Explain how major ocean currents influence the coastal climates of the regions that border them

KIM [24]

So, when there is an ocean current coming from for example the gulf of Mexico onto new england-
it will be carrying warm waters, so since new england has a cold climate and you are bringing warm water with the ocean current it affects the coastal climate.

Some types of muscular dystrophy are X-linked recessive disorders. A mother who is a carrier for muscular dystrophy has children

marissa [1.9K]

D gene is an X-chromosome-linked gene. a) 100% will have the disease, XdY // 0% will be carriers. b) 0% will have the disease // 100% will be carriers, XDXd.

<h3>What are the séx-linked genes?</h3>

These are genes that can be found only in the X-chromosome. The inheritance pattern expressed by these genes varies from the one expressed by genes located in autosomal chromosomes.

In the exposed exampe,

- muscular dystrophy are X-linked recessive disorders

- woman ⇒ carrier for muscular dystrophy ⇒ heter0zyg0us ⇒ XDXd

- man ⇒ doesn’t have muscular dystrophy ⇒ X-chromosome with the dominant allele ⇒ XDY

- XD ⇒ chromosome rarrying the dominant allele

- Xd ⇒ chromosomes carrying the recessive allele

Cross: Man x Woman

Parentals) XDY x XDXd

Gametes) XD Y XD Xd

Punnett square) XD Xd

XD XDXd XDXd

Y XdY XdY

F1) 1/2 = 50% of the progeny will express the normal phenotype, XD-

1/2 = 50% of the progeny will have muscular dystrophy, Xd-

100% of the girls will be normal and carriers, XDXd

100% of the boys have muscular dystrophy, XdY

a. What percentage of their sons will have the disease, and what percentage of their sons will be carriers?

Considering only boys,

100% of them will have the disease, XdY
0% will be carriers.

b. What percentage of their daughters will have the disease, and what percentage of their daughters will be carriers?

Considering only girls,

0% of them will have the disease,
100% will be carriers, XDXd

The highlighted structure is innervated by the ________ nerve.

kogti [31]

The highlighted structure is innervated by the <u>Optic</u> nerve. The correct option is c.

<h3>What is the optic nerve?</h3>

The optic nerve is essential for vision. It is a part of your central nervous system, which also includes your brain and spine. The optic nerve is responsible for transmitting electrical impulses from your eyes to your brain.

This sensory information is processed by your brain so that you can see. The optic nerve is a network of over one million nerve fibers that transmit visual data. One connects the back of each eye (the retina) to the brain. Optic nerve damage can result in vision loss.

Therefore, the correct option is c, Optic nerve.

Explain the difference between sex hormones and glandular stimulating hormones

bagirrra123 [75]

Answer:

Sex hormones are those hormones that within the endocrine system of the human being, are considered more directly involved in human sexuality, particularly in the processes of copulation and reproduction.On the other hand, glandular stimulating hormones are those that act on hormonal production in another endocrine gland, that is, they are stimulants, since they stimulate the corresponding glands.

Explanation:

Sex hormones are chemical substances secreted by the sex endocrine glands (the testes and ovaries) and subsequently released into the bloodstream, to be transported to the organs on which they exert their action (increasing or decreasing their activity).The production of hormones is regulated in many cases by a negative feedback system, which causes an excess of a hormone to be followed by a decrease in its production. The glandular stimulating hormones are transported to the blood to stimulate the corresponding glands (thyroid, adrenal cortex, and gonads) and these will be the ones that secrete various types of hormones (thyroxine, corticosteroids and sex hormones, respectively), which in addition to acting in the body, they feed back into the pituitary and hypothalamus to inhibit their activity and balance the respective secretions of these two organs and the target gland. For example, follicle-stimulating hormone encourages sperm production in men and stimulates the ovaries to release eggs in women. Luteinizing hormone and follicle stimulator work together to allow normal function of the ovaries or testicles.
