<h3><u>Required </u><u>Answers</u><u>:</u></h3>

a) The rock above shown in the picture is <u>pumice rock</u> because it is having abundant pores on its surface. It is the only rock found with numerous pores.

b) The pumice rock is an igneous rock and we know that igneous rocks ar made from the molten magma. When the lava comes out, and cooled down it forms the igneous rocks. During this process, if there are air spaces accumulated, they form pumice rock.

c) The pumice rock is known as porous rock because it contains many pores due to air spaces inside it. This is h hence very light and floats on water.

d) The pumice rock is used as a scrubber because of its lightness and porosity. It is also used as an abrasive .

It is possible for two parents each with brown eyes to produce a blue-eyed child.
elena55 [62]

Answer:

True

Explanation:

The color of the baby's eyes is influenced by the genetic inheritance (of the genes transmitted by the mother and father) and the amount of melanin (brown or black pigment whose type and amount is encoded in the genes) found in the iris.

Eye color is controlled by at least three genes, although researchers still only understand the role of two of them. Determining eye color is an extremely complex process and there are several conditioning factors and genetic combinations that can influence the final color.

The more melanin, the darker the color of eyes, skin and hair. If parents have both brown eyes, it is natural for their children to have the same color. However, there may be a genetic influence from an ancestor and the child expressing a different color.

If the presence of melanin in the iris is reduced, the baby will have blue eyes, even if father and mother have brown eyes. If the presence of melanin is higher, the eye color will be green or hazel. When there is a large production of melanin, the eyes are brown, predominant color over green or blue and therefore more common. The least common color is green.

How does energy flow through organisms
Natalka [10]

Answer:

Energy "flows" through the ecosystem in the form of carbon-carbon bonds. ... This process releases the energy, which is either used by the organism (to move its muscles, digest food, excrete wastes, think, etc.) or the energy may be lost as heat. The dark arrows represent the movement of this energy

Usually ____ are the food molecules broken down during glycolysis
Leya [2.2K]

Hello :)

So first the glycolysis process is the process when a glucose molecule  is broken down by enzymes in order to make pyruvate, this acid provides energy to cells.

So, now since we know what glycolysis is, we know that it breaks down glucose which is indeed basically sugar.

Therefore the answer here would be 4. simple sugars.
