Answer:
From this it can be deduced that the fresh water is hypotonic and the salt solution is hypertonic to the cells of the celery stalks.
Explanation:
When submerged in water, the celery stalks become stiff and hard, this shows that water moves within the stalk, thus, water is hypotonic in comparison to the celery stalk. Therefore, water moves from the region of higher concentration to the region of lower concentration.
When the same celery stalk is administered into the 0.15 M solution it turns soft, which shows that water from the celery stalk moves out. Thus, the salt solution is hypertonic in comparison to the celery stalk. Therefore, freshwater is hypertonic and the solution of salt is hypertonic to the celery stalk cells.

Answer:
Endocardium
Explanation:
The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.
The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.
