answer of the question: B
Answer:
c. Carbon Dioxide
Explanation:
The rate of respiration is determined by the presence of concentration of carbondioxide gas in the blood because in the process of respiration, energy in the form of adenine tri phosphate (ATP) and carbondioxide gas are produced. This ATP is required for performing different activities while carbondioxide gas is a waste product which must be removed from the blood through breathing. If carbondioxide gas is produced quickly so the rate of respiration is also increased in order to remove the gas from the blood.
Answer: E- The right ventricle.
Explanation: Deoxygenated blood with carbon dioxide and metabolic products collected from the tissues by the capillaries returns to the heart via the venous system and enters the right atrium of the heart. It is then pumped to the right ventricle, then transported to the lungs via the pulmonary artery for gaseous exchange, where oxygen is collected and carbon dioxide is dropped off.
The link where the action
potential of the nerve that meets muscle and causes it to contraction is where excitation-contraction coupling occurs. The T_tubules the
invaginate into the sarcolemma of the muscle cells are the ones that carry the excitation into the muscles. Its depolarization
causes the lateral sacs of the sarcoplasmic reticulum to release ca2+
ions. The ca2+ then bind into their site on troponin and causes the tropomyosin to shift and allow actin to expose
the binding site in which myosin head
will bind and form a cross bridge that is
important in the contraction of the muscle.
Nitrogen is a growth-limiting nutrient because cells need it to manufacture : Proteins and nucleotides
Growth-limiting nutrient is very essential since bio process design criteria in pure culture is mainly centered around it
