Accuracy describes how well a measuring instrument determines the variable it is measuring. How close the value is to real value. The level of accuracy of measuring tool determines the detail to which it can measure. In order to be accurate in their work scientists need first select a measuring instrument that allows an appropriate measure of accuracy and then to calibrate it. Calibrating an instrument involves measuring already known quantities to check how accurately it is. In the laboratory accuracy of a test is determined when possible comparing results from the test in question with results geenrated from an established reference method.

Which of the three things provide evidence that South America, Africa, Antarctica, and Australia were once together as one super
bazaltina [42]

Answer:

- Glacial deposits and scratches in the bedrock from an ice sheet match in distant regions

- Fossils of marsupials were originally the same across South America and Australia

- Cratons match across the edges of continents

Explanation:

South America, Africa, Antarctica, and Australia were all once part of one super-continent. This super-continent has been named Gondwanaland. As the geological processes got more intensive though and Gondwanaland separated into smaller land masses, continents, which we now know as the continents on the Southern Hemisphere. There are numerous clues that confirm that these continents were once connected. Some of the clues are the matching cratons on the edges of the continents, the glacial deposits and scratches in the bedrock are also matching, lot of fossilized flora and fauna from the same species have been found in several of these continents, the marsupials in South America and Australia  etc.

If one sample food contains 200 cal in another contains 300 cal, which statement applies?
Advocard [28]

<u>Answer</u>:

The food containing 200 calorie have less potential energy than the food containing 300 calorie

<u>Explanation</u>:

The potential energy content of a food material is its stored energy content which is in the form of chemical bonds. This energy can be measured through the combustion of food material inside a calorimeter. A calorimeter is an instrument which is used to measure the total calorie content of the food or other biological samples by measuring its heat content. A Calorie is unit of energy which is in form of heat.

The food material containing carbohydrates proteins and fats have energy in form of chemical bonds.  On the breaking of bond inside the body, energy is released as in the case of glucose breakdown also known as glycolysis.  

The energy released from glycolysis is used to synthesize high energy containing phosphoanhydride bonds. These ATP molecules are a further breakdown in the system to provide energy to the cell to perform various activities.
