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.
Correct Answer is A. They were able to increase their productivity due to the popularity of tractors.
In this case, the two species have coevolved by modifying behavioral traits (moths) and physiological traits (bats).
<h3>What is coevolution?</h3>
Coevolution is a particular type of evolution where a selective pressure imposed by one species serves to generate an adaptive change in another species and vice-versa.
Coevolution is fundamental in predator-prey relationships and leads to the emergence of new traits that are selected by natural selection.
In conclusion, the two species above have coevolved by modifying behavioral traits (moths) and physiological traits (bats).

Brainstorm, draft, reread, revise, edit, final draft.
Conclusions should have a hook, bridge, and call to action and/or summary.
Answer:
C) 50%
Explanation:
If wavy hair is heterozygous then wavy is dominent and curly is recessive. So the alles for wavy would be Ww and for curly it would be ww. Put that on a punnet square and it is 50-50
