Answer:
C. DNA ligase adds nucleotides to the lagging strand
Explanation:
DNA replication is the process during cell division in which DNA copies itself. DNA strands unwind with the help of helicase to initiate the process. DNA Polymerase III is responsible for prokaryotic replication and adds nucleotides in 5' to 3' direction. Since both the strands of DNA run in opposite direction their replication is slightly different. The lagging strand is also formed by DNA Polymerase III in discontinuous manner leading to formation of Okazaki fragments. DNA ligase joins these fragments once the replication process is completed.
Gas exchange occurs in the alveoli of the lungs and each is made from a single layer of flat cells, Many alveoli in the lungs, so a large surface area for exchangement of C02 and O2. They are surrounded by a network of capillaries and oxygen diffuses out of them via the alveolar epithelium to the hemoglobin.

Is this a multiple choice question?
Answer:
The correct answer is c. water to move out of the strawberry, making it smaller
Explanation:
Osmosis is the process refers to the movement of liquid molecule from the area of high solute concentration to an area of low solute concentration through a semipermeable membrane to equalize the osmotic balance.
Osmosis is important for any cell to maintain a proper osmotic balance of the cell. So if sugar is sprinkled on a strawberry the solute concentration outside the strawberry cells will increase which will result in water release from the cell.
This release of water from the cell will shrink the strawberry and make it small. Therefore the correct answer is c.
