Answer:
It has long been known that static pressure affects middle-ear function and conventional tympanometry uses variations in static pressure for clinical assessment of the middle ear. Middle-ear under-pressures tend to reduce the velocity magnitude more than do middle-ear over pressures.
The effect of middle-ear static pressure on the acoustic response of both structures is similar in that non-zero middle-ear static pressures generally reduce the velocity magnitude of the two membrane components in response to sound stimuli.
A because it’s dna fragments
Answer:
The correct answer is convergent evolution.
Explanation:
The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.
They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.
Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.
The name comes from a latin word meaning to glue or bind together. DNA ligase catalyses the joining of DNA fragments (usually those produced by restriction enzymes). Thus different genes can be put into vectors and moved into other hosts.
Answer:Medulla and pons.
Explanation: Brain is the part of the body that controls all body activities. Medulla and pins are part of the brain.
Medulla controls respiration. It receives signals from chemoreceptors and send to muscles that allow respiration. It also regulate heart rate and blood pressure to ensure adequate blood supply circulate the body system.
Medulla also help in adjusting respiration when there is need and also generates normal breathing movements by stimulating the nerve that supplies the diaphragm. This pons are located under the medulla and it controls speed of involuntary respiration( respiration
Not under conscious control).
When a patience shows a disorder in respiration, invountary respiration, increase in heart rate its a disorder of Medulla and pons also called Brainstems
