Answer:
The correct answer is C. <em>"Cartilage, smooth muscle layers, mucosa, circular muscle". </em>
Explanation:
The intestine wall is conformed of 4 layers: mucosa, submucosa, muscular and serous.
- The mucosa layer is composed of cylindrical simple epithelium that shapes tubular glands named Lieberkühn crypts and villus, these las one in charge of absorption. The crypts are invaginations of the epithelial surface and they have the stem cells. The epithelial cells renew constantly, so cells divide in the base of the crypts and then they move to the superior portion of the digestive tube, where they die. This layer also has a basal sheet and a thin muscular sheet.
- The submucosa layer is composed of dense connective tissue, with adipose tissue located in some specific areas and large-caliber blood vessels.
- The muscular layer is composed of two bands disposed perpendicularly between them, the <u>internal thick circular muscle</u> and the <u>external thin longitudinal muscle layer</u>.
- The serouse layer is composed of a very thin connective tissue that in some points continues with the peritoneum.
Answer:
The geologic time scale is the calendar for events in Earth history. It subdivides all time into named units of abstract time called escending order of duration eons, eras, periods, epochs, and ages.
The substances water, oxygen, and adenosine triphosphate (ATP) are produced by cellular respiration.

Plants and animals live in interacting, interwined communities. There is a characteristic set of species in different environments. For example, certain species of trees, shrubs, ground cover, arthropods, reptiles, mammals, birds etc. live in a temperate forest environment. A completely different set of creatures live in a marsh, or a grassland or an agroecosystem. However, the relationships between these groups can be defined by the ecological role they play, the flow of energy between them and the cycling of nutrients between them. This is a fancy way of saying "everything is connected"! And if you change one part of the system, something else changes. In an ecosystem management decision, you hope you know what those consequences of your actions are!) This is important in managing agroecosystems as well.
Answer:
Through negative feedback, insulin produced by the pancreas causes a decrease in the amount of glucose in the blood.
Explanation:
The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.
