The answer is E because heart is circulatory and brain is part of your nervous system.
The right answer is inversion.
Inversion is a genetic mutation characterized by the end-to-end reversal of a portion of chromatid on a chromosome.
In other words, it is a double break then it is replaced after rotation of 180 ° of a chromosome segment (backward insertion).
We distinguish :
Paracentric inversions: The centromere in the chromosome is not included in the inversion.
Pericentric inversions: The centromere is included in the inversion which transforms a metacentric chromosome into an acrocentric chromosome.
A lava fountain is an example of the amount of heat stored in the Earth. Geysers, lava mountains and hot springs are all natural examples of geothermal energy.
