The thalamus is located between the midbrain and the cerebral cortex. It filters sensory information and directs them to appropriate parts of cerebrum.
Hypothalamus is located beneath the thalamus. It is an integrating center for many important homeostatic functions.

Answer:
d. secondary endosymbiosis.
Explanation:
- When a living cell acquires another organism that eventually becomes a part of this cell, this process is known as primary endosymbiosis.
- When an organism that has already undergone primary endosymbiosis engulfs another eukaryotic organism then this process is known as secondary endosymbiosis.
- Secondary endosymbiosis has been known to occur in plastids because of which they are surrounded by two membranes. This bilayer is present because one of the layers is the original outer membrane of the organism and the other membrane is that of the organism that has been engulfed.
