Charles is an engineer who is evaluating a prototype of an artificial heart. He should notice the prototype missing is : a structure that would divide the hollow heart into chambers to separate oxygenated blood from deoxygenated blood.
Answer:
If the hot-spot theory is correct, the next volcano in the Hawaiian chain should form east or south of the Island of Hawai'i. Abundant evidence indicates that such a new volcano exists at Lö'ihi, a seamount (or submarine peak) located about 20 miles off the south coast.
Answer: 31,000 meters (m) or 31 kilometers (km)
Explanation:
6,000 meters + 4,000 meters + 12,000 meters + 8,000 meters=31,000 meters
Simplified explanation: 6+4+12+8=31
Answer:
The same gene encodes both proteins by using different combinations of exons in the pre‑mRNA via alternative splicing.
Explanation:
According to the question, two different proteins (one with 56 amino acids and the other with 82 amino acids) are found to be encoded by the same gene. This is possible due to a process called ALTERNATIVE SPLICING.
Alternative splicing is a phenomenon whereby the protein-coding region of a gene called EXON is manipulated in such a way that variety of proteins emanate from a single gene. This manipulation includes the removal or inclusion of EXONS in the gene, so as to give rise to different combinations of mRNA, hence, different proteins will be translated from the different mRNA from the same gene.
In this case, exons were removed from one mRNA to have lesser amino acids (56) in the translated protein while exons were included in the other mRNA to have more amino acids (82).
