Students have asked these similar questions

A 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.

With 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? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. 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-haemoglobin

The intermediate filaments as neurofilaments are present in the cytoplasm of nerve cell; they provide structural support and also help in regulating the axon diameter.

Answer 41

F.

Summary Introduction

To explain: Sperm cell contains a high density of intermediate filaments in their cytoplasm or not.

Introduction: Intermediate filaments are the components of cytoskeleton and found in the cytoplasm of almost all animals. These are also found in the nucleus of eukaryotic cell. It maintains the cell shape and rigidity. It also provides mechanical support to the cell but is not involved in the cell motility.

Expert Solution

Answer to Problem 1Q

Correct answer: This cell does not contain high density of intermediate filaments in their cytoplasm.

Explanation of Solution

Sperm cell never develops or strengthens large tensile forces, so there is no need of cytoplasmic intermediate filaments.

Answer to Problem 1Q

Correct answer: It does not have a high density of intermediate filaments in their cytoplasm.

Explanation of Solution

The rigid cell walls of the plant cell provide mechanical support to the plant rather than cytoplasmic intermediate filaments.
