Photosynthesis produces oxygen gas by the reaction of sunlight and carbon dioxide. Every living thing living in an ecosystem requires oxygen to breathe and to survive.
Answer: The simplest way is to determine if a strain is mutant is observing morphology, growth rate, double time, etc but it is accurate if you can prove if the strain is deficient in one aminoacid or can't metabolize lactose, etc.
Explanation: A wildtype strain functions normally, for example, can metabolize as a carbon source, glucose, lactose and other sugars, can synthesize all the aminoacids requered for protein synthesis, etc. If a strain suffers a mutation and it is inheritable, the strain become a mutant. Since several mutations can be silent ones, only those that interfere with a process, can be assesed easyly.
For example, if you have several strains and put them in a lactose medium, but some of them cannot growth means that are lactose mutants. Those strains could carry a mutation in genes that encode lactose degrading enzymes or in regulatory genes of the lac operon, etc.
Most enzymes do in fact work on a single substrate in most cases, this is because of the enzyme - substrate specificity. Certain reactant molecules acting as substrates can only fit in the "lock" of particular enzymes and undergo a conformational change and result in Unique products to be released after the reaction has occurred.
Answer:
Phenotypes
Explanation:
'Phenotype' is just a fancy way of saying 'what an organism looks like'. Those words describe an organism's physical appearance and not its genetic makeup--that's its genotype.
You can remember it this way:
Phenotype
Physical characteristics/appearance
----
Genotype
Genetic makeup
Onion (Allium) and Banana (Musa) are both eukaryotes and both have cell walls.
