Robert hooke coined the term cell when studying thin slices of cork. these Dead
Plant Cells were the first cells observed because the thick cells.
<u>Answer</u>: Ionic bond
<u>Explanation</u>:
- An ionic bond is a type of a chemical bond formed by the complete transfer of electrons from one atom to another atom i.e one of the atoms loses its electrons and the other gains it. This results in the formation of 2 oppositely charged ions.
- In sodium chloride, sodium loses one electron from its outermost shell (valence shell) whereas chloride gains it. Due to this sodium gains, a net positive charge and chloride gain a net negative charge.
- So, due to the complete transfer of electrons that takes place from sodium to chloride, the compound generated (Sodium chloride) has an ionic bond.
A 3-base deletion in the AAUAAA sequence in the 3' untranslated region of an mRNA that eliminates the AAU, thereby preventing RNA polymerase from polyadenylation the mRNA would have the effect of; decreasing the number copies of the polyeptide that would be translated from this mRNA. A deletion is a mutation in which a part of a chromosome or a sequence of DNA is lost during DNA replication.
[Ar] 4s1 is the correct answer
The answer is , because one cell divides to form two identical cells.
