Answer:

t describes Linus Pauling's contribution to the understanding of DNA structure?

Having first discovered the spiral shape of proteins, Linus Pauling used x-ray technology to hypothesize that the DNA molecule consisted of two consistently spaced strands that formed a spiral shape.

Linus Pauling studied DNA base pairing.

Having originally studied proteins, Pauling proposed that DNA was a three-chained helix with a sugar-phosphate backbone at the center and bases sticking out from the backbone.

Linus Pauling conducted experiments to prove that DNA carried genetic information.

Answer

Cells use the hydrolysis of adenosine triphosphate, abbreviated as ATP, as a source of energy. Symbolically, this reaction can be written as

ATP(aq)+H_{2}0(l)- > ADP(aq)+H_{2} PO\frac{}{4} (aq)

where ADP represents adenosine diphosphate. For this reaction,  a. Calculate at b. If all the free energy from the metabolism of glucose

C_{6} H_{12}O_6(s)+6O_2(g)- > 6CO_2(g)+6H_2O(l)

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?

C_6H_1_2O_6(s)+O_2(g)- > 6CO_2(g)+6H_2O(l)

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?

Thanks!

Devise an experiment that tests the effects of changing salt concentrations on regeneration of brain cells in Alzheimer’s patien
Makovka662 [10]

Experiment that tests the effects of changing salt concentrations on regeneration of brain cells in Alzheimer’s patients.

Explanation:

Experiments are conducted on brain cells by first growing human embryonic stem cells in a Petri dish and then converting them to brain cells. later the Alzheimer’s disease was genetically engineered into those nerve cells through gene mutation.

When these cells are exposed to varying concentrations of salt solution, the cells with shrink or swell according to the concentration due to cellular osmosis.

The cells will undergo chemical changes due to this. The regeneration probabilities of nerve cells affected by Alzheimer’s disease can be studied by such experiments.
