Answer:
The correct answer is option c. "The gametes must be kept wet to avoid desiccation".
Explanation:
External fertilization is an adaption were species reproduce sexually, but there is no direct contact between the female and the male species, because the egg is fertilized outside the female's body. This adaptation occurs more often in aquatic animals because the gametes must be kept wet to avoid desiccation and allow fertilization, which occurs much more easily on aquatic environments.
Answer:
In case, when an allosteric site undergoes certain modifications it will demonstrate some changes like change in affinity towards the inhibitor, however, how the changes take place is not known exactly because of less knowledge of the FX11 composition. Though it is for sure that the modification will decline the affinity and the FX11 will exhibit less efficacy in preventing the growth of C. parvum.
An inhibitor targets the allosteric site as the size and the functional groups present within the site matches with that of the inhibitor, and thus affinity is attained. However, when there is a change in structure, the affinity will also get influenced.
The gossypol and FX11 can be utilized as drugs for human beings as these substances prevent the process of lactic fermentation, and the pathway for lactic fermentation generally is less common in human cells. The parasite C. parvum is found within the digestive tract, and the process of anaerobic respiration usually does not take place in the organs present in the digestive tract. However, in specific cases, only the muscle tissue can go through anaerobic respiration like in the case of performing physical activity. It is also to be noted that the drug can even invade other tissues via blood, therefore, at the time of consuming drugs, there is a need to instruct the patients to prevent any kind of physical activity.
Answer:
Three main pieces of evidence for the Big Bang theory are the red-shift of light, cosmic background radiation and types of elements.
they all evolved from the same species but they had adapted to gather food on their given island. the adaptation was in their beaks
