a.
b.
c.
d.
Sound
Light
Scent
Touch
Correct Answer: Light
Reasoning:
Eyes respond to light. The darker the light the larger the pupil will be. This is so you can absorb
whatever light is available to be able to see. Many other parts of your body respond to stimuli.
Your stomach “growls” when it is empty. Your feet tingle when you restrict blood flow.

means that the person
a.
b.
c.
d.
Does not need tissues
Does not need organs
Is multi cellular
Is unicellular
Correct Answer: C
Reasoning: 200 plus different kinds of cells is describing a multi cellular organism. You can
conclude this by the fact that there are more than 2 cells. It also states that they have
specialized jobs.
New Question:

Old Question
12. Fully grown adults are much larger in size than young children. What happens to the cells of
the body during the growth of a child?
a. The cells of a growing child divide to make more cells and those cells are each
half the size as the cells were before they divided. The cells do not grow before
they divide again.
b. The cells of a growing child divide to make more cells, and those cells grow to
become the same size as the cells were just before they divided.
c. The cells of the body of a growing child grow, but the number of cells stays the
same.
d. The size and number of cells in the body of a growing child stay the same.
Correct answer- B
Reasoning: As a cell divides it always grows until it is the size of the original cell and then it
divides again. Cells are constantly dividing to make new cells.
New Question
12.True or false- As you grow up your cells grow and get larger?
Old Question

Because it is the most general
Old Question
15. Use the dichotomous key to classify the organism below.
a. Phoca vitulina
b. Cystophora cristata
c. Pusa hispida
d. Halichoerus grypus
Correct answer: C
Reasoning: The organism has dark colored body with light spots so you go to step 3. The
organism has a dark colored body marked with light colored pale rings so it is a Pusa hispida.
With a dichotomous key you always start at the top of the key and follow the directions down
the key.
