Answer:

for differentiation

Explanation:

By gram staining, we can determine about gram-positive and gram-negative bacteria. If bacteria are Gram-positive then for further catalase test perform. If bacteria give catalase-positive then that's mean this bacteria is Staphylococcus. If bacteria give catalase-negative result then that's mean this bacteria is streptococcus.

The bacteria that are catalase-positive for their further identification coagulase test perform if bacteria is coagulase-positive that's mean it is staphylococcus aureus and if it is coagulase-negative that's mean that maybe differentiation saprophyticus or other species.

Which of the following tags should be used to retrieve information from a
Viefleur [7K]

Answer:

<em>The correct option is A. Nucleotide sequence, human, hemoglobin</em>

Explanation:

If the segment of the DNA for the human gene is known then it will be very easy to find the gene on a database. The tags which should be used will be the nucleotide sequence, where the known sequence shall be mentioned.

Then we will choose the tag for the organism which is humans in this case. Then we will select the tag for the protein which is made by the nucleotide sequence, which is protein in this case. Hence, option A is the correct answer.

What factor does not contribute to "water stress" on the Earth?
kotegsom [21]

Precipitation differences are the factor that does not contribute to "water stress" on the Earth.

<u>Explanation:</u>

  • Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
  • Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
  • An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.

frosja888 [35]

Answer:

Gene therapy

Explanation:

Gene therapy can be defined as the methodologies used to modify/restore the expression of target genes and thus cure and treat genetic disorders. Gene therapy approaches consist of delivering specific nucleic acids (either RNA or DNA) in the cells of the individual to be treated. Some of the most important gene therapy approaches include the use of small interfering RNAs (siRNAs) in order to block target gene expression, adenovirus vectors to insert genes into host cells, the use of the CRISPR-Cas9 genome editing system to insert specific sequences by the mechanism of homologous recombination, etc.

24.) C - a change in DNA coding can lead to a change in the protein that is produced, which changes structure, and therefore, function. 
28.) C - recombinant DNA is artificial, and the other examples can occur naturally 
29.) B - if DNA enters and successfully is produced within a plant cell, but is not originally from the plant cell, then the cell has been transformed.
