Soil pollutants are substances which contaminates the soil. Soil pollutants are very harmful substances ,they makes the soil toxic . The presence of these substances in higher concentration directly affects the ecosystem, earth etc.
Here are some major soil pollutants :-1) Industrial wastes
Industrial wastes are the common soil pollutants. The discharge of industrial waste in the soil makes it very toxic and directly affects the growth of plants (agriculture) .Industrial waste also affects the life of some organisms like earth worms which makes the soil more fertile.2) Pesticides
Pesticides are the substances which are generally used to kill the pestes. It includes Insecticides, herbicides and fungicides. The higher concentration of pesticides in cropfield directly affects the human health and responsible for soil pollution, water pollution etc.3) Hydrocarbons
Hydrocarbons are the substances which are composed of hydrogen and carbon. Only some hydrocarbons are responsible for soil pollution as they are very harmful for living organisms. for example the most harmful hydrocarbons is PAHs ( Polycyclic aromatic hydrocarbons) .PAHs in soil affects the growth of plants and it is indirectly responsible for the cancer in humans.4) Metals
Most of the people don't know that the higher concentration of some metals makes the soil very toxic . The concentration of these metals in soil directly kills the human beings and other living organisms.5) Non - biodegradable substances
Most people throw the trash in the soil even they know that soil can't degrade the non - biodegradable substances. When these non - biodegradable wastes eaten by street animals it directly affects the health of those animals and disturbs the ecosystem.6) Human activities

Which of the following is true statement?
Elastic objects can be stretched and return back to their original size.
Elastic objects never go back to their original shape.
Elastic objects will always break when stretched.
Elastic objects can never be stretched.
Answer:
Elastic objects never go back to their original shape.
Explanation:
When an elastic object is stretched beyond its limit of proportionality, the object does not return to its original length when the force is removed. In this instance, the relationship between force and extension changes from being linear, or directly proportional, to being non-linear.
Answer:
I don´t know if the other person is correct or not so don´t take my word for this but I think its A. Elastic objects can be stretched and return back to their original size.

Answer:
Einstein’s theory explained a famous observation that Newtonian gravity could not: a subtlety in the orbit of the planet Mercury. And his equations implied further slight deviations from Newtonian calculations. Over the last century, general relativity’s predictions have been repeatedly verified by modern precision measurements. To physicists today, general relativity and gravity are essentially synonyms.

As energy does
not cycle through
an ecosystem but
rather moves in
one direction,
what happens to
the energy that is
"lost"?
A. The energy is
released as heat.
B. The energy is
destroyed once an
organism is consumed.
C. The energy stays
with the original
organism.
Answer:
A
Explanation:
......................
The energy that is lost is released as heat in the ecosystem. So, the correct option is A.
What do you mean by Ecosystem?An ecosystem may be defined as the place or area where members of different species or communities live together and interact with one another for the purpose of food, shelter, and space.
The energy in the ecosystem moves in one direction which means from the bottom trophic level to the above. It never moves in the opposite direction until there will be damage to higher tropic level organisms. From there, it is released as heat.
Therefore, the correct option for this question is A.

Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell.
True or false?
Answer:
Explanation:
False sorry if it is wrong
Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.
What is Mitosis?A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.
A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.
Mitosis follows the same pattern. Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.
Therefore, Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.
