Answer:
People with Rh- blood can give blood to both Rh- and Rh+ recipients. However, those with Rh+ blood cannot give to Rh- recipients. If a person receives blood from someone with an incompatible blood type, it can cause a life threatening immune system reaction.
The water cycle, is the answer.
Photosynthesis is measured by the amount of oxygen produced. Counting pondweed bubbles or using the Audus apparatus to determine the amount of gas evolved over time can both be used to quantify oxygen.
<h3>
What is photosynthesis?</h3>
Photosynthesis is the conversion of light energy into chemical energy by green plants and other organisms. Light energy is collected and utilised by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
The forming bubbles are either counted or recorded using light barriers, which is difficult due to their small size and frequently changing ascent velocity. When gas bubbles produced during photosynthesis by aquatic plants leave the plants, they produce different sound pulses.
B. Because the gas collected contains water vapor in addition to oxygen, it is not pure oxygen.
