The heart lies in a chest cavity known as the Mediastinum
Answer:
The correct answer is -
1. photosynthesis and cellular respiration
2. glucose and cellular respiration
3. O2
4. C6H12O6
5. CO2
6. H2O
Explanation:
For the survival and growth of a plant, there are several functions and structure are essential but two most important parts are photosynthesis that provides food and glucose for the plant and its nourishment and other is cellular respiration which is required to convert glucose into ATP a form of energy.
In animals, photosynthesis is not possible so they depend on the plants and other sources for glucose and another important process for growth and survival is cellular respiration.
The chemical formula of oxygen, glucose, carbon dioxide, and water is as follow:
3. O2 - oxygen
4. C6H12O6 - glucose
5. CO2 - carbon dioxide
6. H2O - water
<span>If you are asking about gastric acid, its mainly made up of HCl (hydrochloric acid). Intrinsic factors are also produced which are very similar to enzymes. Carbonic acid is produced but also quickly dissociates. -Jo</span>
Algae live in water, and their tails help them swim. Pollen grains have spikes that help them stick to insects such as bees. (hopefully right)
With hosts they can. But not on a place like dry pavement. They like something wet.
