They are said to be Homozygous

reason: Organisms that have two identical alleles for a particular trait are said to be homozygous (AA) or (aa). 6. Organisms that have two different alleles for the same trait are heterozygous (Aa).

Answer:

Homozygous

Explanation:

The obvious traits in living organisms are usually controlled by molecular structures called GENES. A gene exists in two contrasting forms called ALLELES. Based on this, there are two different alleles for two different traits in a gene.

An organism that contains the same/identical alleles for a particular trait is said to be genotypically HOMOZYGOUS while an organism that possesses two different alleles for a particular trait is said to be HETEROZYGOUS.

For example, height trait controlled by a single gene that possesses two alleles: T for tallness and t for shortness. An organism that has two identical alleles e.g TT and tt is said to be homozygous for that trait while an organism that possesses Tt is heterozygous.

when educating students about the differences between brown fat versus white fat, the instructor will share that brown fat has i

Verdich [7]

The brown fat has iron in its mitochondria that will facilitate production of a protein that releases the energy generated from metabolism as heat.

Your body produces the hormone norepinephrine when it becomes cold. Norepinephrine receptors are present in brown fat. These receptors alert the many mitochondria to begin producing energy when they detect the hormone. You will feel warm as a result, which will aid in regulating your body temperature. It basically produces proteins that releases the energy generated from metabolism as heat.

Brown fat converts fat molecules and blood sugar (glucose) into heat and contributes to the regulation of body temperature. Brown fat is activated by cold temperatures, which causes a number of metabolic changes in the body. But the majority of our fat is white fat, which can store extra energy. In obesity, too much white fat accumulates.
