Overlearning"" in habituation (or below-zero habituation) can occur if . A. several different stimuli are used B. an intense stimulus is used C. habituation trials continue after the response has disappeared D. habituation trials are widely spaced over time

C. habituation trials continue after the response has disappeared.

Explanation:

habituation involves the complete elimination of a particular response (i.e, zero frequency of occurrence). If the stimulus cintinues to be presented for an additional number of trials, then, although no further changes occur, the response will exhibit lower levels of recovery (e.g, spontaneous recovery is reduced) as if the response would have fallen below a zero frequency.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
