Answer:
Natural Resource.
Explanation:
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources
Answer:
The correct answer is option C.
Explanation:
The slugs prefer pink flowers over the white ones. Thus, if the slugs are withdrawn from the population, the pink flowers are no more consumed and their number enhances. In a similar manner, the bees like to pollinate more pink flowers in comparison to the white ones.
Thus, again, the pink flowers are getting pollinated in huge concentrations. Thus, the fruits and seeds are set and they produce another generation of pink flowers. Ultimately, there would be more pink flowers in the region in comparison to the white ones as the slugs that used to consume them, are also withdrawn.
Earlier, both the numbers of pink and white flowers would remain steady as even though only some of the bees were pollinating white flowers, they were not getting consumed by the slugs. This had maintained a balance between the number of pink and white flowers. Thus, the number of pink flowers would increase with time if the slugs are removed.
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.
Explanation:
After repeated stimulation by antigen, B cells can make antibodies that bind their antigen with much higher affinity a process called affinity maturation. ... Thus, antigen stimulation greatly increases the antibody arsenal. Antibodies are proteins, and proteins are encoded by genes.
