Answer: Keystone species
Explanation: A keystone species is a species which occupied a niche so central in the ecosystem that it has a disproportionately large effect on its environment and other species in it.
The coral's function in its ecosystem is so vital that if you were to remove it, the entire community would be drastically altered beyond recognition.
The coral serves as the base structure of its ecosystem.
That is to say that many corals are hermatypic(they form reefs). This reef serves as the environmental structure of the Coral's ecosystem. Built in and around it is a very biodiverse biotic environment. The coral not only serves as a hiding place and habitat for many marine organisms including fish, clams, lobsters, etc. It serves as resting place for larger animals like turtles and also serves as hunting sites for other animal species.
The most common way of determining a keystone species, is to see what happens when that species is removed from the ecosystem. Coral have shown to be so central to their ecosystem that the bleaching of coral reefs due to tourism and climate change causes a massive loss to biodiversity. And this is quite significant as reefs are the most biodiverse marine habitats.
The following tests can determine the mineral in a rock specimen:
1. How does the rock crumble or split under pressure?
2. What is the texture of the rock?
3. Observing it under a magnifying lens.
4. Determine the color of the rock
Test 1 and 3 determines if the rock is granular and the types of grains in the rock. Test 3 also determines if the rock has layers hence sedimentary rock.
Determining whether color of the rock is dark or light also helps identify the mineral and type of rock.
Bi means to cut into two parts.

Answer:
The correct answer is c. the common ancestor of coyotes and domestic dogs is more recent than the common ancestor of foxes and domestic dogs
Explanation:
The Canidae family includes foxes, wolves, coyotes, jackals, foxes, and domestic dogs. Both dogs and coyotes are evolved from ancient wolves and all three can interbreed to produce hybrids.
Dogs are evolved from gray wolves and then domesticated by humans. Humans did the selective breeding of dogs which resulted in artificial evolution of dogs.
Coyotes are evolved from eucyon which was a primitive wolf. Most scientists believe that<em> C. lepophagus</em> is the ancestor of wolves, coyotes, and dogs. Red fox can not interbreed with dogs, coyotes, and wolves that shows that it does not share a more recent ancestor with these three.
Therefore, the correct answer is c.
