Answer:
100,000 years
Explanation:
A photon of light takes only eight minutes to get to the Earth from the surface of the Sun. But it can take 100,000 years from the core of the Sun to get to the surface. Where it bursts out and flies at the speed of light.
It starts with the cells<span>, followed by the tissues, then the organs, and ending with the organ .</span>
Answer:
Biocatalyst or enzyme
Explanation:
The Lactose is a disaccharide sugar or carbohydrate found in the milk and the milk products.
The breakdown of the lactase is very difficult but the presence of a protein molecule called lactase-phlorizin hydrolase or lactase makes the breakdown of the lactose int galactose and glucose easy.
Such protein molecules which increase the rate of reaction are called enzymes and since the breakdown of lactose is a biological process, therefore, the enzymes are also known as the enzymes or the biocatalyst they increase the speed of the reaction.
Thus, Biocatalyst or enzyme is the correct answer.
Answer:
A promoter and a start codon are similar in that both are sequences of Nucleic acid that are required to start important processes, and both determine the sites where the process will begin. The key differences are that the promoter is needed to start transcription and the start codon is needed to start translation. Also, the promoter is a DNA sequence only, and the start codon is a sequence found within a(n) mRNA .
Explanation:
The promoter is the sequence of DNA that serves as a binding site for RNA polymerase. The RNA polymerase is the enzyme of transcription. Promoters are required to start the process of transcription. Transcription is the process of making RNA copies of the DNA template strand.
The start codon is the first codon in mRNA that is translated during protein synthesis. The start codon marks the start of the protein-coding region of the mRNA. Binding of aminoacyl tRNA with complementary anticodon to the mRNA start codon begins the process of translation.
