The correlation coefficient (r) indicates a strong positive correlation with r = 0.9. The stronger the bond, the closer the relationship. Option B is true. As it is nearly 1 so it is the correct.
<h3>What is the Hamilton Rule?</h3>
Hamilton established the rule governing the costs and benefits of altruistic behavior in organisms. Here in rB>C, the r is relatedness between the beneficiary and the cost to the donor. The stronger their bond, the more likely it is that one will make a sacrifice for the other. In the parent-offspring case, the relatedness is 0.5 because half of the genetic content comes from each parent to the offspring. The greater the genetic distance between two people, the lower the r value and the lower the likelihood of altruism.
Hence, option B is correct as here r is 0.9, which is the highest among all four options.

The best answer to fill in the blank is "multilayered membrane."
Correct answer: A). Chemical
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane, chlorophyll absorbs the energy from the sunlight. After that, the light energy is converted into chemical energy by using water. Then the lower energy NADP+ get high energy electrons and protons and get converted into NADPH and ATP.
The answer is commensalism.
The complete answer is: The ecological relationship between organisms where one benefits and the other is not affected is commensalism.
There are four kind of ecological relationships between two organisms: mutualism, amensalism, parasitism, commensalism.
In mutualism the two organisms benefit from each other.
In amensalism one organism in unnafected and the other is harmed.
In parasitism one organism is benefited ant the other harmed.
Answer:
D. A brown gas produced
Explanation:
When a chemical reaction occur, there are several changes that takes place such as change in color, odor change, formation of a gas, and formation of a precipitate etcetera.
In the given chemical reaction, two colorless gas (NO and O2) react together and form brown gas (NO2). So, the change of gas from colorless to brown gas is the evidence that shows chemical reaction occurred.
Hence, the correct option is "D. A brown gas produced".
