Answer:
The answer is A. Draw branches for the domains: Bacteria, Archaea and Eukarya
Explanation:
Three Domains of Life:
Bacteria, Archaea and eukarya are the three principal branches or domains of the tree of life that explains the evolutionary relationship between all living organisms.
The first two domains, bacteria and archaea comprise the prokaryotic unicellular organisms. The third domain, eukarya includes all eukaryotic organisms.
All other organisms have evolved from these three principal domains.
Answer:
B. Some countries have many sources of beryllium, and some have no sources of beryllium.
Explanation:
Beryllium is a very important mineral that is present in many countries. All countries did not have beryllium deposits. Some countries have many sources and deposits of beryllium, and some have no sources of beryllium. There are many deposits of beryllium in different parts of United states of America. Those countries which have no beryllium deposits have cell phones because they purchase cell phones from international market by paying money which can be earned through selling of its goods.
The way that you will easily deduce which one it is is that you'll see the mouth first instead of the anus because of the different ways of development.
Answer:
The correct answer will be option-B
Explanation:
cDNA library or complementary library is the DNA library constructed from the mRNA which is isolated from the specific tissue.
The genomic library is constructed from the genome sequence of the organism by cutting the gene of interest or the whole genome with a restriction endonuclease and then inserting it into the vectors.
Since the genomic library includes the whole genome which is same in every cell and tissue whereas the cDNA library contains the coding genes expressed in the specific tissue only therefore, Option-B is the correct answer.
Answer:
By stopping the synthesis of proteins.
Explanation:
Streptomycin combines with the bacteria's ribosomes causing them to lose their function, the cells die and actually, this antibiotic destroys all the bacteria by stopping the synthesis of protein bacteria.
This antibiotic is blocking the development of bacteria. Streptomycin was used to fight tuberculosis and it's been made from the micro-organism <em>Actinobacterium Streptomyces griseus. </em>
