Diamond will scratch quartz. True or False

Answers

Answer 1

Answer: false
hope this helps

Answer 2

Answer:

Answer:true, diamonds will scratch quartz.

Explanation: diamonds have a more compact composition. That is what makes them so hard. Quartz composition is not that compact, so diamond can scratch it.

A temperature reading of zero on the Celsius scale is equal to absolute zero. True or False? If False explain why ??

( Subject: Science )

^0^

Answers

No, that's false. 'Zero' on the Celsius scale
is 273 on the absolute scale.

False.

Absolute zero is actually 0 Kelvin.

Absolute zero is = -273°C, and not 0°C.

0 k = -273°C

A 0.426 kilogram football is kicked by a punter. If the applied force to the call is 62 Newton’s what is the acceleration of the ball.

Answers

Answer: The acceleration is 145.54 m/s^2

Explanation: The second Newton's law says that:

F = m*a

This says that the Force applied on an object is equal to the mass of the object times the acceleration of the object.

We know that the mass of the ball is 0.426kg and the force is 62N, so we have

62N = 0.426kg*a

a=62N/0.426kg= 145.54 m/s^2

62/.426=a

154.54= acceleration

What happens to carbohydrates during cellular respiration?

Answers

The microorganisms trap the energy in the sunlight by the process called as photosynthesis.Carbohydrates is mainly glucose, but other types of microorganisms are not able to follow this process. Therefore these organisms must rely upon prformed carbohydrates in the environment so that it obtains energy for its metabolic processes.

Final answer:

Carbohydrates, in particular, glucose, are broken down during cellular respiration to produce ATP, carbon dioxide, and water. This process consists of three stages: glycolysis, the citric acid cycle, and electron transport phosphorylation.

Explanation:

During the process of cellular respiration, carbohydrates—specifically glucose, which is a simple sugar—are broken down to produce energy in the form of ATP (adenosine triphosphate). This is a vital process carried out by all living organisms.

This complex process happens in three distinct stages: glycolysis, the citric acid cycle also referred to as the Krebs cycle, and electron transport phosphorylation also known as oxidative phosphorylation.

First, during glycolysis, one molecule of glucose gets broken down into two molecules of pyruvic acid and there is a net output of two ATP molecules. Next, the two molecules of pyruvic acid go through the citric acid cycle where they are oxidized to form carbon dioxide. Finally, during the electron transport chain, electrons are transferred through a series of proteins leading to the creation of water and producing a large amount of ATP.

Overall, the byproducts of this process are carbon dioxide and water, which are released as waste products.
