functioning, the antagonists are classified into four classes: chemical, physiological, competitive and non-competitive. Integrins are specific transmembrane receptors that facilitate cell adhesion. In consequence, in the case above indicated, the use of an antagonist for the integrin receptor will prevent cell adhesion.
