Answer:
No, If that was the case, then we should only be eating carbohydrates.
A fuel cell works like a battery. It consists of two electrodes where the reactions would occur and an electrolyte solution which allows for caharged particles to flow. In a fuel cell that uses hydrogen and oxygen as reactants. The hydrogen would enter the cell at the anode where oxidation would happen. So that the species that is formed in the anode side would be hydronium ions and electrons. The oxygen, on the other hand, would enter the cathode electrode where reduction occurs. The species that are produced in this side of the cell are water molecules. Together, the net reaction is called a redox reaction.
Molecular Biology
This field of study deals with everything related to macromolecules, thus, what you will need for molecular biology would be something you could get proteins and nucleic acids from. Among the choices, the DNA of a pig and a calf would be the most helpful.
Comparative Anatomy
Comparative anatomy is a field of study that focuses on any similarities or differences between the anatomy or structure of different animals or species in general. Among the options, having the limb structure of a pig and a calf would allow you to practice the field since you have a structure to compare.
Developmental Biology
In this field, your concern would be how species grow and develop. For you to properly observe the growth and development, you must have the embryo of a pig and a calf. Therefore, among the options, this is the correct piece of evidence for this field.
IN SUMMARY:
Molecular Biology - Both DNA of a pig and a calf
Comparative Anatomy - Both limb structure of a pig and a calf
Developmental Biology - Embryo of a pig and a calf
Answer:
By stopping the translation process, leading to a non-functional protein.
Explanation:
The genes of organisms are the protein-coding regions of the genetic material (DNA). They are expressed in a two step process to produce functional products e.g proteins that bring about certain phenotypes in the organisms. The two stages involved in gene expression are viz: transcription and translation.
During transcription, the gene (DNA) is transcribed into RNA molecule which is read in a group of three nucleotides called CODON during translation. Translation synthesizes an amino acid from each codon. A STOP CODON i.e. UUC, UUG and UUA signals the end of the translation process and brings it to an halt.
Hence, if a mutation i.e. a change in the nucleotide sequence, causes a stop codon to be produced during the expression of Lucy's ADA gene, the stop codon will signal the end of the translation process. Because the ADA protein was truncated, it will be non-functional i.e. not work in Lucy's body.
Answer: skin rashes or spread to the joints and blood. In Men: Discharge from the penis, swollen testicles. In Women: Vaginal discharge, pelvic pain, spotting.
