Mary Morgan has just been brought into the emergency room of City General Hospital. She is perspiring profusely and is breathing

timurjin [86]

Answer:

The insulin must be administered.

Explanation:

In the given question the Mary has the acidosis that is the level of pH in the blood have dropped below 7.

It is also provided that the smell of her breath is fruity due to the accumulation of fruity smell molecules called ketones which could be the result of the ketosis. Ketosis occurs when the cellular respiration uses fat as a substrate instead of the carbohydrate. This shows Mary has a condition called ketoacidosis.

The increased level of the glucose in the blood shows that the glucose is not absorbed by the cell which involves the insulin therefore the doctor should administer the insulin drug to the patient.

Thus, insulin is the correct answer.

. If a person comes in contact with this same virus years later, what does our body produce to get rid of or kill the virus

borishaifa [10]

If a person comes in contact with this same virus years later, our body produces antibodies to get rid of or kill the virus

Explanation:

When a person is infected by a virus, the infected person's body develops antibodies as an immune response to act against the virus. Antibodies are produced as part of humoral immunity.

Antibodies work by neutralizing the viral activity, agglutination, phagocytosis or by complement system.

Antibodies are protein compounds which can recognize the invading pathogens and attack them.

Antigens or viral proteins in the virus leads to the production of antibodies in the host's body.

The specific antibodies triggers innate immune response upon detecting specific viral antigens when infected and will help the body to get rid of or kill the virus.

In a certain group of African people, 4% are born with sickle-cell disease, an autosomal recessive disorder. Heterozygous indivi

love history [14]

Answer:

the correct answer is C) 32%

Explanation:

Sickle-cell anaemia is an autosomal recessive genetic disorder. Individuals with the homozygous recessive have sickle-shaped blood cells. Whereas, individuals with heterozygous are only carrier of sickle cell trait. The carrier individuals are resistant to malarial parasite and do not have malaria.

As per the question, 4% of an African population is born with sickle-cell disease, then the percentage of the population is heterozygous and resistant to malaria will be:

Hardy-Weinberg formula is equilibrium,

p² + 2pq + q² = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p2 = percentage of homozygous dominant individuals

q2 = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

Given, homozygous recessive for this gene (q2) is 4% which is 0.04, the square root (q) is 0.2 (20%) then p should be 1-0.2 = 0.8 (20%).

Thus, the frequency of heterozygous individuals = 2pq.

2 (0.8 x 0.2) = 0.32 (32%).
