Answer:
Our planet is called Earth
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.
The mesoderm is one of the embryonic layers together with the ectoderm and endoderm. The germ layer that gives rise to muscle is the <u>mesoderm</u>.
<h3>
What is the mesoderm?</h3>
Three embryonic layers are present in the blastoderm after segmentation. One of them is the <u>mesoderm</u>, which is located between the ectoderm and the endoderm.
Different tissues and cells are formed from the mesoderm, such as muscular, skeletal, circulatory, and connective tissues.
The correct anwer is mesoderm. The embyonic germ layer that gives rise to muscle is the mesoderm.
