Answer: The question is not complete as options are not complete , the remain part are;
A. 3.7 years, photosynthetic bacteria.
B. 3.7 years cyanobacteria.
The correct option is
3.7 billion years old, cyanobacteria and stromatolite.
Explanation:
This is because cyanobacteria is the oldest fossil to exist and they have been in existence for about 3. 7 billion years. These cyanobacteria photosynthesized because they have thread like chlorophyll filament, they produce food through the process of photosynthesis which is needed for their survival and they release oxygen as bye product.
The cell theory consists of:
1. all living organisms are made up of cells
2. cells are the basic structural/organizational unit of all organisms
3. all cells come from pre-existing cells
Explanation:
Iodophor -
Iodophor is a complex of iodine , with solubilizing agents , such as the povidone , surfactant .
And forms a water - soluble material which can release free iodine in the solution phase .
Dilute form of iodophor is used by winemakers and brewers to sanitize their equipment and bottles .
The major advantage of iodophor over other is that , it increases the stability of iodine .
This is called a behavioral pattern. This is something deer have learned over time that gives them an advantage in the wild.
