B & C

A

Explanation:

The organism in option D appears only in the outcrop 4 and is not visible in any of the three outcrops. Thus, this organism can be considered as to be least appearing

Hence, option D is correct

The oldest organisms are found at the lowest layer and hence organism in option B and C can be considered as the oldest as they are found in the second most lower layer of their respective outcrops.

Index fossils are the most abundant one. These fossils are easily traceable and must have faced wide range of evolution. Option A fossil is Ammonite which is the most common index fossil known till date

Hence, option A is correct.

a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.

the process of gradual or unconscious assimilation of ideas, knowledge, etc.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Adrenal glands

​-When confronted with a stressor, the adrenal glands respond by producing stress hormones, including catecholamines, cortisol, and epinephrine.

-In response to acute stress, the body's sympathetic nervous system is activated due to the sudden release of hormones. The sympathetic nervous systems stimulate the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline.

-These "stress hormones" cause several changes in the body, including an increase in heart rate and blood pressure.
