Answer:
Energy is passed between organisms through the food chain. The organism that obtains energy from sunlight is called the producer.
Explanation:
Process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.
The correct answer is Creaming.
Creaming is the technique of softening solid fat, like shortening or butter, into a smooth mass and then blending it with other ingredients. In milk biochemistry it involves a process in which fat droplets come together in larger clusters that rise and float to the top of the milk.
The Afrikaners are an example of a founder effect that occurs when population and the random decrease in genetic variation is an example of genetic drift.
Explanation:
When some individuals from a population move to form a new colony, this phenomenon is called founder effect as in case of Afrikaners. The small population or group of individuals forming a new colony may not exhibit the full genetic diversity of the population they were once the part.
The alleles would get expressed in different frequencies than it would have in original population.
There are chances that some alleles are lost or missing also. The new colony formed has small population so chances of genetic drift are very strong.
Genetic drift does not depend upon the benefit or harmful effect of the alleles as it occurs merely by chance sampling. The small population of Afrikaners felt the effect of genetic variation hence strong genetic drift is seen in them.
Solvents are dissolved in a solute to create a solution. Some examples are sugar solutions, where sugar is the solvent, water is the solute, and the solution is the sugar water that results, as long as the sugar is dissolved evenly in the water.
