Answer:
Cuando escucho hablar sobre la tabla periódica se viene a mi mente que es una forma de organizar todos los elementos que existen.
Explanation:
La tabla periódica tiene como fin organizar a la gran diversidad de elementos químicos que existen agrupándolos según sus propiedades. De esta forma, podemos ver que elementos tienen cualidades similares entre si y predecir como reaccionarían con otros elementos de la tabla periódica. En otras palabras, es una forma ordenada y simple de mostrar las características de cada elemento y articularlo con los demás según sus características.
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).
Answer:
Option (3).
Explanation:
The homeostasis of the body is maintained by the feed back loop system. Two main types of the feedback loop system of the body are positive feedback system and negative feedback system.
Positive feedback system may be defined as the feedback in which the final product increases the output of that product. Pepsinogen is an zymogen that helps in the activation of pepsin enzyme. This enzyme helps in the digestion of protein. The digestion of pepsinogen by pepsin result in the more production of pepsin.
Thus, the correct answer is option (3).
Answer:
is based on the fact that certain enzymes and chemical processes are found in the cells of all or nearly all life on Earth.
Answer:
A lymphocyte is a type of white blood cell that is part of the immune system. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body's own cells that have themselves been taken over by viruses or become cancerous.
