List and explain major sources of error in the investigation of a Yeast Respiration lab.?
oxgen conc will decrease and ethanol will eventually be produced . if temperature is increased more yeast may divide and hence respiration of yeast will increase but in this case not due to temp.
When heat is added to a situation what 3 things happen?
- the volume increase- the density decrease- a chemical reaction may occur- a change of phase is possible
What chemical process may be described as the opposite of respiration?
Photosynthesis is considered as the opposite of respiration.
Cellular respiration is called an aerobic process because?
Some forms of cellular respiration may be referred to as aerobic respiration because OXYGEN is used in the process. Those forms wherein oxygen is NOT used are referred to anaerobic respiration.
What does the land elevation do moving inland?
It may increase or decrease.
When you decrease volume what are you observing?
If you are talking about a gas, you may be observing a decrease in pressure or temperature or both.
Does water keep its volume?
In general, yes, but lots of things may cause its volume to change. The volume will change if temperature or pressure change, or if something dissolves in the water. Volume may also decrease by evaporation.
Does the mitral valve prolapse increase decrease the stroke volume?
Mitral valve prolapse may decrease the stroke volume, if it is associated with significant backflow. It decreases the effeciency of the left ventricular contraction.
Why volume of toluene decrease after extraction?
It may trapped in your sample, if it's a polymer for example. Or it may reacted with a substance in the solution.
How does cell growth affect the cell's surface-to volume ratio?
The rate at which the cell increases in size depends on the DNA. The ratio of the surface area (calculated: length x width x # of sides) is divided by the cell volume (calculated: length x width x height). THE VOLUME OF THE CELL INCREASES MORE RAPIDLY THAN THE SURFACE AREA, CAUSING THE RATIO OF SURFACE AREA OVER VOLUME TO DECREASE. This decrease causes cell malfunction. If the cell volume increases too much, then the ratio will decrease causing problems for the cell's regular functions.
What is a gradual increase in volume?
The mass and density are increasing more rapidly than the volume is increasing as it is ten dimensions rather than two or three but may be at least five dimensions. Volume may not stay the same volume at all the masses but has to change with the decrease or the increase but it may decrease when mass increases when we are trying to put the molecules too close to increase the density of the universes
Why is pulmonary edema treated with phlebotomy?
Patients with pulmonary edema may undergo phlebotomy procedures to decrease their total blood volume.
List and explain major sources of error in the investigation of a Yeast Respiration lab.?
oxgen conc will decrease and ethanol will eventually be produced . if temperature is increased more yeast may divide and hence respiration of yeast will increase but in this case not due to temp.
What will a decrease in the price of a particular product result in?
A decrease in the price of a particular product will result in higher demand. It may also result in shortages if the product cannot be produced fast enough for consumers.
What affects someones respiration rate?
In physiological conditions, the respiration rate grows with the need of oxygen and with the amount of C02 that must be eliminated, things sensed by the apneustic and the pneumotaxic centers in the pons (a part of the brain). If this centers are damaged/altered physically, thermally or chemically they may increase/decrease the respiration in an abnormal way.
What happens when you decrease the temperature of a gas?
I think you meant what happens to the gas particles when the temperature decreases. If the volume of gas is constant(eg in a fixed container), the pressure of the gas will decrease. If the gas is in a container with a variable volume(eg. balloon), the volume of gas will decrease.
Long term athletic training will cause a person to increase hematocrit?
No, their hematocrit will decrease. Though they may gain RBC, their plasma volume will have a greater increase in volume, thus decreasing the hematocrit concentration.
