Answers

Answer 1
Answer:

The most important part of an experiment would be; identifying and controlling variables.

In order to set up an experiment, you need to test the specimen(s) with and without a curtain variable. That is what makes an experiment a test.

Answer 2
Answer:

Answer:

identify and controlling variables

Explanation:

lack of awareness of control variables can lead to faulty result or what are called "confounding variables" additionally, noting control variables makes it easier to reproduce and experiment and establish the relationship between the independent and the dependent variable

The Celsius temperature scale is also something called the centigrade scale. Why is this?

Answers

There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin.

Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value.

Until the 1970s the Fahrenheit temperature scale was in general common use in English-speaking countries; the Celsius, or centigrade, scale was employed in most other countries and for scientific purposes worldwide. Since that time, however, most English-speaking countries have officially adopted the Celsius scale. The conversion formula for a temperature that is expressed on the Celsius (C) scale to its Fahrenheit (F) representation is: F = 9/5C + 32.

marinades that contain vinegar, wine, or yogurt are able to tenderize meat by breaking down collagen into smaller polypeptides because of their ________.

Answers

The answer is acidity.

Final answer:

Marinades containing vinegar, wine, or yogurt can tenderizemeat due to their acidity. The acidity breaks down collagen, a tough protein, making the meat more tender.

Explanation:

Marinades that contain vinegar, wine, or yogurt are able to tenderize meat by breaking down collagen into smaller polypeptides because of their acidity.

These ingredients are acidic in nature, and this acidity helps to break the bonds in protein strands, making them more tender.

Specifically, the acid in these marinades works to break down the collagen in the meat, a tough protein that can make meat difficult to chew.

By breaking down the collagen, the marinade makes the meat more tender and easier to eat.
