Answer:
Proteins/fats
Explanation:
Which of the following classes of molecules produces the most energy per gram?
There are four classes of biological molecules: fats, carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram.
Answer:
The answer is D.
Explanation:
It occurs continuously in the cells of all organisms and often involves an exchange of gases. There are 2 types of cells, 1 is Eukaryotic, which holds a nucleus, and the 2nd is Prokaryotic, which do not. Prokaryotes are single-celled organisms.
The type of cell division being shown is meiosis. Meiosis creates four haploid cells. The genetic material is exchanged between the cells during meiosis, meaning that the four daughter cells of each have a different variant of the genetic information.

eukaryote cells DNA is found in the nucleus of the cell, the form the
DNA (e.g. chromosomes vs. chromatin) is in depends on what stage of the
cell cycle you are talking about. In cells that have mitochondria, DNA
is found there as well. Mitochondrial DNA is distinct from nuclear DNA
and doesn't code for the same things. In prokaryotic cells DNA is found
in the cytoplasm. Don't forget that other entities may also contain DNA
such as viruses.
Although DNA is technically confined to the places outlined above, the
reality is cells are dying all the time and spilling their contents
including their DNA. As a result DNA is all over us and everything we
touch, and the same goes for other organisms.
Bacterial cells DON'T typically have a nucleus. They are called
prokaryotic because of that (prokaryotic means "before nucleus" where as
eukaryotic means "true nucleus"). Their DNA is typically in the
cytoplasm usually as a single circular shaped chromosome. The also
sometimes have smaller peices of circular DNA called plasmids that are
also in their cytoplasm which they can exchange with each other.. </span>
Answer:
The bottom one is "evaporation" and the one to the right is "precipitation".
Explanation:
Evaporation is when the sun heats up a body of water and turns the surface water particles into water vapor. The water vapor then goes into the air and turns into clouds. Precipitation is basically rain.
