Answer:
dna
Explanation:
dna has all the information in it to form a new cell and new organ
Answer:
b. by increasing the heart rate
c. by increasing the respiratory rate
Explanation:
Increased activity of skeletal muscles would require an increased supply of oxygen to these cells to sustain the muscle contraction. Muscle cells perform aerobic cellular respiration in the presence of oxygen and produce ATP molecules to be used during muscle contraction. Therefore, there is an increase in heart rate to pump sufficient blood to the skeletal muscles which in turn ensures enough supply of oxygen. Also, there will be an increase in the respiration rate to inhale the required oxygen.
I thing B is the right answer
During the stress, heart rate, respiration rate and temperature increase. The reason for that is the influence of sympathetic nervous system, which starts t<span>he “fight or flight” system. As a result of this adrenaline (epinephrine) is released from adrenal glands. Adrenaline circulates through the body and brings a lot of physiological changes. The heart beats faster than normal, pushing blood to the muscles, heart, and other vital organs and as a consequence, the person undergoing these changes also starts to breathe more rapidly to deliver more oxygen to organs. Meanwhile, adrenaline triggers the release of glucose and fats from energy storages. These molecules flood into the bloodstream, supplying energy to all parts of the body.<span> The temperature is rising due to increased metabolism.</span></span>
