Answer:
Genioglossus
Explanation:
The Genioglossus is paired extrinsic muscles of the tongue and is the primary muscle used for protruding the tongue
Answer:
Explanation:
Are you looking for sources of error? You'd need to evaluate the procedure itself. More info on this would be helpful!
Some common sources of error are ...
- Lack of temperature control (fixed by monitoring with thermometer, using a hot plate)
- Human traffic in room disrupting fine powders, etc. (decrease number of participants in room)
- Evaporation of substances over extended periods of time affecting yield
Already a few months prior after being buried, the body is already decaying. The body builds up with gas and has nowhere to go so the body becomes bloated thus attracting insects that break down the body and eat away as it progresses through the decaying process. The body goes through 5 stages of decay and thats autolysis and putrefaction. Autolysis, the body's enzymes begin to go into a meltdown and its sped up by extreme heat and slowed by extreme cold. Putrefaction is the bacteria that escapes from the body's intestinal tract and actually begins the process of literally melting the body down. Black purification is when the skin turns black and the corpse collapses and the gasses escapes. Fermentation is when the strong odors develop and there will be surface mold but the body has begun to dry out. Dry decay is when the cadaver has mostly dried out and the decaying process has slowed considerably. This when it starts taking longer but all the nasty stuff is over. So after twelve years and all that happens within the first years of being dead with or without a coffin at that. But in the end the body will be fully decomposed in 8-12 years and all that is left are the bones.
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.
