Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
Epithelium is the thin tissue forming the outer layer of a body's surface and lining the alimentary canal and other hollow structures.
Answer;
Glucose
The nutrient that can be used to produce energy in the absence of oxygen is glucose.
Explanation;
Production of energy without using glucose is called anaerobic respiration. During this type of respiration less energy is released than the case of aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt, which is the amount of oxygen needed to break lactic acid to carbon dioxide and water.
I’m not sure if this helps much, but try thinking of an Aloe Vera plant. When you cut into it, you expose the the sticky center. The part you cut has a “sticky end.” So, think of a knife as the restriction enzyme, and the plant as the DNA molecule that you’re cutting. Hope this helps.
Answer:
B) Changes in the temperature and salinity of water.
Explanation:
<em>Options</em>:
A) Migration of bottom feeders into the region.
<u>B) Changes in the temperature and salinity of water. </u>
C) Migration of fresh water fish to places near the mouths of rivers.
D) Formation of breeding grounds for various species in the shallow waters.
Sea level changes are among the most relevant issues that our planet is facing due to climate change. This phenomenon impacts the salinity and temperature of the ocean because of the melting of glaciers, and ice sheets. Therefore, <u>melting ice alters the level of salinity of the water which, along with temperature, also effect the density of the ocean water, altering ocean currents and productivity.</u> These impacts alter the distribution, behavior, and ecology of marine organisms.
<em>*Note: The melting of the glaciers and ice sheets - result of anthropogenic climate change - has increased sea level.</em>
