What is the difference between ratios and rates? - Socratic
2014年12月8日 · Both rates and ratios are a comparison of two numbers. A rate is simply a specific type of ratio. The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit. For example, in a room full of students, there are 10 boys and 5 girls. This means the ratio of boys to girls is 10:5. If we …
Surface Area to Volume Ratio - Biology - Socratic
The ratio between the surface area and volume of cells influences their structure and biology. Surface to volume ratio places a maximum limit on the size of a cell and can influence the environment in which an organism lives and gets nutrients.
Rates of Change - Algebra - Socratic
Rate of change is a number that tells you how a quantity changes in relation to another. Velocity is one of such things. It tells you how distance changes with time. For example: 23 km/h tells you that you move of 23 km each hour. Another example is the rate of change in a linear function. Consider the linear function: #y=4x+7#
What is a ratio of two quantities that have different units ... - Socratic
2018年2月27日 · A "rate" is a ratio involving a comparison of 2 quantities that have different unites of measurement. An example of this can be miles per hour or g/mL.
Rate of Reactions - Chemistry - Socratic
If [A] is decreasing at the rate of 0.1 mol•L⁻¹min⁻¹, [B] is increasing at the rate of 0.2 mol•L⁻¹min⁻¹. The rate of a reaction should be the same, no matter how we measure it. We must account for the stoichiometry of the reaction. So we divide the rate with respect to a component by its coefficient in the balanced equation.
How does surface area to volume ratio affect the rate of ... - Socratic
2015年10月21日 · More the surface area to volume ratio, more is the diffusion. Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time. Amoeba and some bacterias are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area. Where as humans …
How does surface area to volume ratio affect gas exchange?
2014年8月1日 · The surface area to volume ratio of a cell must be such that the cell membrane has enough surface area to adequately serve the internal contents (volume) of the cell, including the adequate exchange of gases. As the cell grows, its surface area to volume ratio decreases, reducing the rate of gas exchange. This is because as the surface to volume ratio decreases, …
How does surface area to volume ratio relate to photosynthesis?
2015年6月20日 · Surface area to volume ratio (SA:V) is important to photosynthesis because plants must balance their need for more surface area to collect sunlight with the fragile nature of the leaves and the rate of water loss. The equation for photosynthesis is "6CO"_2 + "6H"_2"O" → "C"_6"H"_12"O"_6 + 6"O"_2 A greater SA:V means more area for collection of sunlight and …
How do you find the rate of change of y with respect to x?
2014年9月23日 · The rate of change of y with respect to x, if one has the original function, can be found by taking the derivative of that function. This will measure the rate of change at a specific point. However, if one wishes to find the average rate of change over an interval, one must find the slope of the secant line, which connects the endpoints of the interval. This is computed by …
What does a 1:1 ratio mean? + Example - Socratic
2015年5月23日 · At the same time the ratio of the two different sized skids present is also #1:1# If you had to mix oil and water in a #1:1# ratio you would need to mix #1L# of each into a container that will hold at least #2L#. Similarly you could mix #3Tsp# sugar with #3Tsp# butter and that initial #1:1# ratio would result in a sticky sweet glob. Always use ...
