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

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
Correct Answers - B. The conclusion was that the amount of sunlight received by the
pants was affecting their growth.
Rationale;
- 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.

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.
Correct Answers - 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.
Rationale;
- 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.

and the integumentary system?
A. removal of excess heat from body.
B. hormonal influence on blood pressure
C. regulation of blood's pressure and volume.
D. development of blood cells within marrow.
Correct Answers - A.
Rationale;
The integumentary system coordinates with the circulatory system to remove excess
heat form the body. The superficial blood vessels (those nearest the surface of the skin)
dilate to allow the heat to exit the Boyd.
- The hormonal influence on blood pressure is the result of the relationship between the
circulatory system and the endocrine system.
- The urinary system is responsible for assisting the regulation of blood's pressure and
volume.
- The skeletal system is responsible for assisting the development of blood vessels
within the marrow.
Which of the following statements describes the path of blood entering into the heart?
A. Blood enters the heart through the pulmonary vein, into the right atrium, through the
tricuspid have to the right ventricle.
B. Once the right ventricle is full, blood exits into the pulmonary artery and then empties
into the left ventricle.
C. After traveling through he lungs, oxygenated blood enters into the left atrium, then
through the mitral valve to the left ventricle.
D. Once the left ventricle is full, the left tricuspid valve shuts, the ventricle contracts, and
blood exists through the aorta.
Correct Answers - C.
