Discuss the ways in which characteristics that suit a species for survival are transmitted from one generation to the next (disc
mina [271]

      Well, the first thing you need to understand to answer this question is Darwin's theory.

      What happens is that, for example, a species of giraffe has a small neck, what happens to it is that this species can't get the food on top of the trees, and then, this species will most likely die in a couple of time. But through mutation, this species can generate another one that fits well into that environment, being capable to get food on the ground or even with a bigger neck, and by that, the survival of the species is guaranteed for now. Let's think about humans for a second, we are a species that went through evolution as well as all the species on earth right? But how did that happen?           It's easy, if one of our ancestors for example, didn't have the right DNA/genes that gave us a feature that protected us from some diseases, we would probably be dead.

        And be careful, a gene can be anywhere in a chromosome, that's why it's so hard to study and map it. The same thing happen to cells, if they dont adapt well, they die or adapt on the next generation.

The peptidoglycan of bacterial cell walls contains a carbohydrate matrix linked together by short chains of:__________
V125BC [204]

The peptidoglycan of bacterial cell walls contains a carbohydrate matrix linked together by short chains of fatty acids.

<h3>Write about Bacterial cell wall.</h3>

In bacteria, the cell wall forms a rigid structure of uniform thickness around the cell and is responsible for the characteristic shape of the cell (rod, coccus, or spiral).

Inside the cell wall (or rigid peptidoglycan layer) is the plasma (cytoplasmic) membrane; this is usually closely opposed to the wall layer.

It is also important to note that most bacteria (about 90%) have a cell wall and they typically have one of two types: a gram positive cell wall or a gram negative cell wall.

Both gram positive and gram negative cell walls contain an ingredient known as peptidoglycan (also known as murein).

This particular substance hasn’t been found anywhere else on Earth, other than the cell walls of bacteria.

The bacterial cell wall performs several functions as well, in addition to providing overall strength to the cell. It also helps maintain the cell shape, which is important for how the cell will grow, reproduce, obtain nutrients, and move.

It protects the cell from osmotic lysis, as the cell moves from one environment to another or transports nutrients from its surroundings.

Before the application of dna sequencing to fossils, which species concept was most useful for distinguishing human fossils?.
Bas_tet [7]

Explanation:

For paleontologists, however, the Phylogenetic Species Concept is most frequently employed, simply because we just can't test reproductive isolation in fossil taxa.
