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>
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. They all have the same basic pattern of bones. They inherited this pattern from a common ancestor. However, their forelimbs now have different functions
An example of a biology valentine is "Are you dopamine? Because every time I see you I feel happy".
<h3>What is a biology valentine?</h3>
