The answer is B, as for the flower to produce seeds, it needs to have been previously fecundated by a male gamete.
Mitosis, it only occurs in organisms whose cells contains chromosomes.
Answer:
Sarcomere
Explanation:
The sarcomere is the smallest contractile unit of muscle. It extends from one Z disc to the next and therefore, is the region between two consecutive Z discs. It contains an A band flanked by half an I band at each end. Contraction of a muscle fiber occurs as the sarcomeres within the myofibrils shorten. During the shortening of the sarcomere, the thin actin filaments slide past the thick myosin filaments and approach one another. The resultant shortening of the I band and complete disappearance of H zone cause contraction of muscle fiber.
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. <span>In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose. </span>
<span>Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. </span><span>Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root. </span>
