Which statement is true?
Phantasy [73]

Answer:

Viruses are acellular.

Explanation:

Viruses do not have cells, so we can say that viruses are acellular organisms, the structural and functional unit of living things. This feature contradicts the Cell Theory, which says that all living things are formed by cells. Therefore, because they do not have cells, many claim that viruses are not living things.  Viruses are only able to reproduce within a host cell. For this reason we say that they are obligate intracellular parasites.

Answer: The drive theory of motivation.

Explanation:

The drive threory of motivation is based on the principle that organisms have certain psycological or physiological needs (in this case, hunger). When those needs are not satisfied, a tension in the organism is produced, and with it a drive to seek the satisfaction of that need.

Because the substance the rat recieves is nonnutritive (it doesn't reduce the rat's hunger), we can clearly see that the rat isn't performing the response because of this drive, seeking for the satisfaction of its hunger, but is motivated by another feeling. Therefore, this observation is problematic for the drive theory of motivation.
