Hypothesis: If Plant Food X is used on a tomato plant, then production rate will increase.
experiment: Gather 2 tomato plants of the same height and age. Make two groups, a control group (a tomato plant without use of fertilizer) and an experimental group (a tomato plant with using Plant Food X).
For one week, give each plant the same amount of water, humidity, sunlight, and air temperature. after a week measure the height and number of tomatoes produced. gather the info in a table and compare to hypothesis after one week.
<span>D.Oxygen will diffuse from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell). This is because cells respire constantly, as this process uses up oxygen cells will contain less oxygen than its surroundings. Oxygen moves by the process of diffusion, in diffusion a molecule will always move from a higher concentration to a lower concentration.</span>
answer: D. Graph D I took the quiz
The correct answer is option B
Carbon dioxide is present in the environment along with the other gases and still it is considered as a pollutant when its concentration in the atmosphere increases than the normal concentrations.
The normal concentration of the carbon dioxide is maintained by the help of plants that use carbon dioxide for the process of photosynthesis.
The increased amount of carbon dioxide in the atmosphere is caused due to the human activity.
Industrial release, pollution from automobiles are some of the sources of carbon dioxide emission.
