<span>Without variation, there is no difference between members of a population to be "selected for" in the first place. This is a basic tenet of natural selection. A new trait must arise in order to advance or decrease the fitness of the individual, and hence, its ability to pass on its genes.</span>

Which statement must be true about the organism?
Artyom0805 [142]

Answer:

If we're talking about human organism then

It is multicelular.

It has a backbone.

It contains cells without nuclei.

Explanation:

human as almost all animals in the world is multicellular meaning they have more than one cell (some bacterias has only one)

backbone or "vertebra" is the is the bone of our back who supports us making us stand up.

Yes our cells contain nuclei , The nucleus contains nucleoplasm, a component where it is immersed in genetic material and as structures that are important for the performance of its functions

And finally our body don't have radial symmetry, radial symmetry is when you can "cut" the image in more than one piece keeping the symmetry in every side, some animals with radial symmetry are the starfish and the jellyfish.

After having read, how do you think pollution in one sphere can have an impact on another? Be specific and explain.
Orlov [11]

Answer:

Pollution can impact other spheres

Explanation:

Okay here ya go :)

As more and more pollution occurs it can cause the ozone layer to slowly start to decay in a way as the sphere get thinner. What this impacts is the troposphere. Since the ozone layer starts to fade away it can't filter out as much harsh rays from the sun. Those rays eventually get to the earth's surface and bounces off the surface warming up the earth causing life to be affected in the troposphere by warming up the earth.
