The two types of microscopes are electron and optical microscopes.
Electron microscopes have a higher magnifying power since it uses lighting technology to do so.
Hope it helped,
Happy homework/ study/ exam!
Explanation:
The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.
Answer:
I think an image is missing from this question
Answer:
A cold front pushes warm air upward and the cold front collides with a cold front
Answer:
This assertion is false since it depends on the type of selection exerted on the trait under investigation
Explanation:
Geographic isolation is caused by physical barriers such as, for example, rivers, mountains, longer distances, etc, which prevent the interchange of genetic material among populations of the same species. Over time, complete geographic isolation leads to genetic isolation among populations and the development of reproductive barriers, resulting in the separation in two species (speciation). Intermediate populations prevent speciation by enabling gene flow among populations. In consequence, intermediate populations often exhibit intermediate traits as a consequence of bidirectional gene flow; however, there are cases where a given trait is favored by non-directional selection, thereby favoring phenotypic values exhibited by marginal populations localized at the extreme distributional range of the species.
