Benny is observing different species of animals and their behaviors. His hypothesis is that smaller creatures, like mice and rabbits
will be more active than larger creatures, like dogs and cats. He observes several small and large animals. What should Benny do
with his observations?
A.
forget about the observations
B. take notes on the observations
C. remember the observations in his head
D.
draw a conclusion immediately after observations

Option D. draw a conclusion immediately after observations.

Explanation:

In this experiment, hypothesis is made after observing the species of small and large animals. Hypothesis is a statement that may be true or false. After observing a large number of small and big animals, so he make a conclusion about what he observed in the experiment. This conclusion will help him in further studies and experiments.

Benny should take notes on the observations.

Explanation:

His hypothesis, that smaller creatures, like mice and rabbits  will be more active than larger creatures, like dogs and cats can be proven if he takes notes when do animals eat, how many times and when do they sleep.

He'll eventually prove his hypothesis because smaller animals tend to have faster metabolic rates than the larger ones. Hence, smaller animals will be more active in their daily activities.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
