Answer:
1. A Struggle for Survival
2. survival will reproduce
3. Superior adaptive variation
Explanation:
1. Observation: overproduction of offspring that can possibly survive.
CONCLUSION: A Struggle for Survival, most of this offspring fight for food and water.
2. Observation: variation in species: member of the same species have different ways of identification, which are color, sex, e.t.c
CONCLUSION: Those individuals that survive and reproduce do so in consequence of "superior adaptive variation" (they are "more fit")
3. Observation: Variation heritable through selection: most survival pass there favourable adaptation to their offspring.
CONCLUSION: Superior adaptive variation will be passed on to offspring generation.

Solution
Acquired immune deficiency syndrome (AIDS) is an acquired immune deficiency syndrome cause by human immunodeficiency virus (HIV) infection.
CD4+ T lymphocyte is an essential part of in immune responses and an HIV attacks on the immunity of an individuals by killing CD4+ T lymphocyte.
In general, out of total T lymphocytes , there are nearly 65% of CD4+ T lymphocytes a healthy individual. The remaining T lymphocytes are CD8+ T lymphocytes
An HIV infected person, has damaged body's immune system leading to decrease in number of CD4+ T lymphocyte as of hampered CD4+ T lymphocyte production.
Hence, option D is correct
The answer is straight chain, branched chain and ring. The straight chain is called pentene. Branched chain is the hexane. While the ring is Vanillin. Pentene is a colorless flammable liquid with several isomers. Vanillin is a white crystalline solid.Hexane is an organic compound used as solvent.
