__________ helps organisms transport nutrients.
The soil protects this area from fire heat ex: Chamise, Trembling Aspen, Paper Birch, scarification: heat stimulates certain seeds to germinate, following fire ex: jack pine, loblolly pine, serotinous cones: jack pines and lodgepole pine have cones that remain viable for 25-75 years. Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Get an answer.

Plant kingdom, Plants without seeds, Characteristics of seed plants, Roots, stems, and leaves. Reproduction in seed plants. In the case of active transport, the proteins are having to move against the concentration gradient. For example the sodium-potassium pump in nerve cells. Na+ is maintained at low concentrations inside the cell and K+ is at higher concentrations. The reverse is the case on the outside of the cell. A large part of the mass of most organisms is simply water. In human tissues the percentage of water. ranges from 20% in bones to 85% in brain cells. The water content is greater in embryonic and young cells. and decreases as aging occurs. Diffusion is the net movement of a substance (liquid or gas) from an area of higher concentration to one of lower concentration. You are on a large (10 ft x 10 ft x10 ft) elevator. An obnoxious individual with a lit cigar gets on at the third floor with the cigar still burning. The positively charged sodium ion. (Na+) binds to oxygen, while the negatively charged chloride ion ( Cl-) attaches to hydrogen. This makes a. very stable “salty” water molecule. This property of water allows for the transport of nutrients vital to life in animals and plants. A drop of rainwater falling through the air dissolves atmospheric gases. When rain reaches the earth, it. affects the quality of the land, lakes and rivers.

Proteins are suspended in the inner layer, although the more hydrophilic areas of these proteins stick out into the cells interior as well as the outside of the cell. These integral proteins are sometimes known as gateway proteins.
