The biological levels of organization start with the atom, which is the smallest unit of matter. Take two or more of the most fundamental units, atoms, to form molecules. Molecules that are biologically significant are called macromolecules. One example of a macromolecule is deoxyribonucleic acid (DNA). DNA contains the basis for the structure and functions of all living organisms. The succeeding levels of organization of living things are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and the biosphere.
Carbohydrates glycaemic index (GI)
Glycemic index estimates
carbohydrates containing food based on how they increase the glucose in the
body. Foods are rated by comparing them to a reference food. Foods with high glycaemic
index increases blood glucose than foods with average or low glyceamic index. When taking foods with high GI, low GI foods
should be combined with it in order to balance the meal. Examples of low GI
foods are corn, most fruits, and yam. Medium GI foods include pita bread and
whole wheat. Puffed rice, instant oatmeals are examples of foods with high GI.
True since some of the input energy is turned into heat energy, which is then lost in the environment. This is why input work is never equal to output work, unless the problem is set in a 'perfect world'.
Oxygen is required for cellular respiration, it is an aerobic process. When no oxygen is present, the anaerobic process(a process that doesn't require oxygen) called fermentation begins creating ATP in smaller amounts. In cellular respiration, Oxygen is used to move electrons through the electron transport chain, and remove excess hydrogen and electrons in the form of water,
Watson and Crick described it well in their published work on DNA and its structure. ... This understanding of the structure of DNA is particularly important because it led to the realisation that if there is an adenine on one side of the pair, then the other base must be thymine.
