Answer:
The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust. High tides are when water bulges upward, and low tides are when water drops down.
Answer:


Explanation:
Aluminium hydroxide (
) is a base and hydrobromic acid (HBr) is a strong acid.
Hence an acid-base reaction occurs between
and HBr
Balanced molecular equation:

Balanced total ionic equation:

Balanced net ionic equation:

(net ionic equation is written by removing common ions present in both side of total ionic equation)
True because a dehydration reaction is a conversion that involves the loss of water from the reacting molecule or ion. Dehydration reactions are common processes, the reverse of a hydration reaction. Common dehydrating agents used in organic synthesis include sulfuric acid and alumina. Often dehydration reactions are effected with heating.

the organisms would reduce in their population.
The sun is the source of the <span>energy that goes up
a food chain. This energy is converted to biomass by primary producers through photosynthesis.
Through interactions such as predation, this energy goes up the food chain from
the primary, secondary and tertiary consumers.
Therefore, if the sun stopped shining, there would be no energy for the food
chain.</span></span>
