The substance that helps keep the integrity of the bacterial cell wall intact is known as the peptidoglycan. Others also refer to is it as murein or mucopeptide. The bacterial cell wall is necessary for survival because of the high internal pressure present inside of bacteria. Under normal conditions, if the cell wall is removed the bacterial cell will burst.

The peptidoglycan is a layer that can be used to distinguish gram positive bacteria from gram negative ones. G(+) bacteria have a thick layer of this while G(-) have a thinner ones.

Problem #1
Arisa [49]

Answer:

9/16  Kinked tail, normal growth

3/16 Kinked tail, obese growth

3/16 normal tail, normal growth

1/16 normal tail, obese growth

Explanation:

Kinked tail (K) is dominant over normal tail (k) and normal growth (N) is dominant over obese growth (n). Two mice that are heterozygous for both traits (KkNn) are crossed:

        KkNn    x    KkNn

offspring:

<em>9/16</em><em> K_N_ - Kinked tail, normal growth</em>

<em>3/16</em><em> K_nn - Kinked tail, obese growth</em>

<em>3/16</em><em> kkN_ - normal tail, normal growth</em>

<em>1/16</em><em> kknn - normal tail, obese growth</em>
