Question 1:
Which of the following does NOT obey the law of independent assortment?
A. Two genes next to each other on a chromosome
B. Two genes on opposite ends of a chromosome
C. Flower color and height in snapdragons
D. Seed color and flower color in peas
The Correct Answer is A.Two genes next to each other (or within a specified close distance) are said to be linked. Linked genes do not follow the law of Independent assortment because they are too close together to be segregated from each other in meiosis.
Question 2:
What types of reaction is Cu (s) + 2AgNO3(aq) → 2Ag(s) + Cu(NO3)2(aq)?
A. Single replacement
B. Double replacement
C. Synthesis
D. Decomposition
The Correct Answer is A.This is a single replacement reaction in which copper replaces silver. The copper combines with the nitrate ions, and the silver precipitates out. Single replacement reactions have the general form of
A + BC →
AC + B. Double replacement reactions have the general form of AB + CD→
AD + CB. Synthesis reactions have the general form of A + B →
AB. Decomposition reactions have the general form AB→
A+B.
Question 3:
What is most likely the pH of a solution containing many hydroxide ions (OH-) and few hydrogen ions(H+)
A. 2
B. 6
C. 7
D. 9
The Correct Answer is D.A solution that contains more hydroxide ions than hydrogen ions is a base, and bases have a pH greater than 7, so the only possible answer is choice D. 9.
Question 4:
Given that there are over 100 million residential addresses in the United States, which of the following best describes a flaw of this survey as it is described?
A. There were not enough age groups to show a trend based on age.
B. The addresses were chosen randomly rather than strategically
C. The distribution of ages in the sample did not reflect the actual population
D. Each response represents only one person per address
The Correct Answer is A.While the random selection and large number of surveys sent out were a good start, to truly study the relationship between age and screen usage, it would have been better to have a few more age groups or just a direct age value from each participant rather than four large categories. As far as whether the age distribution accurately reflected the population, we don't have enough information to say if that was a problem or not. Also, the fact that each response is from just one person at the address is not a flaw but a reasonable way to get a good variety of responses
Question 5:
Which of the following anatomical terms is NOT part of the knee?
A. Medial collateral ligament
B. Patella
C. Lateral malleolus
D. Lateral meniscus
The Correct Answer is C.The term "lateral malleolus" refers to the bony prominence on the outer side of the ankle.
It is part of the ankle joint, not the knee joint. The other options, such as the medial collateral ligament, patella, and lateral meniscus, are all associated with the knee joint.
Question 6:
Which of the following statements concerning the states of matter is NOT true?
A. Plasmas are high-temperature collections of ions and free electrons.
B. Solids are the least compressible due to the more rigid positions of the particles.
C. Gases have no definite volume and expand to fill their containers
D. Liquids have no definite shape and no definite volume.
The Correct Answer is D.Liquids have no definite shape, but they do have a definite volume. While the particles of liquids move more freely than those in solids, they do maintain a definite volume.
Question 7:
How many different types of nucleotides are there in DNA?
A. One
B. Two
C. Four
D. Eight
The Correct Answer is C.There are four different nucleotides in DNA. Nucleotides are monomers of nucleic acids, composed of five- carbon sugars, a phosphate group, and a nitrogenous base. Nucleotides make up both DNA and RNA. They are essential for the recording of an organism's genetic information, which guides the actions of the various cells of the body.
Question 8:
Which of the following are formed when the plasma membrane surrounds a particle outside of the cell?
A. Golgi bodies
B. Rough endoplasmic reticulum
C. Secretory vesicles
D. Endocytic vesicles
The Correct Answer is D.Endocytosis is a process by which cells absorb larger molecules or even tiny organisms, such as bacteria, that would not be able to pass through the plasma membrane. Endocytic vesicles containing molecules from the extracellular environment often undergo further processing once they enter the cell.
Question 9:
A doctor needs to convince his boss to approve a test for a patient. Which statement below best communicates a scientific argument that justifies the need for the test?
A. The patient looks like he needs this test.
B. The doctor feels that the patient needs this test.
C. The patient's symptoms and health history suggest that this test will enable the correct diagnosis to help the patient.
D. The patient has excellent insurance that will pay for several tests, and the doctor would like to run as many tests as possible.
The Correct Answer is C.A scientific argument should be based on measurable and observable facts such as the patient's current symptoms and health history. Discussing the patient's appearance or the doctor's feelings does not communicate a scientific argument. While insurance may be a factor in most healthcare systems, the status of the patient's Insurance does not communicate a scientific argument that justifies the need for the test
Question 10:
Which of the following is true regarding adipocytes?
A. They are involved in the secretion of glucose.
B. They are responsible for storing the fat that is found in adipose tissue
C. They are critical in the digestive breakdown of fat
D. They are the foundational element of muscles
The Correct Answer is B.Adipocytes are primarily seen in adipose or fat tissue. Their primary function is the storage of fat Adipocytes play a crucial role in maintaining proper energy balance, storing calories in the form of lipids, and mobilizing energy sources in response to stress. They are not involved in the digestion of fat or the secretion of glucose, nor are they the foundational element of muscles
