<h2>Answer:</h2>

Option B) The parent cell has 24 chromosomes.

<h2>Explanation:</h2>

This is because:

In Asexual reproduction only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information. As a result, the offspring are genetically identical to the parent and to each other.
The parent cell simply divides to form two daughter cells that are identical to the parent. In sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote.
Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation, and hence the number of chromosomes remains same.

Result: The number of chromosomes remains same in asexual reproduction.

Why do resistant bacteria multiply faster after a patient has taken antibiotics compared to a healthy person who has not taken a

Alenkasestr [34]

Answer:

When patient takes in antibiotics the resistance bacteria gets a competitive survival advantage over the normal sensitive bacteria and hence grows faster.

Explanation:

Bacteria can acquire resistance by taking in plasmids containing MDR (Multi-Drug Resistance) gene cassettes. The MDR genes produces proteins that can:

Render the antibiotic ineffective to act on its target by inducing chemical modifications on the drug.
Promote efflux of the drug from the bacterial cell so that the drug cannot act upon its target.

When a healthy person ( having no prior exposure to the antibiotic) is infected by bacteria ( both sensitive and resistant varieties):

A competition develops for the host cells and nutrients between the sensitive and the resistant variety.
This mutual competition restricts either of the sensitive or resistant bacterial strain to grow profusely.

When a person (having prior antibiotic exposure), gets infected by bacteria ( both sensitive and resistant varieties) and is exposed to the same antibiotic:

The sensitive variety, due to its sensitivity towards the drug, gets killed.
The resistant variety, due to its MDR genes, bypasses the lethal effect of the drug and survives.
These surviving resistant bacteria can now infect all the available host cells and utilise all the available nutrients without facing any competition and multiply rapidly.

mendel realized that the principles of probability could used to blank the results of genetic crosses.

Degger [83]

Hey my friend did this one on Answer.com
<span>
Whenever Mendel performed a cross with pea plants, he carefully categorized and counted the many offspring. Every time Mendel repeated a particular cross, obtained similar results. For example, whenever Mendel crossed two plants that were hybrid for stem height (Tt), about three fourths of the resulting plants were tall and about one fourth were short. Mendel realized that the principles of probability could be used to explain the results of genetic crosses.</span>

PLEASE HELP!!!!! I NEED PERSON GOOD WITH AP BIOLOGY!! I WILL GIVE BRAINLIEST PLS!!!

sergey [27]

Answer:

if crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes. Meaning they are mixed.

Explanation:

If crossing over doesn't occurs then you wouldn't really mix the 2 parental alleles so you couldn't have a genotype without mixing.

Sorry if im wrong!
