Answer:

Cells would most probably not exist because these units of life metabolize energy molecules like glucose to harness their energy for the running of biochemical processes, like active transport, to support life. However, harnessing this energy from these energy molecules is NOT 100 percent efficient. A higher percentage of energy is lost as heat in the process.

Therefore if the cells were required to carry all molecules in and out of the cell, actively, including the energy molecules themselves (which is counterintuitive), this would require a lot of energy and would be unsustainable. This would be analogical to the counteracting and infinite loop of more fuel needed to carry the mass of the more fuel in space travel...

Which of the following populations would be considered r-selected? Black Widow Spiders - they produce 1000s of offspring and few
belka [17]

Answer:

Option 1.

Explanation:

r-selected species may be defined as the species that has higher growth rate, shows less parental care and the rate of survival of the off spring is low as compared  with k selected species.

Black widow spiders have the ability to produce 1000 offspring. Their chances of survival are extremely low and only few species of black widow spiders survive. Hence, black widow spider is r-selected species.

Thus, the correct answer is option (1).
