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.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
