Answer:
La historia de la química abarca un periodo de tiempo muy amplio, que va desde la prehistoria hasta el presente, y está ligada al desarrollo cultural de la humanidad y su conocimiento de la naturaleza. Las civilizaciones antiguas ya usaban tecnologías que demostraban su conocimiento de las transformaciones de la materia, y algunas servirían de base a los primeros estudios de la química. Entre ellas se cuentan la extracción de los metales de sus menas, la elaboración de aleaciones como el bronce, la fabricación de cerámica, esmaltes y vidrio, las fermentaciones de la cerveza y del vino, la extracción de sustancias de las plantas para usarlas como medicinas o perfumes y la transformación de las grasas en jabón.
Sometimes, the dark spots on the marshmallow can fall off of the marshmallow. This means that, the system does not need to include the pieces that fell when determining the mass before and after.
The venom of a poison dart frog has the special ability of being quiet permeable through the skin. A dart frog's poison can travel up the nerves, into the brain leading from tingling to pain, to paralysis, to coma, and then death. Its agonising.
No they can... But if you talk to your plants it helps they stay healthy because of the oxygen you are giving them.
Answer:
Explanation:
Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.
Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.
6CO2 + 6H20 --------> C6H12O6 + 6O2
Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.
C6H12O6 + 6O2 ------> 6C02 + 6H2O
One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.
