Answer:You have learned that photosynthesis always brings new food to the earth. There is another reason why photosynthesis is so important. Oxygen is produced during photosynthesis. Humans and animals need oxygen to stay alive. Plants themselves also need oxygen. Through the photosynthesis, new oxygen is constantly coming into the air. Without photosynthesis, the oxygen in the air would slowly run out. All living beings would then die. In many plants, photosynthesis does not only occur in the leaves. Photosynthesis can take place in all green parts of a plant. For plants with green stems, photosynthesis also takes place in the stems. But most photosynthesis takes place in the leaves. The leaves therefore have the special function of allowing photosynthesis to take place.

Explanation:
The process of DNA replication is a semi-conservative process; therefore each newly replicated helices contains one strand from the parent, and one daughter strand.
Explanation;
Replication of DNA is an important process especially during cell division, The two strands of DNA molecule have complementary base pairs and therefore, each of these strands contains the information needed to produce another strand. Each can be used as a pattern or template to produce a complementary strand. Finally each template and its new complement together form a new DNA helix, identical to the original. This is referred to as semi-conservative process because each new strand formed would have one strand from the original DNA molecule and a new complementary strand.
