b.) a high birth to death ratio
c.) immigration
d.) large number of resources
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:
An increase in temperature would increase the rate of osmosis in cells. This is because the higher temperature would increase the kinetic energy of the water molecules, making them move faster and more easily across the semi-permeable membrane.
The rate of osmosis is affected by a number of factors, including temperature, concentration gradient, and membrane permeability. The temperature is the most important factor, and a 10°C increase in temperature can typically double the rate of osmosis.
In cells, the water concentration is typically higher outside the cell than inside the cell. This creates a concentration gradient, which drives the movement of water into the cell. The membrane surrounding the cell is semi-permeable, which means that it allows water molecules to pass through but not other molecules, such as solutes.
Therefore, An increase in temperature would increase the rate of osmosis in cells.

Explanation: Factors Affecting the Rate of Osmosis
Temperature - The higher the temperature, the faster the movement of water molecules across the semi permeable membrane.
Osmosis is the passage of water from a low solute concentration area through a semi-permeable membrane to a high solute concentration area to equalize the solute concentrations on both sides. Meaning of the terms: solute, solvent and solution. A solvent is the base substance, where a solute is being dissolved and the result is the solution. Through osmosis, water is provided to the cells of your body; it plays a significant role in the preservation of life. It is this process that helps plants receive water and is even used in kidney dialysis.
A an ecosystem B a community C a population D a trophic level
A group of organisms of a certain species present in one area at a given time is called a population. So the correct option is C.
The entire number of inhabitants of a particular area counted at a particular time is referred to as the population of that area. The population of any area is never stagnant and it is continuously changing. A day after a count a new individual might be born and someone might die.
The population is controlled by various limitingfactors. These are the availability of living space. Availability of food, habitat, and presence of predators are some of the factors that control the population of a species and act as limiting factors.
The population of a species are able to interbreed within themselves to produce similar organisms to continue the population.
A reduction in the size of a population is called a populationbottleneck and an increase in the size of a population is called overpopulation.
Therefore the correct option is C.
