<span>There are three basic chemical components of DNA - 1. Four "Nucleic acids", 2. Deoxyribose sugar, and 3. Phosphate backbone. The overall shape of the molecule is a double-stranded, double helix. It looks a bit like a spiral staircase wrapped around a spiral staircase. Phosphate groups outside, nucleic acids inside the helix,</span>
The correct answers are:
- plates moving;
- breaking rocks;
- movement bellow the surface;
The earthquakes are a direct result of the plate tectonics. In order for an earthquake to appear, there should be a geologic activity caused by the movement of the tectonic plates. The movement of the tectonic plates causes a lot of pressure on the rocks. The rocks eventually break at certain places under the pressure. A they break, there's movement bellow the surface, or rather inside the crust, also referred to as adjustment. That movement and the release of power from it, causes lot of strong vibrations. The vibrations spread out and start shaking the ground in the surrounding area, which is actually the earthquake itself.

4. Cellular respiration
Answer:
<u>1. Homeostasis</u>
Explanation:
Sugar level in humans is regulated by "Insulin" and "glucagon" hormones that are secreted by the pancreas. Both hormones work in a balanced way to regulate the blood sugar level within a specific range if the sugar levels spike or drop.
Together,<u> </u><em><u>insulin and glucagon help maintain a state known as homeostasis</u></em><em>.</em> By definition, homeostasis is the maintenance of the internal environment of cell/body with respect to the external environment. Thus, homeostasis maintains a relatively stable state that persists despite changes in the world outside.<u> When blood sugar is too high, the pancreas secretes more insulin which acts to trigger breakdown of sugar thus reducing its level. By contrast, when blood sugar levels drop, the pancreas releases glucagon to allow conversion of macromolecules to simple sugars and raise its level.</u>
