The vas deferens are a fibromuscular tube which connect to the epididymis, and is an excretory duct of the testis.
Hope I could help! :)
The branch of biology dealing with interactions along organisms and between organisms and their environment is called Ecology, I believe.
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:
derived trait
Explanation:
An ancestral (or primitive) trait/character is a feature inherited from the common ancestor of the species/group of interest, while derived traits are those that were absent in the last common ancestor of the group of interest. For example, considering mammals as the target group, the presence of hair is a shared derived trait relative to other vertebrates, i.e., amphibians, reptiles and birds. However, this trait (hair) is ancestral for humans since the genetically closest species to humans (e.g., chimpanzees), also have hair, and they have inherited this trait from a common ancestor.
