Answer:
immediately
Explanation:
The ants move independently to search food from the nest, but at the same time they go away from the nest, they leave a way of pheromones, this is their mechanisms to return to the nest.
In average, the ants could take like 100 or 200 meters from the nest to search food, so 7 meters is a very small distance, and with the way of pheromones, they will return to their nest easily.
In order to survive the winter, monarch butterflies "migrate to warmer areas".
<u>Option: B</u>
<u>Explanation:</u>
- The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
- This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
- Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
- If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.
The chemical nature of an atom, that is , the chemical properties of a specific element, is determined by the number of protons in the nucleus<span>. This number of protons is called the </span>atomic number<span>. The mass of the atom, its atomic mass, depends upon both the number of protons and upon the number of neutrons present in the nucleus (remember that the mass of an electron is so small that it is simply ignored for the purpose of establishing the atomic mass).</span>The difference between atoms, ions and isotopes is the number of subatomic particles.<span> An atom is the basic building block of matter, the smallest molecule of an element that exists and that cannot be chemically divided by ordinary means. Each atom is comprised of protons, neutrons and electrons. In ions, the number of electrons differs, and in isotopes.
