Answer:
A. When two tectonic plates start to push into each other they can rise up and build mountains, or sink under and create deep valleys.
Explanation:
It is true
Answer:
The correct answer is-a polysaccharide found in animals
Explanation:
Glycogen is a polysaccharide which is a highly branded form of amylopectin. In glycogen glucose residues are joined together by α1-4 glycosidic linkage and α 1-6 branching points occurs after every 8-10 glucose residues.
Glycogen is the main carbohydrate storage form of carbohydrates in animals. Glycogen is mostly present in liver and muscles. It breaks down into glucose and provide energy to the animal during the physical activity. Therefore glycogen is polysaccharide found in animals.
Answer:
A) they help transport some substances through the membrane.
Explanation:
The membrane proteins that span the bilayer of phospholipids help in the transport of polar, large and charged substances across the membrane. The nonpolar core of the membrane does not allow these charged and polar substances to pass through. Proteins serving as channels form pores to allow movement of the specific substances.
On the other hand, carrier transport proteins of the membrane bind to the substances present at one side of the membrane and deliver them to the opposite side.
The term in question is referred to as osmoregulation.
Since water and its soluted metabolites are key to the survival and normal function of the cell, there are many membrane proteins that regulate the exchange of water, ions and other osmolites between the cell and its surroundings.
Answer:
B) Atoms of elements in the sun combine to release energy.
Explanation:
The process is called fusion, where atoms collide violently and release energy in the process, thus making new kinds of atoms.
