Answer:
C. It is active transport, and moves against the concentration gradient.
Explanation: Pinocytosis is an active transport in which the molecules move from a low to a more higher concentration gradient. During this process it requires energy to move molecules and the energy used is ATP.
The answer is C. thousands of galaxies
because<span> Hubble found 10,000 of galaxies just by observing one small little area in space.
So, it has to be thousands.</span>
Answer:
The functional groups that define the two different ends of a single strand of nucleic acids are:
B. a free hydroxyl group on the 5' carbon a free hydroxyl group on the 3' carbon
G. a free phosphate group on the 5' carbon
Explanation:
A nucleic acid is a polymer formed of nucleotides that are linked with a phosphodiester bond. The structure of a nucleotide consists on a phosphate group linked to a pentose (ribose in RNA and deoxyribose in DNA) that is also attached to a nitrogenous base. The nitrogenous bases are adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA).
DNA and RNA are nucleic acids which can be found in a double or single strand presentation.
Nucleic acids are synthesize in the 5’ to 3’ direction, so that is why the convention is that the sequences are written and read in that direction.
The strand of a nucleic acid is directional with an end-to-end orientation, where the 5’ end has a free hydroxyl or phosphate group on the 5' carbon of the terminal pentose, and the 3’ end has a free hydroxyl group on the 3’ carbon on the terminal pentose (ribose/ deoxyribose).

<span>Of these choices, neuronal communication between the brain and the muscles of the leg is best conceptualized as electrical and chemical signaling.
The brain sends signals of the electrical and chemical type to reach the leg and move its muscles. Once these signals get to the muscles of the leg, they are moved into motion as a result of the brain "ordering" the leg to move so that a person could get up or get to another place.
