The answer would be B) Transfer heat.
Answer:
The CO molecules would be able to leave the cell faster if the cell had a smaller volume
Explanation:
A smaller volume leads to a greater surface area to the volume ratio. If the cell has a larger volume and grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
These two organisms may have evolved by coevolution. The last option in the given question is the correct option. The Latin-American humming birds had to evolve as per their surroundings, otherwise they would have become extinct in that region. For that sole purpose they had to have the long and curved bills. The flowers needed the humming birds for their pollination. To attach with the legs of the humming birds in the region, the flowers had to become sharply curved. The humming birds had to come in contact with the flower while sucking the nectar. this helped the plants in their pollination process. so both became mutually beneficial to each other.
The atom? gas? either one of those two would work
Plant has such a developed structure to protect they have cell wall which give it rigidity and structure and also have cellulose which provide strength
