In humans, what determines the sex of offspring and why?.

Answers

Answer 1
Answer:

Females have two X chromosomes in their cells, while males have both X and a Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome. This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs.

after death, the cornea absorbs fluid and becomes opaque. in a living person, the cornea is translucent due to _______________.

Answers

Given what we know about human anatomy, we can confirm that the cornea of a live human is translucent due to the arrangement of its collagen fibers and the lack of vascularity.

One important factor in the translucent nature of the cornea and lens is its lack of vascularity. This area of the eye has few if any vascular components, which contributes to its lack of pigment.

However, the main component that contributes to the translucent nature of the human cornea is its very specific arrangement of collagen fibers.

The bundled nature of these fibers, together with the water content of the cornea, allow it to remain translucent.

Both the mother and father of a son with colorblindness have normal vision. From whom did the son inherit the gene for colorblindness

Answers

Answer:

The blind son inherited his gene for colorblindness from his father.

Explanation:

The X chromosome is where color blindness is most frequently inherited as a recessive trait. In genetics, this is referred to as X-linked recessive inheritance. As a result, men tend to be affected by the illness more frequently than women (8% male, 0.5% female).

What are the characteristics of colorblindness inheritance?

There is a 50% chance that the sons of a color-blind father and a mother who has the gene will also be color-blind. However, their daughters will have a 50% risk of having the condition and a 100% chance of carrying the gene.

The 23 chromosome is known as the “sex chromosome,” and it is passed from mother to son. Red/green color blindness is the most common type of this condition.

As it aids in identifying sex, the 23rd chromosome is known as a sex chromosome.

Therefore, The blind son inherited his gene for colorblindness from his father.

Why do the alveoli fill with fluid.

Answers

Answer:

Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.

Explanation:

Answer:

The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants.                                        Explanation:     hope this helps
