Plants often photosynthesize during the day when they are exposed to sunlight. Hope this helps!
RNA and DNA are both types of nucleus acids. In their names long names, they both have the words “nucleic acid” in them. Nucleic acids are composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus.
Answer: The correct answer to the question is option WHEN GLUCOSE LEVELS ARE LOW AND LACTOSE IS PRESENT.
Explanation: To start with,Lac operon can be simply defined as a part of the DNA that is under the part of the DNA is manipulated and controlled by the same promoter,they can be found in some prokaryotic cells giving room for regulation over excess synthesis of protein.so simply put,these specific segment of the DNA binds with the segment of the polymerase of RNA so that transcription of the mRNA from the operon genes will be achieved.
Lac operon is also known as lactose operon, it is seen in some enteric bacteria like e.coli where they play a crucial role in coding of genes for those proteins that function in moving lactose into the cystocel and digesting it to form glucose that is used for energy generation. These lac operon are are most active when glucose levels are low and lactose is present,with the low level of glucose, the lac operon can be transcribed to a high level,this is to ascertain that the bacteria only gets to activate the lac operon and can only make use of it,that is using lactose when all the preferred energy source from glucose has been exhausted.
Operational risk management is a continual cylic process that involves assessment of risk, risk decision making and execution of risk controls. it is a five step process and it is often used in planning. the five steps include identifying the hazard. hazard is anything with the potential of causing harm. the second step is assessment of hazard. this is followed by making risk decisions and fourth step execution of risk controls and finally supervision.
Answer:
The main difference between Prokaryotic and Eukaryotic cell is that, eukaryotes contain membrane bound organelles like nucleus where as prokaryotes do not. The genetic material is present at the center and is called nucleoid in prokaryotes.
Explanation:
Example of prokaryotes include bacteria and archea bacteria. Examples of eukaryotes include plants and animals. Prokaryotes lack organelles such as mitochondria, endoplasmic resticulum and lysosomes which are present in eukaryotes. Both the groups contain ribosomes but its 70s ribosome in prokaryotes and 80s ribosomes in eukaryotes.
