PLEASE HURRY !!!!!!How does plate tectonics affect climate?
(Points : 1)
(a)increased earthquakes

(b) changing ocean circulation

(c) extinction of animals

(d) changing earth's position on its axis

Answers

The correct answer is - (b) changing ocean circulation.

The ocean currents are very important when it comes to the climate. The movement of the tectonic plates though, over time, is changing their patters. The changes appear because of the movement of the land masses, so there can be situations where the ocean currents are interrupted by a moving land mass, or more space to be opened up for an already existing ocean current with the moving away of a land mass of its path. Those movements and spaces in the water bodies are affecting the direction and the temperature of the ocean currents, and those changes will reflect on the climate on the regions that they are influencing.
at human scale by increased earthquakes and at the geological scale by changing ocean circulation 

What are the main functions of polysaccharides in plants?

Answers

Polysaccharides are complex sugars or carbohydrates.

Types Of Polysaccharides

Cellulose: The cell wall of the plants is made up of cellulose.

Starch: It is formed by the condensation of amylose and amylopectin.

Glycogen: It is made up of a large chain of molecules.

Inulin: It is made up of a number of fructofuranose molecules linked together in chains.

The innermost layer of an artery or vein is called the __________.

Answers

Artery and veins are the blood vessels responsible to carry oxygenated and deoxygenated blood respectively. The innermost layer of these blood vessels is referred to as tunica interna.

What are blood vessels?

Blood vessels are responsible for circulating blood from heart to other body parts and vice-versa.

These carry oxygenated blood from heart to other cells and deoxygenated blood from cells to lungs and then to heart.

These are of two types, namely artery and vein.

The innermost layer of an artery or vein is referred to as the tunicainterna.

Thus, the correct answer is tunica interna.
