(A. Cannot be true because human and monkeys are not that closely related
C. Cannot be true because it is not explicitly indicated by the DNA evidence provided by the excerpt

Answer: The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. Folded proteins are stabilized by thousands of non covalent bonds between amino acids.
Explanation:
Answer: Option D
Explanation:
The embryonic induction can be defined as the critical part in formation of the other tissues and organs because one cells affects the development of the other cells.
In vertebrates the notochord arises from the dorsal organiser, in amphibian the organizer is a region of vertebrate gastrulae which is when transplanted into the ventral region of the host embryo stimulates the formation of second embryonic axis and neural tube in embryo.
This generation of second notochord in the an example of influence of one group of cell on other.
Answer:
1. cerebellum
2. brainstem
3. cerebrum
4. cerebrum
5. brainstem
6. cerebrum
7. cerebellum
Explanation:
The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the<em> medulla oblongata</em>). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the <em>corpus callosum</em>.
