Select all that apply: Which of the following affect(s) the half-life of a radioactive substance?

Biology
1 answer:
frutty [35]3 years ago
8 0

Answer:

The correct answer is option A, the type of isotope

Explanation:

The half life of a radioactive substance is a constant value and thus it is not affected by the temperature, catalyst or mass of the substance.  Basically it is the time taken by a radioactive substance to reduce its mass by half of its actual value. Radioactive decay takes place only when the atomic nucleus becomes unstable and thus the isotope type is the only factor which affects the radioactive decay of any element.

Natalija [7]

Comparing the physical features of the three types of skeletons

<u>Endoskeleton :</u>                                        

Less Flexible than cartilage    

<u>Exoskeleton :</u>

very rigid and hard    

<u>Hydrostatic skeletons  </u> :  

Less rigid and very flexible

<h3>Physical difference of the types of skeletons </h3>

The endoskeleton is the internal skeleton present in vertebrates in the form of bones which enables the movement of animals while supporting the organs of the body to remain in position. they are less flexible when compared to cartilage. Exoskeletons are outer skeletons which protect organisms and also enables them to move freely. They are very rigid and hard.

Hence we can conclude that the comparison between the types of skeletons are as listed above.

Messenger RNA carries a(n) ___________ of the DNA’s instructions out of the nucleus to the ___________.
Nitella [24]


messenger RNA  (mRNA) carries a transcript (copy) of the DNA's instructions out of the nucleus  to the cytoplasm where it attaches to a ribosome.

transfer RNA (tRNA) begins to read (translate) the information on the attached mRNA and corresponding to this information, fetches the appropriate amino acids from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are linked into a chain or polymer forming the primary structure of the desired protein.
