Question 1:
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 2:
Escherichia cell is plated on nutrient agar plates that each contain a different type of antibiotic. The shaded area represents growth of the bacteria. Which of the following plates contains bacteria that were most resistant to the antibiotic
A. A
B. B
C. C
D. D
The Correct Answer is C.This is the plate with the most growth despite the presence of antibiotic cover.
Question 3:
Which of the following demonstrates a chemical reaction of water?
A. Water boils to produce steam at 100° C (252)
B. Water Dissolves sugar
C. Water produces gas with sodium metal
D. Water and all separate when combined
The Correct Answer is C.a. Water boils to produce steam at 100°C - This is a phase change (from liquid to gas) and not a chemical reaction of water.
b. Water dissolves sugar - This is a physical change, not a chemical reaction of water.
c. Water produces gas with sodium metal - This reaction involves the chemical reaction of water with sodium metal to produce hydrogen gas.
d. Water and oil separate when combined - This is a physical separation, not a chemical reaction of water.

Question 5:
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 6:
Which of the following hormones regulates blood calcium levels?
A. Parathyroid hormone
B. Growth hormone
C. Norepinephrine
D. Melatonin
The Correct Answer is A.The parathyroid hormone (PTH) from the parathyroid glands is important in serum calcium regulation. It increases blood calcium levels by stimulating osteoclasts to break down bone and release calcium into the bloodstream. PTH also enhances the absorption of calcium from the intestines and the kidneys.
Question 7:
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 8:
Which of the following correctly orders structures from simple to complex?
A. Organs, tissues, cells, atoms
B. Cell, tissues, atoms, organs
C. Atoms, organs, tissues, cells
D. Atoms, cells, tissues, organs
The Correct Answer is D.Rationale
Atoms are the smallest and most basic units of matter, and they can combine to form molecules. Cells are the basic units of life, and they are made of molecules. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue or nerve tissue. Organs are collections of tissues that form a larger structure.
Question 9:
in which of the following locations does fertilization of an egg cell typically occur?
A. Fallopian Tube
B. Ovary
C. Uterus
D. Cervical canal
The Correct Answer is A.Fertilization occurs in the fallopian tube and not in the ovary, uterus, or cervical canal.
Question 10:
Which of the following characteristics of water helps explain why coastal areas experience less dramatic temperature changes during the day?
A. Water has a high specific heat capacity
B. Water is a versatile solvent
C. Water forms covalent bonds with other water molecules
D. Water's adhesive properties prevent evaporation
The Correct Answer is A.Water has a high specific heat capacity, which means it can absorb and store a large amount of heat energy without significantly changing in temperature. This helps moderate the temperature fluctuations of the air near the coast, as water can store heat during the day and release it at night, or vice versa.
