If a person does not consume the minimal daily requirement of carbohydrates than the body will start to use the fat and proteins in the body so that it can produce energy. The carbohydrates are the primary energy source in the body, so the lack of them makes the body low on energy, and also it makes it harder to think and to remain active. If this process continues for a prolonged period of time, than it causes the building up of ketones in the blood, which results in ketosis.

I think the correct answer would be the first option. The best method to use in order to measure the distance of star would be to calculate the variations in the position of the star due to movement of Earth in its orbit. The doppler shift which is what is being described in the last three options does not calculate the distance rather it calculates the relative velocity. The method used in measuring the distance was introduced by Edwin Hubble where he found that relative velocity of a body in space is directly proportional to the distance of that body from Earth.
Answer:
The increase in temperature reflects an increase in the kinetic energy of the molecules, which favors the collision between the enzyme and substrate molecules. If the optimum pH changes, the conformation of the enzyme is altered and the substrate cannot enter its active site.
Explanation:
The relationship between pH and activity depends on the acid-base behavior of the enzyme and the substrate itself. Substrate and enzyme (active center) can contain acidic and basic functional groups, their degree of dissociation being dependent on pH, which will determine, among other aspects, the conformation of the protein, the binding capacity of the substrate to the active center of the enzyme and the transformation capacity of the substrate. The rate of an enzymatic reaction varies with increasing temperature. Such dependence reflects a double effect of temperature: positive at low values, due to the general increase that the speed of any chemical reaction experiences as temperature increases, and negative at high values, due to the thermal denaturation of the enzyme. That is, the speed of an enzymatic reaction increases as the temperature increases within a certain range, reaching a maximum value at the so-called optimal temperature. At higher values the activity decreases because the enzyme, like any other protein, undergoes denaturing processes and, therefore, inactivation.
