Some people believe that applying lavender oil will make you less stressed by causing the brain to release serotonin. To test this, scientists set up an experiment with three groups. The first
reported their stress levels on a scale of 1-10 at the beginning and ending of a two hour period.
At the beginning of the two hour period, they applied simple water droplets to themselves. The
second and third groups reported their stress levels at the beginning and ending of the same
two hour period, but applied two different amounts of lavender oil to themselves at the
beginning of the two hours.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

the answer is a) cell division.

hope this !
