I think it's c: Quantity A is weight & Quantity B is mass
Chlorophyll is found in the <span>chloroplasts :)</span>
Answer:
I can't see the image could you please type it out?
Explanation:
The answer is <span>B. A smaller cell has more surface area than volume.
</span>This is simple mathematics. Let's imagine that cell is spherical.
Now, we have two spheres: one big (with radius r = 5 cm) and one small (with radius r = 2 cm).
The formula for the surface area of the sphere (A) is A = 4 π r².
The formula for the volume of the square is 4/3 π r³.
Now, let's compare two spheres:
Small sphere: Big sphere:
r = 2 cm r = 5 cm
A = 4 π 2² = 50.3 cm² A = 4 π 5² = 314.2 cm²<span>
V = 4/3 </span>π 2³ = 33.5 cm³ V = 4/3 π 5 ³ = <span>523.6 cm³
According to the calculation, the smaller sphere will have more surface area than volume. This can be extrapolated to all shapes, not only spheres, so the </span><span>smaller cell has more surface area than volume.</span>
Correct answer: D). Energy decreases from bottom to top because some is used at each level for life processes.
The pyramid of matter and energy in the ecosystem tells that when energy flows from one trophic level to another trophic level, then some amount of energy is always lost as a heat, which is lost to the atmosphere and it never comes back.
Therefore the primary consumers obtain 10% of energy from the autotrophs and secondary consumers get 1% of energy and that of tertiary consumers get 0.1%. It shows that top consumers receive the least energy. It is also called as10% law.
