Answer:
An electrochemical Gradient
Explanation:
During the translation of mRNA to protein, the nascent polypeptide chain that is formed is not yet a functional protein right after translation. The polypeptide must then undergo another series of processing and packaging and may even need another protein(s) to completely form a functional moiety. Generally, for this a mix of chaperones may be needed to complete the protein synthesis pathway.
The answer to this is B. Topaz
Microfilaments
Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis.
Microtubules
Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of "tracks" for cell organelles and vesicles to move on. Microtubules also form the spindle fibers for separating chromosomes during mitosis. When arranged in geometric patterns inside flagella and cilia, they are used for locomotion.

A. A steep slope has a higher rate of soil erosion than a rate of soil formation.
Answer:
G, S, G2, M
Explanation:
Cell cycle refers to the orderly events that prepare the cells for cell division and finally divide the parent cells into the daughter cells. The cell cycle consists of two stages: interphase and M phase.
Interphase is the phase wherein cells prepare to enter the M phase. Interphase has three stages: G1, S, and G2.
G1 is the first gap between represents the time between the end of mitosis and the beginning of the S phase. During the G1 phase, normal growth and metabolism take place. G1 phase is followed by the S phase, the synthesis phase, during which DNA replication and synthesis of histone proteins occur.
The cells then enter the G2 or the second gap during which cells synthesize more proteins and prepare to enter the M phase.
M phase is the phase of nuclear division that divides the nucleus of the parent cell into 2 or 4 daughter nuclei (depending on the type of the cell division that the parent cell has entered).
Therefore, the sequence of the stages that the cell will go through is G, S, G2, and M.
