The correct answer is: A) phenol
Phenol is an aromatic organic molecule that consists of phenyl group (−C6H5) bonded to a hydroxyl group (−OH). This compound is very useful in industry for the synthesis of plastics, nylon, detergents, herbicides etc.
Triacylglycerol consists of glycerol and three fatty acids and it is one of the main constituents of body fat.

Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL
Answer:
B) Mitochondrion
Explanation:
Mitochondria play a pivotal role in apoptosis. Apoptosis or programmed cell death can be initiated by both intracellular and extracellular signals. Mitochondria are responsible for mediating apoptosis initiated by intracellular signals. These are membrane-bound, rod-shaped organelles found in most eukaryotic organisms.
