Austin and Marissa should observe the number of open stomata on one leaf, mist the leaf with water, wait one hour, and count the number of open stomata again.
In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
Stomata, the tiny pores on the outside of leaves and stalks, control how gases enter and exit leaves and therefore, how plants as a whole function. On all periods, ranging from minutes to millennia, they adjust to regional and global changes.
Guard cells are a pair of specialized epidermal cells that make up stomata. By adjusting the size of the stomatal pore, stomata govern water loss and the exchange of gases between the plant and its surroundings.

Answer:
Hypothesis: If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue.
Explanation:
In a scientific research the hypothesis is an assumption, a possibility that will justify the purpose of the scientific research and will help in the establishment of all the steps of this research, so that it is possible to determine if the hypothesis is true or false. In other words, we can say that the hypothesis must be formulated as an assumption, before the research that will prove it or not.
An example of a hypothesis about research on the longevity of cells that line the esophagus is: "If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue."
