When telescopes are looking at objects that are really far away, they are actually looking back in time.
True
False
Answer:
true
Explanation:
looking i the sky you can see stars that are billion years old
Time can be traversed via a telescope. Looking out into space is like looking back in time, according to NASA experts. Light needs time to traverse vast distances of space and come to Earth. Here the given statement is true.
The "deep" in Hubble Deep Field denotes the telescope's capacity to see some of these far-off, faint objects. It's like observing faraway space objects by going back in time. Even though light travels at an astounding rate, it still needs some time to cross the vastness of space.
Light travels slowly, so we don't see things as they are now, but as they were when they released the light that reached us from all over the galaxy.
Thus the given statement is true.

Nirates and phosphates are important chemicals to living things. Explain why these chemicals can also be pollutants.
Answer:
Nitrogen and phosphorus are essential elements for all living organisms. They are used in DNA and chemical processes in the body. Most nitrogen is found in the air and most phosphorus is bound up in rocks and sediments, making them unavailable to organisms. And they are pollutants cuz nitrogen and phosphorus support the growth of algae and aquatic plants, which provide food and habitat for fish, shellfish, and smaller organisms that live in water. But when too much nitrogen and phosphorus enter the environment - usually from a wide range of human activities - the air and water can become polluted
Explanation:
if my answer help, I hope you get better <3
Explanation:
When nitrate and phosphate ions concentrations in shallow waterbodies are in excess, there is overgrowth of water plants leading to the formation of algal bloom. This causes a high consumption of dissolved oxygen in the water. ... The dead plants and animals decay creating deterioration of water quality.

In Kevin’s favorite comic book, the superhero has special powers. In one adventure, the superhero must stop an evil villain who threatens to destroy the city with a powerful energy blast.
As he confronts the villain, he makes the following claims:
1: “I can create an energy force field to save the city.”
2: “I can destroy the energy before it destroys the city.”
3: “I can convert all the energy before it can do any harm to the city.”
4: “I can absorb all the energy and make it go away.”
If the superhero must obey the law of conservation of energy, which of the above can he actually do?
a. 1
b. 2
c. 3
d. 4
Answer:
3
Explanation:
The law of conservation of energy states that energy cannot just be created, so answer one is out. Energy also cannot be simply destroyed, so answer to is out as well. From here it gets tricky, since both answers make some sense under these rules. However, absorbed is bassically the same as destroying it leaving only answer three. Answer three does obey these laws, as energy can be converted.
Why have ice ages come and gone?
Answer:
"When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends."
Explanation:
Answer:
As temperatures decrease, less sunlight reaches the water. This causes the ice to freeze, when this happens in mass it causes an ice age. Later, temperatures rise and the ice melts.
Explanation:
Temperatures plummet as less sunlight reaches northern latitudes, and more water freezes into ice, triggering an ice age. Temperatures rise, ice sheets melt, and the ice age ends as more sunshine reaches northern latitudes.
The temperature of a plastic cup is 70ºF. It is filled with water that is 40ºF. Which of the following describes how thermal energy is transferred?
a. Thermal energy is transferred from the cup to the water until they are both at 45ºF.
b. Thermal energy is transferred from the cup to the water until the cup is at 60ºF and the water is at 50ºF.
c. Thermal energy is transferred from the water to the cup until they are both at 45ºF.
d. No thermal energy is transferred between the cup and the water, so the cup will stay at 70ºF and the water will stay at 40ºF.

I have no idea what this is about, I keep reading it over and other again, but I still don't understand! Help?
Answer:
A
Explanation:
So, here's a slightly simpler example:
If i had a jar, and i added sand, then rocks on top of the sand, and finally dirt on top of everything, what would the layers of the jar look like? (Assuming that i hadn't shaken the jar)
Well, the answer would be: The bottom of the jar would be a sand, the middle would be rocks, and on top would be dirt.
This question is pretty much the same question, just with fancier words and 4 things instead of 3
If the stars come first, then you find them at the very bottom of the jar. if the squares come second, then they are above the stars, but below the triangles, which come third. The circles come last, so you find them last. Thus the order is: stars, squares, triangles, and circles, from bottom to top, so it's A
Note: the jar represents the earth, and it too, may be shaken up in some places. This means that sometimes, if two organisms lived very close together in time (like the star and the square), and some event happened, you may occasionally see the square below the star. However, this question says that they weren't disturbed.
