Where does the oxygen that we breathe come from? (Multiple Choice)

Biology

satela [25.4K]3 years ago
6 0

Answer:

Water

Explanation:

Scientists agree that there's oxygen from ocean plants in every breath we take. Most of this oxygen comes from tiny ocean plants – called phytoplankton – that live near the water's surface and drift with the currents. Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food.

Hope this helped, Have a Wonderful Day!!

Stells [14]

Answer

Use Mitosis to divide and create daughter cells.

Explanations  

Single-celled organisms use mitosis to reproduce. Both growth and reproduction in unicellular organisms are mutually inclusive. When the cell’s volume grows, the ratio of surface area to volume decreases creating challenges in acquisition of nutrients because there will be too much cytoplasm for a given amount of nuclear material , thus the cell divides by mitosis to reproduce daughter cells and the process begins again.
