Answer:
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
3.33 seconds.
<u>Explanation:</u>
We can find the speed of the body using the formula,
Speed = Distance traveled in meters / time taken in seconds
= 450 m / 30 seconds
= 15 m/s
So per second the distance traveled by the body is 15 m.
So time needed to travel 50 m can be found as,
time = distance/speed
= 50 m / 15 m /s
= 3.33 s
Answer:

What is the most easily visible manifestation of the Earth's magnetic field?
A) The Van Allen radiation belts
B) The magnetopause
C) The aurorae
D) There is no easily visible manifestation of the Earth's magnetic field.
For a lunar eclipse (the moon is obscured from view), which phase is necessary?
A) third quarter
B) new moon
C) first quarter
D) full moon
Answer:
The combinations are
1. C ,
2. C ,
Explanation:
The force between two charges q and Q is given by Coulomb's law.
The coulomb force is given by
Where, r be the distance between two charges
According to the question,
r = 15 cm, Q = C, q = C , F = 12 N
Force remains same, distance remains same
so the product of Q and q be same
The product of Q and q is
So other combination of charges are
1. C ,
2. C ,
