Answer:
Chemical bonds contain potential energy.
Explanation:
Chemical bonds always contain potential energy. The atoms of the bond want to move to a lower energy to become more stable.. The energy for breaking bonds only comes when stronger bonds are formed. This energy is used to tear apart the bonds holding the Hydrogen atoms together. The strength of the covalent bonds depend on the overlap between the valence orbitals of the bonded Atom.
Answer:
ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles →cell surface (exocytosis) (see Figure 17-13). Small transport vesicles bud off from the ER and fuse to form the cis-Golgi reticulum.
Answer:
Option c (
) is the correct alternative.
Explanation:
Given:
Common ancestor,
= 50 million years ago
Base differences,
= 92
Now,
The predicted mutation rate will be:
= 
= 
= 
or,
=
Thus the above solution is the right one.
