Answer:
Gas.
Explanation:
Gas which is present makes the three bottles different from one another. There are three factors which is used for testing of cellular respiration such as amount of oxygen consumed during this process, amount of glucose used and amount of carbondioxide produced during cellular respiration. During cellular respiration, oxygen used in order to break down glucose and releases high amount of energy with the waste materials such as carbondioxide gas.
Oxygen was initially created in Earth's atmosphere by algaes. It is estimated that marine plants produce between 70 and 80 percent of the oxygen in the atmosphere. Nearly all marine plants are single celled, photosynthetic algae. Hope this answers the question.
The doctor is responsible for all of the above.
Answer:
a) Humans depend upon other organisms for food and oxygen
Explanation:
Biodiversity refers to the richness in the species of organisms on Earth i.e the variety of biological organisms on the Earth. The importance of biodiversity cannot be overemphasized because of our dependence on the sustainability of biodiversity in our ecosystems.
The loss of biodiversity, which is becoming rampant by the day, is a major concern to us because we humans depend upon other organisms for food and oxygen. Humans are strictly heterotrophic and hence are reliant on variety of organisms for food. Plants also release oxygen gas via their photosynthetic process, which is key to our survival as a population.
