The model of magnetic attraction and magnetic repulsion are given below:
Repulsion: N <----> N or S <----> S
Attraction: N ---><--- S or S --><--- N
What is the law of magnetism?The law of magnetism states that like poles repel and unlike poles attract.
The poles of a magnet refer to the ends of a magnet. There are two poles in a magnet; the North pole and the South pole.
The North pole of a magnet is the end of the magnet that points toward the geographical north when a bar magnet is suspended in the Earth's magnetic field.
The south pole of a magnet is the end of the magnet that points toward the geographical south when a bar magnet is suspended in the Earth's magnetic field.
When two North poles of a bar magnet are brought close to each other, they repel themselves. Similarly, when two South poles of a bar magnet are brought close to each other, they repel themselves.
However, when a North pole and a South pole of a bar magnet are brought close to each other, they attract themselves.

What are the economic concerns over moral issues on GM food and food products?
The main economic concerns are the risks of patent infringement, which could force farmers to rely on giant engineering companies like Monsanto for strains when their crops cross pollinate.
Genetically modified (GM) foods are those derived from organisms that have had their genetic material (DNA) altered in ways that do not occur naturally, such as the introduction of a gene from another organism.
GM is a technology that involves inserting DNA into the genome of an organism. To create a GM plant, new DNA is transferred into plant cells. Cells are typically grown in tissue culture and eventually develop into plants.
The use of genetically modified organisms (GMOs) in seed markets may increase farmer reliance on corporations that control seed prices and supply. Switching from traditional to genetically modified seeds may increase farmer inequality by lagging behind poorer smallholders.

Explain why the pyramid shape is used to represent energy, biomass, and numbers pyramids.
Answer:
Explanation:
The pyramid shape is often used to represent energy pyramids, biomass pyramids, and numbers pyramids because it visually conveys the hierarchical structure and relative proportions of the entities being represented. In an energy pyramid, for example, the pyramid shape can be used to represent the flow of energy from one trophic level to the next, with the largest amount of energy at the bottom of the pyramid and the least amount of energy at the top. Similarly, in a biomass pyramid, the pyramid shape can be used to represent the relative amount of biomass at each trophic level, with the largest amount of biomass at the bottom and the least amount at the top. And in a numbers pyramid, the pyramid shape can be used to represent the relative number of individuals at each trophic level, with the largest number at the bottom and the least number at the top. Overall, the pyramid shape is a useful visual tool for representing hierarchical structures and the relative proportions of the entities within them.

The DNA compliment of the above-mentioned strand is ATA-ATC-TAA-TGA (option C).
What is DNA replication?DNA replication is the process by which DNA makes a copy of itself during cell division.
DNA replication is a very important process that must occur prior to cell division because it ensures that each daughter cell receives the correct amount of genetic material.
The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule with the aid of an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).
The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
Since Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C), this means that if a DNA strand of TAT-TAG-ATT-ACA undergoes replication, the complimentary DNA strand will be as follows: ATA-ATC-TAA-TGA.

What are two ways to restore coral reefs?
An effort to restore the ecological functionality of coral reefs is known as coral restoration. This covers three ways of restoration: biological, physical, and structural.
Strategies for restoring damaged coral reefs use both artificial and natural processes. In locations where the structure is already present, biological restoration often entails increasing the number of living corals on the reef. This is typically done by gathering and repairing naturally damaged coral fragments, growing new coral colonies, raising coral larvae, or transplanting existing coral colonies.
To increase the corals' health, growth rates, or fecundity through physical restoration, the environment in which they are grown must be changed. These techniques include mineral accretion devices or mid-water coral nurseries.
The construction of artificial reefs, sinking of ships, or shifting of rocks or dead coral heads are the most common structural restoration techniques. The objective is to provide more habitat and reef structure for corals and other reef species to grow on.
