In the 1950s, the discovery of molecular structure of DNA revolutionized biotechnology.
Hope this helps chu

Answer:
A
Explanation:
Doppler Echocardiogram
A traditional echocardiogram uses sound waves to produce images of the heart. In this procedure, a radiologist uses a transducer to transmit and receive ultrasound waves, which are reflected when they reach the edge of two structures with different densities. The image produced by an echocardiogram shows the edges of heart structures, but it cannot measure the speed of blood flowing through the heart. Doppler techniques must be incorporated to provide this additional information. In a Doppler echocardiogram, sound waves of a certain frequency are transmitted into the heart. The sound waves bounce off blood cells moving through the heart and blood vessels. The movement of these cells, either toward or away from the transmitted waves, results in a frequency shift that can be measured. This helps cardiologists determine the speed and direction of blood flow in the heart.
<span>One reason this might be has to do
with the way your brain processes odors and memories. Smells get routed
through your olfactory bulb, which the smell-analyzing region in your
brain. It’s closely connected to your amygdala and hippocampus, brain
regions that handle memory and emotion. </span>
I don’t know if I understand this myself, but I know that the dependent variable would be the Mitochondria thing, but I don’t know what the operational definition is. Anyway, I’m only in 7th grade, I’ll research this stuff.
a. the starting cell is 2n. how many chromosomes does it have?
b. hom many chromosomes will it have after Meiosis 1?
c. how many chromosomes will it have after Meiosis 2?
