These algae process carbon through photosynthesis and pass it on to corals in the form of glucose, a sugar that provides the energy corals need
Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.

Answer:
Treating the affected area with an alkaline solution or substance such as baking soda.
Explanation:
Neutralization Reaction:
- When an acid and an alkali react chemically, they form water and a corresponding salt. This reaction called the neutralization reaction.
- acid + base (alkali) → salt + water
- E.g HCl + NaOH → NaCl + H2O
- The formic acid that the ant injects can be neutralization by application of an alkali.
- In order to prevent a serious allergic reaction, antihistamines must also be administered.
