Answer:
Sorry if this is long-
Explanation:
If water wasn't isn't recycled then all living things will eventually die out, everything on this earth that's alive needs water to live. removing water from the whole earth will kill all life and remove the most important greenhouse gas from the atmosphere.
If carbon dioxide wasn't recycled it will be removed from the atmosphere. and all the plants will die due to the lack of carbon dioxide. however, if you JUST remove carbon dioxide, plants and all animals will die due to the collapse of the food web, but there's a chance that certain species of bacteria will still live. you are also removing another green house gas from the atmosphere.
Without these green house gasses regulating the earths temperature. the earth may go into a deep freeze.
Nitrogen is an important component in amino acids. Organisms use amino acids to build proteins from dna. all living organisms use proteins for just about everything, from digestion to DNA replication. if we deplete our nitrogen, no organism on the earth can create proteins. which means, no organism can exist. Also the 4 bases of dna (adenine, guanine, cytosine, and thyamine) are nitrogen based. Without nitrogen you can't have DNA.
Scientists frequently use all of the following to support the theory that organisms change over time except.
Chocies:
1. Similarities in DNA
2. Similarities in early development
3. Similarities in body structure
4. Similarities in number of mates.
This is for science
Answer:
4
Explanation:
The gradual change in the species over the periods is called evolution. These changes help species to survive in nature and adapt to their surrounding.
The correct answer to the question is option D which is Similarities in a number of mates.
What is DNA?The molecule which stores all the genetic information of the body and regulates the formation of protein and hormones is called DNA.According to the question, the correct answer is option D because the number of mates can not help in the study of the evolution factor.
Hence, the correct answer is option D.

Explanation:
does temperature stay the same when heat energy increases?
Answer:
More energy is required to raise its temperature. Therefore, temperature does not stay the same when heat energy increases.
A student is pulling a large recycling bin. A teacher fills it with old papers to recycle. What property of the bin changes, and in what way? What does the student have to do to keep the bin moving at the same speed?
Answer:
the mass use his or her force to keep it at the same speed
Explanation:
List the three subatomic particles. Give the relative masses and charges of each.Identify the type of bond(s) present in each of the following substances:
NaCl
C2H6
MgO
Ag6
N2O4
F2
Fe5
CO2
Answer:
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
relative charge = -1
Relative mass = 1.1836
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.
Properties of cathode ray:
The ray is travel in straight line.
The cathode ray is independent of composition of cathode.
When electric field is applied cathode ray is deflected towards the positively charged plate.
Hence it was consist of negatively charged particles.
While neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Relative mass of proton= 1
Relative mass of neutron = 1
Relative mass of proton = +1
Relative charge of neutron = 0
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The umber of protons and electrons are always equal to make the atom electrically neutral.

Nora notices water droplets on the grass in the morning. It did not rain during the night. Which statement is true about this change of state?
1. Mass was added to the water particles, resulting in a deposition.
2. Energy was added to the water particles, resulting in evaporation.
3. Mass was removed from the water particles, resulting in sublimation.
4. Energy was removed from the water particles, resulting in condensation.
Answer:
4

What is a half-life of an isotope? please help
Answer:
Explanation:
Hello! Hope this helps!
One important measure of the rate at which a radioactive substance decays is called half-life, or t1/2. Half-life is the amount of time needed for one half of a given quantity of a substance to decay. Half-lives as short as 10–6 second and as long as 109 years are common.
