Solve for us the question of the reasonableness of athiesm, where you get something (big bang)
from nothing — there must be a first cause of everything; explain implications of the anthropic principle and the wildly unprobablistic likelihood that our universe could even form in such a fashion as to be capable of sustaining life (which has, interestingly, your athiest heavy hitters (i.e. Dawkins, Schwartz, etc.) necessarily positing multiple universe theories to get around the near probablistic impossibility of all conditions be present at time of big bang for life to be possible without acknowledgement of a divine designing hand guiding the process); explain The probablistic impossibility of non-irreducibly complex basic
cells (life) coming together spontaneously (DNA,
cell membrane, etc), even the most basic, simple forms of life allowing for reproduction, metabolism, etc...

To help make ideas about energy more concrete, for example, the new unit will use a variety of analogies
from more familiar physical systems (e.g., combustion and charging a cellphone battery) to help students understand those same energy - releasing and energy - requiring chemical reactions and energy transfer when they occur in living organisms (e.g., cellular respiration, creating a charge across a
membrane in mitochondria and nerve
cells) where the reactions are more complex and difficult to observe.
Mitochondria, specialized organelles found in nearly every
cell of the body, use cellular respiration to generate one of the most important sources of chemical energy — adenosine triphosphate (ATP), a versatile nucleotide that powers everything
from cell division to
cell signaling to transportation of large molecules across the
cell membrane.
Davis suggests that the muscle
cells start extracting fat directly
from the blood and somehow transport this fat across the
