Nucleic acids are the biolmolecules which are responsible for carrying information from one generation of organisms to the other. There are two types of nucleic acid namely the deoxyribo nucleic acid (DNA) and the ribo nucleic acid (RNA).
The similarity between the DNA and RNA is that both act as the genetic material carrying genetic information in them. Both are made up of polynucleotide chain with the repeating units called the nucleotides containing a nitrogenous base, a pentose sugar and phosphate. The difference lies in the type of the sugar and nitrogenous bases present. In RNA, the sugar is a ribose. In DNA, the sugar is a deoxy ribose derived from a ribose sugar by the loss of an oxygen atom. The nitrogenous bases of DNA are the adenine, guanine, thymine and cytosine. Whereas, the nitrogenous bases of RNA are the adenine, guanine, cytosine and uracil. Also, DNA is a double stranded molecule with two polynucleotide chains, whereas RNA is single stranded.
The answer is A. macromolecules
There are 4 types of macromolecules; lipids, proteins, carbs and nucleic acids
Answer:
The correct answer will be- complex system.
Explanation:
A scientific investigation is performed to understand and explain the natural phenomenon using the scientific method.
An investigation is performed in one of the three ways: descriptive, comparative and experimental.
In the descriptive investigation, the investigation provides a descriptive account of any "complex system" by observing it when no prior knowledge is known. Therefore this method does not include the formation of a hypothesis.
Thus, complex system is the correct answer.
Phytoplanktons are also called microalgae. They are the foundation of the aquatic food web and the primary producers. They feed everything from microscopic to multi-ton whales. Thus, the answer to the question above is letter B. Provide basis of food chains.
