Ans. (4). protein synthesis.
Protein synthesis can be defined as a process that involves formation of polypeptides or proteins by using information present in DNA. It is divided into two steps, transcription and translation.
During transcription, DNA is transcribed into mRNA and information present in DNA is transferred to mRNA as codons. Codons represent triplet of nucleotides and each codon codes for a specific codon.
Translation involves formation of protein, during which amino acids are added to the growing polypeptide chain with the help of codons.
The given diagram represents process of translation. Thus, the correct answer is option (4).
Answer: A (ATP only)
Explanation:
Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.
Answer is ATP only
Answer:
A, B, C
Explanation:
Freshwater wetlands are defined as the lands which have natural supply of water for the whole season due to geological or ecological factors such as tidal flows, connections with groundwater or flooding rivers.
There are three main types of freshwater wetlands swamp, marsh and bog.
A Swamp are able to support tall shrubs, tress, herbs and mosses to grow . These are covered with floodd water or gently flowing water and waterlogged soils prevent woody debris to decompose completely.
Marsh is found near lake, tidal water or rivers and remain flooded periodically. Marsh are the grassy areas covered by shallow water and help to overgrown with coarse grasses, rushes and sedges.
Bog is defined as an area where moss or mots decomposes slowly and form peat . They are characterized by acidic waters, a floor covered by a thick carpet of sphagnum moss and spongy peat deposits. they are generally found in northern climates which support precipitation of water.
Hence, the correct answer is A, B, C.
