Answer:
The statement - When blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows, describes a negative feedback loop.
Explanation:
In the human body, the term homeostasis means the tendency of the various systems in the human body to stay in optimal ranges for health by self regulation through feedback controls. It is very important because it maintains equilibrium and provides stability to the human body. A negative feedback loop (inhibitory loop) is a type of self-regulating system in which increased output from the system inhibits the future production by the system. Example of negative feedback to achieve homeostasis are blood pressure
, body temperature, blood sugar. In blood sugar regulation, the hormone insulin lowers blood glucose when levels are high and the glucagon increases blood glucose when levels are low. In a positive feedback system, the output amplifies the original stimulus. Examples of a positive feedback system are child birth, lactation, blood clotting etc. During child birth, the hormone oxytocin released increases and speeds up the contractions.
Answer:
Explanation:
The plate were supposed to streak by D. radiodurans but unfortunately it was streaked by E.coli.
As there is no other petri plate available, this plate was exposed to the UV for the 30 minutes. The plate was not left uncovered and because of that the total E.coli could not die and another streak of D. radiodurans was done on the same plate.
As a result of incubation there will be growth of both of the organism in the petri dish.
Arteries carry blood away from the heart to the body.
