Answer:
Alfred Russel Wallace was born in 1823 in Wales. He has been variously described as a naturalist, a geographer, and a social critic. He even chimed in on the debate over whether life could exist on Mars. His work on the theory of natural selection, however, is what he is best known for. During the second half of the nineteenth century, he became a public figure in England, known for his courageous views on scientific, social, and spiritualist subjects. His formulation of the theory of evolution by natural selection, which predated Charles Darwin's published contributions, is his most notable legacy, but it was only one of many contentious issues he studied and wrote about during his lifetime.
The answer is option D. We have no way of knowing the number of revolutions of the planets.
Genetically modified bacteria (recombinant bacteria) with the human gene for insulin is useful because after it’s being put in fermentation tank it starts to produce human insulin protein. The process of making recombinant bacteria includes DNA cloning.
A target gene, in this case, insulin gene, is inserted into a circular piece of DNA called a plasmid via restriction enzymes and DNA ligases. Recombinant DNA is then introduced into bacteria via a process called transformation. With the right conditions the bacteria that contains the human insulin gene, will start transcribing the gene and translating the mRNA to produce many molecules of human insulin protein.
One very common function of an antenna of an arthropod would be for sensory. It is used by these organisms mainly for touch. Also, other uses would be sensing the motion of air, heat, sound and as well as taste and smell.
