Which circumstances could be sources of error within the experiment? check all that apply
not fully submerging the object when doing the fluid displacement procedure
water that is left behind in the collection container when it is transferred for measurement
water that soaks into the materials of the balls, affecting the mass in repeated trials
the time of day when the measurements are recorded
water in the bucket, approximated to the closest 10 ml due to surface tension at the top of the bucket
the air pressure in the room and its affect on the scales that measure the mass of each object

A, B, C, E

Explanation:

A. not fully submerging the object when doing the fluid displacement procedure.

B. water that is left behind in the collection container when it is transferred for measurement.

C. water that soaks into the materials of the balls, affecting the mass in repeated trials.

E. water in the bucket, approximated to the closest 10 mL due to surface tension at the top of the bucket.

1: the largest region of the brain is the:

  cerebrum

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis
