When size of cell increases ,its surface to volume ratio decreases , control of cell activities become difficult , contact area with surrounding decreases .
The surface area-to-volume ratio is crucial for a cell's efficiency in exchanging materials with its environment. As a cell grows, its volume increases faster than its surface area, which can limit the ability of the cell to transport nutrients in and waste products out. A higher surface area relative to volume facilitates more efficient diffusion and cellular processes, which is why cells tend to remain small or divide when they reach a certain size. This ratio impacts overall cellular function and can influence growth, metabolism, and the ability to respond to environmental changes.
A cylindrical protist has a higher surface are to volume ratio. This is because of the physical properties of spheres (some rather complicated math proves that spheres hold the most volume for their area).
Not in absolute terms. Consider the volume of a feather duvet (or downie). But for a given substance, the mass and volume will be proportionate.
In terms of volume of water, the largest is Lake Baikal in Siberia. Siberia is in Russia. In terms of surface area the Caspian Sea is largest but it is not freshwater. Lake Superior is the largest freshwater lake by surface area.
Rainfall is expressed in terms of depth (in inches or millimeters) rather than volume (in liters or gallons) because depth measurement provides a more standardized and comparable way to quantify the amount of rain that falls across different locations and time periods. It allows for easier comparison and analysis of rainfall data without the need to account for variations in surface area or other factors that volume measurement would entail.
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
Let V=volume V^(1/3)=Side Length=S 6*S^2=Surface Area Surface Area=6*(Volume)^(2/3)
144pi sq
It would help to know why what!
To compare ratios, compare the products of the outer terms by the inner terms.
A cell's volume is the amount of material that can fit into the cell. A cell's surface area is the total amount of material that makes up the outside of the cell. The ratio of surface area to volume is the amount of surface area per unit volume of an object or collection of objects.

To use equivalent ratios to complete a table, first identify the ratio you want to work with. Then, multiply or divide both terms of the ratio by the same number to find equivalent values. For example, if the ratio is 2:3, you can find equivalent ratios like 4:6 (by multiplying both terms by 2) or 6:9 (by multiplying by 3). Fill in the table with these calculated ratios to maintain consistency throughout.
Ratios are often classified using the following terms: profitability ratios (also known as operating ratios), liquidity ratios, and solvency ratios.
To write equal ratios multiply both terms by the same number or divided both terms. For example, 2/ 9 is a ratio equal ratio will be 4/18. There is no difference between equal ratios and equivalent ratios.
To determine if two ratios are equivalent, you can cross-multiply the terms. For example, if you have ratios ( a:b ) and ( c:d ), you check if ( a \times d = b \times c ). If the products are equal, the two ratios are equivalent. Alternatively, you can simplify both ratios to their lowest terms and see if they are the same.
Divide the mass by the volume and express the answer in terms of "units of mass per units of volume" - in this case, grams per cm^3..
