Answer:
B
Explanation:
It’s B because the horse can feel the flies on its face.
The answer is 218.75
Upper limit for protein based on AMDR is 35% of the daily calorie needs. If the person calorie need is 2500 kcalories, the amount of calorie from protein would be: 2500kcal * 35%=875kcal.
Each gram of protein equal to 4kcal energy. The amount of protein in grams would be: 875kcal/ (4kcal/g)= 218.75g
Answer:
: A decrease in pH is too acidic compared to optimum pH for amylase activity.
Answer:
Method A is conduction and Method B is radiation.
Explanation:
Driving the situation in which the heat spreads through a "conductor". That is, although it is not in direct contact with the heat source, a body can modify its thermal energy if there is heat conduction by another body, or by another part of the same body. For example, while cooking something, if we leave a spoon against the pan, which is on the fire, after a while it will heat up too.
Heat is energy in transit. This energy is transported by means of electromagnetic waves in the infrared frequency. In the transmission of heat by radiation, this fact is more evident. All bodies emit radiation, just having a temperature. The only difference between light and heat is the frequency of radiation. Thermoses are a good example of thermal radiation. The walls of the thermos are double and silver. The double walls are separated by practically a vacuum, in such a way that the heat exchanges by conduction or convection are minimized, as they need a material medium to occur. The silver walls, on the other hand, minimize heat exchanges by radiation, thus making sure that the liquid inside the bottle does not lose or receive heat.
The thermodynamic barrier that must be overcome before products are formed in spontaneous reaction is activation energy.
The activation energy is the maximum amount of extra energy that is required by a reacting molecules to get converted into product. It is the minimum energy that is required or needed to activate or energize molecules or atoms.
It is needed in the reaction so that reactants can move together and overcome forces of repulsion and start bond breaking.
Reactant is the substance that takes part in and that undergoes change during a reaction.
