Answer:
B is the answer I guess for the question
Speciation is the
process by which new and distinct species are formed. One of the most important
factors necessary for speciation to occur is the genetic isolation of two
populations. This genetic isolation can, over long periods of time, cause these
two groups to become genetically incompatible. Factors that can lead to this
genetic isolation include geographic separation and hostility among population
groups.
High melting point
Good conductors of heat and electricity
Lustrous (shiny)
Malleable (can be hammered)
When electrons are added to the outermost shell of a carbon atom, it forms an anion that has a larger radius. An anion always has a larger radius than a neutral atom of the same element. This is because more electrons cause greater repulsion between its nucleus and electrons, making the electrons move farther away from the center.
the answer is C. make pesiticides more toxic
