Introduction:
The viruses are small biological infectious agents that can replicate inside the cells of other living organisms only. They are simple particles that require a host cell to replicate and survive.

Answer to Problem 1TYK
Correct answer:
The host cells provide ATP (adenosine triphosphate),
Explanation of Solution
Explanation/Justification for the correct answer:
Option (d) is given as all of the above. The viruses cannot make their own ATP, nucleotides, amino acids, and ribosomes. The virus cannot synthesize their own proteins. The virus enters the host cell to survive. The host cell provides the energy (ATP) to the viruses inhabiting it. It also provides nucleotides for
Explanation for the incorrect answers:
Option (a) is given as nucleotides and amino acids. Host cell provides amino acids as well as nucleotides for viral growth and development. The entities like ATP and ribosomes are also provided by the host cell to the virus. So, it is an incorrect option.
Option (b) is given as ribosomes. Host cell provides ribosomes to the viruses that serve as the site for protein synthesis. Nucleotides, amino acids, and ATP are also provided by the host cell. So, it is an incorrect option.
Option (c) is given as ATP. The ATP is provided by the host cell to the viruses to carry out various cellular activities. Nucleotides, amino acids, as well as ribosomes are also provided by the host cell. So, it is an incorrect option.
Hence, options (a), (b), and (c) are incorrect.
Therefore, it can be concluded that the host cells provide energy, proteins, nucleotides, ribosomes, and amino acids to the viruses for their development and growth.

- Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to Aarrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forward

The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobinarrow_forwardWith reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra?

- Which ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.

What one of the options below is the most likely reason? He will have a diet high in iron. He is likely to be suffering from anaemia. He lives at high altitude. He has recently recovered from an accident where he lost a lot of blood. He has a very large body size.arrow_forward
