1. What is the scientific study of the relationships between organisms and their environment?

Correct answer: C

Rationale: Ecology is the scientific study of the relationships between organisms and their environment, including the interactions between living organisms and their physical surroundings. This field focuses on how organisms interact with each other and their environment. Zoology is the study of animals, Botany is the study of plants, and Genetics is the study of genes and heredity, which are not directly related to the relationships between organisms and their environment. Therefore, the correct answer is Ecology as it specifically deals with the interactions between living organisms and their environment.

2. Which of the following describes the difference between prokaryotic and eukaryotic cells?

Correct answer: D

Rationale: Eukaryotic cells have a true nucleus that contains the genetic material, while prokaryotic cells lack a true nucleus. Eukaryotic cells also have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which are absent in prokaryotic cells.

3. If a patient had a heart attack and tissue in the left ventricle lost blood flow, what would you most expect to happen?

Correct answer: C

Rationale: The correct answer is C: 'Blood would not be pumped to the body.' When tissue in the left ventricle loses blood flow due to a heart attack, the ability of the left ventricle to pump oxygenated blood to the body is compromised. This can lead to serious consequences for the patient's overall health and organ function. Choices A, B, and D are incorrect because a heart attack affecting the left ventricle does not directly impact blood flow from the lungs, cause blood to back up in the legs, or prevent blood from being oxygenated. The primary concern is the compromised ability of the left ventricle to pump blood to the rest of the body, affecting overall circulation and organ perfusion.

4. Which term describes the resistance of a substance to being hammered into different shapes?

Correct answer: C

Rationale: Malleability is the property that allows a substance to be hammered or rolled into thin sheets without breaking. It is the opposite of brittleness. Ductility refers to the ability of a material to be drawn into thin wires, not hammered into shapes. Viscosity is the measure of a fluid's resistance to flow, indicating how thick or sticky it is, not related to shaping by hammering. Conductivity refers to the ability of a material to conduct electricity or heat, not resistance to being hammered into different shapes.

5. Which muscle type is characterized by a combination of voluntary and involuntary control, is striated, and is responsible for pumping blood throughout the circulatory system?

Correct answer: C

Rationale: The correct answer is C, Cardiac muscle. Cardiac muscle is characterized by a combination of voluntary and involuntary control, is striated, and is responsible for pumping blood throughout the circulatory system. Skeletal muscle is primarily under voluntary control, smooth muscle is primarily under involuntary control, and connective tissue is not a muscle type, but rather provides support and structure to the body.
