Answer:

A protein's specific shape determines its function.

Explanation:

If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.

Independent assortment of chromosomes is a result of _____.
Ann [662]

Answer:

the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.

Explanation:

Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.

This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.

Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.

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.

Why is water important, describe the special properties of water? Provide examples.
Sveta_85 [38]

Answer:

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. ... The stream of water bends due to the polarity of water molecules.

Arrange the order of events for the internalization of LDL particles into cells:
ElenaW [278]

Answer:

The correct answer is "5-1-3-2-4".

Explanation:

Internalization of LDL particles into cells, is needed to form the intracellular vesicles known as endosomes. The order of events that allow for this process are:

5) LDL receptors migrate to the cell surface and cluster in clathrin-coated pits. Clathrin acts directing the receptors to the cell membrane region where endosomes are formed.

1) A combination of cholesterol and apolipoprotein binds to LDL receptors and becomes internalized as endocytotic vesicles. Once the receptors are in the proper cell membrane region, cholesterol and apolipoprotein are bound and internalized.

3) Several endocytotic vesicles fuse to form an endosome.

2) The environment of the endosome becomes acidic, which causes the LDL to dissociate from its receptor; additionally, the endosome fuses with a lysosome. LDL should be dissociated from its receptor since it is going to be degraded in the following step.

4) The LDL particle is degraded by the lysosome. This takes place after endocytosis, when LDL particles are transported into lysosomes once they are fused, cleaving the cholesterol esters into cholesterol and fatty acids.
