Researchers can be bias in their studies as they seek to establish and fine tune results in the way the best favors them. A double-blind study helps to bridge this gap to prevent bias that might be introduced into an experimental set up or while interpreting results.
Heat can be transferred from one place to another by three methods: conduction in solids, convctn in fluids, and radiation through anything that will allow radiation to pass. The method is used to transfer the heat is usually the one that is the most efficient

Answer:
artificial selection/selective breeding
Explanation:
The illustration is an example of <u>artificial selection.</u>
<em>By definition, </em><em>artificial selection</em><em> is the deliberate perpetuation of some traits in living organisms simply because the traits are desirable. The organisms are selected because of the traits and allowed to breed either naturally or otherwise in order to ensure that these traits appear or are even consolidated in the offspring of the breeding. </em>
The offspring from selective breeding are expected to combine the desirable traits of the two parents and thus, appear better than each of the parents.
Curare will bind to the receptor but it doesn't cause the ion to flow inside. This will prevent the person from sent signal to the muscle. When the person trying to move the muscle, curare will also prevent acetylcholine to bind so there will be no muscle contractions. The symptoms would be paralyzed of muscle that uses ach receptor.
