The correct answer is C.commensalism; parasitism
At first it is a commensalism relationship which becomes parasitic when the living cells get attacked.
Answer:
<u>Inheriteted/Beneficial</u>
Explanation:
<em>First drop down</em>: "Sickle cell disease is passed on from parent to offspring."
<u>Inheriteted</u>
<em>Second drop down</em>
A increased resistance to a bad thing (malarial parasites) would be <u>Beneficial</u>
Answer:
Polar
Explanation:
In a water molecule, the oxygen atom is bigger and has a greater pull on the electrons than the hydrogen atoms do. This makes the molecule polar.
Answer:
Thiamine pyrophosphate (derived from vitamin B1) is a coenzyme required for the activity of pyruvate dehydrogenase enzyme complex.
Explanation:
Pyruvate is the end product of glycolysis. During aerobic cellular respiration, pyruvate is oxidatively decarboxylated into acetyl CoA which in turn enters the Kreb's cycle. Oxidative decarboxylation of pyruvate is carried out by enzyme complex pyruvate dehydrogenase (PDH). The first step is simple decarboxylation and is catalyzed by pyruvate decarboxylase of the PDH complex.
The enzyme pyruvate decarboxylase and has a tightly bound coenzyme, thiamine pyrophosphate. Thiamine pyrophosphate is derived from vitamin B1. Lack of vitamin B1 in the human diet leads to beriberi that is characterized by an increased concentration of pyruvate in blood urine since oxidative decarboxylation cannot occur due to lack of the coenzyme thiamine pyrophosphate.
Answer: An error during transcription could produce a shorter protein or induce changes in the protein's sequence.
Explanation: Transcription is the process of single-stranded RNA synthesis from a DNA template (gene). During this process, RNA polymerase reads the DNA template and synthetize RNA, keeping the sequence. The RNA sequence will be reading later by ribosomes and protein will be produced. An error in transcription could produce changes in codons that are sequences of 3 nucleotides that determine aminoacids of the protein, and that would change protein folding and inactive it. Another possible result would be that error in transcription produce a premature stop codon that cause a shorter inactive protein.
