<span>An example of an epithelial tissue where gases are exchanged is alveolar epithelium, which can be found in the lungs. This tissue is simple epithelial tissue. This is to be expected because the cell layer needs to be thin enough for the gasses like carbon dioxide and oxygen to diffuse or pass through. Stratified epithelial tissue contains several cell layers that would impair the exchange of gasses.</span>
Answer;
an orange that has a prolonged shelf life
Explanation;
-Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism.
-Examples of genetically engineered (transgenic) organisms currently on the market include plants with resistance to some insects, plants that can tolerate herbicides, and crops with modified oil content.
-Genetic engineering works by physically removing a gene from one organism and inserting it into another, giving it the ability to express the trait encoded by that gene. It is like taking a single recipe out of a cookbook and placing it into another cookbook.
