HAHAHA. Are you in Biology this year and trying to figure out the answer of a question in a lab? I am doing the same thing. Sorry but no answer. I think it is from the air though maybe? That's what I found from researching
Plants get most of their mass from carbon dioxide.
Because it's on its period.
Nutrients in the soil.
The Air..
Gravity causes all types of mass movement. Mudflows, landslides, creeps, and slumps can all be causes by gravity.
Tree rings are the sign of the age of the tree. Each ring is laid down each year.
Slope Gradient
Tree roots tie in the soil and prevent erosion.
Hot air mass
because it does
a closed system will not gain or lose mass
Eggs soaked in distilled water will gain mass and appear dramatically swollen. Eggs in dilute salt solutions will gain mass, and even those in very concentrated solutions might gain mass. Eggs buried in salt or other dry media should lose mass.
no it doesnt gain mass at allIt can change the bio mass. But cannot change the mass of earth as it uses resources within earth
if anything it would be reasonable to expect it to lose mass.
Answer: Your frame size will become larger so you will gain weight, but not from muscle mass. You can gain muscle mass from exercise.
X-mass tree.
Assassinations are caused by political gain, financial gain, revenge
Yes, in fact, this is basically the main thing that helps you gain muscle mass.
A tree is not an isolated system. It gets nutritients from surrounding environment to grow and build its mass. A total mass of tree plus its environment is constant.
mass is a fixed quantity
Gravity causes all the types of mass movement. :P
