Answer:

Option (B) and (C).

Explanation:

Anxiety disorders may be characterized as the mental health disorder that are characterized by the feelings of worry and panic. The symptoms of anxiety disorder are restlessness and stress.

Various biological factors are involved in the development of the anxiety disorder. The decreased levels of the GABA neurotransmitter is mainly responsible for this disorder. The enlarged fluid filled spaces called hydrocephalus are indirectly involved in the anxiety disorder.

Thus, the correct answer is option (B) and (C).

What will most likely happen if a person does not consume the minimum daily requirement of carbohydrates
Mice21 [21]

  If a person does not consume the minimal daily requirement of carbohydrates than the body will start to use the fat and proteins in the body so that it can produce energy. The carbohydrates are the primary energy source in the body, so the lack of them makes the body low on energy, and also it makes it harder to think and to remain active. If this process continues for a prolonged period of time, than it causes the building up of ketones in the blood, which results in ketosis.

Which of the following best explains the difference between micro and macro evolution? A. Microevolution is based on ideas, whil
gtnhenbr [62]

Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.

Explanation:

Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s
inn [45]

Answer: 1. S = 0.77

              2. R = 0.14

Explanation:

1. <u><em>Selection</em></u> <u><em>differential</em></u> is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. <em><u>Response</u></em> <em><u>to</u></em> <em><u>Selection</u></em> is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. <em><u>Heritability</u></em> is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

h^{2}=\frac{R}{S}

h^{2}=\frac{0.14}{0.77}

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.
