Because of this charge increase, the atoms of the alkaline earth metals are smaller and have higher first ionization energies than the alkali metals within the same period. The higher ionization energy makes the alkaline earth metals less reactive than the alkali metals; however, they are still very reactive elements

Answer:
The options to complete the question
A. Low
B. Good
C. High
D. Moderate
Our answer is surely C.
C. High
Explanation:
According to the nutrition facts panel;
A food nutrient is said be HIGH if the daily value(DV) obtained from a serving is of 20% high and above
A food nutrient is said be good if the daily value(DV) obtained from a serving is of 10-19% high and above
A food nutrient is said be low if the daily value(DV) obtained from a serving is of 5% or below 5% high and above
The nutrition facts panel sees good if the daily value(DV) obtained from a serving is of 10-19% high and above
The nutrition facts panel revealed the word moderate is yet to be assigned to a daily value unforese
Answer:
Right and left (X-axis)
Explanation:
This question is describing a microscope with a mechanical stage, which refers to the properties of the stage put in place to hold and move the slide. A mechanical stage consists of two knobs named X and Y knobs. They are so named after the direction in which they move the slide when used.
The X knob, which is the upper knob provides a clear view of the specimen by moving the slide in the X direction i.e. right and left. On the other hand, the Y knob moves the slide forward and backwards.
Answer:
-100
Explanation:
If the total water potential in the soil around a plant root were -50 kPa, water would move from the soil into the root if the water potential inside the root cells were -100 kPa.
The water potential of a substance represents the measure of potential energy in water molecules in a system as compared to that of pure water. It is also a measure of the tendency of water to move from one region to another.
<em>Usually, water will move from the region of high water potential to the region of low water potential. Hence, for water to move from the soil into the root, the root must have a lower water potential than the soil.</em>
The soil had -50 kPa water potential, hence the only option that is lower than -50 kPa is -100.
The correct answer is -100 kPa.
