Well, D is definitely correct - t<span>hey both share cultures, especially along the border, because they used to be one country in the past.
I'm not sure about the second answer though, perhaps C (</span><span>They both work together as economic partners.) is correct because they do trade a lot. </span>
Explanation:
Radiation means ‘energy that is transported from one spot to another without the need of direct contact between the two locations’, Light in each carries a different amount of energy, this is what we call electromagnetic radiation or electromagnetic waves. Gamma rays are the most energetic, and radio is the least.
<em>In order from longest to shortes wavelenghts we have:</em>
- Radio waves: they are made by various types of transmitters, given off by stars, sparks, and lightning, they have the lowest frequencies (longest wavelenghts) in the electromagnetic spectrum and are used mainly for communications.
- Microwaves: they are extremely high-frequency radio waves (Their wavelength is usually a couple of centimeters) made by various types of transmitters.
- Infra-red waves: they are just below visible red light in the electromagnetic spectrum, they're given off by hot objects.
- Visible lights is the tiny part of the electromagnetic spectrum our eyes can detect.
- Ultra-Violet: this light is given off by the Sun in large quantities. We call it "UV" for short and can also be used to kill microbes.
- X-rays: they are very high-frequency waves that carry a lot of energy. They will pass through most substances, and this makes them useful in medicine and industry to see inside things.
- Gamma rays: they are given off by stars and by some radioactive substances. They are extremely high-frequency waves (the shortest wavelength) and carry a large amount of energy. They pass through most materials.
In the image, I annexed you can see the electromagnetic spectrum with the type of radiations from the shortest to the longest wavelengths.
I hope you find this information useful and interesting! Good luck!
I believe the answer you're looking for is temperature and precipitation.
Climate is based on the amount of rainfall (i.e. a rainforest) or the temperature (i.e. a tropical climate)
After one island has experienced mass extinction of its mainland species, the chances are that the closer and more distant islands will have no consequences when it comes to their equilibrium.
Explanation:
If an island experiences devastating volcanic eruption, and the majority of its mainland species are destroyed, the island will have huge consequences when it comes to its equilibrium number of species. The reason for this is that the equilibrium number of species represents the optimal number of species, or rather the number of species that is capable on surviving on the available resources, not more, not less. With the majority of the mainland species gone, the island will have significantly less species than the equilibrium number of species, so it will take some time in order that number to be achieved.
Because it is an island we are talking about, and mainland species in question, the nearby and more distant islands will not have any consequences on their equilibrium number of species. This is because the species on those islands will not be affected, as they don't have any direct connection with the mainland species of the island in question. Also, the mainland species from the other islands will not be able to migrate in mass numbers toward the island that experienced disaster, but only accidentally and under particular conditions, but still in very small numbers, thus maintain the balance.
