Answer:
Newly exposed or newly formed rock is colonized by living things for the first time.
Explanation:
In other world rock is being inhabited. A community is beginning to form.
Answer:
- Transpiration is loss of water vapor from leaves.
- Guard cells regulate whether stomata are open or closed based on availability of water in the plant.
- When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphere
Explanation:
The gas exchange of plants is part of the cellular respiration process, where the plants both remove and release gases into the atmosphere. This exchange happens through structures present in the leaves of plants, which are called stomata. Stomata function as doors, if they are closed it is impossible for the plant to promote gas exchange, but if they are open. Transpiration occurs with the release of water vapor through open stomata. It is in this water vapor that the plant releases oxygen into the atmosphere.
The opening and closing of the stoma is a highly regulated process, because opening the stoma makes the plant lose water. In this case, the guard cells are responsible for opening and closing the stoma whenever necessary and the plant has good water levels.
This might be considered invalid because the slug was not monitored on which piece of lettuce it went to first. Also, the experiment was only done one time. An experiment should be done multiple times to make sure there is as little human error as possible.
