The nitrogen fixation is the process of conversion of nitrogen gas into a usable form.
Answer: Option 3
<u>Explanation:
</u>
The nitrogen fixation is the process where the nitrogen gas present in air gets trapped and converted into ammonia or other nitrogenous compounds. This is the first step of nitrogen cycle.
The atmospheric nitrogen will get absorb in soil and gets converted to either ammonia which acts as nutrition for plants or other nitrogen related compounds which acts as fertilizers.
So, the nitrogen which get converted to usable stable form of nitrogen compounds can be used by plants, microorganisms and other organisms in the ecosystem.
I think the answer is c. the more characteristics they have in common. Sorry if wrong.
The answer is C (They are inversely proportional). I have had this question before and C is the correct answer.
Answer:
a structural variation in which different atoms of the same element have different numbers of neutrons
Explanation:
An isotope is an atom of an element having the same number of protons but different number of neutrons. Different isotopes are used for different purposes. Example: some are used in medicines , food irradiation, etc.
Carbon has three isotopes C 12, C 13, C 14. All three of them have 6 protons but have different numbers of neutrons.
C 12 is a common element and is abundant in nature
C 13 is less abundant than C 12
C 14 is used for dating fossils . It is radioactive
Answer:
atoms and molecules
Explanation:
as opposed to being continuous or just including particles). On the following page, the idea is stated as one of four concepts in Dalton's theory: “All matter is composed of tiny, indivisible particles called atoms”
