A student in a histology class was asked to describe the structure of a stratified squamous epithelium. Which of the following s
hould he use? Group of answer choices a. tissue composed of contracting protein fibers enclosed by plasma membranes
b. tissue composed of one layer of flat cells located on a basement membrane
c. tissue composed of protein fibers in a ground substance and a few cells
d. tissue composed of several layers of tall cells resting on a basement membrane
e. tissue composed of several layers of flat cells resting on a basement membrane
The correct option is e. tissue composed of several layers of flat cells resting on a basement membrane
Explanation:
When you look in the miscorscope the structure of a stratified squamous epitellium, you can see several layers of flat cells resting on a basement membrane. In this kind of epitellium not all cells are flat, some have a different shape. As you can imagine, only one of the layers are in touch with the basement membrane.
Another feature of the stratified squamous epitellium is that it can have keratin or not. Examples of this epitellium are found in skin or esophagus.
I can’t see your answer choices, but igneous rocks are made from cooled lava or magma. This is why these rocks are so brittle and grainy. I’ve attached a helpful image to better explain! Good luck!!!
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules.
Explanation:
After the energy is transferred, the energy carrier molecules return to the light-dependent reactions to obtain more energized electrons.
The answer is letter C. The distribution of oak trees in an
area.
Population Ecologist would often measure the number
distribution and density of the area. Trees are often measured by plots or by
hectares. This is to know how many trees are situated in that
area.
