Answer:
Parasites
Explanation:
Parasites are found on or in the body of the host and they get food by eating the host's partly digested food therefore, depriving it of nutrients which then deprives the host's ability to reproduce. This energyis diverted into parasite growth. The host's other systems are left intact, allowing it to survive and sustain the parasite.
Answer:
B. NADH
Explanation:
For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced.
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.
Answer:D) all of the above
Explanation:these are all correct because they all affect our environment
