The presence of a protein in the
blood plasma
The differentiation among blood
groups results from the presence of a certain type of protein on the surface of
red blood cells in the body. This protein or antigen has two types which are
named Antigen A and Antigen B. A person whose blood group is A has the antigen
A on the surface his red blood cells, while a person whose blood group is B has
the antigen B on the surface of his red blood cells. However, a person who has
neither A nor B antigen has the blood group O, while a person who has both A and
B antigen has the blood group AB.
The answer is hydrolysis. This can be achieved through the use
of a strong acid or cellulolytic enzymes (from fungi) that are capable of converting
the cellulose to fermentable sugars. This pretreatment hydrolyzes the β-1,
4-glycosidic linkages of cellulose subunits.
Answer:
The neuron will not fire an action potential.
Explanation:
The missing magnitudes of the synaptic potentials when they reach the postsynaptic cell's axon hillock are:
A. excitatory +7
B. excitatory +10
C. inhibitory -3
D. excitatory +2
E. inhibitory -4
To fire the action potential, the summation of excitatory postsynaptic potentials (EPSP) and inhibitory postsynaptic potentials (IPSP) must reach the action potential threshold, which in this case is 15mV more positive than the resting potential.
The EPSP are: +7 +10 +2= +19
The IPSP are: -3 - 4= -7
EPSP + IPSP=
+19 -7 = +12 mV
The neuron will not fire an action potential since the integration of EPSP and IPSP is below 15mv.
The products for photosynthesis are sugar (C6H12O6) + oxygen (6O2)
