During elongation, a cell can increase its volume by approximately 10 to 20 times due to the uptake of water. This process involves the vacuole expanding as it accumulates water, leading to turgor pressure that drives cell elongation. The exact increase can vary depending on the cell type and environmental conditions.
What else can I help you with?
What happens to the intrapulmonary pressure when intrapulmonary volume increases?
When intrapulmonary volume increases, the intrapulmonary pressure decreases. This creates a pressure gradient that allows air to flow from higher pressure outside the lungs to the lower pressure inside the lungs during inspiration.
As a cells volume increase is what happens to the proportional amount of surface area?
As a cell's volume increases, its surface area also increases, but at a slower rate. This is because surface area scales with the square of the diameter, while volume scales with the cube. Consequently, larger cells have a lower surface area-to-volume ratio, which can limit the efficiency of nutrient uptake and waste removal. This relationship is a key factor in cellular size constraints and the necessity for cell division in larger organisms.
What happens to volume as temperature changes?
if volume of a gas increases temperature also increases
According to Charles law when the temperature of a gas increases in flexible container its?
When the temperature of a gas increases in a flexible container, its volume also increases proportionally. This is because the kinetic energy of the gas particles increases with temperature, leading to more collisions with the container walls and hence an increase in volume.
What happens to the volume of the thoracic cavity during the respiratory cycle?
During inspiration, the volume of the thoracic cavity increases as the diaphragm contracts and the rib cage expands. This allows air to be drawn into the lungs. During expiration, the volume of the thoracic cavity decreases as the diaphragm relaxes and the rib cage recoils, causing air to be expelled from the lungs.
Is as cell surface area increases cell volume increases faster true?
Yes, as cell surface area increases, the cell volume increases at a faster rate. This is because the surface area to volume ratio decreases as the cell grows larger, which can affect the efficiency of nutrient uptake and waste removal within the cell.
What happened to tidal volume during hyperventilation?
Tidal volume increases.
Which metal increases in volume during solidification?
Gallium
What happens to volume during phase changes?
Volume increases with increase in temperature, and decreases with decrease in temperature.
What is the rationale for reducing dietary salt for patients with high blood pressure?
Salt which is taken in by the body into the blood, causes the water in the body to follow salt into the blood vessels. This increased uptake of water into the circulatory system increases the volume of blood in the blood vessels. This increased volume increases blood pressure.
What happens to lung volume during inspiration?
During inspiration, lung volume increases as the diaphragm and external intercostal muscles contract, causing the chest cavity to expand. This expansion creates a pressure gradient that allows air to flow into the lungs, filling them with oxygen.
What happens to the intrapulmonary pressure when intrapulmonary volume increases?
When intrapulmonary volume increases, the intrapulmonary pressure decreases. This creates a pressure gradient that allows air to flow from higher pressure outside the lungs to the lower pressure inside the lungs during inspiration.
When does the lung relax?
The lung doesn't relax, it is controlled by the diaphragm When it relaxes the volume of the lungs decrease during expiration When it contracts the volume of the lungs increases during inhilation
When does your blood volume increase during pregnancy?
Blood volume increases during pregnancy starting around the 8th week and continues to rise until around the 32nd week.
As a cell increases in size the a. metabolic rate increases. b. surface area to volume ratio increases. c. volume increases and the surface area increases. d. surface area increases and the volume d?
As a cell increases in size the volume increases much faster than the surface area. The possible answer is C.
When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
How do you calculate elongation and area reduction?
Intial volume = final volume from this approach if you know any one of them % reduction in area or % elangation. you can calculate other
