The condition that would lead to a small population size is a low birth-to-death ratio. Thus, the correct option for this question is A.
According to genetics and population ecology, Population size may be defined as the number of individual organisms in a population. Population size may directly depend on evolutionary forces like genetic drift, mutation, etc.
A low birth-to-death ratio means the number of birth is usually smaller than that of the death in any population. So, the size of the population gradually decreases.
While a high birth-to-death ratio means the number of birth is usually larger than that of the death in any population. So, the size of the population gradually increases. Immigration and a large number of resources are also the conditions that lead to the large population size.
Therefore, a low birth-to-death ratio is a condition that would lead to small population size. Thus, the correct option for this question is A.

Answer:
option A
Explanation:
b. Crude oil
c. Natural gas
d. Nuclear energy
Nuclear energy is not considered as a fossil fuel. Thus, option D is current.
Nuclear energy is not considered a fossil fuel. Fossil fuels are formed from the remains of ancient plants and animals that were buried and subjected to high pressure and temperature over millions of years. Coal, crude oil, and natural gas are examples of fossil fuels.
On the other hand, nuclear energy is generated through the process of nuclear fission, where the nucleus of an atom is split, releasing a large amount of energy. It is not derived from organic matter and does not involve the burning of fossil fuels. Instead, it relies on the utilization of radioactive materials, such as uranium or plutonium, to produce heat and generate electricity.

The porins are the membrane proteins, which allows the transfer of the molecules. It is a transport protein. The cipro-resistance protein is also a transport protein. Both the porins and the cipro resistance proteins are membrane transport protein. The presence of the cipro-resistance protein does not allow the ciproflaxin drug molecule to cross through the normal protein, as a result it causes resistance.
