Orlov [11]
Hello!

So, day and night are caused because the earth makes a full rotation on its axis once every 24 hours.

That way, have of Earth is facing the sun (it is morning on that side) and the other half isn't (which is why it is nighttime over there).

For example, if it's nighttime in Canada and America, it's morning in Pakistan and India. This is because Pakistan and India are facing the sun whilst Canada and America are not.

A N S W E R:

The balls should be moved so that half the Earth is facing the sun and the other half is not. This would be 24 hours. As for the sun, it is a gas, not a solid, so it doesn't rotate like one. However, that does not mean that it is not rotating to some extent.

Why can't prokaryotic species be defined as a group of similar organisms that could sexually reproduce together?
s344n2d4d5 [400]

Answer:

The prokaryote divides by asexual mode of reproduction.

Explanation:

The concept of species which defines a species as a group of individuals of a population which can interbred and produce a fertile progeny is applicable to the organism which can reproduce sexually.

Since the bacteria divide through asexual means and not through sexual ways therefore the concept of defining a species becomes complicated and does not apply.However the concept of species in prokaryotes is still a topic of research.  

Thus, the biological concept of species is not applicable to prokaryotes.
