Why is the endoplasmic reticulum important for survival?

Answers

Answer 1

The endoplasmic reticulum (ER) is an organelle that plays crucial roles in a number of cellular activities, including as protein secretion, lipid production, and intracellular calcium homeostasis which are necessary for cell survival and regular physiological operations. The cell cannot exist without the endoplasmic reticulum.

Endoplasmic reticulum is the network of tubes and sac-like structures in a cell's cytoplasm, which resembles gel. The endoplasmic reticulum transports chemicals and proteins. The endoplasmic reticulum's outside surface can be either smooth or rough. The rough endoplasmic reticulum produces the necessary proteins for the cell and has several ribosomes on its surface. Other compounds that the cell requires, such as lipids (fats) and carbohydrates, are produced by the smooth endoplasmic reticulum (sugars). A cell organelle is the endoplasmic reticulum.

how does the thyroid gland help maintain and regulate calcium?

Answers

Answer:

When the calcium level is high in the bloodstream, the thyroid gland releases calcitonin. Calcitonin slows down the activity of the osteoclasts found in bone. This decreases blood calcium levels. When calcium levels decrease, this stimulates the parathyroid gland to release parathyroid hormone.

Which of the following is correct about mutations and genetic variation?

It must be present in a population before natural selection can act upon the population.
It arises in response to changes in the environment.
It tends to be reduced when diploid organisms produce gametes and reproduce.
It is created by the direct action of natural selection.

Answers

Answer:

a. It must be present in a population before natural selection can act upon the population.

Explanation:

Genetic variation is the difference in the DNA sequences in individuals, which makes a member of a species different from another member of the same species. It can also be said to be the differences in the genetic make up of individuals of a species population.

Genetic variation must be present in a species population before evolutionary mechanisms, such as evolution, can occur. Genetic variation must be present in a population of a species before natural selection can act upon the population, as natural selection can only increase or reduce the frequency of alleles present in the species population already.

Genetic variation in a population of species is important for natural selection to occur.

The true statement is that; "genetic mutation must exist before natural selection can act on it."

What is natural selection?

The term natural selection refers to the fact that traits that are more favorable to enable an organism to survive and reproduce tend to persist in the population.

These traits usually occur due to genetic mutations. In a population, genetic mutation must exist before natural selection can act on it.

Why does the grass look green under sunlight and black under the moonlight?

Answers

Answer: The original colour of grass is green because of photosynthesis. But in terms of reflection, it looks green because the sunlight reflects the green colour off the grass, so we see it as green.

Explanation: Sun appears white, but it is made up of the colors: red, orange, yellow, green, blue, indigo, and violet. When white light hits an object, it absorbs some colors and reflect the others. Grass appears green because it absorbs all the wavelengths except green. Green is reflected off the grass, so we see grass as green. The moon doesn’t have light of its own, the moon lights up because of the sun. So at night, as the light of the sun doesn't reach the grass directly because of the moon, it doesnt reflect any color off the grass, and so our eyes detect grass as black.

When it is summer in the U.S, why is it winter in South America?

Answers

Answer:

the suns on the other side of the earth at the time

Explanation:

hope it helps :)

Answer:

The Earth is tilted at an angle of about 23 degrees, which means that depending on where Earth is on its orbit, one pole will be getting more hours of light (summer) and one will be dark (winter).

Explanation:

Also, the earth is tilted on it's axis so more direct rays of sunlight hit the southern hemisphere making it summer in that hemisphere while it is winter in the northern hemisphere.  Six months later, this reverses, and more direct rays hit the northern hemisphere.  That's why it's summer here while it's winter there.  

The earth's distance from the sun has nothing to do with it.  It's all about the axial tilt.
