Answer:
The statement true of all proteins, carbohydrates and fats is that human body is able to synthesize them all.
The statement unique to proteins is that proteins are made up of instructions according to DNA.
Explanation:
Carbohydrates, Proteins and fats are macronutrients and required by body in larger amounts. All these macromolecules are made up of building blocks like proteins are from amino acids, carbohydrates from monosaccharides and fats from triglycerides. Human body can also synthesize these macronutrients. Like proteins can be synthesized by central dogma. Glucose can be synthesized by gluconeogenesis from glycogen and fats can be synthesized from acetyl-CoA and NADPH.
The proteins are made up by a process known as central dogma. The first step of central dogma is replication in which a replicated copy of DNA is produced in a cell. The second step is transcription for the production of messenger RNA from DNA. At last mRNA is used for the production of proteins on ribosomes.
Answer:
a) Ribosomes
b) Please find the justification for the answer in (a) below.
Explanation:
According to this question, Hepatitis C is a virus that causes liver disease by attacking the liver. However, a REDUCTION IN ALBUMIN, which is a protein that regulates oncotic pressure of blood in humans- a process necessary for the regulation of fluids in vessels of the body and tissue repair, has been found to have to do with liver disease.
Since ALBUMIN is a protein produced by the liver, which when diseased causes a reduction to the blood-albumin level, the organelle in liver cells that is most likely being affected by hepatitis C is the RIBOSOME. This is because the RIBOSOME is the organelle/site for PROTEIN SYNTHESIS in any cell. Hence, the ribosome organelle of the liver cells are responsible for synthesis of Albumin protein.
Hence, a diseased liver due to attack by Hepatitis C virus means an attack on the RIBOSOMES of the liver cells producing the protein.
Answer:
<em>The genotype of the mother will be Bb.</em>
Explanation:
A punnet square can be described as a diagram which is made to depict the outcome of a cross.
In the scenario discussed in the question, the genotype of the male parent will be bY. This is because he has the recessive black spots. As he is a male, he'll only have one allele for this gene.
In order to have one of spot design for each gender, the mother will have the genotype Bb.
The punnet square will be as follows:
b Y
B Bb BY
b bb bY
Answer:
Explanation:
A scientific researcher performs scientific methods to answer any natural process. The researcher will follow the protocol of a scientific method which includes: observe the natural phenomenon, ask related questions, suggest a hypothesis, perform the experiment and suggest answers.
In the given question if the researcher has to study about the flu virus, the possible questions he would ask will be:
1. The life cycle of the flu virus.
2. Effect of the virus on the life of an organism.
3. The mechanism used by the virus to replicate and to infect any organism.
4. Molecular mechanism of a virus.
