The characteristics of life are
-Having cells
-Growing
-Responding to its enviornment
-Having DNA
-Consuming and or using energy
-Reproducing
-Maintaining homiostasis
Viruses are not considerd alive because they dind
-Have DNA
-Have cells
-Maintain homiostasis
-Consume energy
Population density is the aspect of population ecology of the black-tailed prairie dog does this statement describe.
Explanation:
Population density is the number of organisms are there in per unit area. It is used to measure geographical area occupied by organisms and its statistics.
In population ecology the structure, dynamics and contribution of population of species is studied. The idea of species distribution is studied in it.
The population density determines the number of species or members of particular population are present is a particular area.
An area of low density population will have more resources and more area per organism and less competition for resources and vice versa for high density population.
Prairie dogs have 12 adults per hectare of area this tells the population density of the rodents.

Answer:1.Selection of the dark-colored moths over light-colored moths after industrial evolution is an example of directional selection while selection of alpha males and “sneaking” males over intermediate males in a lobster population is an example of disruptive selection.
2.organism in which they occur. They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur.
Explanation:
i really hopes this helps
They play huge role in organisms, every living organism needs proteins.
- enzymatic role ( they build enzymes which lower an activation energy in reactions and increase reaction speed)
- hormonal role (they build hormons)
- structural role (for example keratin)
- transport role ( for example hemoglobin)
- energetic role ( for example aleurone grains in plant cells or they are used to gain energy in human organism when it's out of lipids and carbohydrates)
