Explanation:

Earth moves in an orbit around the sun. It is due to the gravitational force created due to the mass of the sun that pulls earth towards it. Gravitational force is responsible for the motion of Earth around the sun.

It is similar to the moon orbits earth due to Earth's gravity and as the earth orbits the sun due to the sun's gravity.

Hence, the correct option is (d) " Because the sun's mass creates a gravitational force that pulls Earth towards it".

What is an advantage and disadvantage of using 4.5-7.5 pH paper?
Butoxors [25]

Answer:

The correct answer would be:

Advantage: helps in finding the exact ph value with a narrower range.

Disadvantage: You don't know the exact ph value on a regular scale.

Explanation:

The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.

On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.

Relationship between photosynthesis and cellular respiration.

-Both involve in the production of energy

-Both involve the exchange of gases

-Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in the Chloroplast whereas respiration takes place in mitochondria.

-At critical condition both have an alternate pathway.

Extra: differences between photosynthesis and cellular respiration.

-Photosynthesis takes place in the chloroplast, whereas respiration takes place in mitochondria.

-Photosynthesis involves the production of carbohydrate and respiration involve breaking of carbohydrate.

-Photosynthesis occurs only during the presence of sunlight whereas respiration occurs all the time.

-In the photosynthesis process Oxygen is released whereas in respiration Oxygen is utilized.
