Question 1:
A represents atomic mass and 2 represents an atomic number, which of the following describes an atom after a proton is emitted?
A. A-1,2-1
B. A-1,2+1
C. A,2-1
D. A+1,2-1
The Correct Answer is A.This is because when a proton is emitted from an atom, the atomic mass decreases by one unit, and the atomic number decreases by one unit. The atomic mass is the sum of protons and neutrons in the nucleus, and the atomic number is the number of protons in the nucleus. Therefore, if a proton is lost, both numbers decrease by one.
Question 2:
Using the equation PH = -log (H+), a solution with a (H+)= 10+ M has a PH of which of the following?
A. 9
B. 5
C. 1
D. 10
The Correct Answer is C.Concentration of H+ in the solution = 10 −1 M
pH= -log(10 −1)
pH= -(-1)
=1
Question 3:
The "gray matter of the brain is largely made up of which of the following?
A. Neuron cell bodies
B. Meninges
C. Neuron cell axons
D. Corpus callosum
The Correct Answer is A.The gray matter of the brain primarily consists of neuron cell bodies, along with dendrites, glial cells, and unmyelinated axons. It appears gray because it lacks the white fatty myelin sheath that covers many nerve fibers.
Question 4:
Which of the following structures is present in both prokaryotic and eukaryotic cells
A. Chloroplast
B. Cell membrane
C. Golgi apparatus
D. Endoplasmic reticulum
The Correct Answer is B.Both prokaryotic and eukaryotic cells have a cell membrane. The cell membrane is a barrier that surrounds the cell and separates its internal environment from the external environment.
Question 5:
A slice of apple left on a table slowly goes brown due to an enzymatic reaction. Dipping the apple slice in lemon juice prevents it from browning Which of the following best explains this result?
A. Lemon juice has enzymes which reverse the browning reaction
B. Lemon juice has a pH which inactivates the enzymes
C. Lemon juice functions to bleach the brown material
D. Lemon juice functions to dilute the brown material
The Correct Answer is B.Browning of the apple surface is due to the action of the enzyme polyphenol oxidase. Lemon juice is acidic and lowers the pH of the apple's surface. This inactivates the enzyme polyphenol oxidase, which works best at a neutral pH. This in turn reduces the browning action on the apple.
Question 6:
Which structure of the female reproductive system is the source of the blood and mucosal tissue during menstruation? (You will find hot spots to
Select in the image below. Select only the hot spot that corresponds to your answer.
A.
B.
C.
D.
The Correct Answer is B.The inner lining of the uterus is the source of blood and mucosal tissue that is shed during menstruation.
Question 7:
Which of the following is the term given to the sequence of nucleotides that contains the information to make a specific protein molecule?
A. Locus
B. Promoter
C. Operator
D. Gene
The Correct Answer is D.A gene is a segment of DNA that codes for a specific protein or polypeptide.
Question 8:
Parasitic worm infestation is hypothesized to be damaging to the host. However, scientists have recently discovered that worm infestation can relieve the effects of certain autoimmune disorders, in which of the following ways should the hypothesis be modified, given the new findings?
A. Lack of worm infestations is the cause of some autoimmune disorders.
B. Worm infestation reduces the severity of certain autoimmune disorders
C. Worm infestation prevents the body from immune malfunction
D. Worm infestations exacerbate the body's immune reactions
The Correct Answer is B.The new findings can be used to generate a hypothesis to reflect the beneficial aspect of worm infestations in certain autoimmune disorders, indicating that they can help reduce the severity of the condition.
Question 9:
Which of the following cells transfers pigment granules to adjacent epidermal cells?
A. Melanocytes
B. Merkel cells
C. Langerhans cells
D. Keratinocytes
The Correct Answer is A.Melanocytes are specialized skin cells that produce melanin, which is the protective skin-darkening pigment. They are found mainly in the epidermis, though they occur elsewhere, such as in the hair.
Question 10:
Which of the following tools can be used to measure the turbidity of a liquid by measuring the transmission of light through the sample?
A. Spectrophotometer
B. Centrifuge
C. Electro photometer
D. Microdensitometer
The Correct Answer is A.A spectrophotometer is an instrument that measures the intensity of light absorbed after it passes through a sample solution. With the spectrophotometer, the concentration of a chemical substance can be determined by measuring the intensity of light detected.
