C - Angiosperms
Hope that helps! :)
The answer is b. the decreased migration of pests and pathogens
Answer:
The answers would be A and D I think
Explanation:
<span>The factors which are common to both gradualism and punctuated equilibrium are found in the first option - migration, genetic drift, speciation, and natural selection. Both gradualism and punctuated equlibrium go through these 4 phases. Gradualism, as opposed to punctualism, is a theory that proposes that evolution is a process created through gradual changes, as opposed to immediate ones.</span>
Answer:
The letter B is the right answer.
Explanation:
The main objective of the hardin and Weinberg equilibrium is to determine how the allelic frequencies change within a population.
In 1908, Godfrey H. Hardy (1877-1947) and the German physician, Wilhem Weinberg, proposed that if no evolutionary factors act on a given population, the frequencies of their alleles would remain unchanged for several generations. This proposal became known as Hardy-Weinberg's Law (or theorem) or principle of gene balance.
According to this law, the necessary conditions for a population to reach equilibrium are:
a) The population must be large, so that all possible intersections occur.
b) The population must be panmatic (from the Greek pan, all, and from the Latin miscere, mix), that is, the crossings must be carried out randomly, without preconditions.
Within these conditions, without mutation, migration or selection, there will be a genetic balance. Over the generations, genes will not change.
