That is why people of Taiwan should decide on their own whether they would like to live an independent country or to remain the part of China.
Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
The architecture of a kelp forest depends on its physical structure, which influences the species that occupy the forests. Kelp forests usually include three types of kelp and two types of algae:
1. Prostrate kelps lie near and along the sea floor and form the lowest level of kelps
2. Stipitate kelps are above the prostrate kelps upto a few meters above the seafloor.
3. The Canopy kelps include the largest species of kelp and often extends to the top of the ocean surface.
4. Coralline algae directly and often extensively cover geologic substrate i.e the sea floor.
5. The benthic assemblage is composed of other algal species.
