Answer:
The correct answer of Q 1 is- exchanges materials with its environment efficiently.
If a cell has a large surface area to volume ratio than materials can easily move in and out of the cell due to the small size of the cell. As the surface area to volume ratio decreases materials from the surrounding environment move slowly inside the cell.
The correct answer of Q 2 is- moving needed materials in and waste products out.
Large cell requires more nutrients and produce more waste material than smaller cell and their movement is more difficult in larger cell, therefore, cell reduce size by dividing.
The correct answer of Q 3 is- binary fission
Bacterial cells divide by binary fission into two equal half which is a type of asexual reproduction.
The correct answer of Q 4 is- provides genetic diversity
As sexual reproduction require the fusion of gametes from two different individuals it provides genetic diversity in the population.
The correct answer of Q 5 is-meiosis
Meiosis is the type of cell division which helps to reduce the chromosome number by half in sex cell or gametes because in sexual reproduction half of the chromosome comes from one individual and half from another.
