Which of the following statements is correct?a. Population size of predators increases when their prey is scarce. b.Competition for resources is density-independent when food is plentiful. c.Disease is density-dependent because transmissionoccurs more easily when a population is large. d.A change in average temperature is a density-dependent factor because fewer organisms can acclimate to variations in temperature.

C. Disease is density-dependent because transmission occurs more easily when a population is large

Explanation:

The question examines the knowledge of concepts of factors affecting the population.

A population is the collection of organisms of a particular species, sharing a particular characteristic of interest, most often that of living in a given area.

Option A is false. The population size of predators decreases when their prey is scarce.

Competition in a population involves individuals contending in rivalry for resources.

Option B is false. Competition for resources is density-dependent when food is plentiful.

Option C is true.

Disease is an abnormal condition of a animal or plant in a population that causes discomfort or dysfunction .

The mode of disease transmission actually is density-dependent because transmission occurs more easily when a population is large.

The option D is false.

Temperature is an abiotic factor not a density dependent factor.

A change in average temperature is not density-dependent factor.

The temperature is the measure of cold or heat, often measurable with a thermometer.

C is therefore the correct option.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
