Q: Where are bile acids, needed to emulsify lipids, stored in the body? Read this paragraph and choose the correct option from the provided answers: Triglycerides in the diet are digested in the small intestine. Since lipids are not water-soluble, they are emulsified with the help of bile acids, which are produced by the liver and stored in the gall bladder. Bile acids are cholesterol-derived steroids that also contain a water-soluble component. The nonpolar region of these acids can interact with triglycerides, and the water-soluble portion allows the entire complex to dissolve in the aqueous environment within the body. Choices: - liver - womb - cerebellum - gallbladder A:
gallbladder

Q: What is the muscular organ shaped like an upside-down pear that has a thick lining of tissues called the endometrium? Read this paragraph and choose the correct option from the provided answers: The uterus is a muscular organ shaped like an upside-down pear. It has a thick lining of tissues called the endometrium . The lower, narrower end of the uterus is known as the cervix . The uterus is where a fetus grows and develops until birth. During pregnancy, the uterus can expand greatly to make room for the baby as it grows. During birth, contractions of the muscular walls of the uterus push the baby through the cervix and out of the body. Choices: - kidney - lungs - liver - uterus A:
(Answer)
uterus

Ques: Q: What is the term used for a large body of air of the same temperature and moisture conditions? Read this paragraph and choose the correct option from the provided answers: An air mass is a large body of air that has about the same conditions throughout. For example, an air mass might have cold dry air. Another air mass might have warm moist air. The conditions in an air mass depend on where the air mass formed. Choices: - air group - sky mass - air pool - air mass A:
Ans: air mass

(Q).
Q: Air quality is a measure of what in the air? Read this paragraph and choose the correct option from the provided answers: Air quality is a measure of the pollutants in the air. More pollutants mean poorer air quality. Poor air quality started to become a serious problem after the Industrial Revolution. Factories burned coal for energy. Gasoline burned by cars and trucks added greatly to air pollution. By the mid-1900s, air quality in many big cities was very bad. Incidents in London and in U. S. cities alerted people to the extent of the problem. It was clear that air quality needed to be protected. Choices: - clouds - gases - water - pollutants A:
(A).
pollutants

Ques:Q: What gland is located at the base of the brain and secretes the hormone melatonin? Read this paragraph and choose the correct option from the provided answers: The pineal gland is a tiny gland located at the base of the brain. It secretes the hormone melatonin. This hormone controls sleep-wake cycles and several other processes. Choices: - thymus - pituitary - thyroid - pineal A:

Ans:pineal

Ques: Q: Water follows where sodium ions lead, due to what process? Read this paragraph and choose the correct option from the provided answers: Blood Pressure Regulation Due to osmosis, water follows where Na+ leads. Much of the water the kidneys recover from the forming urine follows the reabsorption of Na+. ADH stimulation of aquaporin channels allows for regulation of water recovery in the collecting ducts. Normally, all of the glucose is recovered, but loss of glucose control (diabetes mellitus) may result in an osmotic dieresis severe enough to produce severe dehydration and death. A loss of renal function means a loss of effective vascular volume control, leading to hypotension (low blood pressure) or hypertension (high blood pressure), which can lead to stroke, heart attack, and aneurysm formation. The kidneys cooperate with the lungs, liver, and adrenal cortex through the reninangiotensinaldosterone system (see Figure 25.14). The liver synthesizes and secretes the inactive precursor angiotensinogen. When the blood pressure is low, the kidney synthesizes and releases renin. Renin converts angiotensinogen into angiotensin I, and ACE produced in the lung converts angiotensin I into biologically active angiotensin II (Figure 25.23). The immediate and short-term effect of angiotensin II is to raise blood pressure by causing widespread vasoconstriction. angiotensin II also stimulates the adrenal. Choices: - electrolysis - absorption - hydration - osmosis A:
Ans:
osmosis
