Chromosome is to cactus as gene is to needle
Answer:
Attract the female attention
Explanation:
Male sage grouse have feathers to the toes, pointed tail and legs, two inflated air sacs on the neck, brown throat and black belly. In the mating season, many male sage grouse gathers in an open area do courtship display to attract the females.
In their courtship display, they erect their feathers like a peacock do and make blooming sound by inflating their air sac. Females choose that male sage grouse which seems to be more attractive to them and mate with that male sage grouse. Therefore the function of this dance is to attract female attention.
The right answer is the reticular activating system (RAS).
The Reticular Activation System. This is an element of your brain that is useful for capturing your attention and for achieving your goals more easily.
Let's take an example immediately to illustrate what the RAS really means: A loudspeaker announces your name and asks you to pick up your daughter at the reception. And there, your brain, your RAS gets in motion: your attention is at its highest level and you distinctly and clearly distinguish the message and its content addressed to you.
Thus, thanks to the RAS, which starts automatically in your brain, the relevant information is brought to your attention. The RAS plays a role of intermediary, a filter between the conscious part and the unconscious part of your brain. The latter can not store all the information, it is necessary that a relevant sorting is done between them. It's the RAS that does it. It is he who decides what is worthy of attention and what is not. As soon as it judges that information concerns you to the highest degree, he will "wake up" your brain that will absorb it. Thus, as part of our example, the RAS has been instructed to wake up your attention as soon as your name is spoken in the speaker.
Answer:
B) be able to be disproven
Explanation:
Scientific investigations involve the use of scientific methods, which is a principled guideline for scientific observations. One of the steps of the scientific method includes formulating an hypothesis, which is a predictive statement about the possible solution to an observed problem. This hypothesis is FALSIFIABLE i.e it must via experimentation/testing be proven to be false.
This qualifies a happening or phenomena as SCIENTIFIC. It must be able to be repeatedly tested for the purpose of disproven or falsifying the hypothetical claim.
