Science TEAS Practice Test

1. What is the smallest unit that can encode for a trait?

Correct answer: B

Rationale: The correct answer is B - a gene. Genes are the smallest units that can encode for a trait as they contain the specific instructions for producing a particular characteristic or protein. While codons are sequences of nucleotides that code for specific amino acids in a protein, they are not the smallest unit that encodes for a trait. Nucleotides are the building blocks of DNA and RNA, and chromosomes are made up of DNA and proteins, containing many genes.

2. Which of the following is not a type of muscle tissue?

Correct answer: D

Rationale: The correct answer is D, Adipose. Adipose tissue is a type of connective tissue that stores fat, not muscle tissue. Skeletal, smooth, and cardiac are all types of muscle tissues found in the body. Skeletal muscle tissue is responsible for voluntary movements and is attached to bones. Smooth muscle tissue is found in the walls of hollow organs and blood vessels, responsible for involuntary movements. Cardiac muscle tissue is found in the heart and is responsible for pumping blood throughout the body. Adipose tissue, on the other hand, primarily functions as a storage site for energy in the form of fat.

3. Which of the following is NOT one of the major types of bones in the human body?

Correct answer: A

Rationale: The correct answer is A: 'Dense bone'. Dense bone is not a classification of bone types in the human body. The major types of bones include long, short, flat, and irregular bones. Long bones, like the femur, are characterized by being longer than they are wide. Short bones, such as those in the wrist (carpals) and ankle (tarsals), are generally cube-shaped. Flat bones, like the skull or scapula, are thin and provide protection. Irregular bones, such as the vertebrae, have complex shapes that do not fit into the other categories.

4. Which of the following structures connects muscle to bone?

Correct answer: B

Rationale: Tendons are the correct answer as they are fibrous structures that connect muscle to bone, enabling the transmission of force during movement. Ligaments, on the contrary, connect bone to bone, aiding in joint stability. Muscles contract to generate force and facilitate movement, while bones provide structural support and protect internal organs.

5. Which of the following is a representation of a natural pattern or occurrence that is difficult or impossible to experience directly?

Correct answer: B

Rationale: A model is a representation used by scientists to understand and explain natural phenomena that are challenging or impossible to observe directly. Models help visualize complex systems or processes that are not easily accessible for direct observation. The other choices are incorrect because: A) A theory is an explanation or interpretation of observable facts or phenomena. C) A law describes a consistent and universal phenomenon or relationship in nature based on repeated observations. D) An observation is a direct act of watching or taking note of a phenomenon or behavior.
