Answer:
Sella Turcica occurs on the sphenoid bone.
Explanation:
Sella Turcica is the saddle shaped bone of the skull and acts as cephlaometric landmark. The inner aspect of sella turcica consists of hypophysis or pituitary gland.
Sella Turcica is present in the sphenoid bone of the skull just behind the tuberculum sellae and chiasmatic groove. The shrink pituitary gland is indicated by the empty Sella Turcica.
Answer:
the do not break in the same way so false
Explanation:
Fracture and cleavage both describe how a mineral breaks. Fracture refers to rough or irregular surfaces along which the mineral breaks randomly. Cleavage refers to flat planes along which some minerals break.
Answer:
Explanation:
Alfred Hershey and Martha Chase showed that DNA is the genetic material by their blending experiment. Earlier it was believed that protein is the genetic material. As it is found in a larger amount in the cell.
Hershey and Chase infected the bacteria E coli with the T2 phage virus. In the bacteria, the viral DNA is replicated as the bacterial DNA. They prepare 2 culture media one contains radiolabeled phosphorus (32P) and another has radiolabeled (35 S)sulfur. Then he cultures the bacteria in separate culture medium and infected with many T2 phages.
After the infection, they isolated the infected cell and centrifuge the cells. When they tested separate supernatant of 2 culture mediums, they found the virus of radiolabeled phosphorus doesn't show any radioactivity. But the virus in the radiolabeled sulfur contains the radiolabeled.
The viruses have 2 biomolecules one is protein and the other is DNA/RNA. When they have centrifuged the cells which are the palette, the phosphorus is found there and it also degrades. But the sulfur which is present in the supernatant is present in the newly replicated viruses.
He also treated the virus with both the culture medium but newly infected cells show radiolabeled sulfur, not the phosphorus. Thus they concluded DNA is the genetic material.

An important safety reason that one can ask to the locals in regard to the water hazards in an area would be that it can prevent an injury or an accident. Hope this answer would then be of big help.
