21. Which stage of aerobic respiration produces ATP and NADH and release CO2?
a Glycolysis
b. Krebs cycle
c Electron transport chain
d. Fermentation
stage of aerobic respiration produces ATP and NADH and releases CO2, which is the electron transport chain that is in option c, as the ETC has a role in the production of ATP in cellular respiration.
What is the significance of respiration in ATP synthesis?It plays an important role in respiration because it is formed by the oxidation of glucose or other organic molecules in the mitochondria of eukaryotic cells and in the cytoplasm. During respiration, glucose and oxygen are consumed, and carbon dioxide and water are produced, and then the mitochondria make ATP by taking the products of glucose.
Hence, aerobic respiration produces ATP and NADH and releases CO2, which is the electron transport chain that is in option c, as the ETC has a role in the production of ATP in cellular respiration.

What is the function of mRNA in the diagram above?
The function of mRNA in the diagram given above is carrying the genetic message from DNA to the ribosomes.
What is the function of mRNA?
The main function of mRNA has to work as the immedieter between the protein and DNA which has been utilised by the ribosome for the process of the direct synthesis of protein, and the function of tRNA has to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.
RNA has backbone and it has to made up of phosphate group which has been arranged in alternating form and the sugar known as ribose other than the deoxyribose present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.
Liquid consist of small range of order and the reason behind this is intermolecular attractive force which is very strong and due to this reason molecules are packed together tightly.
Therefore, The function of mRNA in the diagram given above is carrying the genetic message from DNA to the ribosomes.

Features are inherited characteristics or structures.
True or False
Answer:
It is true. The features or traits, as structure and functions, are inherited.
Explanation:
The structure and function of a living being are features or traits that come from information provided by the parents, so they are considered inherited traits.
The information related to the featrures of a living being is found in the DNA, which forms genes and chromosomes. In the context of sexual reproduction, this information is contained in the father's and mother's gametes, which is transferred to the offspring.
The structural and functional traits that are passed from parents to offspring are called hereditary, and constitute what is known as genetic inheritance.
