Answer:
the population is evolving.
Explanation:
if any sort of change is happening in a variable, gene etc.; then it means that the population is evolving in a certain way.
As human travel increases , the number of introduced species likely increases .
<h3>What is species and how human travelling can increase the number of introduced species?</h3>
- As humans will start moving more from one place to another there will be more species number.
- The number of introduced species will increase sharply seeing the increase in the number of human population doing migration and travelling.
- The breakdown of regional distinctiveness leads to increase in the travelling period of the humans .
- And most importantly the introduction of new species will increase and will be impacted by the human who have come from elsewhere for either travelling purposes or migration purposes.

Answer:
The correct order is -
a. 5 > 3 > 4 > 1 > 2 .
Explanation:
In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.
Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.
Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .
Sound is a wave and will have different frequencies when the wavelength changes. When the wavelength changes the amplitude will rise or fall creating different pitch.
