O BO OO
you get 25% for each phenotype
Answer: A. Chemical signal
Explanation:
Chemical signal is the type of communication which coordinates actions between neighboring cells
.
This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma membrane and changes are brought about within the cell in response to this message.
Answer; All the above
A) an atom seeks to fill its outer shell of electrons
B) an atom seeks to balance its positive and negative charges
C) the reaction will result in paired electrons
Explanation;
-In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
-During a chemical reaction an atom may lose of gain electrons resulting positive and negative ions (ionic bond formation) or may result to the paired electrons (sharing of electrons).
