Correct answer is B.
Explanation:
In their nucleus cells contain DNA. The DNA has information about size, shape and function of each cell. When the cell reaches it's full size it stops growing and starts doing whatever it's function is. If more cells are needed then the cell replicates. This explanation excludes answers A and C.
Male and female sexual cells are used to conceive a baby. These cells combine to form a new type of cells. In the first few weeks all types of cells are created. Then the creation of new types of cells stops and existing cells multiply in order to achieve needed number of cells. This explanation excludes answer D.
When we compare an adult person and a baby we can see that, for example, an adult has bigger bones than a baby. This was result of increasing number of existing types of cells without creating any new type.
Answer:
correct option is corridors
Explanation:
we know that here in the ecology
to counter habitat fragmentation corridors are being constructed
so here we can say that corridors is a functional component of wild life
it is associate with megafauna whose population they are designed to conserve and Corridors is critical for the maintenance of ecological process
including allow for movement animals and viable populations
regional corridor is primary land scape connection between the large area of habitat
so we can say correct option is corridors
