In certain species of fish, scale color can either be blue, yellow, or blue and yellow striped. If a blue fish and a blue/yellow striped fish mate, what color scales could their offspring have?

Blue scale or blue/yellow stripe scale

Explanation:

Let us assume that the blue color is represented by B allele while the yellow color is represented by Y allele. The two alleles are equally dominant on one another, hence, BY would represent blue and yellow stripe gene.

Blue scale - BB

Yellow scale - YY

Blue/yellow striped scale - BY

Crossing BB and BY

               BB   x   BY

         BB   BY   BB   BY

Hence, their offspring is either BB (blue scale) or BY (blue/yellow stripe scale).

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

it means there are 3 atoms of oxygen
