D bucolic acid is history and rain stomach
Answer:
Which of the following is not part of the nucleotide structure?
a.
<h2>
Sulfate backbone </h2>
c.
Phosphate group
b.
Nitrogenous base
d.
5-carbon sugar
Explanation:
A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.
The question is incomplete as it does not have the options which are:
resistant
semisynthetic
synthetic
natural
Answer:
Semisynthetic
Explanation:
Antibiotics are the microbial compounds which are obtained from the micro-organisms which are found effective against the bacteria as they act by inhibiting the activity of the bacteria which ultimately kills the bacteria.
These antibiotics can also be distinguished based on their synthesis: natural, semi-synthetic and synthetic antibiotics.
The semi-synthetic antibiotics are the antibiotics which are obtained from the microbes but are modified artificially by making chemical changes to increase the effectiveness of the antibiotic and making the antibiotic as broad-spectrum bacteria.
Since the properties of the antibiotics provided in the question are similar to the semi-synthetic antibiotics, therefore, is considered semi-synthetic bacteria.
Thus, Semisynthetic is correct.
<span>Cells are basically the building blocks of all living things. There are actually trillions of cells in the human body!
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
I hope this helps you!! :)</span>
From the question you can immediately infer that it's either B or D, as A and C basically mean the same thing and it isn't anything related to a microscope. I can tell you now that you don't need an electron microscope to see cells, they're only required for the atomic level.
Therefore, the answer is B, as you can't see cells without a microscope but you only need a light microscope, not an electron microscope.
