In testing a hypothesis thatʺterritorial defense in European robins is a fixed action pattern that isreleased by the sight of o

range feathers,ʺresearchers found that robins defended their territory byattacking anything that was of similar size and had an orange patch. What experiment would youperform next to determine that the color initiated the defense response?A) Repeat the experiment by removing the patch completely.B) Repeat the experiment using a blue patch instead of an orange patch.C) Repeat the experiment by using a model of a robin that was twice the size of a normal robinbut with a small orange patch.D) Repeat the experiment by using a model of a robin that had an orange patch that was twicethe size of a normal patch.

Answer:

The correct answer is option A) "Repeat the experiment by removing the patch completely".

Explanation:

In this example, researchers believe that European robins have a territorial defense pattern where they attack anything similar to orange feathers, including an orange patch. In order to establish if the color initiated defense response is real it is necessary to repeat the experiment by removing the patch completely. If the European robins do not longer attack, then the researchers can conclude that the color initiated defense response is real.

Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to he
Dahasolnce [82]

Answer:

D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Explanation:

According to this question, some types of syrup contains an entirety of glucose molecules. Hence, eating a syrup like this will have no effect on the person's ability to exercise, however, since glucose is the simplest unit of carbohydrate food sources, it gets digested easily.

Originally, glucose molecules, which are products of digestion, enter into our cells to be used to synthesize energy. However, for a syrup already made up of glucose molecules, the digestive system would not work as hard, since glucose is already small enough to get to her cells.

Explain the statement “Scientific knowledge is the result of debate and conformation within the scientific community.”
spayn [35]

Answer:

What this statement means is that experimentation is not enough, but that true knowledge comes from the analysis of results in a critical and meticulous way

Explanation:

Scientific knowledge is based on the scientific method and the results of the research, however that information is useless if it is not interpreted.

When the results are analyzed by scientists who support the same theories and have the same opinions, the results are not enriched as much as when exposed to different points of view. The debate tests the hypothesis giving rise to more complete answers.
