a. True
b. False
Natural gas forms from the remains of buried plants and animals. This statement is True.
Natural gas is primarily formed from the remains of buried plants and animals that existed millions of years ago.
The process starts with the accumulation of organic material, such as dead plants and microscopic organisms, in an anaerobic environment, like swamps or seabeds.
Over time, as more layers of sediment cover the organic matter, heat and pressure increase, transforming the organic material into hydrocarbons, including natural gas.
The process of converting these organic remains into natural gas is known as thermogenic gas formation.
While there are other sources of natural gas, such as methane produced by methanogenic bacteria, the majority of natural gas deposits are indeed derived from ancient organic material.

Answer:
true
Explanation:
Answer:
The pH scale has been drawn below.
Explanation:
pH sacle may be defined as the scale that determines the pH of acids and bases. 0 represent the neutral compounds. The compounds that pH less than 7 acts as acid whereas the compounds that have pH greater than 7 acts as base.
Here, water is neutral, Hydrochloric acid (HCl) is acidic and sodium hydroxide (NaOH) acts as base.
Water, hydrochloric acid, and sodium hydroxide can be placed on the pH scale as follows:
Water: Water is considered neutral and has a pH of 7. It falls in the middle of the pH scale.
Hydrochloric acid: Hydrochloric acid is a strong acid and is highly acidic. It has a pH below 7. The exact pH value of hydrochloric acid may vary depending on its concentration, but it typically falls within the range of 0 to 2.
Sodium hydroxide: Sodium hydroxide is a strong base and is highly alkaline. It has a pH above 7. Again, the specific pH value of sodium hydroxide can vary based on its concentration, but it typically falls within the range of 12 to 14.
So, on the pH scale, water would be placed at pH 7 (neutral), hydrochloric acid would be placed below pH 7 (acidic), and sodium hydroxide would be placed above pH 7 (alkaline).

The principle stating that the oldest rocks occur on the bottom of an undisturbed rock sequence is known as? The answer is superposition principle.
Transpiration is a water loss from a plant in the form of water vapor through small pores on the leaves. Plants take water from a soil through roots and release it into atmosphere through the leaves. This happens due to water gradient from the roots to the leaves. If for any reason transpiration stops, the water could not be released from the leaves, and consequently, the less water will be absorbed from the soil.
