Spores are the reproductive cells that are better adapted to disperse or spread bryophytes and ferns to other places. They can be dispersed by wind.
Answer:
Deletion in a nearby gene, chromosome breakage, and translocation of the gene to a heterochromatic location.
Explanation:
Transposable components (TEs), also known as "jumping genes," are DNA sequences that moves starting with one area on the genome then onto the next, in some cases making or reversing mutation and changing the cell's hereditary character and genome size.
At the point when the transposon is extracted from the original site, it may remove a portion of the gene sections alongside it. This prompts the presence of a serious phenotype. Transposable components can likewise cause chromosome breakage. On the off chance that the whole gene is moved alongside the transposon to a heterochromatic location, the gene gets silenced
Answer:
Mutagens can be described as substances which cause mutation. Mutations can be described as any changes in the DNA of an organism.
Mutations can be introduced by chemicals or naturally.
Mutagens which can cause mutations are:
- X-rays
- Ultraviolet radiation
- Chemical mutagens such as Alkylating agents such as ethylnitrosourea.
- Certain Alkaloid
- Bromine
B. an ecosystem
An ecosystem contains a community (several species of organisms) and the environment including air, water, and more.
