Answer:
D. Population genetics
Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.
Explanation:
microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then
macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then
gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then
So it has to be D
Answer:
population - community - ecosystem - biosphere
Explanation:
<em>The correctly sorted level of organization of an ecosystem from the least inclusive to the most inclusive would be from population to community to ecosystem and finally to biosphere.</em>
A population consists of a group of organism of the same species living in a particular area at a particular time and capable of interbreeding to produce fertile progeny.
A community represents different population of organisms that are interacting with one another. Several populations make up a community.
An ecosystem consists of different communities of organisms that are interacting with themselves and the non living component of the environment.
A biosphere consists of all regions of the earth where living organisms can be found. It consists of different ecosystems that make up the earth.
<u>Hence, the population is least inclusive, followed by the community, then the ecosystem and finally the biosphere.</u>
This is an example of; evolution
Evolution is a gradual process in which the characteristics of a species are changed in response to its environment over several generations. Evolution depends on the process of natural selection. Some of the changed characteristics (traits) may be beneficial to the organism and it can be transferred to their offspring.
Answer:
Option B, It increases the probability that some offspring will survive long enough to reproduce.
Explanation:
The larger the number of eggs, the larger will be the available opportunities for at least few of the youngsters to develop into adult being and survive till the age of fertility. This shall enhance the chances of producing new offspring before the older one dies thereby replacing them without changing the population number and further producing offspring that can survive to replace them and continue this chain.
Hence, option B is correct
The answer is to this question is True.
