Which of the following statements is FALSE?

A. An organelle is a specialized structure in a cell, such as a ribosome.

B. An organ is made up of similar tissues that perform the same function.

C. Organ systems are two or more organs performing similar functions.

D. A tissue contains a single cell type that works to perform a specific function.

Answer Explanation:

A tissue contains a variety of cell types that work in conjunction to perform similar functions.

The cells are similar in structure despite being located throughout the body. There are four types of tissues in the human body: connective, epithelial, muscle, and nervous system tissues.

Therefore, the Correct Answer is D.

Q #1: Which of the following is true regarding adipocytes?

A. They are involved in the secretion of glucose.

B. They are responsible for storing the fat that is found in adipose tissue

C. They are critical in the digestive breakdown of fat

D. They are the foundational element of muscles

Answer Explanation

Adipocytes are primarily seen in adipose or fat tissue. Their primary function is the storage of fat Adipocytes play a crucial role in maintaining proper energy balance, storing calories in the form of lipids, and mobilizing energy sources in response to stress. They are not involved in the digestion of fat or the secretion of glucose, nor are they the foundational element of muscles
Q #2: Which structure of the nervous system carries action potential in the direction of a synapse?

A. Cell body

B. Axon

C. Neuron

D. Myelin

Answer Explanation

Axons carry action potential in the direction of synapses. Axons are the long, fiber-like structures that carry information from neurons. Electrical impulses travel along the body of the axons, some of which are up to a foot long.

A neuron is a type of cell that is responsible for sending information throughout the body. There are several types of neurons, including muscle neurons, which respond to instructions for movement; sensory neurons, which transmit information about the external world; and interneurons, which relay messages between neurons. Myelin is a fat that coats the nerves and ensures the accurate transmission of information in the nervous system.
Q #3: Which of the following molecules exhibits ionic bonding?

A. NaCl

B. CO2

C. C6H12O6

D. H2O

Answer Explanation

Sodium chloride exhibits lonic bonding due to the attraction between Na+ ions and Cl- ions.

Typically, elements on the opposite sides of the periodic table (a metal and a nonmetal) form ionic bonds. Carbon dioxide, water, and glucose exhibit covalent bonding. Typically, elements on the same side of the periodic table (two or more nonmetals) form covalent bonds.
