1. The deer population might decrease one year because of the increase of numbers in the deers predators such as wolves or because of too many deer that that area doesn’t have enough supplements such as food
2. The deer population could increase because of the decrease in its predators like wolves dying or finding another reliable food source
Anti-bodies. This is not a hard question to answer, as you can just copy/paste the question into a search engine to get an adequate answer.
Answer:
Detergents are amphilic in nature having hydrophilic head (Polar) and hydrophobic long tail (non-polar). The nonpolar hydrophobic tail is mostly made up of of carbon atoms bonded to other carbon atoms.
Tail plays a very important function of detergent by break down the surface tension that exists between grease and water. The tail is required to be non-polar because it attaches to fat (grease) or dirt and repels water molecules and form micelle, which get rinse of with detergent. The non-polar end then move towards the surface and weakens the hydrogen bonds in water, which breaks the break in the surface tension of the water.
Hence, tail of detergent is required to be nonpolar to function by break down the surface tension that exists between grease and water and do the proper cleansing of clothes.
<h2>Cell Cycle
</h2>
Explanation:
Eukaryotes grow and divide by cell cycle.
The main parts of a cell cycle are an ordered series of events – Gap 1 or G1 phase, Synthesis or S phase, Gap 2 or G2 phase, and the mitosis or M phases.
Interphase period (G1, S, G2 phases) - cell grows by size, duplicates its content, replicates its DNA, and finally prepares for mitotic cell division
.
Mitosis and cytokinesis - formation of two identical daughter cells
Cell cycle is regulated by regulatory or restrictive checkpoints in the cell cycle which are activated with detection of a defective DNA.
Proliferation of undesired or cells with defective DNA like in case of tumor cells is controlled by the action of suppressing agents like p53 and cyclins.
The tumor suppressor gene protein p53 prohibits division of tumor cells. Cyclins regulate cell cycle by activation of the enzyme cyclin-dependent kinase.
