Answer:
2, 3, 1
Explanation:
For logistic population growth, the initial growth is slow while the population is trying to get acclimatized to the environment but the growth increases exponentially once it is done acclimatizing. The exponential growth continues until the carrying capacity is reached and then starts to fluctuate around the carrying capacity.<u> The carrying capacity signifies the maximum size of the population that the environment can support based on the resources that it has.</u> Hence, the logistic population growth curve forms a S shape.
In summary, the correct order of events is:
- <em>The population increase begins to slow</em>
- <em>The population increases exponentially</em>
- <em> The population fluctuates near carrying capacity</em>
Therefore, the order is 2, 3, 1.
Answer:
Some kinds of atoms that are found in DNA must be left out of the models. DNA has so many atoms that the size and cost of a model could be too great. It is impossible to distinguish different kinds of atoms with models.

Answer:
It is important to understand the difference between rotations and revolutions. When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.
