Answer:
Explanation:
It is important that a cell undergoes replication before cell division occurs because, the main goal of cell division is to make more cells. And for all these cells to remain functional, all their components must be intact and complete. without this, these cells might not function. Thus, the goal of replication is to produce the next new copy that would go into one of the daughter cells produced. With DNA replication, the set of DNA present in a cell can be duplicated and then each daughter cell that results from division can have its own entire set of DNA and then cell division can theoretically continue as normal indefinitely.

Answer:
Gas exchange
Explanation:
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Answer:
A. Water molecules are split.
Explanation:
The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.
These electron carriers are used in the light-independent reactions of photosynthesis.
During this process, the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis
