Answer:
b. forward mutation, suppressor mutation
Explanation:
When the nucleotide sequence of an organism is altered, it is called as mutation. It can be caused by DNA damage or replication errors. In forward mutation, the wild type allele is converted to a mutant version such that the gene product is non functional or its not produced at all. Suppressor mutation is the second mutation which reverses the phenotypic effects of the previous mutation. This process is called as synthetic rescue.
Since here gene X was converted into a mutant form by the mutation, it had undergone forward mutation. When gene Y was mutated, the function of gene X was restored which ultimately also restored the phenotype hence it is an example of suppressor mutation.
They do that so when a shark eats something and crumbs come out of its mouth it eats the crumbs
Answer:
The balloon will expand or explode (with enough time)
Explanation:
Charles law states that the volume of a fixed gas is directly proportional to the temperature and pressure. The higher the temperature, the higher the pressure. This will raise the volume, causing the balloon to expand at the very least.
Fossil evidence because these changed occur over long time periods (millions of years).
