Explanation:
Explanation:
Hydrogen and Oxygen have many properties in common, but they have a lot of differences as well. Both are gases, both are colorless, both are odorless. They both differ from each other in the following regard:
Hydrogen has one unpaired electron whereas oxygen has two unpaired electrons.
Hydrogen can form only one covalent bond whereas oxygen can form two covalent bonds.
The most common isotope in hydrogen has no neutron in its nucleus whereas there are 8 neutrons in most common isotope of oxygen.
Atomic mass of oxygen is far greater than that of hydrogen. Hydrogen has an atomic mass of 1.00794u where as oxygen has an atomic mass of 15.999u
Answer:
<em>They deliver oxygen to the blood.</em>
Explanation:
The main function of the respiratory system is to provide oxygen to the body and to remove carbon dioxide from the body. Oxygen is transported to all ports of the body via blood vessels from the lungs. The alveolar sacs, present in the lungs, allow oxygen to be transported to the blood and carbon dioxide to be taken up.
The organs of the respiratory system include nose, pharynx, epiglottis, larynx, trachea, Bronchi, Bronchioles, alveolar sacs of the lungs.
Photosynthesis is an important process in plants in which they produce glucose which serves them as food. This process occurs in the green leaves of the plants, thanks to the green pigment chlorophyll in the organelles known as chloroplasts.
If the question is what will happen to the plant, it will no longer have green leaves, and the rate of photosynthesis will be significantly decreased, but not stopped because there will probably be other pigments (non-green) able to <span>absorb sunlight.
</span> If the question is what will happen to <span>chloroplast if it is taken out of the cell and illuminated, i</span>ts pigment chlorophyll will absorb red and blue light,and reflects green light.
