I think it's 420,000 kcal, because 10% of energy is lost as you move up each trophic level. To find what you started with you would multiply by 10 instead of dividing by 10. You have to multiply by 10 twice, because of the primary consumers and producers.
The cerebrum, which is composed of gray matter, is the largest part of the mature brain.
What is a cerebrum ?
the brain's biggest section. The cerebral hemispheres are the two hemispheres, or halves, that make up this structure. Speech, thought, emotions, reading, writing, and learning are all governed by regions of the cerebrum.
Several of your brain's "conscious" functions are controlled by your cerebrum. That means it is in charge of factors that demand thought.
Your cerebrum collaborates with other brain regions, particularly your cerebellum, to assist you with daily tasks. Picking up a pencil off of a table is one illustration of this.

Answer:
The correct answer is option (D) "His- strain grows on an his- plate".
Explanation:
The Ames test is a procedure that allows to detect if a given compound can cause mutations on a tested organism by growing strains of bacteria that require histidine (His-) to growth, since they are not able to produce its own histidine. In the Ames test, the bacteria is exposed to a given compound and is grown in a medium with small amount of histidine (his- plate). If the His- strain grows on a his- plate, it means that the bacteria has mutated to synthesize its own histidine and it is considered as a positive result on a the Ames test.
