It is relative dating because no scientist can tell the actually time that the layers of rocks where formed or when the fossil began to degrade
Answer:
True
Explanation:
In phase-contrast objective and a phase contrast optical systems is equipped with Light microscope .
Phase contrast microscope is used to differentiate unstained structures in a cell that differ in refractive indices and thickness. Thus it is usefull for examining living unstained organisms.
Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.
Hoping this might help!!!
Number 1 is true the second one is true the third is true number 4 is true and lastly number 5 is false I hope this helps you but I’m very confident!
Hi i might be late but it’s B i hope i helped!
Answer:
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.
