Explanation:
Given -
Mean fruit weight of tomato plant (M1) 
g
Narrow sense heritability (h2) 
g
Mean weight of tomato plant selected for artificial selection (M0) 
g
Substituting the given values in above equation, we get -

Answer:
Membrane markers allow cells to recognize one another, which is vital for cellular signaling processes that influence tissue and organ formation during early development. This marking function also plays a later role in the “self”-versus-“non-self” distinction of the immune response.
Explanation:
Answer:
Option C, To study ecology, we must separate living organisms from their environment
Explanation:
Environmental interaction between living organisms and the environment involves all the biological process such as nutrient cycle, ecosystems, food chains and food web, energy pyramids and relationship, response of an organism towards the changing environmental conditions, evolution, connection with all physical things etc.
In an ecosystem, the impact (both negative and positive) of both the living organism and environment is studied on each other by understanding their relationship for which presence of both of them is essential.
Hence, option C is correct
The Correct choice is " a "
