BIOLOGY IS COOL

here is where you will be told about information on bullets A-J. From Ribosomes to Midochondria. From chlorophyl to nuclei.

 

Science Beakers

A) Cells are enclosed in semipermeable membranes which regulate their interactons with their surroundings. A semipermeable membrane allows some molecules to pass through the nucleus pores and not others. Most cells are subject to osmosis because they are surrounded by water solutions. An Isotonic solution is where the concentration of disolved substances is the same as the disolved substances inside the cell. In a hypotonic solution the concentration of disolved substances is lower then the disolved substances inside the cell. However In a hypertonic solution the concentration of disolved substances is higher then the concentration of disolved substances inside the cell.

 
B) An enzyme is a substance that alters chemical change without changing itself. In order for an enyme to survive they need a constant temperature of 98.6 degrees fahrenheit. They also need a pH balance of 7.000. They depend on ionic conditions to be able to operate properly.

C)Prokaryotic cells are generally smaller and more simple. Prokaryotic cells are structuralley simple because of their size.(the smaller the cell the greater the surface-to-volume ratio) Eukaryotic cells are much larger. They rrequirre a variety of special organelles to carry out metabolism, providde energy, andd transport chemicals throughout the cell. Eukaryotic cells are found in, animals, plants, algea,protozons, and fungi. Prokaryotic cells are found in bacteria(enbacteria and acchaebacteria). A virus is a bundle of genetic material; DNA, RNA. Carrie in a shell called the viral coat or capsidd. Some viruses have another layer called the envelope. There are thousands of diffferent viruses. Thay are all very small. A viruses structure is more rigid and less round.
