Answer:

There will be three spots that will light up.

Explanation:

There is a research paper published which demonstrated the trisomy of 21 chromosome. They found out that there are total three spots that light up in Trisomy 21 (down's syndrome's fetus). I have attached picture from research paper and provided the reference below.

Reference

(Davies, A. F., Barber, L., Murer-Orlando, M., Bobrow, M., & Adinolfi, M. (1994). FISH detection of trisomy 21 in interphase by the simultaneous use of two differentially labelled cosmid contigs. Journal of medical genetics, 31(9), 679-685)

Kyle is holding a bag of 250 jelly beans. When Mark takes out two jelly beans, Kyle is not able to tell a difference.

Fudgin [204]

Answer:

Sensory adaptation.

Explanation:

Hello.

In this case, after the removal of the two jelly beans, Kyle has now 248 jelly beans which is a slightly neglectable difference, it means that the answer is sensory adaptation since it refers to a decrease in the sensitivity to a stimulus due to the constant exposure to it, which also reduces our awareness when a neglectable change happens.

This is proved since Kyle was constantly holding the bag so a difference of two jelly beans will be almost neglectable making the sensory adaptation the reason behind this.

Regards.

Flagella may best be described as:

vlada-n [284]

Answer:

The correct answer is number one: <em>Filamentous rotating structures that provide motility may be singular, paired or scattered.</em>

Explanation:

Flagella are organelles defined by function rather than structure.

The primary function is that of locomotion but also being sensitive to chemicals and temperatures outside the cell.

Helicobacter pylori is a good example of flagella: It uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium.

Sperm cell is a good example, which uses its flagellum to propel itself through the reproductive tract of females.

I hope it helps!
