Science Practice Questions for CSET Multiple Subjects Subtest II

If you're preparing for the CSET multiple subjects subtest two, science life science exam, this video is designed to make studying clear and more manageable. Hi, I'm Selena, teacher with over 20 years of classroom experience and test prep expert with study.com. In this lesson, we will work through competency based sample questions covering key life science concepts like cell structure and function, energy flow, ecosystems and evolution while practicing smart test taking strategies so you can confidently choose the best answer on exam day. Stick around to the end to learn more information about the exam. Let's dive in. Question one, which of the following organelles is primarily responsible for generating ATP, the main energy currency of the cell? ribosome, endoplasmic reticulum, mitochondrion, or Golgi apparatus. Let's walk through the process of elimination. is incorrect. Ribosomes are responsible for protein synthesis. is incorrect. The endoplasmic reticulum is involved in protein and lipid synthesis and transport. is incorrect. The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. The correct answer is mitochondrion. Mitochondria are often referred to as the powerhouses of the cell because they carry out cellular respiration, process that converts glucose and oxygen into ATP. Which of the following describes biotic factor in an ecosystem? population of deer, the amount of rainfall the temperature range or the mineral composition of the soil. is incorrect. Rainfall is an abiotic factor, non-living physical or chemical component of an ecosystem. is incorrect. Temperature is also an abiotic factor, physical condition of the environment. is incorrect. The mineral composition of the soil. Soil composition is an abiotic factor, non-living chemical aspect of the environment. The correct answer is population of deer is group of living organisms. Biotic factors are the living components of an ecosystem, including plants, animals, fungi, bacteria, and protists. The process by which individuals with advantageous traits are more likely to survive and reproduce leading to the accumulation of these traits in subsequent generations is known as genetic drift gene flow natural selection or mutation. is incorrect. Genetic drift is the random fluctuation of allele frequencies in population from one generation to the next especially in small populations. is incorrect. Gene flow is the movement of genes into or out of population due to the migration of individuals. is incorrect. Mutation is change in the DNA sequence, which can introduce new traits. But it is the process of natural selection that determines which traits become more common. The correct answer is Natural selection is the core mechanism of evolution proposed by Charles Darwin. It favors individuals with heritable traits that enhance their survival and reproductive success in particular environment. Which of the following is the primary function of the cell membrane? to synthesize proteins. to store the cell's genetic material. to generate energy through cellular respiration. Or to regulate the passage of substances into and out of the cell. is incorrect. Protein synthesis occurs in ribosomes. is incorrect. The cell's genetic material is primarily stored in the nucleus. is incorrect. Energy generation primarily occurs in the mitochondria and the cytoplasm and cell membrane. The correct answer is The cell membrane is selectively permeable barrier that controls which molecules and ions can enter or leave the cell, maintaining the cell's internal environment. Let's take closer look at what the CSET Multiple Subjects Subtest 2 Science Life Science exam is really measuring. This part of the test measures your understanding of foundational life science concepts, including cell structure and function, energy transfer, ecosystems, and the mechanisms of evolution. In the practice questions, you apply your knowledge of organelles, biotic and abiotic factors, natural selection, and cell membranes. The goal isn't just to memorize biology terms, it's to understand how life science concepts connect, and apply that understanding to analyze questions, eliminate incorrect choices, and confidently select the best answer on test day.
