Placebo responses greatly influence ordinary clinical outcomes, making placebo controls essential in randomized clinical trials (RCTs).
What are the placebome, or genetics, and the placebo effect?
Recent research in neurophysiology reveals the neurotransmitter networks that control placebo effects. It is possible to use genetic screening to identify placebo responders, which would boost the efficiency of RCTs and enhance therapeutic treatment. This is supported by evidence that genetic differences in these pathways can alter placebo effects. Additionally, the design of RCTs should take into account any potential interactions between the molecular pathways of the medicine and the placebo. The placebome, a study of the genetic influences on placebo response, is still in its infancy. Here, we evaluate data from placebo trials and RCTs to pinpoint putative genes in the placebome, look into data for interactions between placebo and drugs, and discuss implications for clinical care and RCTs.

Under the directional selection, the genotype might change and the genotypes is the one that represent larger individuals become more prevalent. It might change, the Genotype frequencies under directional selection that the Genotypes that represent larger individuals become more prevalent. The answer in this question is the genotypes is the one that represent larger individuals become more prevalent.
Answer:
The correct answer will be option-neural tube, hindbrain, metencephalon,
Explanation:
The development of the brain during the embryogenesis takes place by the formation of a neural tube or the predecessor of the central nervous system.
The neural tube arises from the ectoderm layer of the gastrula where the anterior portion of the neural tube forms the brain.
The neural tube development results in the formation of three sacs filled vesicles in which the fist vesicle forms the forebrain, second forms the midbrain and the third vesicle forms the hindbrain.
Later development process divides the hindbrain into two new portions called metencephalon and myelencephalon where the metencephalon forms the cerebellum portion of the brain.
Thus, the selected order is the correct order.
Answer:
Option-C
Explanation:
Apoptosis is a genetically controlled process taking place in the multicellular organisms which is marked with the self-destruction called or programmed cell death.
During apoptosis various physiological and morphological changes take place in the cell such as fragmentation of nuclear DNA, nucleus, shrinkage of cell and mRNA decay.
Since apoptotic cell undergoes cell death which is genetically controlled or programmed by the genes, therefore, apoptosis is known as the programmed cell death.
Thus, Option-C is the correct answer.
