Answer:
To show effectiveness.
Explanation:
The logic of this procedure is to show the effectiveness of Anticholinesterase. Anticholinesterases are the drugs that prevent destruction of the neurotransmitter acetylcholine by the action of acetylcholinesterase enzyme within the nervous system. Anticholinesterases are very important drug due to their effectiveness that decrease breakdown of acetylcholine which is an important messenger of the nervous system so this procedure is very important to the effectiveness of Anticholinesterase drug.

If two air masses have the same relative humidity of 60 %, which one contains more water vapor?
a. The one with the higher temperature
b. Both would have the same amount
c. The one with higher relative humidity
d. The one with the lower temperature
b. Both would have the same amount
Option b. Both contain a similar amount.
Given that,
The two masses should have a similar relative humidity of 60%.We need to find out which have more water vapor.Based on the above information, we can say that since both two masses contain the same humidity i.e. 60% so it means that they have the same amount.
Therefore the option b is correct.

Answer:
chemical bond
Explanation:
A jar contains several different types of atoms. The proportions of these atoms can be changed slightly without changing any substance in the jar. This jar contains
Answer:
a mixture
Explanation: A mixture consists of different atoms that are not chemically bonded. It is of two types of the heterogeneous mixture and homogeneous mixture. The chemical substances can be differentiated visually in the heterogeneous mixture.
In a mixture, the proportion of atoms can be slightly changed without changing or modifying any substance. This is because the individual substances in mixture keep their properties when mixed together. Further, mixtures have variable compositions and substances. these mixtures can be are separated using physical methods.

radium in an element found in group 2 and period 7. in a normal radium atom, how many energy levels contain at least one atom?
A. 1 B.6 C.7 D.8
Answer:
the answer is d
Explanation:
In a normal radium atom, there are 7 energy levels.
The periodic table is arranged in groups and periods. The elements in a group have the same number of valence electrons while the elements in the same period have the same number of energy levels.
Radium is an element in period 7. The fact that it is in period 7 implies that it has 7 shells or energy levels. Hence, in a normal radium atom, there are 7 energy levels, each containing electrons.

Answer:
Low Pressure System
Explanation:
Low Pressure System is a region where the atmospheric pressure is lower than that of surrounding locations.
Low pressure because that sucks the surrounding air in creating a "mushroom cloud" of air and water vapour. This then cools and condenses creating clouds and rain.
