Using the concept that :
<span>The skin cell has twice the number of chromosomes as the sperm cell has.
</span>Hence,
<span>The sperm cell has 39 chromosomes.
The skin Cell will have = 39 x 2
                                    = 78 </span><span>chromosomes.</span>

Answer:

78 chromosomes can be expected in the skin cell

Explanation:

The sex cells i.e sperm and ova cells are haploid in dogs. Being haploid means, the number of chromosomes is "n".

While a skin cell in dogs in diploid which means that the number of chromosomes is equal to twice the chromosomes in haploid cells i.e "2n"

Hence, if the total number of  chromosomes in haploid sex cell is "n" or "39"

Then the number of chromosomes in diploid skin cell is equal to "2n"

or

2 * 39\\= 78

A person with prediabetes has a fasting blood glucose level of _____.
vlada-n [284]

Answer;

C. 100 - 125 mg/dL

A person with prediabetes has a fasting blood glucose level of 100-125 mg/dL.

Explanation;

-A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal.

-A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L) is considered prediabetes. This result is sometimes called impaired fasting glucose. A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates type 2 diabetes.

explain how repressible and inducible operons differ and how those differences reflect differences in the pathways they control
Sonja [21]

Answer

Operons are cluster of coordinated genes, including structural genes, an operator gene, and a regulatory gene.

Explanation:

In the The repressible operons, The transcription is usually on and repressor is in inactive form, So the specific genes are transcribed. While a regulatory molecule act as corepressor and binds to repressor protein to activate it. The repressor protein cause the inactivation of repressible operon (as the name indicate). E.g., Tryptophan Repress the trp operon.

A high level of product act as regulatory molecule (Corepressor) and turn off the operon, So anabolic pathways or synthesis of essential components are controlled by repressible operon.

In the Inducible operons, the transcription is usually off and repressor is in active form. So there is no transcription of genes. Specific Metabolite cause the activation of operon  e.g lactose cause the induction of lac operon.

As a metabolite induces the operon, So they control the Metabolic pathways or breakdown of a neutrient.

In a small hospital in yokadouma, cameroon, a 24-year-old woman named prudence died in childbirth. which would not be considered
Misha Larkins [42]

Options for the question have not been given. They are as follows:

A. a lack of urban health care capacity

B. cultural disregard for women and women's health

C. prudence's family medical history

D. a lack of previous medical problems

Answer:

C. prudence's family medical history

Explanation:

Sociological factors include the factors related to human society. These factors stem from the way a society functions and effects the people which are a part of it. The way the society is structured and developed, impacts the people.

Prudence died during childbirth. There can be many sociological causes of her death like low status of women or poor medical facilities in her society. However, her family medical history will not be considered a sociological factor. Family medical history also depends on other factors like genetic composition of the family which is not a sociological factor.
