Explain why viruses are not considered to be living.
viruses are not considered to be living because they lack cells and cannot reproduce on their own. although viruses contain DNA, they do not have a cell membrane, cytoplasm, ribosomes, or other organelles. they also need to use the cells of living organisms in order to replicate.
DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.
<h3>
What is DNA Sequencing ?</h3>
DNA Sequencing is a technique to determine the bases, nucleic acid sequence in the DNA. It is important to know the functions of genes, coding and non-coding part of proteins, identify the diseases, effectiveness of drug delivery etc.
<h3>
What is Land plants and Stonewort ?</h3>
Stonewort is commonly known as Chara . It is a freshwater green algae which comes from the Charophyta division. Fossils of Charophytes shows that Stonewort is a type of algae which is 470 million years old.
Thus from the above conclusion we can say that DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.

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.
Answer:
109,440 beats per day
Explanation:
75 times 60 (the amount of minutes in an hour) equals 4,560
456p times 24 (the amount of hours in a day) equals 109,440
Yes very true because we are not bacteria
