The answer to this question is D have a nice day
ether patatos or bread is my best guess
I hope this helped
Answer:
0.05 mg/mL ( B )
Explanation:
Given data:
20 mg/ml starch
2% solution = 2g of solute is in 100g of solvent
<u>Determine the new concentration in mg/ml </u>
Dilution equation = C1V1 = C2V2
new concentration ; applying the dilution factor
dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every 100 mL
∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL
Answer:
C
Explanation:
a. refers to amount of energy passed upwards to each trophic level
b. only counts number of each organism
c. counts total mass of living tissue
d. i'm not familiar with but doesn't look right
When an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.
<h3>What is an allosteric enzyme?</h3>
Allosteric enzymes are catalysts that exhibit a site for binding that is distinct from the active site.
Allosteric enzymes are controlled by many effector compounds that can bind to different sites.
The active site of the enzyme is the molecular domain of this protein where reactants can bind during a chemical reaction.
The heterotropic effects occur when the ligands of allosteric modulators (effectors) are linked to the enzyme.
An allosteric modulator is a molecule that binds to the enzyme in a site different to the active site and this binding alters its tridimensional conformation, thereby activating it or deactivating it.
In conclusion, when an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.
