The autonomic nervous system releases chemical messengers to influence its target organs
Answer:
False
Explanation:
Approximately 200 out of 200 million sperms ejaculated during intercourse reach the general vicinity of the egg. They sperms must undergo capacitation during which dilute inhibitory factors fluids of the female reproductive tract weaken the membrane of the sperm head so that head of the sperm can be broken easily when it came in contact with the egg.
The first sperm to reach an egg isn’t the one to fertilize it because the egg is surrounded by a gelatinous membrane called the zona pellucida. Outside this layer, a layer of small granulosa cells also present.
Therefore, it requires numerous sperm to clear a path through these barriers before one of them can penetrate the egg and fertilize it.
Bears eat plants such as berries, and plants get their energy from the sun. So his energy source's energy source is sunlight, which also makes it his energy source
Answer: Meristems contribute to both primary (taller/longer) and secondary (wider) growth. Explanation: Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium.
Explanation:
Explanation:
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy stored within carbohydrates, like molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy
Carbohydrates molecules that supply energy and provide support; they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.
The energy they store, is required by all living organisms for biological processes; these undergo respiration, in order to release energy stored within its bonds, in the form of the molecule ATP.
