It shows that flow of energy in the ecosystem is "Uni-directional" means energy flows only in one direction never reverse
Hope this helps!
Based on the nature of proton gradient, (A) is false, but (R) is true.
<h3>What is a proton gradient?</h3>
A proton gradient is a gradient that exists due to difference in proton concentration between the inner and outer mitochondrial matrix.
An assertion is a statement or claim stating a given position.
- Assertion (A): A proton gradient cannot be established in the mitochondria.
- Reason (R): Hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria.
The assertion, A, is false because a proton gradient is established in the mitochondria due to the function of the proton pump which pumps out protons from the inner mitochondrial matrix to the outer membrane.
The reason, R is true as hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria by the proton pump.
Therefore, (A) is false, but (R) is true.

The correct answer is the 3rd option
Answer:
9 servings
Explanation:
First, let's convert 6 oz to pounds so that the units are the same. There are 16 oz in 1 pound, so 16*6 oz = 96 pounds. There are 9 units of 10 in 96, so our answer is 9.
Flagella provide motility to a sperm cell, cilia act as sensory "antennae" in many cells and microvilli Increase a cell surface area
<h3>What is flagella, cilia and microvilli?</h3>
Flagella is a hair-like structure used by cells for locomotion or movement. The sperm makes use of flagella for locomotion.
Cilia is a hair-like structure that is found on the surface of organisms which are sensitive to touch.
Microvilli is a hair-like structure that is richly fortified with blood vessels found in areas for absorption. This is because it increases the surface area.
