Acids have a ph of 6 and below whole bases have a ph of 8 and above. If a human has to much acid in their stomach they can take a pill that will lower it back to its normal ph level
Answer:
DNA is the genetic material of all the living organism except some viruses. The structure and the characteristics of the DNA was well explained by Watson and Crick.
DNA is a double stranded molecule in which nitrogenous bases are linked together. Watson and crick explained that DNA strand are antiparallel. The antiparallel nature of the strand means one DNA gas a polarity of 5' to 3' direction whereas the another strand of the DNA gas polarity of 3' to 5' direction. These two strands has opposite polarity and runs in anti parallel directions. Thus, the DNA strand known as antiparallel strands.
Answer:
The correct answer is both pumps use proteins to transport substances across the cell membrane.
Explanation:
Sodium potassium pump helps in the active transport or uphill transport of both sodium and potassium across the cell membrane against their concentration gradient.
Whereas Ca2+ATPase or calcium pump itself is a trans membrane or membrane spanning protein which helps in the transport of Ca2+ outside the cell to maintain electrochemical potential of Ca2+ ions.
Answer:
Cells are the basic units of structure and make up tissues.
Hope it helps :)
Dependent reaction is the factor that is observed and measured
