3. produces H† ions when added to water:
<em><u>-If no oxygen is present, what process happens during cellular respiration?
</u></em>
If no oxygen is present, cells can only utilize glycolysis to make ATP. Cells without mitochondria can only utilize glycolsis. Glycolysis couples with fermentation to produce ATP. Cellular respiration is the process cells use to make energy. Cells in our body combine glucose and oxygen to make ATP and carbon dioxide. Thus why oxygen is to be present during cellular respiration.
<u><em>-Describe the process of photosynthesis. What are the products and the reactants?
</em></u>
The products is glucose, and the reactants are ATP, NADPH, co2 the of photosynthesis carbon dioxide water. These are the products of photosynthesis glucose and oxygen.
Reactants:
- Carbon dioxide
- Water
- Sunlight
Products:
- Glucose
- Oxygen

Proteins Amino acids Keratin (found in hair and nails), hormones, enzymes, antibodies
Nucleic acids Nucleotides DNA, RNA
Explanation:
Answer: It is a selective and differential medium.
Explanation: Selective medium is used to select the growth of certain bacteria whilst inhibiting the growth of another by preparing a medium with ingredients that will only select a specific growth of intended microbe. When closely related bacteria had been selected, they can further be differentiated by the way they utilize the medium. In this case staphylococcus aureus was first selected using sodium chloride with which only this bacteria can tolerate i.e halophilic (strives in salty environment). It was also further differentiated by its ability to ferment sugars changing the colour of the pH indicator chemical.
