The answer is:
From smallest to largest (within the organism):
Cell, Tissue, Organ, Organ System, Organism.
Explanation:
Groups of similar cells working together for a function are tissues. Similar tissues working together to perform a function make an organ. Similar organs with a common purpose are called an organ system. Multiple organ systems make up the organism.
Below the cellular level, there are organelles, molecules, atoms, and subatomic particles.
Above the organism, there are populations (all of the organisms of a species in an area), communities (all species in an area), ecosystems (the community and environment), and the biosphere (the Earth).
Answer:
Identical Twins
Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy. They share half of their genes, just like any other siblings.
Answer:
it causes the rapid increase in PH which may harmful for the for fishes and other aquatic lives.
Explanation:
There are a lot of materials which are used to neutralize the acidity of soil.some examples of such materials are slacked lime, quick lime, and liquid lime etc. Lime increases the PH and the concentration of calcium which helps in removal of phosphate from water. Raising PH also cause to remove the carbon dioxide from the water. But keep in mind that rapid increase in PH is harmful for the fishes.calcium oxide also causes the rapid increase in Ph therefore, it is not advisable to use in fishpond.
Answer:
The correct answer would be - CDK inhibitors.
Explanation:
Removing the CDK inhibitors in nonproliferating cells can reactivate the cell cycle that can be useful in various cell and tissue repair and also in cell replacement therapies.
These cells are depends on the parent cells that are able to divide so that the daughter cells are limited to the same cell lineage. If CDK inhibitors are removed from the cells can help in proliferating the cells as the cyclin B will be binding to the CDK1 that helps in cell cycle by rising Cyclin B - CDK complex.
Thus, the correct answer is - CDK.
These valves (more generally called the atrioventricular valves) are there to prevent back flow of blood from the ventricles to the atria when the ventricles contract. The same thing happens in both of them:
As the ventricles contract, the pressure in the ventricles increases. This, due to the fact that the valves are one way valves, causes the tricuspid and mitral valves to clamp shut. Then, as the ventricles keep on contracting, and blood is pushed upwards, is it prevented from travelling back into the atria and must travel out of the semilunar valves, through to the aorta and pulmonary artery and out of the hear.
