Answer:

The correct answer would be option D.

Explanation:

Large natural reservoirs or source of water below the surface of the Earth is known as the aquifer. The aquifers have become badly polluted because of several reasons, especially human-caused water pollution. But there are few natural processes too that pollute it and make it very unsafe.

Some rocks have toxic metals like mercury and arsenic in them. If such toxic metals get dissolved in water they will make water toxic and lethal.

Thus, the correct answer would be option D.

fgiga [73]

Answer:

To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:

        b        b

B   Bb         Bb

b   bb         bb

The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.

there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.

What is the evolutionary evidence that endosymbiosis is real?
fredd [130]

Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria's genome, but much smaller.
