How many mL of 36N H2SO4 is required to form 1000 mL of 1N H2SO4?

Long before it was investigated by M. Hildebrand, plant chloroplast and eukaryotic DNA were known to contain plasmids.

"We have discovered plasmids in 5 of 18 diatom species surveyed. In several species, more than one type of plasmid is present. Several of the plasmids show similarity by hybridization previously characterized plasmids in Cylindrotheca fusiformis (J. D. Jacobs et al., unpublished data). Additionally, there is similarity between the plasmids found in C. fusiformis and chloroplast DNA in three diatom species. These results add to the evidence that the plasmids have features of mobile genetic elements." -

Question: Do plasmids naturally occur as circular DNA outside chromosome or they form the circular shape when they genetically recombine as a cloning vector with other DNA ?

Has it anywhere in your text book been mentioned that viruses are different from plasmids and can’t and do not contain plasmids? I know it is written that bacteria contain plasmids. But, does that mean “Viruses are devoid of plasmids”? Would you go a step forward of your text book as many scientists do?

The diameters of two pipes are 4 cm and 4.5 cm. What would be ratio of flow of water in those pipes?

Find the extreme values of x of the function f(x) = x^2 + x + 1 = 0 within the interval [-1, 1] .

Find the extreme values of x of the function f(x) = x^2 + x + 1 = 0 within the interval [-1, 1] .

You can often see that elderly people submit wrong answers to questions asked by school students and minors. They not only try to convince minors about their wisdom by putting labels like Professor, Dr., Senior Teacher, etc., but also argue on baseless grounds with someone who gives the correct answer. Furthermore, these people remain silent on critical scientific questions which require elaborate discussions and greater degree of knowledge. How to get rid of this? Don't they cause any harm to the mind of young learners?

What is the value of total binary operations of their best wishes?

Question on lattice energy....please help......?

What are the Born postulates in defining lattice energy of a stable molecule? How it approaches to define the forces in a covalent molecule?

What you are required to do is- only mention postulates as serial number (1), (2), (3), ...... etc. and then give a scientific derivation of equation(s), if at all exists, and to explain how they came in describing the forces in a covalent molecule. That's all. Thank you!

Two types of tissues are isolated from human body:-

Type 1 contains 19% collagen and type 2 contains 50% collagen.

Which type of tissue will be harder and conforming to a bone-like structure?

A cellular protein laking in tryptophan is produced by hydroxylation, glycosylation and di-sulphide bond formation in the body, and contributes to approximately one-third of the body protein. Can you name that protein?

The two adjacent arms of a square are reconstructed. One arm is made 5 cm smaller and the other is made 5 cm bigger. The rectangle thus formed has an area of 50 square cm. What was the area of the square?

While selecting a 9-member basketball team in school for the next game only a 9 years and 6 months old member is dropped from the team which played the previous game and a new member is selected in his place. By doing so, the average age of the team is increased by 2 months. What was the age of the new member selected for the next game?

If x and y are two positive real numbers such that x² + y² - 7xy = 0 ; then find the value of log(base 10) {(x + y)/3}.

Please note that without indicating the base of log , the problem is to find out the value of

log{(x + y)/3}.
