The physical manifestation of a gene (such as eye color) varies, depending on the organism's
a. species.
b. germ cells.
c. alleles.
d. lysosomes. user: what type of radiological procedure would be used to evaluate the movement of body organs?
a. ultrasound
b. mri
c. film survey
d. fluoroscopy

Q1. The answer is c. alleles.
An allele is one of two or more alternative forms of a gene. So, if someone has alleles responsible for blue eyes, he will have blue eyes.
Lysosomes are organelles which role is to break down different kind of molecules on the inside. Species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group and produce fertile offspring. And germ cells are cells that give rise to the gametes


Q2. The answer is d. fluoroscopy.
Fluoroscopy is a radiological procedure used to obtain real-time movement of body organs. 
MRI (Magnetic Resonance Imaging) is used to obtain the images of  anatomical and physiological processes. Ultrasound is used to obtain the images of the inside of the body using waves.
