Answer:
A scientific theory refers to the possible explanation of the natural event. It can be tested repeatedly and can be verified by anyone with the help of predefined sets of protocols and scientific experimentation.
Similarly, Darwin proposed the idea of natural selection as the mechanism of evolution.
Various experiments in labs, as well as observations made under natural conditions, proved that natural selection plays a major role in the evolution.
Examples may include industrial melanism of peppered moths, long neck of Giraffe, different shapes and sizes of beaks of Darwin finches et cetera.
This is why natural selection is considered a theory now.
Answer:
It is a fact and not a theory
Explanation:
A scientific theory is some natural phenomenon that has been tried and tested several times and backed by logical and testable observations and hypotheses in a way that in future anyone can test it. It is not a guess or hunch but a concept explained with logic and backed by solid unvarying proofs.
In case of biological evolution, observations have been made and tested several times so that no more further testing or trying is required. Hence, by this logic evolution can be considered as a fact but it can not be considered as a theory.
Answer:
Ther RNA polymerases (abbreviated as RNAPs or RNA pols), represent a group of conserved enzymes that synthesize RNA from DNA templates
Explanation:
These enzymes are used to synthesize different RNA species such as, amon others, messenger RNA (mRNA), transference RNA (tRNA), noncoding RNAs (ncRNAs), etc. During the gene transcription, the RNA pol is used to produce a mRNA molecule that subsequently is translated into protein
Answer: By definition, RNA polymerase or ribonucleic acid polymerase is a multi-subnunit enzyme that catalyze the process of transcription where an RNA polymer is synthesized from a DNA template.
Explanation:
RNA polymerase are highly conserved in evolution among eukaryotes, bacteria, archea and some viruses. Bacreria and archea has a single RNA. RNA polymerase are considered as molecular motors because of their stepwise movement on DNA. They are also central to biology information flow since they catalyzed templated polymerization reaction.
c. solutes to move into the cell.
b. water to move out of the cell.
d. solutes to move out of the cell
Answer:
The correct answer is c. consume two ATP molecule
Explanation:
Glycolysis is the process in which glucose is partially breakdown into two pyruvate molecules. Glycolysis is divided into two-phase the first phase is the preparatory phase and the second phase is the payoff phase.
In preparatory phase energy is consumed and the formation of two molecules of glyceraldehyde 3 phosphate(triose phosphate) takes place with the consumption of two ATP, therefore, this phase is called energy investment phase.
These two ATP are consumed when fructose 6 phosphate converts into fructose 1,6 bis-phosphate. Therefore, the right answer is c.
