The answer is the first three statements:

  1. Viruses are acellular.

    • This statement is true. Viruses are not made up of cells; they are acellular. They consist of genetic material (either DNA or RNA) surrounded by a protein coat and, in some cases, a lipid envelope.

  2. Viruses are nonliving.

    • This statement is true. Viruses are considered nonliving because they cannot carry out metabolic processes on their own and require a host cell to replicate.

  3. Viruses consist of nucleic acid and protein.

    • This statement is true. Viruses are composed of nucleic acid (either DNA or RNA) and a protein coat called a capsid. Some viruses also have an outer lipid envelope.

  4. Viruses include viroids.

    • This statement is false. Viroids are not viruses; they are smaller infectious agents that consist solely of a short strand of circular RNA and do not have a protein coat. They primarily infect plants.

  5. Viruses are prokaryotic.

    • This statement is false. Viruses are not classified as prokaryotic or eukaryotic because they are not cells. Prokaryotes are unicellular organisms without a nucleus, such as bacteria, whereas viruses are acellular.

In summary, the true statements regarding viruses are that they are acellular, nonliving, and consist of nucleic acid and protein.

Match the developmentalist with the contribution they made to the theory of attachment. Attachment is made between infant and the person who feeds them (oral stimulation). [Choose] Attachment is NOT based on oral stimulation. Using monkeys, this person showed that attachment is related to the comfort infants receive. [Choose] A sense of physical comfort and sensitive care establish attachment and set the stage for healthy attachment for the rest of a person's life. [Choose] Both infant and parent are biologically predisposed to form attachments. [Choose] Used the "strange situation" experiment to formulate attachment styles secure, avoidant, resistant, and disorganized. [Choose]
