Ohibemating and Omigrating
Explanation:
Hibernating and migrating are repeated, cyclic behavior patterns related to external stimuli.
Because hibernation is a behavior of yearly cycle.
It is a state when a body of animal start processing slower as compared to before because there is fall in their body temperature.
Similarly migration occurs when climate of particular region becomes uncomfortable for some species , they migrate from there. Like birds, when they do not get water because of hotness or dryness in the weather, they all migrate to the place for enough water.
Hence, option 'C and 'E' are correct.
The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.
Recombinant DNA innovation gave an approach to researchers to create human insulin in the lab. The quality for human insulin is disengaged from human cells and embedded into plasmids. These plasmids are then brought into bacterial cells, which produce the insulin protein in view of the human code.
Recombinant DNA are currently used for all of the above (d).
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
