Below is the response:
<h3>What does seed germination mean?</h3>
Germination is the first stage of a seed's development into a seedling. To germinate, seeds require the appropriate combination of temperature, oxygen, and water. In a state of suspended animation known as dormancy, seeds wait to germinate until the environment is favorable for their survival and growth.
The option missing in the query is:
Dry cotton wool
wet cotton wool
covered with water
The initial conditions needed for a seed to germinate are as follows:
warm temperatures are needed for effective enzyme operation.
water, where chemical reactions can occur.
oxygen, for breathing.
Observations:
Seeds planted here won't sprout because of the dry cotton wool. Since some of the prerequisites are not met, they won't exhibit any modifications. (Water isn't present.)
Seeds placed on wet cotton wool will germinate since all the circumstances are there for germinations to occur.

The correct answer is option (D) Lipid molecules are nonpolar because they repel water molecules, which are polar.
Lipids are organic compounds made up of fatty acids and glycerol. A glycerol is a organic molecule with three hydroxyl groups and a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.
Lipids are hydrophobic, nonpolar molecules with no charge on their ends. Waxes are long chain nonpolar lipids. The water repelling property of the waxes prevent the water sticking to it and appear as water beads on its surface. The hydrophobic hydrocarbon tail of the fatty acids are hydrophobic in nature making them repel water. The presence of wax on the surface of the plants and animals protects them from dehydration.
Thus, the nonpolar property of lipids make it insoluble in the polar solvents like water as there is no interaction or sharing of electrons between them.
Group 7A, the Halogens contain metalloids such as Astatine.
