Sudan III is a bis(azo) chemical that has a 4-[(2 methylphenyl)diazenyl]phenyldiazenyl group replaced at position 1 of the 2-naphthol ring. a fat-soluble dye that can stain some protein-bound lipids in paraffin sections and is mostly used to show triglycerides in frozen sections.

It functions as a histology dye, a fluorochrome, and a carcinogen. It belongs to the class of azobenzenes, is a bis(azo) chemical, and is a naphthol. It is similar to a 2-naphthol in terms of function.

"It certainly does not mean, as many writers have assumed, that the lipid in question belongs to the carbohydrate-containing glycolipid (cerebroside) group.

Therefore, Little patches and blue- violet.

Dependent variable: Amount of plaque left in her teeth

Control group: Water

Constant: Same amount of time for product to have an effect

Independent variable is the variable that is subject to manipulation or change by the experimenter in order to effect a measurable response. The independent variable in this experiment is the DIFFERENT PRODUCTS OF TOOTHPASTE USED.

The dependent variable is the variable that is measured during the experiment. In this experiment, the dependent variable is the AMOUNT OF PLAQUE LEFT IN ALEX'S TEETH.

The control group in an experiment is the group that does not receive the treatment/independent variable. In this case, the usage of WATER is the control.

The constant is the variable kept the same for all the groups in the experiment. In the case, the Same amount of time for each product to have an effect on her teeth is the CONSTANT.

For the past 30 years, researchers have been experimenting with hooking a human brain up to a computer. They call it a brain-computer interface (or BCI), and they have been making progress over the past 10 years. In 1999, doctors were able to place a BCI in the brain of a man who had suffered a stroke. The BCI interpreted his "thoughts" so that he could use a mouse to move a cursor around on a computer screen to type out his words. This device allowed the man to "speak" with his family and friends even after the stroke had damaged most of his brain function. In 2004, doctors placed a BCI in the brain of a paralyzed man, allowing him to use a mouse to move a cursor. He could also type on a keyboard and play video games. He could even operate a robotic arm. This leap in technology will allow future scientists combine their knowledge of the human body with technology.A.
