Among the choices provided, only one process is directly influenced by atmospheric pressure:
Pulmonary Ventilation (Correct): Pulmonary ventilation, also known as breathing, is driven by pressure differences between the lungs and the atmosphere. Atmospheric pressure plays a pivotal role in this process by facilitating the movement of air into and out of the lungs.
The other options mentioned in the choices—Photosynthesis, Osmosis, and Evaporation—are not primarily influenced by atmospheric pressure. While atmospheric pressure can indirectly affect certain aspects of these processes, it is not a dominant factor in their mechanisms.
Therefore, the Correct Answer is A.

Question 1:
Which of the following is the atomic number of an atom that has 12 protons and 12 neutrons?
A. 144
B. 12
C. 24
D. 1
The Correct Answer is B.elements are arranged on the periodic table based on their atomic number. This identity is critical in evaluating the chemical families of elements in chemistry. Atoms are made of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus while electrons are found outside the nucleus of the atom. It is the number of protons of an atom that gives its atomic number. Therefore, an atom with 12 protons has an atomic number of 12.
Question 2:
A myocardial infarction affects which of the following blood vessels of the heart?
A. Aorta
B. Vena cava
C. Pulmonary
D. Coronary
The Correct Answer is D.A myocardial infarction refers to heart attack, which result from blockage of blood flowing into the heart.
Blocking is caused by the deposition of fat or cholesterol that forms plaque on the surface of coronary arteries, which supply blood to the heart.
Question 3:
Which of the following are structural features of the trachea?
A. C-shaped cartilage
B. Smooth muscle fibers
C. Cilia
D. All of the above
The Correct Answer is A.Question 4:
The Life Cycle of HIV
Which of the following allows the AIDS virus, which contains RNA, to insert viral DNA into the DNA of a host T-cell after the AIDS virus enters the cell?
A. Receptor proteins located on the surface of the virus
B. The protein that makes up the capsid of the virus
C. Reverse transcriptase, an enzyme encoded by the virus
D. The phospholipids found on the envelope of the virus
The Correct Answer is C.The AIDS virus (HIV virus) is Class VI or Group VI in the Baltimore Classification. Based on the Baltimore Classification, this specifically involves the reverse transcriptase enzyme and it is encoded by the virus.
This is the enzyme that will produce DNA molecules from the viral RNA. This is the mechanism involved where it will use the reverse transcriptase enzyme to insert viral DNA into the genetic material of the host cell.

Practice Question
An atom has 14 protons and 20 neutrons. What is its atomic number?
A. 20
B. 17
C. 10
D. 14
The Correct Answer is D.Question 6:
Punnett squares are used by geneticists to determine the probability of different offspring genotypes. In the one shown below, what letter(s) belong in the lower right box?
A. AA
B. Aa
C. aA
D. aa
The Correct Answer is D.From the given Punnett square, we can cross the genotypes of the two parents and established the phenotypes the offspring will have. The Punnett square is filled as:
|
|
A |
a |
|
a |
Aa |
aa |
|
a |
Aa |
aa |
The requested answer is aa.
Question 7:
An atom of lead (Pb) has a mass number of 207. How many neutrons are in the nucleus?
A. 130
B. 125
C. 82
D. 84
The Correct Answer is B.We find the number of neutrons as follows
Number of neutrons
= mass number – atomic number
= 207 – 82
= 125 neutrons
Question 8:
Which of the following best describes the result of using a catalyst in a chemical reaction?
A. A more desirable product is often formed
B. The reaction is completed in a shorter amount of time
C. The yield of product is increased
D. A greater amount of energy is released by the reaction
The Correct Answer is B.A catalyst is substance that speeds up the rate of converting reactants to products. They do by decreasing the activation energy of a reaction. If a catalyst increases the rate of reaction, then it means that the reaction takes a smaller time to come into completion.
Catalysts can be metals, ions or biological also known as enzymes. Catalysts are not consumed when the reaction is taking place.
Question 9:
Lithium has an atomic number of 3 and a mass number of 7.
Which of the following is the number of neutrons in a lithium atom?
A. 4
B. 7
C. 12
D. 3
The Correct Answer is A.The atom is identified by the atomic number in the periodic table. The atomic number is equal to the number of protons and mass number is the sum of the number of protons and neutrons in the nucleus of an atom. Thus, to find how many neutrons are in lithium atom we use the formula below.
Mass number = number of protons + number of neutrons.
Letting n be number of neutrons in the lithium atom, we have
7=3+n
Rearranging the above equation
3+n=7
n=7-3
n=4
Thus, lithium atom has 4 neutrons.
Question 10:
Punnett square
In a certain plant, red flowers are dominant over white flowers. A plant heterozygous for red flowers and a plant with white flowers are crossed. Which of the following is the expected proportion of phenotypes in the next generation?
A. 4 red, 0 white
B. 2 red, 2 white
C. 1 red, 3 white
D. 3 red, 1 white
The Correct Answer is B.We use the Punnet square to find the population of the resulting offspring from the crossing of a plant heterozygous for red flowers with a plant with white flowers.
Let R be the dominant allele for red while r is the recessive allele color for red. Therefore, the phenotype for parent 1 which is heterozygous for red flower will be Rr and the second parent with white flowers will be rr.
We cross the two phenotypes in a Punnet square as follows
|
|
r |
r |
|
R |
Rr |
Rr |
|
r |
rr |
rr |
Thus, there are 2 heterozygous offspring with red flowers and 2 offspring with white flowers.
