Billions of years ago, a meteor the size of Mars collided with the Earth, causing the Earth's outer layer to be vaporized. The debris from this vaporization then reformed as the moon. What would have happened if the building blocks of life existed during this collision? They would've been wiped out instantly.
Accordingly, could life have survived near the ocean floor in ancient Earth?
Could life have survived near the ocean floor in ancient Earth? Survivors could survive off the abundant water and nutrients and heat in the form of chemical energy. It has been found that organisms today are genetically kinned to the earliest organisms we believed existed on the Earth Photosynthesis 25.
One may also ask, what are the building blocks of carbohydrates?
Monosaccharides. They are the building blocks of all other carbohydrate molecules. They are monomers: smaller molecules that bond together to form long chains called polymers.
How did oxygen form on Earth?
The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. "What it looks like is that oxygen was first produced somewhere around 2.7 billion to 2.8 billon years ago.
What are the building blocks and functions of carbohydrates?
Types of biological macromolecules
|Biological macromolecule||Building blocks|
