The newts have become more poisonous over time, as a result, leading to a kind of evolutionary arms race. This is an example of coevolution.

Coevolution is the process of evolutionary change that occurs between pairs or group of species as they interact with one another.

The predator-prey relationship is the most common type of coevolution. This involves the prey evolving so as to avoid capture and thus leading to the evolution of the predator so as to become more effective hunters.

Predator-prey coevolution is a kind of evolutionary arms race.

A student is looking through a microscope at some cells of an onion root tip. Many of these cells are undergoing division since the root tip grows quickly and requires more cells. Which cell is going from metaphase into anaphase? W X Y Z

It's y

The cell Y is transitioning from metaphase to anaphase.

The chromosomes are at their second-most compacted and coiled state during the mitotic stage of the eukaryotic cell cycle, known as metaphase. These chromosomes, which contain genetic material, align in the cell's equator before being divided into the two daughter cells.

A phase of cell division known as "metaphase" (mitosis or meiosis). Individual chromosomes are typically dispersed throughout the cell nucleus. During metaphase, the cell's nucleus disintegrates and the chromosomes condense and migrate toward one another, aligning in the middle of the dividing cell.

The duplicate genetic material existing in a parent cell's nucleus is divided into two identical daughter cells during the third stage of mitosis, known as metaphase.

Buffers are chemicals that help a liquid resist changing its acidic properties when other chemicals are added that will normally cause a change in these properties.

Answer:

buffers are chemicals that help a liquid resist changing its acidic properties. the reason they are important to cells is because buffers maintain the right pH of a liquid.

According to Plato, the souls of people tend to reincarnation, that is, the souls of each person have had previous lives in which they have developed and have had different experiences.

Thus, as a way to generate an impartiality of the soul, which allows it to start a new life without influences on previous lives, they should drink water from the River of Forgetfulness.

This made the souls unable to remember anything from their previous lives or the adrenal world in which they were before coming back to life.

Collagen has: A. pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable).

Collagen can be defined as the main or most abundant structural protein found in the bones, tendons, connective tissues, skin and muscles of a living organism such as a human being.

Basically, collagen is a chemical substance (protein) made up of amino-acids and it holds the human body together.

Hence, collagen typically makes up about 30% of the proteins contained within the human body.

Additionally, collagen comprises the following specific amino-acids:

Each of the three chains of a collagen triple helix with 3.3 residues per turn, is normally stabilized by the steric repulsion between the pyrrolidine rings of hydroxyproline, glycine and proline residues.

Therefore, the pyrrolidine rings of collagen helps in the stabilization of helices and glycine residues, at every third position because the only residue that fits inside of the super-helical cable is the glycine residues.

When two species compete with one another for the same resource, their niches overlap. Resource partitioning reduces the number of species that can share a given resource. Some bats prey on certain moths, hunting them using echolocation. i.e. bats, have evolved to change the frequency they use for echolocation.

Answer:

I would go with the sequence of the bases in the nucleic acid chain

The sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.

Deoxyribonucleic acid is a polymer which is made up of two polynucleotide chains that coil around each other to carry the genetic instructions for growth, function, development, and reproduction in all known organisms and many viruses. DNA and RNA are nucleic acids.

DNA is made up of chemical building blocks called nucleotides which are building blocks made up of three parts:

1. A phosphate group

2. A sugar group

3. One of four types of nitrogenous bases i.e. adenine (A), cytosine (C), guanine (G), and thymine (T)

To form a strand of DNA, nucleotides are linked in chains, alternating between phosphate and sugar groups.

Thus, the sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.
