4. nucleoid region
Bacterial cell's do not have a nucleus; their DNA is found in this region.
Answer: The cells have differentiated.
Explanation:
The process by which a cell changes from one type to another is called cellular differentiation. When this happens, the cell changes to a more specialized type. So this creates differentiated daughter cells which are important in a multicellular organism because <u>they are able to perform different and specialised functions</u> in an organism.
Answer:
The correct answer is option sebaceous glands.
Explanation:
The dermis layer has two glands sweat and sebaceous glands. Sebaceous glands are associated with skin hair follicles and produce a lipid-rich substance having minerals and proteins.
Sebaceous glands also assist the skin to inhibit or protect from microbial growth due to the presence of some fatty acid and lipids.
Thus, the correct answer is option - sebaceous glands.
Opioid receptors interact with G proteins and arrestin. In consequence, opioid receptors interact with protein biomolecules.
<h3>Proteins and opioid receptors</h3>
Proteins are fundamental biomolecules composed of long chains of building blocks called amino acids linked by peptide bonds.
Proteins may have both structural (e.g., components of the cytoskeleton) and enzymatic functions (in this case, activation of signaling pathways).
Opioid receptors interact outside the cell membrane with opioid drugs (e.g., heroin) and with the G proteins inside the cell.
Opioid receptors also interact inside the cell with a special protein that is known as arrestin, thereby activating specific signaling pathways.
