<span>The metabolic processes in the body generate acids - for example lactic acid from anearobic respiration. The blood must be buffered against these acids to prevent them from raising the pH of the blood. Raising the pH of the blood would result in less biologically optimal conditions for tissues, cells and functionally critical enzymes in the bloodstream. For example, blood clotting may not work at very low (ie very acidic) pH.</span>
4) Fossil records support the lack of evidence of early photosynthetic plants.
Answer:
During this process the messenger RNA and the transfer RNA are manufactured
Explanation:
These RNAs are necessary to be able to comply with the formation of proteins, since they read the genetic code and after this they assemble the reading to make proteins of structure, function and support.
This is how cells when dividing or multiplying separate their genetic code by replicating.
Answer: See if cell phone cases are really a thing you need!
Explanation: Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!
External Respiration takes place in the Trachea. When oxygen and co2 "switch" its where they connect and making this external respiration!
I hope this helps you!
