Answer:
Option C, move toward the ground state
Explanation:
When electron of an element move from a region of ground state to a region of high energy, it absorbs certain amount of energy. Now, when this electron starts moving from its excited stage to its ground stage it emits energy in the form of eigen states that vibrates with certain frequency just like the vibration of violin.
A spectrum is a distributed set of frequency and wavelength which corresponds to these eigen states
Hence otpion C is correct
personality
RNA
parents
Asexual reproduction
Mitosis
Replication
The process that can produce a large number of offspring is asexualreproduction, which is present in the second option. Asexualreproduction does not involve any genetic changes and produces identical offspring.
There are two types of reproduction: asexual reproduction, which includes binary fission, and sexual reproduction, which includes genetic diversity due to the meiosis process and genes crossing over. Asexual reproduction does not take as long as sexual reproduction in offspring, as evidenced by bacteria and other organisms. Asexual reproduction produces a large number of offspring in a short period of time with no genetic diversity from the parents as no sex cells or gametes are involved.
Hence, the process that can produce a large number of offspring is asexual reproduction, which is present in the second option.

#SPJ2
Answer:
The correct answer would be an option B.
Asexual reproduction is a reproduction in which offspring are produced from a single parent.
It does not involve fusion of gametes and crossing over due to which the offspring contain identical genome as that of parents.
This reduces the genetic diversity in a population due to which all the organisms of a population are at equal risk of extinction under unfavorable conditions such as high temperature, antibiotics, change in pH of surrounding medium et cetera.
Thus, the disadvantage of asexual reproduction is the lack of genetic diversity due to which a single antibiotic is able to kill millions of genetically identical bacteria.
B.deoxyribose
C.phosphate group
D.nitrogenous base
I believe the correct answer is B. Deoxyribose
The nucleotide of a DNA is slightly different to that of RNA due to an addition of a hydroxyl (OH) on the sugar molecule on the RNA nucleotide located on position 2 of the nucleotide.
The DNA and RNA molecules are almost similar.
They both have a nitrogenous base on position one. The nitrogenous base can be one of the 5 bases Adenine, Cytosine, Guanine or Thymine which can be coded by their alternate Uracil in the right places. They are considered to be the building blocks of the DNA and RNA molecules.
Located on position 5 of the nucleotide of both in RNA and DNA is the phosphate group. It has important functions including forming part of an ATP molecule to provide the body with the required energy. They also activate proteins through a process called phosphorilation for example in the cAMP cycle they activate protein kinases.
On the second carbon position there is a ribose sugar. It has only one oxygen molecule linked to each one of the 5 carbon atoms. On the second carbon position, the oxygen molecule is bound to a hydrogen atom forming a hydroxyl (OH). It is only in the RNA that the ribose sugar exists giving it its name; Riboneucleic acid.
The prefix deoxy- means that lack of oxygen. That is where the name deoxyribonucleic acid (DNA) comes from. On the second carbon position of the nucleotide is where there is lack of the oxygen molecule that usually binds to the carbon and hydrogen molecules leaving a hydrogen only bound to the 2nd carbon position. This sugar is only found in the DNA molecule. This small lack of an oxygen bound to the hydrogen allows specific enzymes to be able to identify the difference between a DNA molecule and an RNA molecule.

Difference between the two, DNA and RNA, is that DNA comprises of deoxyribose sugar while RNA comprises of the ribose sugar.
Further Explanation:
DNA and RNA are known to be the most vital molecules in the field of cell biology and is responsible for storing as well as reading the genetic information which basically underpins all life. They are both known to be linear polymers comprising phosphates, sugars, and bases.
DNA or deoxyribonucleic acid and RNA or ribonucleic acid are basically polymers comprises of monomers which are called nucleotides. A molecule of RNA comprises of 5 carbon sugar-phosphate associated with one of the four nucleic acid bases, namely, cytosine, guanine, uracil, and adenine. RNA comprises of a ribose sugar, with the hydroxyl modifications. RNA comprises of only one strand and is also known to be shorter as compared to DNA molecule. As RNA comprises of a ribose sugar, it is known to be more reactive as compared to the molecule of DNA.
In a molecule of DNA, the sugar is lacking the hydroxyl group at the 2’ position and the thymine base is observed instead of uracil. DNA comprises of two strands and it is arranged in a double-helical structure. DNA is considered to be more stable as compared to the RNA molecule due to which, it is useful for the DNA molecule to carry the responsibility for storing the genetic information safely.

All of the following such as DNA sequencing, PCR, electrophoresis, and DNA hybridization are used in molecular techniques for genetic analysis.
Genetic analysis is the science of identifying, studying, and diagnosing genetic variations in an organism's DNA. The most common molecular techniques used in genetic analysis include DNA sequencing, PCR, electrophoresis, and DNA hybridization.
All of these techniques share the underlying theme of genetic analysis, with a focus on the analysis of genetic variations in DNA. DNA sequencing is used to read and interpret the genetic code, while PCR is used to amplify specific DNA sequences, enabling their detection.
Electrophoresis is a technique that separates DNA fragments based on their size, charge, and other physical properties, and DNA hybridization is a technique that detects and quantifies specific DNA sequences by binding them to complementary DNA probes.
