Answer:
D. Population genetics
Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.
Explanation:
microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then
macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then
gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then
So it has to be D
Answer: Ice cores.
Explanation: Ice cores are commonly studied by scientists to find out what the climate was like decades and centuries ago.
Answer:
golgi tendon and muscle spindle
Answer: a. True
Explanation:
The main aim of the IRB is to safeguard the right of the human subjects used for the purpose of research conducted by the governmental authority. It also emphasizes over the protection of the researchers from illegal complaints. The risks to the human subjects can be minimized by using procedures which cause no harm to them and a detail consent of the research practice should be taken from these subjects by informing the purpose of research.
