Fifty percent of the offspring produced by a cross between pea plants have seeds with a wrinkled (r) appearance caused by the pr
tangare [24]

Answer:

The correct option is B. Rr × rr

Explanation:

To illustrate the results, lets make a cross between RR and rr.

      r         r

R    Rr       Rr

r      rr        rr

   

The results from the following punnet square show that there will be a 50% probability that the offsprings will have heterozygous genotype Rr and they will be round.

The results from the punnet square show that there will be a 50% probability that the offsprings will be recessive and hence will have wrinkled seeds.

Mammals in Australia are called marsupials, and diverged from the placental mammals very early in mammalian evolution. Australia
mamaluj [8]

Answer:

The correct answer is homologous.

Explanation:

A structure that is derived from a common ancestor is called homologous structure. So homologous structure is the characteristic of divergent evolution that means divergent evolution give rise to homologous structures.

So as the marsupials are mammals that were diverged from placental mammals very early in mammalian evolution, the membranes of skin that allow Australian sugar gliders and North American flying squirrels to glide are homologous because divergent evolution gives rise to homologous structures.

The function of these homologous structures can be the same or can be different. Therefore the correct answer is their membrane are homologous.

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.
