<span>The correct option is B. Eukaryotic cells are developed cells with well defined structures. The organelles inside the cell are well compartmentalized, surrounded with their own membranes. These membranes make it possible for the organelles to regulates the movement of particles in and out of the cell.</span><span />
High temperature and high confining pressure
Answer:
Pepsinogen is produced by chief cells and is activated by hydrochloric acid secreted by parietal cells.
Explanation:
Pepsinogen is a proenzyme produced in the chief cells (that are located in the stomach lining) that, when gets activated, is transformed into pepsin - a peptidase with the function to degrade proteins into amino acids.
The reason why pepsinogen is released inactive is that it would break down all of the cell's proteins because of its proteolytic nature. For this reason, it is released as a proenzyme and gets activated when reaches the acidic environment provided by the hydrochloric acid secreted by the parietal cells, also in the stomach lining.
Answer:
Cellular energy
Explanation:
Osmosis is the movement of water from a less concentrated to more concentrated solution across a semi-permeable membrane. Cellular energy is not required in osmosis because it is a passive process. Osmosis is technically more or less the selective diffusion of water molecules across a membrane that selectively locks out other larger molecule like ions. Water will, therefore, move from the solution where there are more water molecules to the solution with fewer water molecules.
Answer:
where your baby is at least 37 weeks
Explanation:
In cases where your baby is at least 37 weeks, current research suggests that it may be safe to wait 48 hours (and sometimes longer) for labor to start on its own. (But your caregiver may have a different protocol, like 24 hours.)
