The lymphatic mass found low in the throat overlying the heart is the

thymus gland.

tonsils.

uvula.

spleen.

Correct A). Thymus gland

The thymus is a lymphatic mass that is found in the lower part of the throat overlying the heart. It plays an important role in the development of a healthy immune system.

Hence, the correct answer would be option A.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

hope this : )

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
