Answer:
C. 50%
Explanation:
Baldness is sex-linked, so we need to use the X and Y chromosome notation. Let's represent baldness with B, and no baldness as b.
Man: XB Y
Woman: XB Xb
(Remember, she's a carrier: so she has one B allele, but not both, otherwise she would express the trait.)
What's next - Punnett square, our old buddy:
XB Y
XB XB XB XB Y
Xb XB Xb Xb Y
So out of that square, they've got two males. That's our denominator. And it wants to know how many male progeny will be bald: that's only one, the one with XB Y. He will express the B allele because the Y's kinda just like a placeholder. So the probability is <u>50%.</u>
The observation of classmates dropping the magnet in science class lecture can be hypothesised in the following manner:
What happens to the magnet after getting dropped? (3 questions)
1. Does dropping the magnet on the floor reduces its magnetic strength?
2. If the magnet breaks into two parts after getting dropped, are the two parts still attracting each other?
3. Does dropping a magnet flip its magnetic poles?
Why are they dropping (2 questions):
1. The magnetic pull of Earth is greater than the frictional force due to fingers on the magnet. This causes the magnets to slip through the fingers and fall on the ground because of magnetic pull.
2. Hands tend to sweat when gripping a magnet. The sweat reduces the grip and the magnet falls.
