Explanation:
With magnets, there are simple explaination for it to move away or stick together by finding it's poles.
When 2 north poles or 2 south poles are next to each other, it will move away from the other
When 1 north pole and 1 south pole are next to each other, it will stick together.
Hope this help :3
Answer: is the opening of the Helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double Helix uncoil at a specific location called the origin
Explanation:
Photosynthesis Takes part in that.
Answer:
The pH of the soil, which is a measure of the acidity of the soil, governs to a large extent what is suited to and will grow well on a particular soil. Thus, agricultural crops, many of which go on to become our food, require soils in a particular pH range in order to produce their best yields. Both garden and wild flowers have a pH range in which they grow best. Similarly most organisms that live in the soil will operate in soils in a pH range that suits them. For example, one of the most common species of earthworms,has a strong preference for soils with a pH above 5.5 to just over 7.0. Other species of earthworm such as Allolobophora longa can tolerate pHs less than 5.5 but only down to about 4.5. Below pH 4.5 in Western Europe at least, there are usually few earthworms in the soil. pH also has an important effect on the availability of plant nutrients. Several nutrients become less available at the lower end of the pH range, i.e. below pH 5.5 and the availability of a few tails off significantly at pHs above 7.5. It is important that those who use the soil for purposes that depend on soil nutrients should be aware of the best pH range for key nutrients.

Answer:
Alternative energy is best defined as the use of energy sources other than traditional fossil fuels, which are considered environmentally harmful and are in short supply. Fossil fuels consist of natural gas, coal, and oil. Currently, fossil fuels are the most used energy source to heat our homes and power our cars.
