What are some of the possible solutions for solving air pollution issues?
Answer:
Conserve energy - at home, at work, everywhere.
Look for the ENERGY STAR label when buying home or office equipment.
Carpool, use public transportation, bike, or walk whenever possible.
Follow gasoline refueling instructions for efficient vapor recovery, being careful not to spill fuel and always tightening your gas cap securely.
Consider purchasing portable gasoline containers labeled “spill-proof,” where available.
Keep car, boat, and other engines properly tuned.
Be sure your tires are properly inflated.
Use environmentally safe paints and cleaning products whenever possible.
Mulch or compost leaves and yard waste.
Consider using gas logs instead of wood.
Explanation:
Answer:
Make more earth-friendly ways to create energy using natrual resorces instead of fossil fuels releases greenhouse gases into the atmosphere and that causes the levles of Co2 and other gasses.
Example: Solar Energy, Wind Energy, Hydropower, etc.

the graph represents the decay curve of a radioactive isotope called strontium 90 what is the half life of this isotope
A. 8 years
B. 25
C. 50
D75
The half-life of strontium has been 25 years. Thus, option B is correct.
The half-life has been given as the amount of time required for an element to be reduced to half of its initial concentration. The half-life of the element has been given as:
[tex]A=\AA\;\dfrac{1}{2} ^\dfrac{t}{t1/2}[/tex]
Where, the initial concentration of sample, is given by [tex]\AA[/tex]
The final concentration of the sample is given by, A
The time of the reduction is given by t.
The half-life of the sample has been given by, t1/2
In the given graph, the initial concentration of the sample has been 100 grams. The time at which the concentration has been halved i.e. 50 grams is found after 25 years.
Thus, the half-life of strontium has been 25 years. Thus, option B is correct.
For more information about the half-life, refer to the link:

The steps in an investigation between two negatively charged objects are listed below.
Step 1: Rub a cloth on two uncharged balloons to make them negatively charged.
Step 2: Bring the two negatively charged balloons together.
Step 3: Observe the repulsion between the two objects.
Which statement is true?
An object changes its charge when placed near another charged object.
Bringing two positively charged objects close together would result in attraction.
The two balloons do not have to touch for repulsion to be observed.
Two negatively charged objects will attract each other when they touch.
Answer:
The two balloons do not have to touch for repulsion to be observed.
Explanation:
They don’t have to touch for them to repel. Hope this helps! ;)
The two balloons do not have to touch for repulsion to be observed. Repulsion is a force between two or more similar or like charges.
What is repulsion ?Charges that are distinct from one another one positive and one negative will attract one another, but charges that are identical either both positive or both negative will repel one another.
Repulsion is a force between two or more similar or like charges, whereas attraction is a force between two or more different or unlike charges or poles. Two magnets that are in close proximity to one another either attract or repel one another.
A molecule's electronic state in a repulsive state according to quantum mechanics is one for which the potential energy is not at a minimum. Since the potential energy steadily declines with the interatomic distance and the atoms repel one another, this indicates that the state is unstable and unbound.
Thus, option C is correct.

Please help! Can someone give me answers for 2.08 Graded Assignment: Boiling and Melting Points Exploration for 8th grade science
Here are the questions
(I couldn't make the graph)
1. Looking at the line plots on your graph, describe how boiling point and melting point vary with respect to atomic number.
2. Now look at the segment of the graph between the two data points marked with black squares. Describe how the boiling point and melting point plots behave between these points. Be as specific as possible.
3. On your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. Locate these elements on your periodic table. What term or description would you use to identify these elements with respect to the periodic table?
4. Now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. For each of these lines, describe any trends you see.
5. Locate the elements on your periodic table that you circled in green on your graph. What term or description would you use to identify these elements with respect to the periodic table?
6. After reviewing your answers to questions 2 and 4 above, would you define boiling point and melting point as a periodic table family trend (vertical groups), period trend (horizontal rows), or neither? Explain your answer.
7. Using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. Explain your answers.

Explain the symbiotic relationship of a coyote that eats a rabbit.
A coyote eating a rabbit is an example of....
I think this because..
A coyote eating a rabbit is an example of predation.
Predation is a form of relationship between two organisms in which one, the predator, kills and feeds on the other, the prey.
Usually, the predator is larger than the prey and can easily overpower it in order to feed.
Thus, a coyote eating a rabbit is an example of predation, granted that the coyote kills the rabbit just before eating it.

A praying mantis eats a bee.
Tell which type of relationship it is: mutualism, predation, parasitism, competition, or commensalism. Give details on why.
Try for 2 sentences:
I think a praying mantis eating a bee is an example of....
I think this because...
Answer:
I think a praying mantis eating a bee is an example of predation. I think this because the praying mantis stealthily hunts its preys, like the bee, in order to kill eat for food.
Explanation:
"Predation" refers to the killing of another living organism in order to prolong the life of the "predator" (hunter) and to end the reproductive life of the "prey" (the one being consumed). The praying mantis is popularly known for being a deadly predator because it feeds on several insects (as its prey), including the bees. They are said to also feed on wasps, moths, mice, frogs, rodents and even snakes.
It kills the bees in order to consume them so it can prolong its reproductive life. It then stops the reproductive life of the bees. Clearly, the type of relationship here is "predation."
I think a praying mantis eating a bee is an example of predation.
I think this is because the praying mantis which is a predator consume the prey which is the bee most times in a defensive manner.
Predation is a biological relationship in which a predator kills or consume it's prey.
It's occur majorly in canivorous animals that consume flesh or other animals.
The predators consume the prey as food and as a form of defensive means from been attacked by the prey.
In this relationship, energy is transfered from the prey which is the bee to the praying mantis.
Therefore, the relationship that occur between praying mantis and bee is predation.
