Answer:

Ionizing radiation comes from these main sources:

Nuclear reactions in the Earth's sun and stars in space.

Radioactive decay in the body's tissues and in the soil.

Radioactive decay of unstable elements in rocks, especially rocks that contain radium and release radon gas.

Other examples of ionizing radiation include alpha, beta, and gamma rays from radioactive decay.

An electrician is carrying out some repairs in your house. He wants to replace a fuse by a piece of wire. Would you agree? Give
DerKrebs [107]

Answer: No

Explanation:

The electrician just cannot replace any piece of wire to fuse because the ceramic that is used in case of fuse has a wire attached in it.

This wire is of  low resistance so that when there is higher voltage the wire just cannot tolerate the high voltage and wire breaks down.

Any wire just cannot be replace by the fuse because the there are some calculations which has to be made.

The wire if used should be of low resistance and more properties then only it is eligible to be replaced by fuse.

Each atom of the element argon has 18 electrons. How many chemical bonds is one atom of argon likely to make with atoms of other
densk [106]
It won't. Argon is an element found in the Group 8A also called as the noble gases. They are called as such because they do not react with other elements because their electronic configuration is very stable. This is because they already obey the Octet rule, which has to do with eight electrons occupying around the element. So, it is very rare to have reaction involving any of the noble gases.

Kruka [31]

Answer:

The correct answer is option E) "The presence of one or more introns".

Explanation:

Introns are non coding sequences located within genetic sequences that are removed during RNA maturation by a process known as RNA splicing. A gene that has 2000 nucleotide pairs but is translated into a mRNA molecule with 1200 nucleotides most likely have one or more introns that in conjunction are of 800 nucleotides in size. Once the intros are removed from the mRNA molecule the coding sequence is ready to be translated into a protein.
