In mitosis, 1.)__________ parent cell(s) divide into 2.)__________ daughter cell(s).
nydimaria [60]

Answer:

The correct answer is 2.) 1 , 2

Mitosis is a type of cell division in which single parent cell divides into two daughter cells with equal number of chromosomes as in the parent cell.

It occurs in somatic cells of the body for growth and repair of the tissue.

It maintains the chromosomal number between parent and daughter cells and it is the reason that it is also called as equational division.

1. What percentage of puppies would have the same genotype as the<br> parents, Ww?
wolverine [178]

Answer:

50%

Explanation:

This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.

Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.

Why is it important to stain youngcultures of bacteria with<br> the grain stain?
uranmaximum [27]

Answer:

Because older cultures of gram-positive bacteria tend to lose their ability to retain crystal-violet in the peptidoglycan of their cell walls and can be confused with gram-negative bacteria.

Explanation:

Gram staining is used to differentiate between two major groups of bacteria. Gram-positive and gram-negative, these bacteria differ in the amount of peptidoglycan in their cell walls. Gram-positive bacteria have a higher amount of peptidoglycan, which absorbs the violet crystal complex used in gram staining, staining them purple/violet. Old cultures of gram-positive bacteria tend to lose the ability to retain the violet crystal and are stained by safranine, staining them red/pink and appear to be gram-negative.

How do bacteria maintain their internal ph despite the ph of the environment in which they grow?
ipn [44]
The answer to this question would be: by producing buffer

The pH of optimal growth of bacteria might be different. Some bacteria can grow in an acid condition called acidophile, other live in base condition called alkaliphiles and the rest live in neutral pH condition called neutrophiles. The bacteria can maintain their internal pH by producing acid, base or buffer. If the surrounding pH is too acid, the bacteria can reduce the H+ concentration by producing base. If the condition is too alkali/base, the bacteria can produce acid by doing fermentation.
