Answer:
A
Explanation:
Selective breeding takes a person and so does cloning
Nitrogen and oxygen make up about 99%of the atmosphere. I'm not sure if it will help! But thats all I know.
Answer:
1. B
2. C
(check with your teacher to make sure and explain it to you)
Answer : cathode, protocathode
During an electrochemical reaction, electrons move through the external wire toward the cathode and positive ions in the salt bridge move toward the protocathode.
She should investigate how temperature affects the rate of oxygen production.
<h3>Photosynthesis</h3>
During photosynthesis, green plants make use of inorganic products in the form of water and carbon dioxide to synthesize carbohydrates. The reaction only happens in the presence of solar radiation and oxygen is evolved as a by-product.
The process involves a series of chemical reactions. However, the summary of the whole reactions is represented by the following equation:
carbon dioxide + water ----> glucose + oxygen
Thus, if Emily is to find out how temperature affects photosynthesis. She will need to use a plant as a case study. One factor that can easily be used to measure the rate of photosynthesis is oxygen production by plants.
In other words, Emily will have to set up an experiment where a plant species will be subjected to the same environmental conditions, except temperature. Then, a suitable method will be used to measure the amount of oxygen produced. Any difference in the volume of oxygen produced can then be attributed to the effects of temperature.
