Answer:
100 units
Explanation:
The interphase of the cell cycle includes three stages: G1, S, and G2. During the S phase of interphase, the cell enters the process of DNA replication. DNA replication duplicates the existing DNA molecule and doubles the DNA content of the cell. The cell accommodates the newly formed DNA in two sister chromatids of chromosomes. If a cell of grasshopper contained 200 units of DNA in the G2 phase, the cell would have 100 units of DNA in the G1 phase. The S phase would have doubled the DNA content and the G2 phase had 200 units.
<span>The movement of fluids between cellular compartments is regulated by osmotic and hydrostatic forces.</span>
<span>
Hydrostatic pressure<span> is the force exerted by a fluid against a wall which causes movement of fluid between compartments. This pressure is important for exchanging plasma and nutrients between capillaries and surrounding tissues</span> and also in the nephrons (kidneys) where ensures proper filtering of the blood to form urine.</span> <span>Fluid also moves between compartments along an osmotic gradient (the difference in concentration of solutes on one side of the cell membrane to that on the other side). Water constantly moves into and out of fluid compartments via osmotic gradient.</span>
Answer:
d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.
Explanation:
Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.
Their active sites are primary protein 3D structure for binding with substrates during reactions.
Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,
This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites occupied, therefore denying the inhibitor methylalchol chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites
Answer:
Photosynthesis is not taking place and carbon dioxide is not being processed.
Explanation:
The process by which plants make glucose (carbohydrates = energy stores) from carbon dioxide and water is called photosynthesis and uses sunlight energy. A by-product of photosynthesis is oxygen.So plants use water and sunlight to grow and they produce oxygen. Animals on the other hand eat plants, use oxygen and breathe out carbon dioxide.
Since the space station is in the shadow of the earth, the plants are unable to complete the process of photosynthesis and the carbon dioxide that is being produced by the humans cannot be utilized by the plants due to no sunlight. There for the carbon dioxide is going to continue to build up as the energy storage molecules are being depleted and not replenished.
The heart and the arteries of a person, both contracts to pump the blood throughout the body. The aorta, which is the largest artery of the human body, pumps the blood from the heart to the entire body of a person. The oxygen-rich blood is pumped out of the left ventricle when its contraction into the aorta, from where it is transported to the whole body.
Hence, the given statement is true.
