Thalamus and Prefontal cortex (PFC)
<span>Thalamus is known to be a
small region that is found at the center of the brain and function by relaying
signals to the eyes, mouth of the brain and function by relaying signals from
the eyes, skin, mouth and ears to the other part of the brain for processing.
However, prefontal cortex is the region of the brain that is involved in
planning complex cognitive behavior, decision making and personality
expression. Also, prefontal cortex are considered to be involved in thought
orchestration and support concrete rule learning.</span>
I believe the answer is (b.) <span>Cancer cells cause an autoimmune response which results in a build-up of cell matter.
This makes the autoimmune system perceive the cells as something dangerous, but since cancerous cells often not identified by the autoimmune cells properly, it often attacks the good cells (or its own tissues) instead which cause the life-threatening situation.</span>
Answer:
Explanation:
Consider the small sphere radius is x1.
therefore the large sphere radius is 3x1
As we know that volume of sphere=
So ,
Volume of the small sphere
=
also Volume of the large sphere
=
On solving the equation
volume of large sphere=27 * volume of small sphere
Hence
D is the right answer
But then again it is actually wrong... Either way D is the answer
