<span>Compound Microscope
Compound microscope is commonly used in the schools and colleges.
It comes under the category of microscopes used in biology.
It has two lenses namely the objective lens and the ocular lens.
It provides a magnification of 1500X.
Eyepiece lens is of 10X or 15X power.
It is used to observe bacterial, protozoa, various cells, etc.
</span><span>Dissecting Microscope
It is also called stereo microscope.
Its magnification power is less than the other microscope.
It gives a 3 dimensional picture.
Due to the low magnifying power they are used to observe little bigger objects than other microscopes.
They are used in the surgeries, dissection, forensic science etc.</span>
Well, different organisms require different things. A single celled bacteria does not need a lot at all compared to a plant or animal. One cell can support a bacrerium. An animal needs many cells to carry out the functions necessary for it to live.

Answer:
Option C
Explanation:
In elephant seals, the male arrive the beach first and start establishing its territory. Once their territory is established female elephant seals starts arriving at the beach and prefer mating with the male who can defend their territory or females in his territory from other males. All females in the territory of specific male mate with the male give birth to their pups and after staying for few months move back into the water.
hence, option C is correct
False in lunar eclipse the shadow is cast on the sun
Transform boundary – this type of fault is found where two tectonic plates are moving alongside and parallel to each other mostly in opposite directions. This type of fault is also responsible for the rift valley and block mountains. No crust is destroyed nor new crust formed.
Convergent boundary – At this point, two tectonic plates are colliding because they are moving in opposite directions at each other. The pressure and stress of the collision force causes the plates to begin crumpling and folding at the boundary forming features such as fold mountains (an example is the Himalayas).
Convergent boundary – At this boundary , the denser of the two colliding tectonic plates (usually the oceanic plate) is subsided by the less dense one (usually the continental plate). The plate being subsided begins to melt as it does down into the mantle and becomes liquid rock. This magma rises through the fissures formed at the boundary and erupts into volcanic islands along the boundary.
