Many fishes excrete Ammonia which takes a lot of water to be removed !! All the excess water are excreted out either through excretory system or by gills !!

Second they maintain ion balance by gills by uptaking ions by active transport !

Answer:

Explanation:

I think No. because matter can neither be created nor destroyed...chemical change cannot alter the number of atoms in a given reaction. The atoms can only rearrange so that it can yield a new molecule/compound but the number of atoms should stay the same.

The Punnett square shown presents a cross between two piranhas. Both parents have large teeth.

Llana [10]

Answer:

The correct answer would be C) 75% large-toothed and 25% small-toothed.

It can be explained with the help of the law of dominance which states that the dominant allele expresses itself completely over the recessive allele in the heterozygous condition.

So, the genotype TT, as well as Tt, will result in the production of dominant trait or character in the offspring.

Thus, three (1 TT and 2 Tt) out of four offspring would have large teeth and only one offspring (tt) would have small teeth.

Hence, we can conclude that 75% of the offspring will have large teeth and only 25% will have small teeth.

This can happen because you have recessive and dominant characteristics passed down. So you can get a totally different chromosome that doesn't come from your parents because your grandparents may have had it or great grand parents, the line keeps going .
