Epiglottis is the flap of cartilage that covers the opening of the larynx
Answer:
c. individuals of a single species that live and interact in one area
Explanation:
When some organisms belonging to a single species live together in an area, they make a population. Since members of a population belong to the same species, they are able to interbreed among themselves to produce viable and fertile progeny. They have the same resource requirement and interact with each other. All the plants of <em>Mangifera indica</em> present in an area make a population. Likewise, a group of <em>Panthera tigris</em> living in a forest together makes the tiger population of that area.

Answer:
In the n=1 energy level, the atom has 2 electrons
Explanation:
Electrons orbit the nucleus of an atom in multiple rings (energy levels). The first ring of the electron can only hold 2 electrons. After that, electrons are added to the second ring. Excluding the first ring, all other rings can hold a maximum of 8 electrons.
For example, Oxygen is an atom with 6 electrons. The first energy level contains 2 electrons, and the second energy level contains 4 electrons. The second energy level has room for up to 4 more electrons.
In your example of an atom with 15 electrons, there would be 2 electrons in the first ring, 8 electrons in the second ring, and 5 electrons in the third and final ring.
To summarize, all atoms have a first energy level containing 2 electrons, and all other energy levels can contain 8 electrons. This is true no matter the number of electrons.
It might involve changing to survive different temperatures such as when lakes freeze over or a lake is too hot.
