The answer is: B - Mitochondria
Explanation:
The mitochondria is the powerhouse of the cell.
The main function of the mitochondria is to provide energy for cellular activity by the process of aerobic respiration. In this process, glucose is broken down in the cell's cytoplasm to form pyruvic acid, which is transported into the mitochondrion.
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
Noctiluca is a dinoflagellate in the Domain Eukaryota, Superphylum Alveolata, Phylum Dinoflagellata, in the class Noctiluciphyceae, and in the order Noctilucales.
Explanation:
Stress response by the body is regulated by the nervous system. As the day of the exam draws by, the cerebral cortex of the student activates the hypothalamus that triggers hormones to be released that activates the systemic branch of the autonomic nervous and endocrine system (Larissa, 2018). The autonomic nervous system controls involuntary bodily responses such as breathing, heartbeat, and digestion. The endocrine system contains glands that secrete hormones into the bloodstream that regulate the functions of body organs. The student's pituitary gland in response to the activated hypothalamus, which would secrete a hormone which in turn triggers the release of stress hormones from the adrenal glands and it would help the student manage stress by making nutrients available to meet the demand for energy. These hormones activate the sympathetic division of the autonomic system, causing increased heart rate, breathing, and blood pressure and the suppression of digestion (America psychological association, 2019). After the exam, the student is restored to a less tressful state. The parasympathetic branch of the autonomic system would slow the student's heartbeat and breathing and digestive processes would no longer be suppressed and the student gains appetite for food (BcCampus, 2019).
