It separates the internal contents of a cell from its external environment. Its structure is composed of a phospholipid bilayer that is hydrophilic on the outside and hydrophobic on the inside. The membrane also contains proteins and carbohydrates. 1. What is the structure of plasma membrane and what are its major lipid and protein components? The membrane is considered a mosaic of lipid, protein, and carbohydrate molecules. It resembles a fluid mosaic because lipids and proteins can move relat...

Describe the chemical composition of biological membranes? Biological membranes are bilayers of phospholipids with associated proteins and carbohydrates. What can never be energetically favorable in a biological membrane and therefore will not occur spontaneously? the flip-flop of phospholipids to the opposite leaflet Let's suppose an insect, which doesn't maintain a constant body temperature, was exposed to a shift in temperature from 60°F to 80°F. Which of the following types of membrane...

Griffiths (1928) mixed heat-killed 'S' bacteria with 'R' bacteria and injected a mouse with both types of bacteria. As a result, the mouse died and Griffiths obtained living 'S' bacteria from the dead mouse. How can you explain this phenomenon? -️️The DNA from the 'S' bacteria with the gene responsible for capsule formation was transferred to the 'R' bacteria when the strains were mixed. This gene transformed the 'R' bacteria into 'S' bacteria, allowing it to produce a cap...
