When Nora's white blood cells engulf bacteria to protect her body, this is an example of which type of transport process?

• Active process

• Passive process

• Facilitated diffusion

• Simple diffusion

Abigail is learning about how her body gets energy to run and play. She wonders which organelles in her cells make most of the ATP that powers her activities. Which organelles are responsible for this?

• Mitochondria

• Ribosomes

• Lysosomes

• Golgi apparatus

James is organizing a relay race where each runner represents a phase of mitosis. To ensure the race follows the correct biological sequence, in what order should James assign the runners to represent the phases?

• Prophase (Interphase), Metaphase, Anaphase, Telophase

• Metaphase, Prophase, Telophase, Anaphase (Interphase)

• Anaphase, Telophase, Prophase (Interphase), Metaphase

• Telophase, Anaphase, Metaphase, Prophase (Interphase)

Emma is studying the microscopic structure of animal tissues in her biology class. Which of the following best defines what Emma is studying (Histology)?

• The study of of tissues.

• The study of plant biology.

• The study of chemical reactions in cells.

• The study of the microscopic structure of tissues.

The level of Ca2+ ions in the blood must be carefully regulated. Cells in the parathyroid gland monitor the Ca2+ level. If the Ca2+ level decreases, the parathyroid glands are stimulated to start producing more PTH, a hormone. When parathyroid hormone levels are elevated, the kidneys will increase the amount of Ca2+ returned to the blood during the urine-making process. This results in an increase of Ca2+ in the blood. The effector is:

• kidneys

• parathyroid glands

Maya is in charge of security at a museum. She installs a special door that only lets certain people with the right badge enter, while others are not allowed in. What does this situation best illustrate?

• Selective permeability is the ability of a membrane to allow certain substances to pass while restricting others.

• Selective permeability is the capacity of a membrane to block all substances from entering.

• Selective permeability refers to the ability of a membrane to absorb all types of molecules.

• Selective permeability is the process of allowing all substances to pass freely.

Nora is studying human anatomy and wants to identify the type of tissue in different parts of the body. She examines: a. The spinal cord b. The lining of the larynx c. The biceps muscle. Which types of tissue make up these structures?

• a. Nervous tissue, b. Epithelial tissue, c. Muscular tissue

• a. Muscular tissue, b. Connective tissue, c. Nervous tissue

• a. Epithelial tissue, b. Muscular tissue, c. Connective tissue

• a. Connective tissue, b. Nervous tissue, c. Epithelial tissue

The level of Ca2+ ions in the blood must be carefully regulated. Cells in the parathyroid gland monitor the Ca2+ level. If the Ca2+ level decreases, the parathyroid glands are stimulated to start producing more PTH, a hormone. When parathyroid hormone levels are elevated, the kidneys will increase the amount of Ca2+ returned to the blood during the urine-making process. This results in an increase of Ca2+ in the blood. The control center is:

• kidneys

• parathyroid glands

Hannah is studying how cells take in nutrients from their surroundings. She learns that cells can internalize substances by engulfing them in a vesicle. What is this process called?

• Endocytosis is the process by which cells internalize substances by engulfing them in a vesicle.

• Endocytosis is the method by which cells produce energy.

• Endocytosis refers to the release of substances from a cell.

• Endocytosis is the process of cell division.

• Positive-feedback

• Negative-feedback
