Answer:
The process where part of the DNA is saved during replication is known as semi conservative replication.
Explanation:
During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid). When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied during the cell division cycle. During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus
of a cell during the s stage of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.

Cellular homeostasis involves maintaining a balance of several factors that make a cell healthy. The cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
Answer:
All types of living organisms use cellular respiration for the production of energy from food molecules such as glucose.
Explanation:
Respiration is energy releasing process which occurs in mitochondria of the cell. Respiration has two types i. e. Aerobic and anaerobic respiration. In aerobic respiration, energy is released from the breakdown of glucose molecules with the addition of oxygen while anaerobic respiration is the release of energy from breakdown of glucose molecules without the use of oxygen.
