B is the best answer.
I hope this helps! :)
Answer: (A), (B), (C) and (E)
Explanation:
- Coral reefs are found in the oceans formed by the accumulation of the skeletal remains of the invertebrates. They are found under water.
- Cold seeps refers to those area where the gases such as methane, hydrogen sulfide comes out through the vent, under water.
- Hydrothermal vents are the places where the hot intruding magma reacts with the sea water producing a vent.
- Rocky intertidal zone refers to the zone between a high and a low tidal mark.
Thus under the ocean, the structures such as coral reefs, cold seeps and hydrothermal vents forms where the tide is not so high and not so low.
Kelp forest is the odd one, that refers to those brown colored seaweeds, having high nutrients in salt water.
Answer:
Im not sure but it should be D.
Explanation:
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.
Some of this you have to do on your own
