-DNA is double stranded,RNA is one stranded
-DNA contains the following nitrogenous bases:Adeninde Guanine Timine Citozine while RNA contains Adeninde Guanine Citozine and Uracil
-DNA function is to contain the information for manufacturing proteins while there are many types of RNA with whole different jobs for example:messanger RNA(mRNA) it coppies a sequence from the DNA strand and takes it to the ribosome in order to be translated as the order for placing aminoacids in the polypeptide strand;transport RNA(tRNA) it is a short RNA strand containing up to 100 nucleotides it takes aminoacids to the ribosome so the polypeptides strand can start to be manufatured from aminoacids in an order inscripted in the mRNA.
Photosynthesis is the process by which plants use the sunlight as a form of energy by converting carbon dioxide to make organic compounds that are necessary for growth.
In the first two stages of photosynthesis, the enzymes of the light-dependent reactions are activated by light and oxidation occurs, yielding oxygen gas and hydrogen ions. The hydrogen ions are used in the electron transport chain and are passed through the thylakoid. The electron transport chain results in the catalyzed reaction of adenosine diphosphate, or ADP, to adenosine triphosphate, or ATP, which is a source of chemical energy.
Later on in the Calvin cycle, the enzymes are important for the production of a three-carbon sugar, then a six-carbon sugar. There are three phases of the cycle that are powered by ATP and nicotinamide adenine dinucleotide phosphate, or NADPH. Being that the Calvin cycle is a metabolic pathway, the carbon compounds produced in the cycle are an important energy source that are used to make organic compounds used by the autotroph.
Anaerobic respiration in yeast (Saccharomyces cervisae) is also called alcoholic fermentation
C6H12O6--->2C2H5O+2CO2
Ethanol can be used as a disinfectant.
Ethanol can also be present in beverages.
Answer:
Without oxygen, life on Earth would not exist as we know it. It has provided the supercharged air that has fuelled an explosion in the diversity and size of all living organisms, from the smallest shrimp to the biggest dinosaur
"B. organisms that use the same resource" is destined to cause the most competition between those organisms, since resources are scarce and almost always limited.
