what will happen if phase changes didn't exist?
Answer:
Matter can exist in one of several different states, including a gas, liquid, or solid state. The amount of energy in molecules of matter determines the state of matter.
A gas is a state of matter in which atoms or molecules have enough energy to move freely. The molecules come into contact with one another only when they randomly collide.
A liquid is a state of matter in which atoms or molecules are constantly in contact but have enough energy to keep changing positions relative to one another.
A solid is a state of matter in which atoms or molecules do not have enough energy to move. They are constantly in contact and in fixed positions relative to one another.

The concept of evolution by way of natural selection is a central tenet in biology that has been tested in numerous ways by many scientists. Evolution by way of natural selection is most likely which type of concept?
A. an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation
B. a likelihood based on the chance that a particular event will or will not occur during an experiment
C. a testable explanation or answer to a scientific question based on prior knowledge or research
D. a statement of fact that is accepted as true because it has always been observed to be true through observations and experimentation
Answer:
I know I am too late to help you, but I couldn't find an answer when looking for this question. I got it right and it is A. an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation.
Explanation:
Evolution by way of natural selection is most likely an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation. The correct option is A.
What is natural selection?Natural selection is the process through which organisms that are more adapted to their environment tend to survive and reproduce more than those that are not. Tree frogs, for example, are occasionally eaten by snakes and birds.
Evolution is a process in which living things or other evolve or change over time. Natural selection is also a reason for evolution, which takes a large amount of time.
Therefore, the correct option is A. an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation

The microscopic filtering units found in the kidneys that are responsible for urine formation are called
Answer:
nephrons
Explanation:
there are about one million nephrons in one kidney which are responsible for urine formation
The microscopic filtering units found in the kidneys that are responsible for urine formation are called nephrons, so here the correct option is option a.
Throughout the nephron, various processes such as filtration, reabsorption, and secretion occur to produce urine. Filtration occurs at the glomerulus, where water and small solutes are forced out of the blood into the Bowman's capsule. Reabsorption involves the selective reabsorption of water, ions, and nutrients from the filtrate back into the bloodstream. Secretion involves the active transport of waste products, excess ions, and toxins from the bloodstream into the filtrate. So here, the correct option is option a.

Why are common cold viruses difficult to cure?(1 point)
A copy of the DNA is made from the viral RNA.
The virus leads to other viral infections such as the flu and HIV.
The viral genome mutates very quickly.
Vaccines prevent the development of a cure.
Answer:
You are very correct the answer is c
Correct option is ''The viral genome mutates very quickly.''
Viruses can't reproduce on their own as bacteria do, instead, they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses. Antibiotics and medications treat bacterial infections. These antibiotics cannot treat or cure a common cold as colds aren't caused by bacteria.
Common cold viruses are difficult to cure as the viral genome mutates very quickly.
