Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.

Answer

The correct sequence is given below.

Explanation:

A. NAD+ (It recieves electrons directly from substrate in glycolytic as well as Citric acid cycle reactions)

B. Oxidoreductase (It is present as complex I termed NAD+-CoQ oxidoreductase. It receives electrons from NADH)

C. Quinone (It is present as Ubiquinone in complex III of Electron transport chain. It receives electrons from NADH and FADH2)

D. Terminal oxidase (It is complex IV of electron transport chain termed as Cyt c oxidase)

E. Oxygen (It is the final acceptor of electrons and gets reduced to water)

Halophiles of Archaea domain

Explanation:

The Archaea are characterized as single cells. They can exihibit both the autotrophic and heterotrophic mode of nutrition. Their cell walls do not contain peptidoglycans but contain pseudo-peptidoglycans etc. Their environmental conditions also need to be known to give a definitive identification and also are their organelles membrane bound.

What does it mean if a population is in Hardy-Weinberg equilibrium? Be specific.

Andrej [43]

Answer:

The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.

It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.
