The right answer is solar for the first one and chemical for the second one.
Photosynthesis aims to create energy (in the form of carbohydrate) from the light energy from the sun. The organisms that use the photosynthesis mechanism are autotrophic because they make organic materials from inorganic materials.
Solar energy is used to oxidize water and reduce carbon dioxide to synthesize organic substances (carbohydrates). This phenomenon occurs in chloroplasts, a plant-specific organelle, at the level of the thylakoid membranes where photosystems I and II and cytochromes are located.
Answer - A Semi-conservative model of replication involves the replication of DNA in all the familiar cells in such a way that each newly synthesized daughter cell contains a double helix with one new strand and one old strand.
