First blank: The mobility of their hosts same goes for the second one :)
These scientists all carried out experiments in accordance with the basic biological principle that life comes from pre-existing life. They investigated the theory of spontaneous generation and proved that life comes from life.
This also demonstrates that science is a way of knowing because they used what they saw in these experiments in other situations as well. They became able to do this only because they knew about this information and they got to know this information through science.
The answer is, d. consists of circular DNA molecule . The circular DNA is found in bacterias and archeas (which are prokaryotic organisms). The picture shows bacterial chromosome.
Answer:
Both are considered macromolecules. I'll explain below
Explanation:
Proteins are like a huge Lego construction. Each individual piece gets pieced together to make a larger "thing" - Death Star, House, etc. Each individual piece is a monomer, and the larger construction is the polymer. The monomers are Amino Acids and they get pieced together to form the polymer that is called a protein. The linkage that they use is an amide bond, and in biology it is usually called a peptide bond.
Carbohydrates can be singular monomers or polymer units. They are made of completely different compounds - usually aldehydes or ketones. And they link together through different chemical linkages (acetal or ketal linkages for polymers,hemiacetal or hemiketal linkages for monomers).
Both can be large, 3D strucutres - proteins are only functional as a large, 3D structure, while carbohydrates can be singular.
