A mutation is a new element added to the genetic buildup of an organism. this leads to new abilities that makes that organism adapt to different things, this is passed down through the organisms descendants which will help them get through situations other organisms can't, thus helping the entire species evolve.
Answer:
recognizes a hormone’s chemical structure
Explanation:
In living systems, chemical messengers called hormones are secreted into the body via the bloodstream or ducts by certain glands called endocrine glands e.g pancreas, hypothalamus etc. These hormones are meant to effect a physiological change in certain cells called TARGET CELLS.
In biology, a target cell is any receiving cell that has the ability to respond to signals and messengers like hormones. This responding ability of hormones is due to the possession of specific receptor sites for the specific hormones. The receptor on a particular target cell recognizes that specific hormone's chemical structure, hence, will only respond to it.
For example, an insulin hormone secreted by the pancreas will only be responded to by a target cell that recognizes the chemical structure of the insulin protein using its receptor molecule.
An animals niche is its functional role in its ecosystem
Answer: Everything that is mutations
Explanation:
Before administering a cephalosporin to a patient, it is most important for the nurse to assess the patient for an allergy history to penicillin. The drug cephalosporins belong to the group of beta-lactam antibiotics which has a similar structure and as well as action to that of penicillin. If a patient has allergy reaction of penicillin, then surely the patient would not be able to take in cephalosporins. This antibiotic is produced from the fungus Acremonium. It is being used to treat infections that are caused by bacteria which is susceptible to this type of antibiotic. The first generation of this antibiotic was made to kill gram-positive bacteria and it was further developed for it to have increased activity to gram negative bacteria.
