Which statement below correctly describes the movement of molecules in the body and/or in
relation to the external environment?
A. Osmosis is the movement of a solution from and area of low solute concentration to an area of
high solute concentration.
B. Diffusion is the process in the lungs by which oxygen is transported from the air to the blood.
C. Dissipation is the transport of molecules across a semipermeable membrane from an area of
low concentration to high concentration, requiring energy.
D. Reverse osmosis is the movement of molecules in a solution from an area of high
concentration to an area of lower concentration.
B. In the lungs, oxygen is transported from the air to the blood through the process of diffusion.
In which molecules passively move from an area of high concentration to low concentration.
Specifically, the alveolar membranes withdraw the oxygen form the air in the lungs into the
bloodstream.
- Osmosis is the passive movement of a water from an area of low solute concentration to an area
of higher solute concentration through a permeable membrane.
- Reverse osmosis is the active transport of water opposite the concentration gradient from an
area of low solute concentration to high solute concentration.
- Dissipation is a more general reference of the spread or loss of energy.
Which gland is responsible for the regulation of calcium levels?
A. the parathyroid glands
,B. the pituitary gland
C. the adrenal glands
D. the pancreas
A. The parathyroid glands
The parathyroid glands are four small glands that isa on top of the thyroid gland and regulate
calcium levels by secreting parathyroid hormone.
The hormone regulates the amount of calcium and magnesium that is excreted by the kidneys
into the urine.
Which statement matches the function to the organ of the digestive system?
A. The large intestine reabsorbs water int he body to form solid waste.
B The duodenum is the middle section of the small intestine in which acids, fat, and sugar are
absorbed.
C. The jejunum is the first part of the small intestine that receives chyme form the stomach and
further digests it prior to entering the large intestine.
D. The gallbladder produces insulin to assist in the transport of sugars form the blood to the
organs.
A. The large intestine's main function is the reaborsptlon of water into the body to form solid
waste.
It also allows for the absorption of vitamin K produced by microbes living inside the large
intestine.
- The duodenum is the first second of the small intestine that receives partially digested food
from the stomach, also called chyme, further digestion tit with the help of enzymes released by
the gall bladder, before it enters into the small intestine.
- The pancreases (not the gall bladder) releases insulin to assist in the removal and transport of
sugar in the body.
,- The jejunum is the second portion of the small intestine in which amino acids, fatty acids, and
sugars are absorbed.
In your garden, you noticed that the tomato plants did better on the north side of your house than
the west side and you decided to figure out why. They are both planted with the same soil that
provides adequate nutrients to the plant, and they are watered at the same time during the week.
Over the course of a week, you begin to measure the amount of sunlight that hits each side of the
house and determine that the north side gets more light because the sunlight is blocked by the
house's shadow on the west side. What is the name of the factor in your observations that
affected the tomato plants growth?
A. the control
B. the independent variable
C. the dependent variable
D. The conclusion
B. The conclusion was that the amount of sunlight received by the pants was affecting their
growth.
- The independent variable was the amount of light that was given to the plants and could have
been manipulated by the experiment by moving the plants or adding equal parts of light.
- No control was used in this experiment.
Which of the following describes one responsibility of the integumentary system?
A. Distributing vital substances (such as nutrients) throughout the body
B. Blocking pathogens that cause disease
, C. Sending leaked fluids from cardiovascular system back to the blood vessels
D. sorting bodily hormones that influence gender traits.
B. The integumentary system includes skin, hair, and mucous membranes, all of which are
responsible-in part, at least-for blocking disease-causing pathogens from entering the
bloodstream.
- The circulatory system distributes vital substances through the body.
- The lymphatic system sends leaked fluids from the cardiovascular system back to the blood
vessels.
- The reproductive system stores bodily hormones that influence gender traits.
When are the parasympathetic nerves active within the nervous system?
A. when an individual experiences a strong emotion, such as fear or excitement.
B. when an individual feels pain or heat.
C. when an individual is either talking or walking.
D. when an individual is either resting or eating.
D. The parasympathetic nerves are active when an individual is ether resting or eating.
- The sympathetic nerves are active when an individual experience a strong emotion, such as fear
or excitement.
- Feeling pain and hat fall under the responsibility of the sensory neurons.
Talking and walking fall under the responsibility of the ganglia within the sensory-somatic
nervous system.
