We need to have sunlight because without it you wouldn’t be able to make anything else
In the large rainfall is some water remains in the top of the soil the rest of this water is seeped into the ground.
<u>Explanation:</u>
- Mainly the absorption of water by the ground depends upon the nature and the fertility of the soil.
- When the ground receives the water it mainly accounts for the absorption and then there will be a runoff. The absorption helps to raise the level of groundwater for future usage.
- The amount of water that can get into the soil mainly depends upon the permeability of the soil surface. The water which can't infiltrate in the soil runs off into the water bodies.
- The water is an essential requirement for survival and the existence of biological organisms.
Answer:
D. Dynamic equilibrium
Explanation:
Equilibrium is when the amount of solution outside the cell is equal to the amount inside. A dynamic equilibrium is when this homeostasis is kept through a continuing process. Therefore, since homeostasis is constantly being maintained the solution will be equal on both sides of the cell.
Answer:
OH, H2O2 and O−2
Explanation:
Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.
