Answer:
The correct answer will be option-B.
Explanation:
Deoxyribose nucleic acid or DNA is the genetic material of the organism which is made up of nucleotide monomer. The structure of DNA is made up of two strands of nucleotides coiled in a helical structure thus providing a double-helical shape to the structure.
Each nucleotide of a strand is composed of a five-carbon sugar, phosphate group and nitrogenous bases. These molecules are arranged in anti-parallel fashion in DNA which provides the polarity to the DNA strand. One strand is read from the 5' to 3' direction whereas another form 3'to 5' direction.
Thus, Option-B is the correct answer.
Because they take up both parts of traits so that makes it group to similar organisms
Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.
DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.
In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called <u>emulsification.</u>
<h3 /><h3>What is emulsification in the digestive system?</h3>
Fat emulsification is the process of increasing the surface area of fats in the small intestine by grouping them into small clusters. Large lipid globules are split up into a number of smaller lipid globules. In the chyme, these tiny globules are widely dispersed rather than aggregating into larger groups. Hydrophobic compounds include lipids. Bile salts, are present in bile and have both hydrophilic and hydrophobic sides.
Due to the fact that lipases can only effectively act on lipids when they are broken down into small aggregates, emulsification is crucial for the digestion of lipids. The lipids are converted into fatty acids and glycerides by lipases.

Answer:
In a stable population, if all the other factors are equal then the birth rate should be equal to the death rate in order to maintain the stability.
Explanation:
The birth rate is described as the number of births taking place in an area per year. Death rate is described as the number of deaths taking place in an area in a year.
In order to maintain a stable population, the birth rate should be equal to the death rate. If there are more number of births than the number of deaths, then it would mean more competition for resources like food, water etc.
