What is the primary reason that astronomers put telescopes and other instruments above Earth's atmosphere?

5 0

The main reason as to why those telescopes that are located above the Earth's atmosphere is because the atmosphere absorbs infrared light which comes from the sun and this affects the viewing done by the astronomers. That is why, this is considered as a great disadvantage for those ground-based telescopes. The answer would be the last option.

Answer:

In mitosis, the products are identical to the parent cell, while in meiosis the products are different from the parent cell.

Explanation:

Mitosis replicates DNA at the beginning of the process, so it's always the same, but Meiosis uses a special process called crossing over which causes two chromosomes to swap information, which means that the DNA has changed.

Answer:

Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A

Explanation:

Let the depth of each section is h.

That means the real depth for each section is h.

Apparent depth is liquid A is 7 cm.

Apparent depth in liquid B is 6 cm.

Apparent depth in liquid C is 5 cm.

by the formula of the refractive index

n = real depth / apparent depth

where, n is the refractive index of the liquid.

For liquid A:

$n_{A}=\frac{h}{7}$ .... (1)

For liquid B:

$n_{B}=\frac{h}{6}$ ..... (2)

For liquid C:

$n_{C}=\frac{h}{5}$ ..... (3)

By comparing all the three equations

nc > nB > nA

Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A
