The classic Hershey and Chase (1952) experiment that offered evidence in support of DNA being the genetic material in bacterioph
MArishka [77]

Answer:

The correct answer is- phosphorus and sulfur

Explanation:

Hershey and Chase used radioactive phosphorus and sulfur to label T2 bacteriophage. Then they infected E.coli with these bacteriophage labeled with radioactive phosphorus and sulfur.

After infection, they centrifuge the cell and found that radioactive phosphorus is present in the bottom and radioactive sulfur in supernatant . As sulfur is mostly the part of protein not  DNA and is found in supernatant  and phosphorus is mostly present in DNA not protein which was found in cell debris, therefore, it was proved that DNA is the genetic material.

IThese statements compare and contrast Ascomycota and Basidiomycota. I. Some species in both groups can cause plant diseases. II
amm1812

The correct answer is I and IV

In the Basidiomycetes, the spores are produced externally on the end of specialized club-shaped structure called basidia. Whereas, In ascomycetes, spores are produced internally, in the sac-like structure called an ascus.  Some members of ascomycetes cause plant diseases such as powdery mildew of grape (<em>Uncinula necator</em>), chestnut blight (<em>Cryphonectria parasitica</em>), and apple scab (<em>Venturia inequalis)</em>. Memers of basidiomyctes cause smut of corn (<em>Ustilago maydis</em>), brown root rot, and coffee rust.

How does the circulatory system interact with the digestive system ?
Alexandra [31]

The digestive system breaks down food molecules into their component parts, which are then absorbed by the circulatory system in the small intestine and circulated throughout the body. The digestive system diffuses nutrients into the capillaries and then through the circulatory system. The small intestine has folds called villi, and the villi contain tiny projections called microvilli. The microvilli absorb nutrients from digested food and transport it directly into the bloodstream where it can be used. Without the circulatory system, the body would not be able to absorb nutrients from the food we eat.

The circulatory system supplies the organs with blood and oxygen to keep them alive. Oxygen travels throughout the body including the digestive system. Like any organ, the digestive system requires more oxygen when metabolically active, for example after a meal. In addition, the digestive system plays a role in the acid-base balance in the body. Since H+ + HC03- exchanges with H20 and C02 within the intestine there is a production of carbon dioxide from the gut to the lungs.

The bloodstream carries nutrients that are broken by the digestive system from the food you eat. The circulatory system provides nutrients and oxygen to the organs of the digestive system.
