Greg says that he usually eats 1 medium carrot every day to ensure that he's consuming enough vitamin A. Today he said he didn't

eat any carrots and is worried that there is not enough vitamin A in his system. What would you say to Greg to allay his fear?
A) "Take a vitamin A supplement as soon as you can!"
B) "As long as you eat some chicken tonight you will not develop chicken eyes."
C) "Well, there isn't any vitamin A in carrots so you probably haven't consumed vitamin A for some time now."
D) "Don't worry; fat-soluble vitamins are stored in the body. It takes a lot longer than one day to develop any adverse effects.

Answer:

The correct option is D.  "Don't worry; fat-soluble vitamins are stored in the body. It takes a lot longer than one day to develop any adverse effects.

Explanation:

Fat-soluble vitamins can be described as those vitamins that can dissolve in fats and can be stored in the body in the form of fat-soluble vitamins. Energy is stored in the body for long terms in the form of fats.

The body does not require vitamins A, D, E and K regularly hence, they are stored in the fat tissues. Depletion of these vitamins in the diet for a day would not cause any adverse effects.

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually
lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) <em>Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. </em>

The benefit of reproducing sexually is that the risk of mutation is lower.

B) <em>Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.</em>

<em />

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.  

The hypotheses that would least likely aid the scientists to answer the question is <u>option D</u>.

Need help I will give you 20 points plsss
dybincka [34]

Answer:

III3 will be "pp" lower case p

II2 will be Pp

Explanation:

As we know the trait is caused by dominant alleles. III3 is not affected so she will have two recessice alleles so 2 lower case p.

III2 is affected so the person will have one dominant allele P and one recessive. The dominant is from the father and the recessive is from the mother.

Hope that helps

eduard

The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall serving to protect the bacteria and which is not easily washed off.

<h3>What is the bacterial capsule?</h3>

The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall and which is not easily washed off.

The bacterial capsule is a layer of polysaccharides which are found outside the cell envelope, therefore, it is regarded as being part of the outer envelope of a bacterial cell.

The bacterial capsule is associated with being the cause of various bacterial diseases.
