Answer: The correct answer is- B) The dominant allele determines the trait.

Allele can be described as an alternative form of a gene. It exists in two forms that is dominant and recessive allele.

Dominant allele (depicted by capital letter) is the one that masks the expression of recessive allele (depicted by small letter) .

Thus, dominant allele determines a trait (such as Tt for tall pea plant) that is a particular characteristic of an organism.

1. The sensory layer of the eye.

Keith_Richards [23]

Answer:

The correct answers are:

1. The sensory layer of the eye. B) Retina

2. The structure most responsible for focusing light rays that enter the eye. D) Lens

3. Helps maintain the intraocular pressure; located in the anterior part of the eye. A) Aqueous humor

4. Area of greatest visual acuity. C) Fovea centralis

Explanation:

1. The sensory layer of the eye.

The retina covers the inside of the eyeball. It is considered as the sensory organ of the eye, where the perceived images are projected, are processed in the form of a nerve impulse that leaves the optic nerve.

2. The structure most responsible for focusing light rays that enter the eye.

The lens are the transparent structure inside the eye that focuses light rays in the central part of the retina.

3. Helps maintain the intraocular pressure; located in the anterior part of the eye.

The aqueous humor, is a transparent aqueous fluid secreted by the ciliary body, this liquid derived from the blood plasma, distributes oxygen and nutrients to the upper part of the eye and eliminates residual products. The dynamics of production and elimination of aqueous humor is very important to keep intraocular pressure (IOP) within normal limits.

4. Area of greatest visual acuity.

The fovea, or also known fovea centralis, is the center of the visual field, it is a narrow area of the retina that only contains cones. Its function is to help us have a vision as clear as possible with all kinds of details and precision.

Which of the following statements about drug resistance is FALSE?

ZanzabumX [31]

Answer:

The false statement is e. It is found only in gram-negative bacteria.

Explanation:

Drug resistance is a condition that is usually developed in bacteria because of the wrong use of medicines. This condition can cause a mutation and can be transferred with horizontal gene exchange, that does not require breed and it can happen between two grown bacteria. As it happens in all species of bacteria, therefore it's not only found in gram-negatives.

Surprisingly, in a number of reactions in which either ATP or GTP are involved, the critical event is not due to the hydrolysis

kkurt [141]

Answer:

The correct answer is option d. "phosphorylation of glucose".

Explanation:

The phosphorylation of glucose is one of the most important catabolic reactions that allow to obtain energy from sugars. This reaction is the first step of glycolysis and avoid cells to lose sugars by diffusing back to its transporter. The phosphate used to phosphorylate glucose comes from the hydrolysis of one of the three phosphate of adenosine triphosphate. Therefore, phosphorylation of glucose is a processes where ATP hydrolysis is directly involved.
