Answer:
Cell membrane is a semi-permeable membrane that surrounds the cytoplasm.
Explanation:
Archea contains only 1 cell and they are prokaryotic organisms. They have a different molecular setting, thus making them different from bacteria.
Cell membrane of Archea:
- In archeal cell membrane, isoprene chains are connected to glycerol lipid monolayer,
- The cell membrane is either lipid bi layer or lipid mono layer.
- Archeal cell wall contains pseudo peptidoglycan.
Cell Membrane of Bacteria:
- In bacteria, the fatty acid chains are linked to glycerol.
- The cell membrane is a lipid bilayer.
- Bacterial wall contains peptidoglycans.
Increasing extracellular K+ increases the positive charge outside the cell, making the inside of the cell (membrane potential) more negative. This inhibits net diffusion of Na+ into or out of the cell.
Answer:
Gastrulation.
Explanation:
The embryonic development occurs through the different developmental stages like cleavage, morula, blastula and so on. The formation of the germ layers occur in the gastrulation period.
The primitive streak is the structure that develops during the early stages of the gastrulation. As the embryo becomes asymmetric., the cells moves from their initial position and leads to the formation of primitive streak in the gastrulation phase.
Thus, the correct answer is option (C).
The diagnosis is knowledge deficit.
Deficient Knowledge (Parent): Potential Side Effects of Vaccines, related to lack of correct information.
Answer:
The chyme, which is already a fecal bolus formed produces an involuntary stimulus reaching the colon that cause the defecation; The first step is the relaxation of the internal sphincter through the sacral nerve (involuntary), and then voluntarily the cerebral cortex through the pudendal nerves that relax the external sphincter.
