What is photosynthesis?

The process of synthesizing organic materials by plants for their nutrition by the use of inorganic raw materials is called photosynthesis. This process utilizes light. That is why it's called photosynthesis, photos meaning light.

The inorganic raw materials that are used are carbon dioxide and water. The light energy is derived from the sun and captured by the chlorophyll present in the plants.

The light energy is converted to chemical energy which is used for splitting the water molecule into hydrogen and oxygen. Hydrogen is used for the reduction of carbon dioxide for the formation of glucose.

The oxygen is released into the atmosphere as a byproduct. The glucose formed in the main product is further utilized by plants for the production of energy in the process of cellular respiration.

Therefore, the correct option is C.

Why is DNA antiparallel? It has double strands complementing each other. The bases in one strand pair with the other bases in the complementary strand. It has a ladder shape. Its double strands run in opposite directions.

Answers

Answer: DNA is antiparallel because Its double strands run in opposite directions.

Explanation: The antiparallel nature of DNA strands means that as one strand runs in 5'->3' direction, the other strand runs in 3'->5' direction. The two antiparallel DNA strands are not identical in either base sequence or composition rather they are complementary to each other. This means that anywhere thymine base is found in one strand, adenine is present in the other strand and anywhere guanine occurs in one strand, cytosine occurs in the other strand.
