Planets are formed of rock, dust and gasses. A planet has different layers. Terrestrial planets are made of rocks and dust and gases form its atmosphere. Jovian planets are composed of gases which may or may not have solid core.

In solar system,  the first four planets are terrestrial and next four are Jovian.

Mercury has no atmosphere.

Venus has a very thick atmosphere composed of carbon-dioxide.

Earth's atmosphere is made up of Nitrogen and oxygen.

Mars has a very thin atmosphere composed of Carbon-dioxide.

The Jovian planets: Jupiter, Saturn, Uranus and Neptune are composed of Hydrogen. Neptune and Uranus are blue in color due to presence of Methane in their atmosphere.

Why is the ability of the cell membrane to be "picky" important?
Yuliya22 [10]

Answer:

Hi there!

Your answer is:

It is very important for the cell membrane to be <em>semi-permeable</em> because the ability to pick and choose what comes in and out of the cell keeps the cell safe! The membrane can choose to block out nasty germs and can also choose to get rid of internal waste.

An example of when this is important is in this scenario:

Let's say the cells are in a really salty solution. Naturally, salt will want to pull the water out of the cell. If the membrane <u>wasn't</u><u> </u> semi permeable, the water would listen to the salt and leave the cell. This would cause cell death. <u>BECAU</u><u>SE</u> the membrane is semi permeable, they can choose <em>not</em> to give the salt any water, keeping them alive

Hope this helps
