How can mutations affect evolutionary processes? A) Mutations are novel genes that increase an organism’s fitness in the environment. B) Mutations are new genotypes that cause an organism to be more poorly fit due to non-functional essential genes within its genome. C) Mutations are changes in the genome that can code for new phenotypes that may be selected for or against by the environmental pressures. D) Mutations are changes to protein structure that create new genotypes that can be selected for or against by the environmental pressures.

Answers

Answer 1

Answer:

Answer:

Option C

Explanation:

Option A is incorrect as mutations may be detrimental to the organism and are not always beneficial. Option B is incorrect as there are instances where mutations may enable organisms to be better adapted to the environment. Option D is incorrect as genotypes are not selected for or selected against by environmental pressures, it is only the phenotype (exhibitable/ visible traits) that can be selected for or against, hence option C is the answer.

Systemic circulation is the movement of blood between the heart and the __________

Answers

Answer:

Body

Explanation:

Answer:

Systemic circulation is the movement of blood between the heart and therestofthebody.

Explanation:

The oxygenated blood will pass through the left ventricle to arteries then the capillaries of the body. After the oxygenated blood is distributed to all parts of the body, the now deoxygenated blood will return through a network of veins thus, to the right atrium of the heart.

Use the models that you created in Lesson 2, Lab 1 to help you answer the following question. How does an increase in cell volume impact the diffusion of materials through the cytoplasm?

Answers

The cytoplasm is a thick, liquid residing between the cell membrane holding organelles.

The larger the cell, the longer time it takes for materials to travel.

Is how an increase in cell volume impacts the diffusion of materials through the cytoplasm.

Increasing the cell's volume would reduce the efficiency of the diffusion of materials through the plasma membrane into the cytoplasm of the cell.

On the other hand, increase the surface area and decreasing the volume oft the cell would increase the rate of diffusion across the plasma membrane.

A low secretion of luteinizing hormone (LH) in the normal male adult would cause A. shrinkage of the anterior pituitary gland
B. decreased testosterone secretion
C. excessive beard growth
D. increased spermatogenesis

Answers

Answer:

A low secretion of luteinizing hormone(LH) in the normal male adult would cause B. decreased testosterone secretion.

Explanation:

For males the normal range is 1.24 -7.8 IU/L. If LH levels are below the normal range it may indicate a pituitary gland problem. Their pituitary gland may not be making enough LH which may lead to low testosterone.

Hypogonadism is a testicular disorder associated with low testosterone. Low testosterone levels can cause a variety of problems including diminished muscle mass & decreased sex drive as well as decrease in the physical as well as mental energy.

Final answer:

Luteinizing Hormone (LH) in males stimulates the production of testosterone. If LH secretion is low, it would result in decreased secretion of testosterone.

Explanation:

The secretion of Luteinizing Hormone (LH) plays a significant role in the male reproductive system. A low secretion of LH in a normal adult male most likely impacts the production of testosterone because LH stimulates the testes to produce this hormone. Therefore, a decrease in LH secretion would logically lead to a decreased secretion of testosterone (Option B). This decrease in testosterone can further lead to a reduction in sex drive, decreased muscle mass, and other sexual and physical changes.
