Answer:
This question lacks options, options are:
A) ADH
B) aldosterone
C) atrial natriuretic hormone
D) oxytocin
E) prolactin
The correct answer is B.
Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of <u>aldosterone</u>.
Explanation:
The female sex hormones produced by the ovary (estrogens and progesterone) are substances that, through the blood, will carry messages to all the organs of the female genital system (uterus, tubes and ovaries) to achieve their correct function. Aldosterone concentration normally increases at the time of ovulation and remains elevated during the luteal phase of the menstrual cycle. Women present during the premenstrual phase, compared to the luteal and follicular phases, an increase in body weight, due to an increase in fluid retention, this because the menstrual cycle modulates the renin-angiotensin-aldosterone system. High levels of estrogen and progesterone in the mid-luteal phase are associated with a greater increase in adrenal and renal hormones and retention of more volume.
The answer is; Sodium (Na+) and Potassium (K+) Ions
These cations are pumped out of the cell by Na+-K+ transmembrane protein pumps leaving the inside of the cell electronegative in relation to the extracellular matrix. This membrane potential is significant especially for neurons. Depolarization of the membrane enables transmissions of an impulse along the neurons.
Answer: Having a non-functional vestibular apparatus.
Explanation:
Motion sickness is a feeling of sickness that is caused by the movement. It occurs in a vehicle like boat, car, train or bus. It can also occur in the amusement rides. This is not life-threatening. It can make the ride or traveling unpleasant. Motion sickness happens when the brain receives the disturbing message related to the motion and the body's position. These messages are delivered from the ear, eyes, skin receptor, muscles and the joints sensors.
Among the options given, Having a non-functional vestibular apparatus. is not the associated with the development of motion sickness. The vestibular apparatus is associated with ear if the ear sensory system becomes non-functional then it will reduce the sensing of motion sickness.
