Question

match the vocabulary term to its definition.
definition

• a protein that can cause infection or disease
• nonliving strand of genetic material that cannot replicate on its own, has a nucleic acid core, a protein coat, and can invade cells and alter cellular function
• heterotrophic, unicellular, animal - like protist

term

• select choice
• select choice
• select choice

Explanation:

1. For "a protein that can cause infection or disease" - This is a prion. Prions are misfolded proteins that can induce other proteins to misfold, leading to diseases like mad cow disease.
2. For "nonliving strand of genetic material that cannot replicate on its own, has a nucleic acid core, a protein coat, and can invade cells and alter cellular function" - This is a virus. Viruses are acellular, have genetic material (DNA or RNA) in a protein coat (capsid), and need a host cell to replicate.
3. For "heterotrophic, unicellular, animal - like protist" - This is a protozoan. Protozoans are single - celled, heterotrophic organisms that share some characteristics with animals, like being able to move and being heterotrophic.

Answer:

1. a protein that can cause infection or disease: Prion
2. nonliving strand of genetic material that cannot replicate on its own, has a nucleic acid core, a protein coat, and can invade cells and alter cellular function: Virus
3. heterotrophic, unicellular, animal - like protist: Protozoan
