Why would you expect equal numbers of guanine and cytosine in a molecule of DNA, but not necessarily in a molecule of RNA?

Answer:

DNA is double-stranded, so there must be equal numbers of C and G because they pair to each other on the complementary strands.

RNA is only single-stranded, so there can be any number of C and G. They don't pair to each other, because there's only one strand.

How do mountain barriers modify rainfall patterns on Hawaii's Big Island and island of Maui?
Iteru [2.4K]

The explanation is given below

<u>Explanation:</u>

Hawaii's Big Island:

Mountain barriers play a significant role in modifying the air masses and topography affects the distribution of precipitation.

The orographic effect takes place on Hawaii's Big Island (i.e) the rising air makes the windward side of the mountains rainy and leeward side of the mountains dry.

Island of Maui:

In the Island of Maui, the high mean of rainfall is found on the windward side of the mountain slopes and the low mean of rainfall is found on the leeward lowlands and on upper slopes of the highest mountains.

 “The outer energy levels are full, but that doesn’t mean the inner ones are,” says a friend. How would you respond?
Anton [14]

He is WRONG

Explanation:

Any atom at the ground state has its orbital levels fill from the bottom (close to the nucleus) – up. The inner orbitals are of lower energy state and fill first because the atoms ‘likes’ to exist in the low energy and more stable state. Only when the atom is in an excited state do some of the electrons in the lower orbital levels shift to higher unfilled orbitals.

Contact [7]

According to the research, the correct answer is fiber composites. Because cell walls consist of a cross-linked network of long filaments embedded in a stiff surrounding material, they can be called fiber composites.

<h3>What are cell walls?</h3>

It is a network that covers prokaryotic cells and plant cells that is located outside the plasma membrane, helping to form the structure.

In this sense, since it is made up of a network of carbohydrates, phospholipids and structural proteins, and the different cell types of plants can be identified by their characteristics, they can be called fiber composites.

Therefore, we can conclude that cell walls are a network embedded in a matrix composed of carbohydrates and proteins.
