The right option is; Hooke
Robert Hooke was an English scientist that first recognized the cell as the universal unit of life. In 1665, Robert Hooke observed honeycomb-like structure when he viewed very tiny slices of cork using a coarse compound microscope. He called the structures cells but he did not know their actual structure and function.
-1 or negative 1. Protons have a positive charge and electrons are negative. So 8+(-9) = -1
Answer:
Populations evolve, individuals do not
Explanation:
I don't really know the explanation I just figured it out by searching it up.
The brain is part of the central nervous system
Answer:
a. a portion of the population becomes isolated from the remainder of the population and experiences different selective pressures
Explanation:
This is an example of allopatric speciation Allopatric speciation is a form of speciation (formation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
For example, Galapagos finches are isolated from others by the ocean (geographic isolation). Because of the isolation, the finches don’t breed with one another. So, they developed unique characteristics and became endemic.
