Elodia [21]

The water cycle is a system that shows how the water moves around in different states to transport itself. It uses different states which show a different transportation such as evaporation or condensation. The water cycle can also use continuous movement above and below the earths surface. There are five main steps to the water cycle which are evaporation, condensation, precipitation, transpiration, and runoff but there are still many more.

Hope this helps! :)

The <span>hardy-weinberg equation is
p2 + 2pq + q2 = 1
where are already given with
c = 0.1 and C = 0.9
SO
p2 = 0.9^2
p2 = 0.81
q2 = 0.01
0.81 + 2pq - 0.01 = 1
2pq = 0.18
The answers are
CC = 0.81
cc = 0.01
Cc = 0.18</span><span />

Consider the evidence that explains how physical separation of two populations of a species can cause speciation. What effect do
Tom [10]

Answer:

  • Interruption in the genetic flow between separated groups
  • The emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations.
  • Genetic divergence by natural selection and reproductive isolation
  • Prezigotic isolation mechanisms

Explanation:

Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.

The process of allopatric speciation involves different steps that affect organisms:

  • The emergence of the barrier.
  • Interruption in the genetic interchange
  • The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
  • Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
  • Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.
