A
,A 6kg box is placed on a surface. Two students investigate how different types of forces
can affect its motion. The text box shows the steps for the investigation.
1. Two students push the box for 5 min in the same direction.
2. A student pushes the box for 5 min in one direction.
3. Note the distance the mod moves when two students push the box.
4. Compare the distance the box moved each time.
5. Identify in which case the box moved faster.
6. Note the distance the box moves when one student pushes the box.
Which of the following should be the correct sequence of the steps? - Answer-A)
1,6,5,4,3,2
B) 6,3,2,1,5,4
C) 2,6,1,3,4,5
D) 4,6,2,5,3,1
C
Which of the following structures is directly stimulated by messages from the
hypothalamus? - Answer-A) spinal cord
B) Pancreas
C) Gonads
D) Pituitary gland
D
Which of the following explains the relationship between chromosomes and genes? -
Answer-A) Several chromosomes makeup one strand of a gene.
B) Many genes can be found on a single chromosome.
C) Chromosomes and genes are similar in length, but one expresses a protein and one

B
The disassociation of hydrogen molecules into hydrogen atoms is a reversible reaction.
The equilibrium constant of the reaction is 10^(-36) at 25 and 6x10^(-5) at 5,000?
Which of the following statements is true about equilibrium at two temperatures? -
Answer-A) Most of the hydrogen gas is undissociated at 5,000° C, and the equilibrium
lies towards the reactants.
B) Most of the hydrogen gas is disassociated at 25° C, and the equilibrium lies towards
the products.
C) Most of the hydrogen gas is disassociated at 5,000° C, and the equilibrium lies
towards the products.
D) Most of the hydrogen gas is undissociated at 25° C, and the equilibrium lies towards
the products.
,C- The value of the equilibrium constant is high at temperature 5,000° C. Therefore,
most of the reactants convert into products at that temperature, and the equilibrium lies
toward the products.
Which of the following options distinguishes the active and passive transport
mechanisms? - Answer-A) Active transport: Lower to Higher concentration; Passive
transport: Higher to lower concentration
B) Active transport: Lower to Higher concentration; Passive transport: Higher to lower
concentration
C) Active transport: Higher to Lower concentration; Passive transport: Higher to lower
concentration
D) Active transport: Higher to lower concentration; Passive transport: Lower to Higher
concentration
A- Active and passive transports are tow different types of transport mechanisms. Active
transport allows the movement of molecules from a.region of lower to a region of higher
concentration. However, passive transport involves the movement of molecules from
higher to lower concentrations region.

Mouth
B) Stomach
C) Liver
D) Large intestine
D
Lung cancer is found more often in people who have a history of smoking. Scientists
believe this is because lung cells are damaged over time. Which of the following pieces
of evidence supports the explanation? - Answer-A) A group of non smokers are studied
and have the same rates of lung cancer as do those with smoking backgrounds
B) Studies have found that smoking can cause other life-threatening conditions, such as
chronic bronchitis and emphysema
C) Chemicals found in cigarettes have shown to damage part of cells that can lead to
cancer
D) 87% of lung cancer deaths are due to smoking
C
Which of the following is the enzyme in tears that destroys microorganisms? - Answer-
A) Granzyme
B) Lysozyme
C) Pyrogen
D) Cytokine
B

fibers of the atria to contract? - Answer-A) Sinoatrial node
B) Arteries
C) Atrioventricular node
D) Veins
A

human body
D) It gives a standard point of reference for describing anatomical positions and terms
of the human body

fullness
B) Stimulates the uptake of glucose by cells
C) Stimulates the breakdown of glycogen
D) Digests protein
