What is the difference between haloduric and halophilic organisms?
Halophilic organisms like being, and grow, better on places with high concentrations of salt while haloduric organisms can stay on places with high concentrations of salt but they won't grow (reproduce)...the just survive.
What organisms does phytonmining?
Plants are the organisms used for phytomining. If plants can absorbs the low concentrations of metals in soil, the metals can be concentrated in the biomass of the plants and then extracted from the plant material when harvested.
What roles do electrolytes play in osmoregulation?
Electrolytes are charged ions (Na+, Cl-, Ca2+, K+) that dissociate in water, meaning they are dissolved within water molecules being carried throughout your body and cells. This is creates concentration gradients within cells/tissues via osmosis and diffusion, from high concentration to low. This is vital in many animals becase too high electrolyte concentrations can cause cells to function abnormally (lysis, crenation) and the same with too low electrolyte concentrations. This is the reason homeostasis is important for maintiating the optimal balance/concentrations throughout an organisms body in order to maintain proper function of cells, tissues, organs, organ systems etc. Osmoregulation is pricisely this universal mechanism of constantly regulating water pressure/concentrations throughout an organisms body in order to survive. Its important to note, many organisms achieve homeostasis by different osmoregulatory mechanisms depending on their environment (teresstrial organisms, marine organisms, fresh water organisms...Aliens?) This is dependant on the electrolyte concentrations they are consuming via water from their enviornment. (remember we are made of roughly 68-70 % water)
What are 4 things that organisms must keep stable or balanced?
The process of an organism maintaining stability is known as homeostasis. Examples of things that organisms must keep balanced are temperature, pH, the concentrations of ions (such as calcium) and glucose levels.
What makes an organism more sronger or more effective?
The organisms ability to survive and be reproductively successful in the immediate environment.
What are osmotolerance organisms?
Organism which can withstand high concentrations of solute.
What is the difference between haloduric and halophilic organisms?
Halophilic organisms like being, and grow, better on places with high concentrations of salt while haloduric organisms can stay on places with high concentrations of salt but they won't grow (reproduce)...the just survive.
Why is diffusion possible in unicellular organisms not in multicellular organisms?
It is possible in multicellular but not effective .
What do you call microbes that can not survive except in the presence of high concentrations of salt?
You think probable to organisms called halophile.
What organisms does phytonmining?
Plants are the organisms used for phytomining. If plants can absorbs the low concentrations of metals in soil, the metals can be concentrated in the biomass of the plants and then extracted from the plant material when harvested.
What controls the concentrations of organic matter in soils?
Soil micro-organisms control the concentration of organic matter in the soil. Thus, fertile soils are full of soil humus and micro-organisms.
What is the process concentrations of harmful substances increase in organisms at higher tropic levels in a food chain known as?

How effective was bolling on each organism why?
It was completely ineffective. Organisms do not boll.

What is methane also known as?
Methane is called a marsh gas because it is formed by methanogenic organisms that can be found is marshes (thus concentrations can be found in marches).

Why is extra aluminium in the soil bad?
Aluminum is an abundant element in Earth's crust and is not "bad" for the Earth, although it may be "bad" for organisms in the biosphere in certain concentrations.
