Please help me with cell bio Which of the following statements about the cellular and non-cellular components of blood is false? water is the most abundant component of plasma plasma does not contain red blood cells blood serum contains mostly album and globulins blood serum contains albumins, globulins and dolling factors True/False The phloem transports products of photosynthesis from the leaves to other parts of a plant The detergent SDS (sodium dodecyl sulfate) has no effect on a protein's structure In an ELISA assay antibodies against human albumin will react more strongly to chicken albumin than to gorilla albumin Eosin is a basophilic dye that stains nuclei The epithelium of the esophagus is a pseudostratified epithelium SDS-treated proteins have a uniform negative chargeExplanation / Answer
Que 11
Ans:
The following statement about the cellular and non cellular component of blood is false: Blood serum contains albumins, globulins and clotting factors.
Explanation:
- Serum is clear liquid that can be seperated from clotted blood.
- Blood serum is about 90% water with dissolved proteins, minerals, hormones and carbon dioxide.
- In blood, serum is the component that is neither a blood cell nor a clotting factor.
- Serum= Plasma - Clotting factors.
Que 12.
Ans:
The phloem transports products of photosynthesis from the leaves to the other parts of a plant: True.
Explanation:
- Plants have a transport system, in some ways similiar to an animal's blood circulatory system.
- Phloem tubes carry sugars ( sucrose is more likely than glucose ) and other foods such as amino acids produced as a result of photosynthesis.
Que 13.
Ans:
The detergent SDS (sodium dodecyl sulfate) has no effect on a proteins strcture: False.
Explanation:
- SDS completely disrupts protein-protein interactions and denatures almost all proteins resulting in a complete unfolding of proteins.
- When protein molecules are treated with SDS, the detergent disrupts the secondary, tertiary and quaternary strcture to produce to produce linear polypeptide chains coated with negatively charged SDS molecules.
