<h2>Answer:</h2>
Option B, the diver will hear the sound first.
<h2>Explanation:</h2>
Sound need a medium to travel from one place to another, the medium where atoms are more closely packed together, the better will be speed of sound. That is why sound won’t travel in a vacuum because there are no particles to bump together to transmit the vibration.
- In air, the particles are generally far from each other so they travel further before they bump into one another.
- In water, the particles are much closer together, and they can quickly transmit vibration energy from one particle to the next. This means that the sound wave travels over four times faster than it would in air.
Answer:
Explanation:
From the given information:
Since the parent are normal; Let assume that their trait is Pp
The affected sister will be recessive in nature, so the trait will be pp
Now, the husband who is the groom will be a carrier with a probability of 2/3 since her sister is affected.
Also, the wife will be carrying a heterozygous trait since she is normal as well.
However, using Hardy-Weinberg assumption:
q = 0.02
Recall that:
Thus, 
2pq = 0.0392
Finally, the required probability that there will be an affected offspring amongst the family is:
Answer:
Magnification power is 600X
Explanation:
15X and 40X indicating that the object is enlarged 15 times and 40 times. Formula is X = lens power X objective lens power.
Extra - Fun fact - The magnifying glass consists of a piece of convex-shaped glass or plastic.
The answer is D. all of the above.
