The organic molecules that functions to help <span>speed up biological chemical reactions would be proteins. These substances are called enzymes which are made up of proteins. Hope this answers the question.</span>
The answer to your question is C- colder , saltier , and denser why because they don't have the same density level and deep ocean water is more dense than surface. and also From
your feet to your knees the water feels icy cold and from your knees to your head the water feels
warm. You probably wondered what causes this to happen. What you felt were warm surface
currents and cold deep currents. Changes in the density set these currents in motion. some ocean currents are set in motion by the wind other ocean currents are created by something you can't feel or see. Differences in density of water can also cause currents to form and move. Density is affected by temperature and salinity. i hoped i helped
Answer:
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.

C.) Scanning electron microscope. You would not be able to see a whole insect with one of these.

Answer:
A. Scientists discovered chromosomes and DNA.
Explanation:
Mendel's ideas were based on patterns of inheritance in plants. Although he identified these patterns, at the time, we did not know what the hereditary material was. This means Mendel couldn't uncover the mechanism of why he was seeing the patterns he was.
When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.
