Answer:
The CORRECT ANSWER IS B.
B. Unlike the other countercurrent systems, a countercurrent multiplier system expends energy in active transport.
Explanation:
The countercurrent multiplier system involving the loop of Henle uses up energy in the form of ATP to actively conduct NaCl out of the filtrate in the upper region of the ascending limb of the loop. This energy in the form of ATP that is being used uniquely differentiates a countercurrent multiplier system from the different forms of countercurrent systems.
Answer:
<u>Answer to Question 1:</u>

Hope that answers the question, have a great day!
Energy from sunlight is being used in an indirect way for walking the dog. Plants photosynthesize in which they absorb energy from sun and convert it into chemical energy, which is stored in organic product formed as a result of photosynthesis. When this organic compound is consumed by us, we use the chemical energy stored in that food to mechanical energy for walking the dog. Hence, the energy to walk the dog comes from sunlight.
I believe it's Lower.
Hope this helps!
Answer:
37oC - temperature
It is important that the temperature is controlled because it maintains consistency and safety.
Explanation:
-Temperature is a common type of controlled variable.
-A control variable is anything that is held constant or limited in a research study
