- "This energy is usually in the form of low-level thermal energy. It is only possible to extract work when there is a temperature difference, so low-level thermal velocity; this means that the force of friction and the applied force are equal in magnitude."
- "An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical."
Answer:
A.
Explanation:
The arctic soil is so cold that the ground beneath the tundra surface remains frozen all year. This permanently frozen ground is called permafrost. Each summer, when the sun warms the tundra surface, the top few inches of soil thaw. This melted part is called the active layer.
The correct answer for this question is A. Law of segregation.
All individuals have two alleles for a given trait. According to Mendel's Law of segregation, these alleles are passed down one each from both mother and father.
Explanations;
According to this law of segregation the allele pairs separate or segregate during the formation of gamete, during the process of meiosis, leaving each cell with a single allele for each trait, and randomly unite during fertilization. One pair of allele comes from the mother while the other pair comes from the father, and joins together to form a diploid cell. Therefore, organisms inherit two alleles for each trait one from each parent.
