BRAIN MAY GROW NEW CELLS DAILY. This zone was recently identified by other scientists as the home of the brain's stem cells, the source cells from which an organ is replenished. The new neurons migrated toward the cortex, matured and sent out axons to make connections with other brain cells, the Princeton biologists found.
Answer:
A.- 300kcal (315kcal) / B.- 100kcal (108kcal) - arround (30-35%)
Explanation:
In order to determine how many kilocalories have the meal, you have to multiply the macro-molecule grams as the following rule:
lipids * 9 / carbohydrates * 4 / proteins * 4
then
7g*9 + 36g*4 + 27g*4 = 63kcal + 144kcal + 108kcal (P) = 315kcal
