<h3>Answer;</h3>
C. The less energy the organism requires, the more efficient the energy transfer.
<h3><u>Explanation;</u></h3>
- <em><u>All living organisms need energy in one form or another since energy is required to drive metabolic process in various metabolic pathways, which organisms rely on for survival.</u></em>
- <em><u>Food chains show how energy flows in an ecosystem from the lowest trophic level to the highest level </u></em>and also how efficiently organisms acquire this energy, use it and how much energy remains for use or how much energy is transferred to the next trophic level.
- The less energy an organism requires, the more efficient the energy transfer as more energy is conserved.
Answer:
a. 1/2 b. The organism is an animal
Explanation:
a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?
Medullary index = diameter of medulla/diameter of hair.
Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,
Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2
b. Is this organism human or animal?
Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.
Answer:
I believe the answer is Photosynthesis
Explanation:
<span>Pulmonary vein
Pulmonary circulation is the movement of blood starting from the heart, where deoxygenated, or carbon dioxide-filled, blood leaves from the right ventricle and through the pulmonary valve, then into the left and right pulmonary arteries and arrives at the lungs. During the process of respiration, the carbon dioxide is released and oxygen is added to the blood. </span>
