The outer planets are mostly formed of lighter elements because these three condense are a<u> lower temperature</u>.
<u>Explanation:</u>
The planets based on the location of the sun is divided into two, that is outer planets and inner planets.
The Outer planet which is far from the sun consists of larger quantity of lighter substances such helium, hydrogen, methane which would condense at the lower temperature. And remains gaseous inside the frost line that would exit far away for the sun so the temperature is low and the lighter materials are easier to condense in lower temperature to form terrestrial rocks.
In the world's oceans 90% of the biomass is microbial with viruses turning over 20% of that daily. without the turnover of biomass driven by viruses many sources of food would not be present for other organisms
Answer:
16) 6 electrons
17) 6 protons
18) 6 neutrons
19) 4 electrons
20) 6
Explanation:
There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.
Answer: B: the variety of living things on Earth.
(Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.)
Chemically speaking, enzymes are composed of chains of amino acids, and they are considered to be a type of protein.
