7. Hibernation and Dormancy

8. Communication

Overall, instincts are essential for animals to navigate their environment, find resources, interact with others of their kind, and ensure the continuation of their species.

Hence, answer for the question is option D instincts.

Explanation:
Increasing the radius of a circle by 1% will result in a proportional increase in its area. Let's calculate the percentage increase in the area of the circle.

Calculations:
Let's assume the original radius of the circle is 'r' units. The area of the circle is given by the formula A = πr^2.
After increasing the radius by 1%, the new radius becomes (r + 0.01r) = 1.01r units. Therefore, the new area of the circle is A' = π(1.01r)^2 = π(1.0201r^2).
Now, let's find the percentage increase in the area of the circle:
Percentage Increase = [(New Area - Original Area) / Original Area] * 100%
= [(π(1.0201r^2) - πr^2) / πr^2] * 100%
= [(1.0201 - 1) / 1] * 100%
= 0.0201 * 100%
= 2.01%
Therefore, the area of the circle increases by 2.01% when the radius is increased by 1%.
So, the correct answer is option D - 2.01%.

Understanding Future Perfect Tense
In the sentence "You will have finished this work by tomorrow," the construction used is the future perfect tense. This tense is employed to describe actions that will be completed before a specific point in the future.
Why Option C is Correct
- Structure of Future Perfect Tense:
- The correct form is "will have been + past participle."
- This indicates an action that is expected to be completed before a certain time.
- Key Elements in Option C:
- "This work will have been finished" indicates that the action of finishing the work is expected to be completed before the deadline of "tomorrow."
- The use of "by" specifies the time frame, making it clear that the completion is expected to occur before tomorrow.
Analyzing Other Options
- Option A: "This work will be finished by tomorrow."
- This is future simple tense. It lacks the nuance of completion before a deadline.
- Option B: "This work will finished tomorrow."
- This option is grammatically incorrect; it omits the auxiliary verb "be."
- Option D: "This work will have been finished tomorrow."
- This construction incorrectly suggests that the completion is expected to happen at the moment of "tomorrow" rather than before it.
Conclusion
Option C accurately expresses the intended meaning of completion by a specified future time. Understanding the future perfect tense helps convey precise timelines in communication.
