Answer:
The circulatory system has evolved over time from simple diffusion through cells, in the early evolution of animals, to a complex network of blood vessels that reach all parts of the human body. Made of specialized and unique cardiac muscle, it pumps blood throughout the body and to the heart itself.
Claps shut at birth. Evolutionary changes in the vertebrate heart are tied to change from single to double-circuit heart, with increased separation of oxygenated and deoxygenated blood, allowing more efficient respiration and circulation to fuel high activity and increased oxygen demands associated with endothermy.
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein
Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.

What is photosynthesis?</h3>
Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.
In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.
The following is a balanced chemical reaction for photosynthesis:
Sunlight
6CO2 + 6H2O —---------> C6H12O6 + 6O2.
(carbon (water) (glucose) (oxygen)
dioxide)
