Chemistry for Biologists: Some basic chemistry
Some basic chemistry
Living organisms and chemistry
Biology is about living things - organisms. All living organisms are made of chemicals. To understand biological substances and the changes that take place in living organisms you need a good knowledge of the underlying chemistry. We will build up a picture of the chemicals that make up living organisms by starting small and getting bigger.
The starting point is atoms - the building blocks of all matter. We will then look at how these come together to make elements and compounds.
Time = Distance / speed
Time = 2.5 km / 23 km/h
= 0.1087 hours 1 hour = 60 minutes
= 0.1087 * 60 minutes
= 6.522 minutes.
Answer:
I belive it is the one at the bottom of the table visable in the picture with 27.4 radioactive age
Explanation:
Renewable source means that it can never run out or run out in a long time. In this case the sun is expected to shine for about five billion years because of the high amount of hydrogen that is stored in its core. So the answer should be "The sun is continuously releasing energy". This answer is the best because there are many other renewable resources on earth that can cause pollution.
