Answer:
1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.
2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
Explanation:
The superficial palmar arch<span> is formed predominantly by the </span>ulnar artery<span>, with a contribution from the </span>superficial palmar branch of the radial artery<span>. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the </span>princeps pollicis artery<span>, the </span>radialis indicis artery<span>, or the </span>median artery<span>, the former two of which are branches from the radial artery.</span>
The best way to deal with biodiversity hotspots is to focus on a limited area which would save the greatest number of species.
Answer: floods, forest fires, earthquakes
Explanation:
The short term changes are those changes that affects the organisms immediately. The effect of these changes remain for short duration. Thus the environment and the living beings adapt the changes. A flood can wipe out the terrestrial ecosystem, the ecosystem will regain its original form when the water level depletes. Forest fires may kill several trees and animals in an ecosystem. But some plants and animals will sustain which can give birth to new colonies. The earthquakes affect the earth crust and biosphere. The earth crust may get stabilize again by filling up the crater and biosphere will also promote of living beings.
This electron transport chain of photosystem II helps the chlorophyll molecules in the plant leaves to tap the energy in the light photons. This energy is used to split a water molecule into hydrogen and oxygen atoms. The hydrogen is used to reduced carbon dioxide to make carbohydrates. Therefore, Atrazine stops photosynthesis by inhibiting the capacity of the plant to harness energy from sunlight for photosynthesis.
