A very rare disease will cause damage to the ribosomes in cells. what would be the direct effect of this disease?
DochEvi [55]

Answer:

A rare disease that causes damage to the cell's ribosomes will have as a direct effect the inability to perform protein synthesis.

Explanation:

Ribosomes are cellular organelles formed by proteins and a type of RNA called ribosomal RNA, whose function is to translate the genetic code of the mRNA codon sequence and convert it into amino acids. This implies the first step for protein synthesis to occur.

<em><u>If a rare disease could structurally or functionally affect the ribosomes, the translation of mRNA into amino acids could not occur, so protein synthesis in the cell would not be possible</u></em>.

The consequences of the lack of protein synthesis involve severe consequences on the structure and function of a living organism.

Can someone please help me answer questions 16-20 please. Thank you!!
torisob [31]

Answer:

16) 6 electrons

17) 6 protons

18) 6 neutrons

19) 4 electrons

20) 6

Explanation:

There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.
