Answer:
use own words
Explanation:
In competitive inhibition, an inhibitor molecule is similar enough to a substrate that it can bind to the enzyme's active site to stop it from binding to the substrate. ... In noncompetitive inhibition, an inhibitor molecule binds to the enzyme at a location other than the active site (an allosteric site)
hat is the difference between competitive and non competitive inhibition?
The main difference is that in competitive inhibition, the inhibitor binds directly to the active site of the enzyme. ... Competitive inhibition can be overcome by increasing the concentration of the substrate. This cannot occur with non-competitive inhibition.

Answer:
Increased genetic variation reduces the species chances of being extinct. Conversely, reduced genetic variation in a species increase the chances of the species being extinct.
Explanation:
With increased genetic variation in a species, there is increased phenotypic variation amongst organisms in the species for natural selection to act on with selection pressures exerted upon the species in their environment e.g. predation or diseases. Hence even if a certain genotype express susceptibility to a certain disease, only some organisms will be selected against and there are sufficient organism without this genotype that will be able to survive and ensure the continuity of the species.
Conversely, if all the organisms express the same genotype susceptible to the disease (in extreme cases), upon exposure to the disease (which acts as the selection pressure), all the organisms will die and there will be no surviving organisms for the continuity of the species. Hence with minimal genetic variation, the species is more prone to extinction due to the inability to withstand selection pressures.
This is often a common cause of concern in the conservation of endangered species. Due to the small number of e.g. tigers remaining, most offsprings are produced through inbreeding between family members thus even though the family tree of the species is expanding, there is little genetic variation within the species. Therefore, the chances of extinction of these endangered species is high and thus biologists and conservationists have to monitor the selection pressures exerted upon these species by their environment to reduce the risk of extinction.
Answer:
A: The xylem releases all it's water
Explanation:
This is so because wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant.
