Answer: The correct answer is Option c.
Explanation:
Ions are formed when an atom looses or gains electrons.
If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form ions.
If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form ions.
Hence, the correct answer is Option c.
A ________ ion is created when an electron is removed.
a. stable
b. neutral
c. positive
d. negative
A cation or positive ion is created when an electron is removed. The answer is letter C.
A mixture can be separated into pure substances with the utilization of several techniques of physical methods like simple distillation, centrifugation, sedimentation, etc.
Simple distillation may be defined as a type of separation technique that involves the separation of solvent from a solution. This technique is utilized for purifying the liquids that comprise either nonvolatile impurities such as sand, salt, and other very small amounts of particles.
Apart from simple distillation, evaporation is also used to eliminate water or any liquid substance from a mixture. It makes the solution or mixture dry with the absolute absence of water.
The Centrifugation technique is used to separate the particles on the basis of their size, shape, density, viscosity, and rotor speed.
Therefore, with the utilization of separation techniques, one can easily separate a mixture into pure substances.

b. disease limits
c. carrying capacity
d. mutation rate
Answer;
Mutation rate
-Mutation rate is not a difference between a population showing exponential growth and a population showing logistic growth.
Explanation;
-When the resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve and when the resources are limited, populations exhibit logistic growth.
-The carrying capacity is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. It affects the size of population and thus has an effect on both exponential and logistic growth.
-Food limits and disease limits are also other factors that may determine the population size in a biological ecosystem.
require the United States to
(1) become involved in future international
conflicts
(2) pay for war damages
(3) adopt a policy of military alliances
(4) keep troops permanently in Europe
The Treaty of Versailles would require the United States to become involved in future international conflicts.
Therefore we can conclude that Germans oppose America involvement in future international conflicts.
Thus option 1. is the correct answer.
