Which is an accurate description of what occurs when a log burns? a. energy is created as the log burns b. the compounds that make up the log are converted into fire, heat, and energy. c. as the log burns, the nuclear binding energy of the molecules in the log is released. the nuclear binding energy is transformed into the light and heat of the fire. d. the molecules present in the log are transformed into molecules that contain less energy than the original molecules. the energy difference is the heat of the fire?

d. The molecules present in the log are transformed into molecules that contain less energy than the original molecules. The energy difference is the heat of the fire

Explanation:

When a log of wood burns, Oxygen must be present because it is a combustion reaction. A log of wood is composed of organic materials and the main organic material present is Carbon.

Due to the fact that Oxygen is present, Carbon reacts with Oxygen to form Carbon dioxide which contains lesser energy than Carbon.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
