Image result for The chromosome of a bacterium
The bacterial chromosome is one long, single molecule of double stranded, helical, supercoiled DNA. In most bacteria, the two ends of the double-stranded DNA covalently bond together to form both a physical and genetic circle. ... coli, a bacterium that is 2-3 µm in length, has a chromosome approximately 1400 µm long.Answer:
Explanation:
The orange dye moves independently of purple dye is true and concentration gradients exist that drive diffusion of both dyes is also true.
There is a net movement of orange dye from side A to side Only before equilibrium is reached so it is true.
Purple dye moves only from side B lo side A is false.
There is no net movement of purple dye is true.
What is diffusion?
The net movement of anything from a location of higher concentration to a region of lower concentration is known as diffusion. A gradient in the Gibbs free energy or chemical potential drives diffusion. As in spinodal decomposition, it is possible for molecules to diffuse "uphill" from a region of lower concentration to one of higher concentration.
Why does diffusion happen?
The molecules' kinetic energy causes random motion, which causes diffusion. This process happens in simple diffusion without the help of a transport protein.

Answer:
When a meal is put into the mouth, enzymes such as salivary amylase starts the digestion of Carbohydrates.
When the food is swallowed,Stomach enzymes containing pepsin and Hcl starts in the digestion of Protein.
The food then moves Into the duodenum which is a part of the small intestine. The protein is then again acted on by trypsin to form amino acid polypeptides.
Digestion of fats and oil starts here too and it is aided by bile which is produced by the liver and secreted by the gall bladder. Pancreatic juice which contains amylase and lipase acts on the starch and lipids respectively for further breakdown into glucose and glycerol respectively.
Nutrient and water reabsorption takes place in the large intestine the waste is expelled as faeces through the rectum.
