<u>Answer:</u> Mutations are the most fundamental way to add new genes to a gene pool.
<u>Explanation:</u>
Mutation refers to the process through which the normal sequence of altered. It may be either acquired or hereditary. It leads to addition of new genes to a gene pool.
The reason for not considering other statements as true are:
1. It is the hereditary mutation that are passed form parent to offspring's and acquired mutation is caused by external factors.
2. Acquired mutation are caused by external factors such as radiation.
3. Germ line mutation are important to evolution because they can be inherited.
 
        
             
        
        
        
The RYR1 gene is responsible for producing the protein ryanodine receptor 1. This protein transport calcium ions to the cells for muscle contraction. When this receptor remains open for a long time, you would expect an excess of calcium ions which would result to muscle rigidity. The excess calcium ions would also increase body temperature and produce excess acid.
        
             
        
        
        
In ecology, a group of particular organisms which live in a community is called POPULATION.
For instance, all the number of lions which live in a community make up the population of lions in that community. Populations of different species of animals that are found in that area combine together to form the community.
        
             
        
        
        
<u>Answer:</u>
<em>Community and ecosystem levels of organization are the main focus areas of Vitor Becker’s work.
</em>
<u>Explanation:</u>
<em>Serra Bonita reserve complex was established by Vitor Becker and his wife Clemira Souza in the Atlantic forest of Brazil.</em> He studied agronomy and forestry and has a Ph.D in entomology.
Becker realized that the Atlantic forests are largely destroyed. After retirement Becker and Souza settled in the <em>Serra Bonita mountain region and using their savings they bought land in the region and converted the area into Serra Bonita reserve complex.
