Explanation:
I wrote out an explanation but it said "Rude! We don't use such words here. Please change it". I honestly don't know what word i couldn't use but I just could not post it. I tried changing any words that may have caused it but it did not fix the issue. So here are the answers only.
 
        
             
        
        
        
Answer:
Option-C
Explanation:
Hamilton gave the mathematical expression for the altruistic behaviour or trait in a population which suggested that the alleles for altruistic behaviour will be favoured by the natural selection if BR-C > 0.
The mathematical expression for the altruistic trait is rb> c
where r - relatedness, b- the benefit to recipient and itself also and c-cost to an actor.
In the given question, all the cases meet the condition of Hamilton's rule except one which is the In- law bee-eaters which raise the young near to the nest as the parents who can raise the young ones are not benefited personally from the action of the young as the young one treat them as non-kin. This does not fulfill the condition of the Hamiltons rule.
Thus, Option-C is correct.
 
        
             
        
        
        
Answer: The first three zones of the ocean are called the Intertidal zone, the Neritic zone, and the Open ocean zone. 
The open-ocean zone is then split into 3 subzones. These subzones are called; <u>The sunlit zone, twilight zone, and the benthic zone. </u>
The sunlit zone is home to the plankton and jellyfish. The twilight zone is home to the giant squid and deep-sea hatchet fish. The benthic zone has over 200,000 plants and animal species that do not need light to survive.
