Water (H2O) takes up more than 60% of the body thus the answer is C
Biodiversity decreases, and the overall health of the ecosystem decreases.
Answer: Option D
<u>Explanation:</u>
In a niche when two different species occupy a niche competition arises between them. In due course both the species fight for existence and nature selects the best adaptable one to win. The other species either reduces in its population or gradually in struggle for existence they deteriorate and die.
Hence a decrease in bio diversity happens here due to natural selection. If the biodiversity is decreased in a particular niche it affects the growth of different species which in turn affect the whole ecosystem resulting in decrease of the overall health in an ecosystem.

Answer:
a. Resolving power (R) = 346.7 nanometers (nm)
b. No, because the resolving power is 346.7 nm
Explanation:
In microscopy, resolution or resolving power (R) refers to the minimum distance at which two distinct points can still be distinguished as separate entities. R can be calculated by the following equation:
Resolving power (R) = wavelength /(NAo + NAc), where NAo is the numerical aperture of the objective and NAc is the numerical aperture of the condenser. In the case above described:
R = 520 nanometers / (1.25 + 0.25) = 346.7 nanometers (nm)
In consequence, the resolving power of this microscope at 520 nanometers of wavelength is 346.7 nm, thereby two points separated by 300 nm will be too close to be distinguished as separated objects.
