Answer:
D. predicting the age of the plant
Explanation:
stems don't exactly have those powers. but they do give support by holding the plant upright. they do give defensive properties. and they do increase the amount of sun exposure (like with sunflowers). but they don't predict anything.
C. Synthesis of enzymes for the cell
The double fortification process involves adding iodine and iron to salt. It is a method used to fight micronutrient deficiencies in developing countries. Iron and iodine are two of the most important micronutrients involved in cognitive function, maternal and infant survival and human productivity. This is a cost-effective method that ensures that the population receives these nutrients without having to change their eating habits.
Independent variable: Temperature
Levels: Room temperature
Freezing point 0C
Boiling point 100C
Dependent variable: breaking point of rubber bands measured in certain amount of temperature
Answer:
In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.
Explanation:
Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.
