. Chemistry helps sustain bacteria by protecting the bacteria from outside organisms in the environment out and keeping the bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment

The biological approach has shown to be one of the most scientific perspectives in psychology. When explaining human behaviour‚ the biological approach focuses on the role of genes‚ inheritance and biological processes‚ claiming that these are the things which determine behaviour. Additionally‚ the nervous system also plays an important role in explaining human behaviour.

Scientists can only guess at the probability in evolution of the eye being formed; there are so many variables that a close number would be incalculable. The eye is an extraordinary part of the human body; most people agree that is the most important sensory organ. The eye sends messages

Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water‚ it is on the outside of the cell‚ the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals

A protein is a Biological polymer made up of as different amino acids joined by peptide bonds. A protein is formed by amino acids which are the basic building block of a protein components of an amino acid include a :C-carbon atom‚ H-Hydrogen atom‚ H3N+ - Amino Group‚ COOH- - Carboxyl Group‚ R- this group varies from amino acid to amino acid. There are 20 amino acids‚ each differing in its R group. Two examples are: Glycine‚ its R group being H(Hydrogen) and Phenylalanine its R group being CH2 (Carbon

The Biological Importance of Water! The ultimate importance of water is none other than the fact that life cannot exist without it. Water being the major component of our body cells‚ typically making 70-95% of it‚ constructs the body mass with approximately 80% being water. Humans are not the only ones who contain the valued material but other creatures like the jellyfish hold 96% of water as their body mass. The structure of the water molecules enables it to have extreme properties that are
