Answer:
Oxygen is moved around the body of an echinoderm in its C. water vascular system.
In photosynthetic organisms, NADPH is produced by ferredoxin-NADP+ reductase in the last step of the electron chain of the light reactions of photosynthesis. It is used as reducing power for the biosynthetic reactions in the Calvin cycle to assimilate carbon dioxide.
Answer:
Structure of large intestine: Large intestine is the part of digestive system which comes in the end. It consist of four parts. Large intestine length is 150 cm and width is 5 cm.
Function of large intestine: It performs two main functions.
1) Large intestine helps in the absorption of water and nutrients from the food which cannot be digested in the stomach.
2) It removes the waste material from the body in the form of feces.
<span> Sexual reproduction is more likely to increase genetic diversity because every offspring has twice as much genetic material to pull from when being formed compared to the one set of genes in asexual reproduction. There is also the differences between mates that can increase genetic diversity as well if many different mates are mated with.
Asexual reproduction typically happens more quickly, however, because an asexually reproducing organism does not have to bother with finding a mate, courting and allowing time for the genetic material assimilate, they can just reproduce and all of their genes are utilized in the new organism rather than just half.
The whiptail lizard may reproduce either sexually or asexually depending on the environmental conditions.</span>
Small, but normal variations in genes may produce proteins that work differently from those of other individuals ( friends or relatives). This may affect how we respond to different medicines. The extent to which these proteins functions varies from one individual to another. Example; certain painkillers only work when body proteins convert them from an inactive form to an active one. If these proteins work too fast, the drug will be eliminated from the body before it has time to work. To do their job the pain killers need to bind and modulate a target body protein, the receptor, such that if the target body protein is altered the pain killer might not be able to bind.
