Answer:
<h2>Normal quiet expirarion of air is known as Tidal volume which is equal to 500 mL .</h2>
Explanation:
Normal quiet expiration or Tidal volume is a expiration of air with each normal breath . This is about 500 mL . It is composed of about 350 mL of alveolar volume and about 150 mL of dead space volume . The alveolar volume consist of the air that reaches the respiratory surface of alveoli and involve in gaseous exchange . The dead space volume consist of air that does not reach the respiratory surfaces . The lowest value is of Tidal volume . There is an extra amount of air that can be expired forcibly after a normal expiration i.e., known as expiratory reserve volume which is equal 1000 mL of air .
A firefighter wakes up in the middle of the night to the sound of an alarm. it is likely that her adrenal glands have released epinephrine and norepinephrine.
The medulla of the adrenal glands secrete the hormone epinephrine, which is also known as adrenaline. Epinephrine is released into the bloodstreams when a person experiences strong fight or flight emotions. This leads to an increase in the rate of the heart beat, muscle contraction and movement.
Answer:
each new DNA double helix consists of one old DNA strand and one new DNA strand
Explanation:
DNA replication is a semi-conservative process which means a new DNA duplex contains one old DNA strand and one new DNA strand because each DNA strand act as a template strand over which a complementary new DNA strand is made.
So after the completion of DNA replication, each new DNA double helix consists of an old strand of DNA and a new DNA strand. After the replication, only one strand is used for transcription. In RNA formation uracil comes in place of thymine.
The cell would eventually shrink causing the plant to wilt.
Answer:
The correct answer is a an amino group and a carboxyl group.
Explanation:
Alanine and serine are both amino acids.Alanine is a simple amino acids where serine is a hydroxyl amino acids.
When alanine and serine molecules combine to form a single molecule at that time an amino group and the carboxyl group will be joined together to form a ala-ser peptide linkage.
