Which of the following statements is true? In all cells, the plasma membrane controls what enters and exits. Eukaryotic cells don't have a nucleus but often have a flagella. All cells are made up o... f smaller cells. Prokaryotic cells don't have a nucleus, but they still have a plasma membrane that separates their DNA from their cytoplasm. CONCEPT Cell Theory 2 Which statement about active transport is true? It does not require transport proteins. 7/29/2020 Sophia :: Welcome https://www.sophia.org/spcc/human-biology-2/milestone_take_feedbacks/5345409 2/11 It involves the use of DNA. It involves smaller molecules only. It requires ATP molecules. CONCEPT Facilitated Diffusion 3 Which of the following statements about enzymes is true? The substrate will be physically different, but not chemically different after being acted upon by an enzyme. Any enzyme in your body is capable of taking part in any type of reaction. Enzymes most often help to slow down reactions in the body. An enzyme can act to either join substrates together or break them down. CONCEPT Enzymes 4 Which of the following is carried out by vesicles? Synthesizing proteins Organizing organelles prior to division Facilitated diffusion 7/29/2020 Sophia :: Welcome https://www.sophia.org/spcc/human-biology-2/milestone_take_feedbacks/5345409 3/11 Breaking down substances within the cell CONCEPT Golgi Body 5 Which of the following sources of information is most credible? A lecture given by a biology teacher on the first day of class A high school biology textbook written and reviewed by a team of biology professors Medical advice given by a nursing intern during an appointment An unbacked statement from a trusted friend CONCEPT Evaluate Information 6 Which of the following statements is true? Diffusion is the movement of molecules across a plasma membrane, regardless of concentration gradient. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Diffusion requires ATP to function. Diffusion is the movement of molecules from an area of low concentration to an area of high concentration. CONCEPT [Show More]
