Answer:
Explanation:
A gene pool typically has two or more alleles for a given trait. Homozygous lethal traits can be carried by heterozygous individuals and thus remain in a gene pool. Relative Frequency is the number of times an allele occurs in a gene pool compared with the number of times other alleles occur.
They both deal with diseases just that pathogens cause disease while antibodies fight against disease
Answer:
b) Systematics
Explanation:
Darwin presented the theory of evolution and explained that the process of evolution occured because of natural selection which further explains that offsprings are produced from organisms and these organisms are able to survive in their environment.
As systematics is the branch of biology, which basically deals with evolutionary relationships of the organisms .Thus the darwin theory of evolution will be considered in the field of systematics.
Hence the option B) Systematics is the right option.
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance. Example- Primary succession occurs following an opening of a pristine habitat like a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
