Can i please get some help with this

A.) Homozygous Dominant

A Homozygous gene is an gene that has 2 of the same alleles.

    In this example, they both have the same allele. (G, G)

When an allele is written in an uppercase form, (G), it is dominant.

A dominant allele is an allele that is more likely to be able to be passed on to the next generation.

In this example, (GG), It is considered to be a Homozygous Dominant

I hope this helps :)

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

more words for this could be abiotic and biotic

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem
