Biology
1 answer:
lesya [120]3 years ago
7 0

Answer:

John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.

Explanation:

These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.

I recommend to read his article (chapter book):

Jones, JS. (2012). Is Human Evolution Over?. In Evolution 2.0 (pp. 167-176). Springer, Berlin, Heidelberg.

What is an invasive species?
Serga [27]

Answer:

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.

Explanation:

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

Which biological scenario(s) best describes phenotypic plasticity for a trait?
DIA [1.3K]

Answer:

C) II and III only

Explanation:

Option 1 is not an example of phenotypic plasticity because each person is born with their own blood type and this doesn't change based on their environment and behavior.

Option 2 is an example of phenotypic plasticity because a person's red blood cell counts can increase based on their environment, i.e. moving to Denver, CO from Death Valley, CA. The higher elevation and decreased oxygen causes your body to produce more red blood cells.

Option 3 is an example of phenotypic plasticity because one twin can be taller than another because of differing behaviors, environments, etc.
