Question 1
What is the basic functional unit of all living organisms?
Correct Answer:
Cell
Explanation:
Life centers on the cell. It is the smallest unit that can carry out all the processes that keep an organism alive—taking in nutrients, converting energy, eliminating wastes, growing, responding to the environment, and even reproducing. Cells come with the components needed to perform these functions, and in many organisms they contain DNA that guides those activities. Some cells have a nucleus that houses genetic material, while others do not, but either way the cell itself is the basic unit that carries out life processes. Tissues and organs are higher levels of organization built from many cells, not the fundamental unit. So the cell is the smallest unit that can function independently to sustain life across all organisms.
Question 2
Meiosis results in four haploid gametes from a single diploid cell. Which sequence of options places Meiosis last?
Correct Answer:
Meiosis
Explanation:
Meiosis is the final step in a sequence that ends with forming haploid gametes. It specifically reduces chromosome number and yields four haploid cells, which is why it sits at the end of the process for producing gametes from a diploid cell. Binary fission is how many bacteria reproduce and doesn’t produce haploid gametes. Cytokinesis is the division of the cytoplasm that follows mitosis to create two cells, and mitosis is the division that separates replicated chromosomes into two nuclei before that cytoplasm splits. So meiosis is the last step in this sequence because it completes the production of haploid gametes.
Question 3
Which force is exerted on an object in contact with another stable object?
Correct Answer:
Normal force
Explanation:
When two objects touch, they push on each other through a contact force. The part of that force that acts perpendicular to the surfaces at the point of contact is the normal force. It provides support and prevents the objects from interpenetrating, adjusting in magnitude as needed to balance other perpendicular forces like gravity. Tension is the force carried by a rope or string, acting along the rope, not as a surface contact force. Kinetic energy is not a force at all. While “contact forces” is a broad category that includes the normal force, the specific force exerted in contact between surfaces is the normal force.
Question 4
What term describes the lowest possible temperature at which particles have minimal motion?
Correct Answer:
Absolute zero
Explanation:
At the lowest possible temperature, particle motion is minimized. This limit is absolute zero, defined as zero kelvin (about −273.15°C). In theory, reaching absolute zero would stop a substance’s thermal motion, but quantum mechanics means particles retain some zero-point energy and can’t be completely at rest. This makes absolute zero the boundary value for how cold matter can get. Normal room temperature is much warmer and involves noticeable molecular motion. Thermal energy is the energy associated with temperature, not a temperature itself. Boiling point is the temperature at which a liquid changes to a gas.
Question 5
Which term refers to elements that react easily with other substances, are poor conductors, readily accept electrons, and are gaseous at room temperature?
Correct Answer:
Nonmetals
Explanation:
Elements that tend to react with many substances, don’t conduct electricity well, readily accept electrons, and are often gases at room temperature are nonmetals. Nonmetals typically have high electronegativity and electron affinity, so they gain electrons in reactions to form negative ions or share electrons in covalent bonds. Their lack of metallic bonding means they don’t have free-moving electrons, which makes them poor conductors of heat and electricity. At room temperature, many nonmetals exist as gases—like oxygen and nitrogen—while others are liquids or solids, showing a broad range of states but a common behavior: they are reactive, electron-hungry partners in compounds and generally poor conductors.
