What can occur when too much groundwater is pumped out of underground aquifers?
Mnenie [13.5K]

Answer:

Pumping too much water too fast draws down the water in the aquifer and eventually causes a well to yield less and less water and even run dry. In fact, pumping your well too much can even cause your neighbor's well to run dry if you both are pumping from the same aquifer.

A product of the anterior pituitary gland that causes color changes in its target cells is ________. A. follicle-stimulating hor
Ludmilka [50]

A product of the anterior pituitary gland that causes color changes in it's target cells is melanocyte stimulating hormone (MSH) .

Hence the correct answer is option D .

<h3>What is the pituitary gland ? </h3>

Pituitary is known as the master gland of our body, because it controls and coordinates the development and functions of other endocrine glands. It is found in the base of the brain in a bony cavity called 'sella tursica' and is attached to the hypothalamus.

It has two parts - anterior pituitary ( also known as adenohypophysis) and posterior pituitary ( neurohypophysis).

<h3>What is anterior pituitary?</h3>

The anterior pituitary has two parts para distalis and pars intermedia. Of this , FSH, LH, TSH, ACTH etc., is released by pars distalis, and the only hormone from pars intermedia is the MSH .

  • FSH - Follicle Stimulating Hormone - Stimulates the growth of ovarian follicles for next menstrual cycle.
  • LH - Luteinizing Hormone - Induces ovulation of fully mature follicles and maintains corpus luteum.
  • TSH - Thyroid Stimulating Hormone - Stimulates secretions of  Thyroid gland.
  • MSH - Melanocyte stimulating hormone - acts on melanocytes ( cells with melanin, a pigment ) and regulates the pigmentation of the skin.

Hence from the above points ,we can conclude that MSH causes color changes in it's target cells.

So correct answer is option D .

In what ways are cellulose and starch similar to each other and in what ways are they different? Be specific in your comparison,
Tom [10]
By starch, I'm assuming you mean glycogen, or animal starch.
Similarities:
Both are polysaccharide molecules made from glucose molecules linked together in a long chain.
Both are storehouses of energy.

Differences:
Glycogen is made in animal cells and is the only form of starch animals can digest (unless they have certain microbes in their intestinal tracts to break down cellulose, which all herbivores need).
Cellulose is made in plant cells.

The bonds are a bit different; the molecules are isomers. Glycogen bonds with what is called an alpha 1,4 bond, meaning that the first carbon of one glucose molecule is bonded to the 4th carbon of the next glucose molecule, but in a way that puts the bonds in a shape that falls below the plane of the molecule, and allows branching.

Cellulose bonds with beta 1,4 bonds. The first and fourth carbons of adjoining glucose molecules are still connected, but the shape of the bond falls above the plane of the molecule and does not branch.

Since enzymes are specific to their substrates, the enzymes shaped to fit glycogen bonds do not fit on cellulose bonds, which is why animals cannot digest cellulose on their own. In herbivores, there are microbes in their digestive tracts which can produce enzymes to break these bonds so the glucose can be used. In carnivores and omnivores like humans, there is no enzyme to break down cellulose so it becomes 'roughage' in our diets. It passes through the digestive tract without being broken down.
