Finding the increase in fresh mass can be unreliable due to variability in water content, which can fluctuate significantly based on environmental conditions, handling, and timing of measurements. Fresh mass can also be affected by factors such as dehydration or moisture absorption, leading to inconsistent results that don't accurately reflect the actual growth or biomass increase of the organism. Additionally, fresh mass does not account for the dry mass, which provides a more stable measure of biomass that is less influenced by these external factors.

Why is finding the increase in fresh mass not a reliable way to measure plant growth?

Measuring the increase in fresh mass is not a reliable indicator of plant growth because it can be influenced by factors such as water content and environmental conditions, which do not directly reflect the plant's biomass or health. Fresh mass can fluctuate significantly due to hydration levels, making it difficult to assess true growth over time. Additionally, it doesn't account for the composition of the plant tissues, such as the balance between roots, stems, and leaves, which are crucial for understanding overall growth and development.


Do you increase or decrease in mass?

you increase or decrease mass by taking the mass out


Why does saltwater have more density than fresh water?

Saltwater has a higher density than fresh water because the presence of salt particles increases the mass of the water without significantly affecting its volume. This increase in mass per unit volume results in a higher overall density for saltwater compared to fresh water.


How is the process of finding the mass different from that of finding the mass of a liquid?

Liquids weight less. Easier to drink.


What will happen if you increase the mass of an object what will the potential energy do?

If you increase the mass of an object, the potential energy will increase.


What is the increase in land mass by ice in Antarctica?

Ice does not increase land mass.


What was wrong with helmonts conclusion that when plants grow their increase in mass comes from water?

Increase of mass from water. Actually increase in mass is the result of increase in organic matter instead of water.


What is the formula for finding the mass of a cylinder?

Can heat increase mass?

No, heat does not increase mass. Heating an object can increase its internal energy and cause it to expand, but the total mass of the object remains the same.


Does the mass of water increase when you add copper sulfate?

The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.


Finding the mass of a rectangle?

you weigh it


Why is the density of sea water greater than fresh water?

Sea water has a higher density than fresh water due to the dissolved salts and minerals present in it. These dissolved substances increase the mass of the water without significantly changing its volume, resulting in a higher density compared to fresh water.
