That is TRUE, which makes updating maps extremely easy and convenient, not to mention it's the key element in GPS systems.
Answer:
The answer is c.
Explanation:
Age structure data can include all of these aspects except for c I believe.
Answer:
plicae circulares and intestinal villi
Explanation:
The inner wall of the intestine is full of wrinkles, called villi. An enlargement of them under the microscope reveals that they are formed by cells whose surface has innumerable small "wrinkled" structures. The small intestine is the largest viscera of the body (about six meters). Intestinal villi and microvilli increase the area of contact with the intestine as well as the speed of absorption of food. Blood capillaries and lymph are in these villi to absorb nutrients.
The intestinal villi, have the function of increasing the absorption of nutrients after digestion. They are the folds of the intestines. The surface of the villi has an area of 12 cm² and the microvilli 240 cm².
Villi and microvilli increase the area of intestinal absorption by approximately 30 times and 600 times, respectively, providing exceptionally efficient absorption of nutrients in the lumen.
The entire small intestine has circular folds of mucosa, also called Kerckring valves and circular plicae. Most extend transversely around the small intestine cylinder for about half or two-thirds of its circumference, but some form complete circles, and some have a spiraling direction; The latter usually extend a little more than once around the bowel, but occasionally two or three times. Circular folds slow the passage of partially digested food along the intestines and provide an increased surface for absorption.
According to the research, decomposers are organisms responsible for returning nutrients back to the soil.
<h3>What are decomposers?</h3>
They are different organisms such as bacteria and fungi whose main function is to break down the waste of plants and animals.
With the decomposition process where organic matter is processed into inorganic, simple elements (nutrients) reappear in the soil that are used as food by plants.
Therefore, we can conclude that according to the research, decomposers are organisms responsible for returning nutrients back to the soil.
