Answer: Option E) the products have less potential energy than the reactants
Explanation:
Though the actual graph is not displayed, but, whenever reactants occupy a position higher than the product on the graph of reaction coordinate vs time taken, it means the reactants (AB+CD) have molecules with higher energy bonds than the products AC +BD
Thus, the reaction of AB + CD to yield AC+BD will occur spontaneously with the release of energy.
<span>Answer: Cellular differentiation is responsible for one daughter cell becoming a sieve tube whereas the other becomes a companion cell. Cell differentiation occurs as different genes are switched on and off.

Answer:
The given figure depicts the process of translation.
Translation is the process by which the mRNA is deciphered into the amino acid sequence of the polypeptide chain.
Ribosomes serve as the site of the translation.
The small and large subunits of the ribosome form the complex around the start codon of the mRNA.
It created three sites namely; A, P and E sites.
A site is a site where the charged tRNA enters the complex.
It then adds the amino acid specific to the codon sequence of the mRNA to the growing polypeptide chain at P site.
Uncharged tRNA then leave the complex through E site.
Natural selection means that the organisms better adapted to their environment, that is, they have developed the right characteristics/skills/response to the external ambient, have higher chance to survive, making the next generations genetically inherit such acquired surviving characteristics.
These generations will thus have a higher chance of survival, making these species being "naturally selected" as survivors, while those who haven't or are slower in this process, have a higher risk of elimination.
