Can start a fire( rubbing to rocks together) and friction is used when you hit the brakes on a car( the pad pushes down on the tire). Good luck!
Answer:
The correct answer is - polyploidy.
Explanation:
Speciation can be two types allopatric and sympatric speciation. Sympatric speciation is the process of speciation is developing the new species that diverged from the common ancestral species while the ancestral and developed species both can share the same place or geological area. The main cause of such speciation is due to the change in their genetic level more than environmental conditions.
In this case, the frog's species show differences in their ploidy level as well as their mating call but polyploidy is the most likely the difference that evolved first rather than females call for mating.
Thus, the correct answer is - polyploidy.
The statement that is true about renewable energy resources is that there are endless supplies of all renewable energy resources (option B).
<h3>What is renewable energy resource?</h3>
Renewable energy is the energy that is collected from renewable resources such as;
- wind power
- hydropower
- solar energy
A renewable resource is that natural resource that is replenished by natural processes at a rate comparable to its rate of consumption by humans or other users.
This suggests that renewable resources have an unlimited supply and will likely not be exhausted. This is unlike the non-renewable counterparts like crude oil, gas etc.
Therefore, the statement that is true about renewable energy resources is that there are endless supplies of all renewable energy resources.
