If the surface area of a sphere is increased by a factor of 4 what is the change in the length of the radius of the sphere?
The area of a sphere is A=4*3.14 * r^2. Thus the area varies as the square of the radius. If the surface area is increased by a factor of 4, then the radius will have to increase by the square root of 4 which is 2.
If each edge of a cube is increased by 100 percent what is the percent of increase of the surface area of the cube?
1200 percent
What effect does the scale factor have on the area of the enlargement?
The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.
What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
How can you obtain a cell's ratio of surface area to volume?
To obtain the ratio of surface area to volume, divide the surface area by the volume.
What is the area of the body around the belly button is called?
This is called the pyloric region. A sphincter called the pyloric sphincter is found there.
What is pre-pyloric?
The bottom of the stomach is the pyloric area, with the pyloric sphincter separating the stomach from the duodenum (first portion of the small intestine). The top of the stomach is the cardiac area with the cardiac sphincter. The pre-pyloric area is the area just above the phyloric sphincter where they do biopsies to test for an H-Pylori infection. The pyloric area consists of two parts the pyloric canal and the pyloric antrum.
What is the function of the plyoric sphincter valve?
the control of releasing material from the pyloric area of the stomach.
What are the names of the sphincters the stomach?
Sphincters are circumferential muscles that can relax or constrict to regulate the passage of material through a particular area. The stomach is bound by two sphincters in humans: the lower esophageal sphincter that keep stomach acid in the stomach and the pyloric sphincter that regulates the flow of food in the stomach into the duodenum.
What does the pyloric caeca do?
The pyloric caeca are finger-like projections in the intestines of some fish that increase the surface area for nutrient absorption. They also secrete enzymes to aid in digestion.
What happens to surface area of a tire when pressure is increased?
the surface area decreases.
What are sphincters and how are related to the stomach?
Sphincters are circumferential muscles that can relax or constrict to regulate the passage of material through a particular area. The stomach is bound by two sphincters in humans: the lower esophageal sphincter that keep stomach acid in the stomach and the pyloric sphincter that regulates the flow of food in the stomach into the duodenum.
Convolutions of the brain provide increased what?
Convolutions of the brain provide increased surface area for more neurons to be packed in, allowing for greater processing power in a compact space. This increased surface area also enables more connections between neurons, facilitating complex information processing and cognitive functions.
How does the surface area of a mitochondrion or chloroplast affects its energy output?
increased surface area, increases output
How many neurons and intestinal cells each have greatly increased surface area?
Neurons have greatly increased surface area due to their dendrites and axons. Intestinal cells have greatly increased surface area due to microvilli on the surface of the cells that help in absorption of nutrients.
How does increased surface area affect the action of an enzyme?
the greater the surface area the easier it is for them to reach and react with substrates
What is a pyloric ceca?
Pyloric ceca are finger-like projections found in the intestine of some animals, such as fish, amphibians, and insects. They increase the surface area of the intestine for absorption of nutrients and can also play a role in digestion and enzyme secretion.
