Answer:
I want to say the answer is Form a hypothesis
I say this because a hypothesis is one of the first things you do when conducting an experiment and when forming a hypothesis you use the format "if...then....because". You are giving a possible answer to your question before you actually perform the experiment. I hope this helped.
Explanation:
Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies
.
Sampling - Done by counting the animals in a small area and then estimating how many are in the larger area. You go out and take samples from different places so you can take the average. In most cases, it is not possible to count every member of a population so an estimate is made.
Mark and recapture - Another estimating method is a technique called "mark and recapture." This technique gets its name because some animals are first captured, marked, and released into the environment. Then another group of animals is captured. The number of marked animals in this second group indicates the population size.
Indirect observation - The members of a population may be small or hard to find. It may be easier to observe their tracks or other signs rather than the organisms themselves.
Direct observation - The most obvious way to determine the size of a population is to count, one by one.
Answer:
Second!
Explanation:
speed and velocity are both measured using the same units.The S.I unit of distance and displacement is the meter. The S.I unit of time is the second. The S.I unit of speed and velocity is the ratio of two-the meter per second!

<span>This would be a positive reinforcer. These are things like rewards and bonuses that will cause the subject to want to continue the rewarded behavior. The reinforcer does not need to be financial or even tangible. Positive comments and approval can be reinforcers that strengthen associated behaviors.</span>
