Answer:
Phase III.
Explanation:
Clinical research includes the different steps to test the particular drugs and its use for the medical treatment. Clinical research is divided into four main phases.
The phase III of the clinical research includes the double blinded study and its clinical trial on the patients. This phase determines the drug safety and efficacy. The therapeutic effect of the drug is tested directly in phase III of the clinical trial.
Thus, the answer is phase III.
Seymour Benzer used phage T4 mutants, Experimental
evidence that a gene is a linear sequence of nucleotide pairs. Some regions of
chromosomes have "hot spots" for mutations. Benzer's experimental
approach to fine structure mapping of the rII locus. Generated 1612 spontaneous point mutations
and several deletions in rII locus identified two complementation groups, rIIA
and rIIB. Mapped locations of deletions
relative to each other using recombination.
Mapped locations of point mutations relative to the deletions. Tested
for recombination between all point mutations within the same complementation
group.
The niche of grasshopper would include the plant species it eats.
Explanation:
The niche of an organism is different to that of a habitat. A niche includes the interaction between organisms and the food that they eat, whereas, a habitat is a place where organisms are provided with food, protection and shelter.
Habitat is a place of ecosystem that involves other environmental factors like- rain, sunlight, humidity etc. So, food type eaten by grasshopper would be the description of a niche and not a habitat.
10. A Cat because it's a mammal
Answer:
Endonerium
Explanation:
The endoneurium (also called endoneurial channel, endoneurial sheath, endoneurial tube, or Henle's sheath) is a layer of delicate connective tissue around the myelin sheath of each myelinated nerve fiber in the peripheral nervous system. Its component cells are called endoneurial cells.The endoneuria with their enclosed nerve fibers are bundled into groups called nerve fascicles, each fascicle within its own protective sheath called a perineurium. In sufficiently large nerves multiple fascicles, each with its blood supply and fatty tissue, may be bundled within yet another sheath, the epineurium.
