The maximum time a person could listen to a sound of 87 decibels is: 8 hours
<h3>Meaning of Decibels</h3>
Decibels can be defined as the unit used by scientists to measure sound level.The values of Decibel ranges from a very low value to a very high value and the higher we get the more dangerous it is to our human ear.
In conclusion, The maximum time a person could listen to a sound of 87 decibels is 8 hours

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.
There is a 1:4 chance of getting JjQq. The parent JjQq can produce four genotypes: JQ, Jq, jQ, and jq. the parent JJQq can produce two genotypes: JQ and Jq. When we do a punnett square:
JJQQ, JJQq, JjQQ, JjQq,
JJQq, JJqq, JjQq, and Jjqq
There are two JjQq.
Two out of eight is one out of four.
Just like other cells, the part of the bacterium that is able to interact with its outside environment is its cell membrane. Generally, the main function of the cell membrane is for barrier and protection. This decides which molecules will be allowed to permeate or not. Hope this helps.
Anaerobic means with out oxygen
