Blood pressure is a cognitive process because it is observable with lab equipment. T F.
Harrizon [31]

Blood pressure is defined as the pressure of the blood at which it is flowing through the blood vessels. It is measured by different lab equipment.

The given statement is false.

Cognitive properties refer to sensation, attention, and perception. The ability to solve problems, perform mental operations, learn languages and reasoning are also some of the cognitive abilities.

Cognitive abilities are calculated or estimated by a series of tests and activities, it is not measurable with a piece of equipment.

Blood pressure is a normal physiological activity, which functions to deliver blood and oxygen to all parts of the body. Blood pressure can be measured by the lab types of equipment but is not a cognitive activity.

Thus, the given statement is False.

Celery stalks that are immersed in fresh water for several hours become stiff and hard. Similar stalks left in a 0.15 M salt sol
Vedmedyk [2.9K]

Answer:

B. the fresh water is hypertonic and the salt solution is hypotonic to the cells of the celery stalks.  

Explanation:

A hypertonic medium is precisely one that has a higher solute concentration than another medium. This, in turn, is hypotonic compared to the former. Thus, these classifications can only be employed in the sense of comparison and not as the primary definition of the osmotic characteristic of a solution.

When a cell is placed in a hypertonic solution, that cell tends to seek osmotic balance and absorbs some of the solution's solutes becoming rigid and hard. For this reason, we can say that fresh water is hypertonic in relation to celery stem cells.

On the other hand, when the solution is hypotonic, the cell trying to reach an osmotic equilibrium loses part of its solutes to the solution, becoming soft and flabby. For this reason, we can say that saline is hypotonic for celery stem cells.
