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.

Answer: Metabolic alkalosis
Explanation: Metabolic alkalosis refers to a metabolic condition in which the tissue’s pH is increased above the normal range (7.35–7.45). This occurs as a result of decrease in the concentration of Hydrogen ion, which results to increased bicarbonate in the body system. It can also be caused by direct increase in the bicarbonate concentrations.
Cytoplasm is the thick fluid solution that fills each cell and is enclosed by the cell membrane. It is made up mostly of water, salts, and proteins.
The cells within your own body, and within plants contain cytoplasm. So two real life examples of cytoplasm would be the fluid in your own cells, and the fluid inside the cells of a tree.
