Another hypothesis suggested by researchers that can be used to further study the role of predators in the natural selection process is the study of the total or partial absence of predators, visualizing the response in the environment.
What is the role of predators?Predators can act by controlling the population size of some species. When the population size of their prey begins to decrease, many species seek to feed on prey that are in greater abundance in the environment.
With this information, we can conclude that another hypothesis suggested by researchers that can be used to further study the role of predators in the natural selection process is the study of the total or partial absence of predators, visualizing the response in the environment.

If a client has a headache what should the trainer do
When you do have a headache, avoid jarring, high-impact exercise like running or kickboxing because it's likely to aggravate the pain. Intense exercise will also cause you to sweat, leading to dehydration, which can worsen a headache as well, Ramadan says.
Fish breathe underwater through gills that remove dissolved oxygen from the water. What phenomenon allows oxygen to dissolve in water
Answer:
The correct answer is "aeration".
Explanation:
Fish depend on the presence of dissolved oxygen in the water to breathe, because they take oxygen from water in a mechanism known as countercurrent exchange. Oxygen gets dissolved in water when winds stirs it in a phenomenon known as aeration. Aeration brings water and oxygen in direct contact, and not only is responsible of producing dissolved oxygen in water, but also increases its palpability by removing its flat taste.

Which of the following is not a true statement regarding the genetic code?
A. The genetic code is nearly universal, with only a few minor exceptions.
B. The genetic code is nonoverlapping.
C. The genetic code is degenerate.
D. The genetic code is triplet-based.
E. Each codon represents a different amino acid.
Answer:
E. Each codon represents a different amino acid.
Explanation:
The genetic code refers to the set of rules guiding the translation of nucleotide bases in DNA or RNA into an amino acid sequence (proteins). The genetic code contains all the codons in the genome, which is a group of three nucleotide base (triplet-based). Each codon species a particular amino acid, however, more than one codon can code for a particular amino acid. This characteristics of the genetic code is called DEGENERACY.
The genetic code is said to be nearly universal because the same codon encodes the same amino acid in almost all living organisms with only few exceptions. The nonoverlapping nature of the genetic code refers to the fact the three bases of a codon are read independently from the bases of another codon i.e. codons do not overlap.
A codon represents one amino acid but more than one codon can represent the same amino acid. Hence, option E is untrue

For translation to take place, which of the following would not be required to be present?
1. DNA.
2. mRNA.
3. tRNA-amino acid complex.
4. rRNA.
Answer:
The correct answer is 1. DNA would not be required to be present.
Explanation:
Translation takes place in ribosomes, in a very similar way in prokaryotes and eukaryotes, starting with a start codon and ending with a stop codon. The messenger RNA is the one that carries the information for protein synthesis, that is, it determines the order in which the amino acids will be joined. Ribosomes are made up of two functional subunits of different sizes that associate or dissociate throughout the biosynthetic process. In addition to ribosomes, a series of protein translation factors also participate in the process, interacting with aminoacyl-tRNA molecules, ribosomes and mRNA to carry out the translation process with precision. The amino acids are transported by the transfer RNA, specific for each one of them, and are taken to the messenger RNA, where the codon of the latter and the anticodon of the transfer RNA are paired, by complementarity of bases, and in this way they are they place themselves in the position that corresponds to them. Once the synthesis of a protein is finished, the messenger RNA is free and can be read again.

What is a tumor? (1 point) o a mass of cells a stage in the cell cycle O a checkpoint in the cell cycle 0 a cell that results from mitosis
Answer:
A mass of cells
Explanation:
A tumor is a mass of cells from cancerous growth.
A mass of cells is formed by abnormal tissue growth in an organism as a result from cancer, where cells grow uncontrollably and ignore signals from the body to stop producing cells.
A tumor is characterized as the mass of the cell. Thus, the correct option for this question is A.
What are the different types of tumors?There are two different types of tumors are there. They are as follows:
Benign tumors: It is a non-cancerous tumor that does not show metastasis and is non-invasive. It stops the growth after reaching a certain size. This type of tumor is less fatal to the body. Malignant tumors: It is a cancerous tumor that significantly shows metastasis and thus invades other body parts. This type of tumor shows indefinite growth and is more fatal to the body.Due to the process of repeated cell division, cells form a large mass of tissue called tumors. This is also characterized due to uncontrolled rapid division and proliferation of cells, and the formation of tumor occurs.
Therefore, a tumor is characterized as the mass of the cell. Thus, the correct option for this question is A.

If a mutation in DNA caused a new amino acid sequence to occur, what might happen to the subsequent protein?
The amino acids contain R groups that interact with each other creating a three - dimensional structure. This higher - order structure decides the biological activity of that protein. if the wrong amino acid joins the polypeptide chain the higher - order structure will change, effecting the functioning of the protein.This will lead to many diseases such as sickle cell anemia is most common.

1. Give two other names for AB.
2. Name three points that are collinear.
3. Give another name for plane F.
4. Name a point that is not coplanar with A, B, and C.
5. Give another name for CD.
6. Name three rays with endpoint B.
7. Name a pair of opposite rays.
8. Give another name for CD.
Problem 1
Two other names for line AB are
Line BALine hThe order of the letters doesn't matter which is why AB is the same as BA. Line h is another name since the h is attached to the line.
======================================
Problem 2
Three points that are collinear are: C, B, and D
Those three points all fall along the same vertical line (line g)
=====================================
Problem 3
Pick any three points you want in plane F as long as those points do not fall on the same line. The only three points we can pick are A, B and E. Those points are not all on the same line. They uniquely define plane F. So we can say "plane ABE" in place of "plane F". In this case, the order of the lettering does not matter.
======================================
Problem 4
Point E is not coplanar with A, B and C. Plane ABC is a vertical wall (of sorts) while point E is on the floor (plane F) away from the wall ABC. In contrast, a point like D is on plane ABC because line g goes through this plane as well.
=======================================
Problem 5
Line CD can be written as
line CBline BCline DCline BDany of those are valid. All we need are two points that are on line CD. The order doesn't matter.
=======================================
Problem 6
Start with point B. Then add on a letter that forms a ray or half a line. We could write
ray BCray BAray BDWe cannot write ray BE since there is no line connecting the two points. Also, when it comes to naming rays, the order does matter. The first point is where we start and the second point is where the ray aims and goes on forever toward. Something like ray BC is not the same as ray CB (since the endpoint here is C instead of B).
=======================================
Problem 7
One pair of opposite rays is BC and BD. They point in completely different directions and both fall on along the same straight line extended out infinitely in both directions. Put another way: gluing together the endpoints of opposite rays forms a line.
=======================================
Problem 8
This seems to be a repeat of problem 5. I'm not sure if this is a typo or not.
In _____________ selection, individuals with both extreme forms of a trait are at a selective advantage.
Answer:
disruptive/diversifying selection
Explanation:
Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.
Transport proteins play a role in both?
Answer:
Transport proteins play a role in both active and passive transport to move molecules across the plasma membrane
Transport proteins play a role in both passive and active transport. Therefore, option A is correct.
Cell transport means the transportation of a molecule or substance across a plasma membrane. The molecule has the ability to enter or exit the cell. The plasma membrane and cell membrane are both permeable to different substances like ions and water molecule.
Active Transport is the movement of molecules from lower concentration to a region of higher concentration against a gradient with the use of energy.
Passive transport is the movement of ions and other molecular substances across membrane along the concentration gradient, without any need of energy.
Exocytosis, endocytosis (movement of molecule in and out of cell) and vesicle transport(transport of vesicles inside of cell) do not require transport protein.
Phagocytosis is a type of endocytosis that is involved in engulfment of substance or damaged cell.
Therefore, option A is correct.

Answer:
The dark peppered moth's population increased as the use of coal increased because, since the trees were darker, it was harder for predators to see them. The light moths were easily seen and, therefore, much easier to get eaten/killed which is why their population went down.
1. The variation is the color of the moth (light vs dark).
The selection is directional selection (the trait is favorable, so it will become common among the population).
2. The peppered moth population would most likely decrease dramatically. Majority of the 95% of dark moths would get killed off since the trees are becoming light again. The light moths would be at 5% and slowly increase as the trees became lighter. Therefore the population would decrease.
3. The variation is the color of the beetle (green vs brown).
4. The brown beetle is selected for because their color is allowing them to not get eaten.
The green beetle population will decrease until there are no more.
The brown beetle population will increase until they are the only color.
