Answer:
The answer is when the cell express different genes.
Explanation:
Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.
<span>When a new species form by geographic isolation, it is called
geographical speciation or allopatric speciation. Geographical isolation is
a physical separation which prevents gene flow between distinct
populations. The populations on three land masses from this example, will eventually diverge from individuals of the single species that migrated to those land masses.
The members of the populations, which once belonged to the same species,
will no longer be able to mate and produce offspring. Eventually,
the formation of new species will occur, in this example three new species on three land masses from the ancestral Adansonia species.</span>
The forest ecosystem is a living resource ( true)
Answer:
True
Explanation:
This is true because any element or compound with hydrocarbons tend to be non-polar.
