In living things, there are 6 common elements that can be found: carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. Among these, the major ones are carbon, hydrogen, oxygen and nitrogen.
The most important of all that characterizes organic matter from the rest, is the presence of carbon. Carbon is a versatile element because it can bond to itself to an unlimited length. Because of this, it makes itself as host to other functionalities like hydroxide, amines and many more. The combination of a length of carbon chains with other of these major elements make up the basic compounds that our body needs. Compounds like carbohydrates, lipids, hormones, proteins and even our DNA and RNA strands are made up of these major elements.
Answer:
It is important for an ecologist to study the habitat, if it is in danger, the food it eats and what eats it.
You need to understand the ideal gas equation to solve this question. Sea level pressure should be around 1 atm. So, the calculation would be:
PV= nRT
n= RT/PV
n= (0.082057 L atm / mol K) (37+273.15)/ 1 atm (5L*20%)
n=<span>25.4499786 moles</span>
