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.
Explanation:
Semi-conductive describes a component which conducts electricity less well than a good conductor but better than an insulator.
The hose should be semi-conductive, with a resistance high enough to insulate a stray current but conductive enough to get rid of static charge build-up.
Carbon black can be used to lower the resistivity of plastics, imparting antistatic, semi-conductive, or conductive properties.
Semi-conductive describes a component which conducts electricity less well than a good conductor but better than an insulator.
The scientist can tell that punctured equilibrium has occurred if they have examined the fossil fuels and can see that one organism rapidly evolved different characteristics.
Answer: Option D
<u>Explanation:</u>
Punctured Equilibrium is an evolutionary theory which proposes that the species appearing in the fossil's record will show little evolutionary changes. In punctuated equilibrium, change occurs gradually, First very little change can be seen which later results in the occurrence of huge changes.
Such huge changes can be clearly seen by examining the fossil records. Thus if there is any evolutionary changes seen in the fossil's record, the scientist can conclude the occurrence of punctuated equilibrium.
