Answer:

Ali hear the sound in 0.046 seconds.

Explanation:

Given:

Distance between Ali and Abdi =  300m

Speed of sound in steel = 6500m/s

To Find :

How much sooner does Ali hear the sound = ?

Solution:

We can find the time in which the sound made by Abdi with a stone on the rail by using the speed formula

We know that

Speed = \frac{Distance}{time}\\

On substituting the given values,

6500 = \frac{300}{time}\\

time = \frac{300}{6500}\\

time = \frac{300}{6500}\\

Time  = 0.046 seconds

Why do sex cells contain only half the number of chromosomes needed for offspring? Explain
Bogdan [553]

Answer:

None, egg cells don't have chromosomes. No, sex cells do have chromosomes. Meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.
