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
Some people really don't care about the environment. They always do ,what they want to do without even thinking about its consequences on the environment. They throw Cigrattes in the soil, Drop alcohol in soil .These activities makes the soil toxic and the crops that are grown in contaminated soil directly affects the human health.7) Acid rain
It is major reason for the contamination of soil. Some people thought that, It is the natural cause of soil pollution but that's not the reality. Humans are the one's who are responsible for acid rain. Contamination of these acids makes the soil very toxic that it kills the plants on the spot.Answer:
See below.
Explanation:
1) Plastic / Glass:
● Non biodegradable substances & takes a long time to decompose.

2. A cell with 100 chromosomes goes through meiosis. At the end, there are ____ daughter cells, each with ______ chromosomes.
During the process of meiosis, a cell with 100 chromosomes will produce 4 daughter cells, each with 50 chromosomes each the end.
What is Meiosis?Meiosis is a process in cell division and reproduction in which haploid cells are produced from diploid cells.
During meiosis, four daughter cells are produced from a single parent cell with each daughter cell having half the chromosome number of the patent cell.
Therefore, when a cell with 100 chromosomes goes through meiosis, at the end, there are will be 4 daughter cells, each with 50 chromosomes.

discuss the evidence supporting the benefits of stem cell research
The benefits of stem cell research are associated with the development of specialized cell lines.
What are stem cells?Stem cells are pluripotent cells that can be used to develop virtually any type of specialized cellular type.
These cells (stem cells) have the ability to self-renew and thus generate germinal layers present in an embryo.
Stem cells are used in research to investigate how certain gene expression patterns determine the formation of certain cellular types.

Examine the words.
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell
What idea can be described using all the words listed?
O the difference between the somatic and autonomic nervous systems
O the transfer of information from one neuron to another
O the difference between the central and peripheral nervous systems
O the flow of information within a neuron
Answer:
Answer is B
Explanation:
The idea that can be described using all the words listed is "the transfer of information from one neuron to another".
What is impulse?The term "impulse" refers to the electrical signal that travels down a neuron, while the term "presynaptic cell" refers to the neuron that sends the signal.
"Neurotransmitters" are chemicals released by presynaptic cells in order to send a signal to the next neuron.
The "receptors" on the surface of the postsynaptic cell are proteins that bind to neurotransmitters and receive the signal.
Finally, the "postsynaptic cell" is the neuron that receives the presynaptic cell's signal.
Thus, these terms describe the process of information transmission from one neuron to another across a synapse, the tiny gap between two neurons.

Which phase of cell division is shown?
O prophase
O anaphase
telophase
O metaphase
Answer: I don't have the picture you're looking at, but I can try to give you some clues to help you out.
Prophase is where the chromatids enter the cell and the chromosomes attach to the spindle fibers in the cell.
Metaphase: all of the chromosomes line up in the center of the cell (I use this trick I made up to remember this one: The chromosome will have Met the teacher's expectations when they line up in the center of the cell.)
Telophase: is where the sister chromatids go to opposite sides of the cell right before they split
Anaphase is when they finally split and are now classified as two different cells. One parent cell and one daughter cell.
I hope this helps you to solve your problem!

The coldest planet in the solar system is Neptune with an average temperature of -353 degrees Fahrenheit or -214 degrees Celsius.
Explanation:
Why venus is the hottest planet in the solar system?
The hottest planet in the solar system is Venus with an average temperature of 864 degrees Fahrenheit or 462 degrees Celsius. The coldest planet in the solar system is Neptune with an average temperature of -353 degrees Fahrenheit or -214 degrees Celsius.(In short venus is closed to the sun)
Why Neptune is the coldest planet in the solar system?
Neptune is the coldest planet within our Solar System because it is the furthest planet from the Sun. The Sun is the ultimate source of energy for the Solar System. The temperature of a planet is affected by its distance from the Sun. Radiation from the Sun is lost to its surroundings as it travels through space.

If the anterior pituitary began overproducing FSH due to a tumor, then the levels of inhibin would increase.
What is inhibin?The inhibin protein is a crucial factor involved in the generation of follicle-stimulating hormone (FSH) present in the body.
Inhibin protein is generated by specialized cells such as Sertoli cells (males) and granulosa cells (females).
In males, inhibin protein concentration in the blood is correlated to sperm (male gametes) count.

Explain why Neil Shubin thinks Tiktaalik says something about our own bodies? (in other words – why the Inner Fish title for the book?)
Answer:
Neil Shubin bases his argument that the anatomy of Tiktaalik is relevant to that of humans by discussing specific features of the anatomy of Tiktaalik that vary from typical fish anatomy and correspond to features of the human body. For example, he points out that Tiktaalik has a neck that is able to bend independently of the rest of the body, unlike fish, and like all terrestrial vertebrates, including humans. Therefore, the evolutionary history of humans can be traced to an organism similar to Tiktaalik, resulting in the concept of the "inner fish."

How do muscles work together to created movement
Answer
Basically they contract and then relax in different places back and forth.
Explanation:
When you move your arm for example, parts of that muscle are stretched while other parts become more relaxed to allow for the tension on certain parts. Basically when one part is stretched, the other part is relaxed, so they're always working together.
