Answer:
Since the origin of humans on this planet, they have been trying their best to make their lives easier on this planet. In doing so, human activities have some how heavily damaged the Earth. Many day to day activities of humans are dangerous for the Earth.
Some of the consequences of human activities on the Earth's fresh water are :
Extinction of many aquatic species:
The water consumed by humans comes from the fresh water oceans. As the population of humans is increasing enormously, the water from the oceans is being consumed at dangerous levels. This has caused many species of aquatic animals to become extinct or to be at a verge of extinction as they do not have a habitat to survive or reproduce.
Pollution:
Many heavy industries, house sewage, farmers dispose waste into the fresh water. Hence, killing aquatic animals and polluting the fresh water ecosystems.
B. Most of the breaking down and absorbing of food happens in the small intestine.
Electrical charged atom or group of atoms formed by lose or gain of electrons are ions
Explanation
Ions are formed when atom gain or lose electron.
They are two type of ion that is cation and anion.
Cation are positively charged ion and are formed when atom loses one or more electrons. for example Na+ formed when Na atom loses 1 electron.
Anion are negatively charged ion and are formed when atom gain one or more electrons. for example Cl- is formed when Cl atom gain 1 electron.
Answer:
5.088⋅10^10
Explanation:
First, we will put a decimal point at the end of number 50880000000.
In order to write number 50880000000. in scientific notation we need to move the decimal point from its current location (black dot) to the new position (red dot).
5.0880000000.
So, we need to move decimal point 10 places to the right.
This means that the power of 10 will be positive 10.
Now we have that the
Number part = 5.0880000000 ( which can be written as 5.088 ) and
Exponent part = 10
Answer:
All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs; they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores, herbivores, omnivores, or parasites
