<span>Particularly the skeletal muscles at rest
gain most of their energy from the aerobic respiration of fatty acids. Hence
fatty acids provide the majority of the energy for muscle metabolism when a
person is exercising at 25% of VO2max. However, the motor neuron is at rest
when a neuron is not receiving any input there will be a potential difference.
Thus, the potential difference measured when the neuron is inactive and it is
caled the resting membrane potential. </span>
Answer:
It could happen through mutation
Explanation:
<em>A segment of DNA after many cell divisions could have more base pairs than it originally did as a result of mutation.</em>
Mutation is generally defined as a sudden change to the DNA sequence of a cell. This change could be of difference forms, including:
- <em>Addition of bases</em>
- <em>Deletion of bases</em>
- <em>Substitution of bases</em>
<u>Addition of bases to a DNA will generally lead to a longer base pairs in the DNA, deletion will lead to a shorter base pairs while substitution will only lead to a change in the base sequence without any change in the length of the DNA.</u>
When continents broke apart from Pangaea lots of different species got separated to different parts of the world. The animals and other living things had to have learned how to adapt to the different climates or they would die and go extinct.
The magnitude, or extent of the force applied to an object at rest or in motion will determine the rate of the acceleration for that object.
