Answer: The receptor site is the location that a drug binds to, altering the function of a biomolecule.
Explanation:
The drug receptors site, are the sites where the sites where the drug molecules bind. Basically, a low number of receptors exists and the extent to which the molecules occupy their sites differ with the concentration of drug. The receptor site changes the conformation and function of the binding molecule of the drug.
Answer:
True
Explanation:
The lumen of a blood vessel helps determine blood pressure as blood flows through lumen and bp is measured in the lumen of artery
Ground Tissue, being it is the plant's stems, roots, and leaves.
Answer:
In the given case, the two scientists are working on a barley plant, independently determined a short plant mutation, and thus, created homozygous recessive lines of short plants. The measurements of the normal tall plants' height in comparison to the mutant short plants were performed carefully, which showed that the two mutant lines were having similar height.
In order to test whether these two mutant lines are carrying mutation of similar genes or of the distinct genes, complementation test is performed. In the test, it was found that the tall nature is dominant over the short. The complementation test takes place when the two strains of the organism exhibiting different homozygous recessive mutations generate the same phenotype, which is mutant and is also generating the wild type offspring when mated or crossed because of recessive mutation.
Complementation will take place only when there is a mutation in different genes. In the given case because of the wild type offspring, a complementation test will take place showing mutation of distinct genes. When the two strains are identical, there will be no generation of wild-type offspring because of which complementation test will not take place.
The answer is ‘arteries are less flexible’. This is why the older you get the more predisposed you
are to cardiovascular diseases such as high blood
pressure. However, regular
exercise may delay this development. The barometers in the blood vessels also
become less sensitive hence these vessels become less responsive to blood
pressure changes.
