Correct Answer:
Option B. The creation is a solution
Since, the powered substance is fully dissolved in the water the resulting mixture will be a solution. As we are dissolving the powered substance in water, water will be our solvent and the powdered substance will be the solute. A suspension is the type of mixture in which solute particles are not completely dissolved in the solvent. Therefore, the correct answer to this question is the creation is a solution.
The three common elements seen in a majority of carbohydrates or sugars are Carbon, Hydrogen, and Oxygen.
Answer: B) there is a decrease in kinetic energy and the molecules get closer together.
Explanation: Kinetic energy is directly proportional to temperature, thus as temperature decreases, kinetic energy also decreases.
Gas is the state of matter in which particles are very loosely bound and hence can easily move past one another very easily and have highest kinetic energy.
Liquid is the state of matter in which particles are loosely bound and hence can move past one another easily and have high kinetic energy.
Solid is the state of matter in which particles are tightly bound and hence can not move easily and have low kinetic energy.
Thus on moving from gaseous to solid state, the kinetic energy decreases and the molecules get closer together.
Answer:
D) Frequency results from environmental stresses, not dominance.
Explanation:
The allele frequency refers to the amount of frequency of a particular allele in a small population whereas the dominance and recessive are the measure of the effects of the allele on the population which decides the trait of an organism.
The frequency and dominance cannot be correlated with each other as the frequency of the allele in a population is the result of the environmental stress which are random and by chances, whereas the effect of dominance is not random but is the result of the favoured trait for survival.
Thus, Option-D is correct.
