Answer:
Thoracic cage and vertebral column.
Explanation:
The bones of the head and the bones that make up the trunk of a vertebrate organism form the <em>axial skeleton. </em>
In the case of humans the axial skeleton consists of a total of 80 bones which are broadly organized into 6 parts:
1. Bones of the skull
2. Middle ear ossicles
3. Hyoid bone
4. Thoracic/rib cage
5. sternum
6. Vertebral column
The circulatory system will make the heart pump faster, moving blood, oxygen, and nutrients around the body. the excretory system will excrete waste like sweat through the skin, maintaining a steady body temp.
Answer:
The mutation will be fixed by genetic drift.
Explanation:
Genetic drift is the change in the allele frequencies in a population that occur randomly. It is an evolutionary process (like natural selection), that is associated with the reduction in genetic diversity by the fixation of rare allelic variants and neutral mutations. In this example, this point mutation is neutral since, according to data, the population is evolving by genetic drift. Moreover, it is also important to note that a mutation that involves one nucleotide is also called Single Nucleotide Polymorphism (SNP).
