Carbohydrate consists as the name as of carbon and hydrogen and oxygen in the same ratio as water (hydra). Another name for carbohydrates would be saccharides... this is for an example glucose, ribose and so on... and we use fx glucose in cellular respriation.
A carbohydrate<span> is a biological </span>molecule<span> consisting of carbon, hydrogen, and oxygen </span>
Answer:
false
Explanation:
it is because sugar not needed in photosynthesis
Answer:
The correct answer is option D.
Explanation:
In the presence of SDS single band appeared, while in the absence of SDS two bands appeared. SDS or sodium dodecyl sulfate refers to an anionic detergent, which combines with amino acid side chains providing the protein a net negative charge. It dissociates the non-covalent bonds.
In SDS-PAGE, the separation of proteins takes place on the basis of their molecular weight. Options A and B are incorrect as only in the presence of SDS, the separation of protein subunits takes place. Option C is also incorrect as a protein containing distinct molecular weight cannot show single band.
Option D is correct as the presence of SDS supplements a bunch of negative charges to the protein, thus, charge is not the factor. Therefore, the proteins are distinguished on the basis of the molecular weight. Thus, identical molecular weight demonstrates a single band. In the non-presence of SDS, charge performs a function along with the molecular weight, therefore, two bands appear.
Answer: Remember that velocity includes the speed and direction of an object. Therefore, a change in velocity can be either a change in how fast something is moving or a change in the direction it is moving. occur all around you as objects speed up,slow down, or change direction.
Explanation:
The answer is: the amount of the saliva samples must stay consistent while the amount of starch must vary.
The amount of the saliva samples must stay consistent because amylase, present in the saliva, is the independent variable which affects the dependent variable - the amount of starch. So, amylase will do its job while remaining surface area of the starch will depend on the starting amount of the starch.
