Answer: Climate change is as well a great danger to the deciduous forest. When other types of chemicals are released in the air the wind, rain, clouds and temperature. This can ambush chemicals and has the ability to move them across the forest causing different weather patterns. In drastic conditions this can become permanent.
The structure of the plasma membrane;
The plasma membrane is composed of a bilayer of phospholipids. A molecule of phospholipid consists of two fatty acids and a phosphate group attached to a glycerol component. The fatty acid tails represent a hydrophobic region of the molecule, while the glycerol-phosphate head is hydrophilic. The phospholipids are arranged into a bilayer formation with the hydrophilic heads pointing to the outside and the hydrophobic tails pointing toward the inside. The plasma membrane is a barrier to most molecules. In plants, fungi, and bacteria, the membrane deposits cellulose or other polysaccharides on the outside of the membrane to create a cell wall, which it provides support to the cell.
Embedded in the phospholipid bilayer are various proteins and, in animals cells, cholesterol molecules. This mixture of molecules accounts for the fluid mosaic model of the plasma membrane, that is, a highly flexible lipid boundary impregnated with various other molecules.
The interactions of plasma membrane with the outside environment;
The plasma membrane is a selectively permeable membrane. Small molecules, like O2 and CO2, readily diffuse through the membrane. The movement of larger molecules is regulated by proteins in the plasma membrane. There are several kinds of these proteins. Channel proteins provide passage for certain dissolved substances. Transport proteins actively transport substances against a concentration gradient. The glycocalyx, consisting of the oligosaccharides from glycolipids, recognition proteins, and other glycoproteins, provides adhesion or
participates in cell-to-cell interactions. Receptor proteins recognize hormones and transmit their signals to the interior of the cell.
Various substances can be exported into the external environment by exocytosis. In exocytosis, substances are packaged in vesicles that merge with the plasma membrane. Once they merge with the membrane, their contents are released to the outside. In an opposite kind of procedure, food and other substances can be imported by
endocytosis. In endocytosis, the plasma membrane encircles the substance and encloses it in a vesicle.
A double circulatory system is composed of a <u>PULMONARY </u>circuit and a(n) <u>SYSTEMIC </u>circuit
Pulmonary circulation means where blood goes to lungs to get purified and exchange gases, i.e. CO2 is released into the lungs and oxygen is taken into the blood.
Systemic circulation is between heart and entire body, where oxygen is supplied to every cell of the body and CO2 is absorbed.
