Techniques have been developed to expand both the diversity of nucleotide or ... By the early 1970s, scientists had demonstrated that they could engineer synthetic genes.
Explanation:
Answer:
Active
Explanation:
Endocytosis is a type of active transport where large molecules or even cells are moved inside the cell.
Answer:
These molecules are always in motion and higher temperature gives them more energy and they vibrate more rapidly and hence have higher kinetic energy. One effect of this rapid motion (high kinetic energy at higher temperatures) is the expansion observed, when we heat a substance.
Hope this helps.
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.
