I mean, your cerebrum is a part of your brain so...
Sap flows when daytime temperatures rise above freezing (32 degrees Fahrenheit / 0 Celsius) and nighttime temperatures fall below freezing.
The rising temperature creates pressure in the tree generating the sap flow.
Alleles or genes m8. Could also go with traits maybe but that’s not as specific
1) Producing more offspring at a time
2)Reproducing more often
3)Reproducing earlier in life
Greenhouse effect - atmosphere traps additional heat (some light absorbed, some reflected. Reflected in form of infrared light. GE occurs when the atmosphere temporarily traps some of the infrared light that the ground emits, slowing its return to space.) Occurs only when the atmosphere contains gases that can absorb infrared light (greenhouse gases: H2O, CO2, methane (CH4).
