Hello there @Neariah24

There is no exact number of how many stars there are in the galaxy. A star is born every 15 minutes in our galaxy.

Let me know if there is anything else I can help with!

I hope I helped

What do you think could be done to reduce levels of carbon dioxide in the atmosphere?
damaskus [11]
We cant really take away the carbon dioxide that is already present in the atmosphere unless with very advanced technologies but we can surely reduce the production level.

The production of carbon dioxide is mostly from the burning of fossil fuels and the gas produced by factories or vehicles.

As ourselves, we may not be able to stop the factories from producing gas and burning fuel but there are still something that we can do to help a bit. For example, turn off the electrical appliances when we're not using. This can save electricity thus to reduce the burning of fossil fuels. Or we can also take public transport instead of private vehicles to reduce the amout or carbon dioxide given out.

As the government, they should set up laws to control the gas produced by factories and vehicles, such as examining the gas content.

9. Which of the following is not a part of the peer review process or its result? A. Ensuring that work meets the standards of t
Tom [10]

Correct answer: C). Making sure that a piece of work is correct and includes bias

The peer review process can be defined as the process of exposing an author's research or ideas or results to be verified by the others who are expert in that field. Its main function is to encourage an author to meet the high standards of discipline in order to ensure that unacceptable results, interpretations or personal views are not published without the expert view.

Any scientific work should not contain any biasness as they may affect the validity of results. Hence, the scientific work does not have any bias.

Hence, the correct answer would be option C.

What is the difference between code, codon, and anticodon?
NeX [460]
The codon is a set of 3 nucleotides that can be read to convey a message in your DNA. It can be a code saying to "start" the process of protein synthesis, or "stop" it, or to encode for an amino acid - the building blocks of proteins. 
<span>The DNA is read, and proteins are made by DNA Polymerase (simple version here, it is more complicated, but this is the gist of it) travelling down the DNA. As it travels, it reads the nucleotides and builds a chain of amino acids, that corresponds to the information gleaned from the DNA. </span>
<span>So, the codon is only on one side of the DNA, and there are 2 sides. In order to be able to keep the DNA safe, and package it well (and loads of other reasons ) there is a complimentary strand. The nucleotides that make up DNA are A, T, C, and G. A links to T and C to G, and vice versa. </span>
So if your DNA strand's codons read "AAG AGG TCA"
Then the complimentary strand will read "TTC TCC AGT" the three codons on the complimentary strand ARE THE ANTICODONS of the codons on the strand being read (aka "expressed").
<span>So a codon and an anti codon are made of the same things, it just is a matter of which is being actively expressed. Now, this gets insanely complicated when you learn more about reading frames! Not only are there those codons, but if you shift and start reading the "code" either one nucleotide earlier or later, it completely changes the message.</span>
