Answer:
A. Polyacrylamide gel electrophoresis (PAGE)
Explanation:
Protein fragments of different size can be separated by gel electrophoresis method. Different proteins are made up of different number of amino acids and so the chain length vary i.e. the size of different proteins may vary. Also different proteins may have different charges due to difference in the type of amino acids present in them.
Generally for separating the protein fragments according to their size polyacrylamide gel is used. Foe this proteins are first given the heat treatment and treated with SDS for unfolding the protein. SDS is a detergent that imparts negative charge to protein. During electrophoresis, under the electric field the separation would be only due to size but not charge as all the proteins are treated with SDS and thus have same negative charge. This method is called SDS-PAGE. Under the electric field, small protein fragments will move fast through the pores compared to large fragments leading to their separation.
If two proteins are of same size then to separate them wither agarose gel electrophoresis is used or isoelectric focusing.
Answer:
Clinical study report. In medicine, a clinical study report (CSR) on a clinical trial is a document, typically very long, providing much detail about the methods and results of a trial. A CSR is a scientific document addressing efficacy and safety, not a sales or marketing tool; its content is similar to that of a peer-reviewed academic paper.
Explanation:
Answer:
Factors that can affect the rate the rates of chemical reactions in the body are temperature, substrate concentration and presence and absence of enzymes.
Explanation:
Rate of a reaction may be defined as the speed of the reaction or the rate at which reactants are converted into products.
Increase or decrease in the range of temperature can affect the rate of a chemical reactions of the body. With increase in the temperature the rate of a reaction increases as the effective collision between the substrate increases and then decreases.
Enzymes are the biocatalyst that can increase the rate of a chemical reaction. The absence of the enzymes decreases the rate of a reaction.
The increase in the concentration of substrate increases the rate of a chemical reaction of the body.
Answer:
Graves´ disease is an autoinmmune disease that is caused when the immune system attacks the cells of the thyroid gland, which leads to an overproduction of the hormones secreted by the thyroid gland. This constant attack and destruction on the part of the immune cells causes the thyroid to increase in size, a condition that is commonly known as hyperthyroidism.
Hyperthyroidism can become a really serious issue because the excessive production of the hormones of the thyroid gland will increase the metabolic activity of all parts of the body and can, if left untreated, cause such serious conditions as blood clotting problems, type 1 diabetes, among others.
B) thyroid hormone
C) testosterone
D) parathyroid hormone
E) acetylcholine
Answer:
The correct answer will be option-E.
Explanation:
Acetylcholine belongs to a group of chemical messengers which also acts as neurotransmitters in the synaptic transmission of the signals.
The acetylcholine is present in the vesicles in the synaptic knob which when released at the neuromuscular junction cause the contraction of the skeletal muscle along with cardiac and smooth muscle.
The mechanism of action is different in different muscles as the neurotransmitter binds to the nicotinic receptors present on the motor endplate and opens ligand-gated sodium channels.
In smooth and cardiac muscle it binds to the muscarinic receptors and cause the release of calcium ions and potassium ions respectively and cause muscle contraction.
Thus, option-E is the correct answer.
Answer:
Glycogen.
Explanation:
Carbohydrates are the one of the most important bio molecules present in the living organisms. The carbohydrates are the polymers of the sugars that are linked through the glycosidic bonds.
The carbohydrate is stored in the form of starch in plants. The animals carbohydrates is stored in the form of glycogen. The sugars units are linked through the alpha glycosidic bonds with both the linear and branched chain structure.
Thus, the answer is glycogen.
b. transpiration
c. adhesion
d. cohesion
Answer: Adhesion
Explanation:
Adhesion can be defined as the property to water molecules by which it gets attached to other molecules is known as adhesion.
As water molecules is polar in nature they gets attracted towards polar molecules only. So, the one polar molecules(water) gets attached to another polar molecules by adhesion.
This property of water allows it to move from one place to another. The water from soil move to upper part of the plant by this property.
Hence, the correct answer is adhesion.
