Answer:
The correct answer will be option-Telomerase is an enzyme that increases the length of linear chromosome ends
Explanation:
Telomerase is a reverse transcriptase enzyme which adds the length of DNA by adding the guanine-rich repetitive sequences called telomeres at 3' end of the DNA.
The enzyme not only adds the telomere but also maintain its length in the organism. The telomerase activity possesses several roles one of which is that it protects the end of the DNA from DNA damage and neighbouring chromosomes.
Since telomerase adds the repetitive sequences at the end and thus increases the length of the DNA thus is the correct answer.
Answer:
stamen produces pollen ovules develops into fruit
Explanation:
Answer:
1. They provide home and shelter for millions of species of marine organisms.
2. They play a role as nutrient recyclers and in carbon and nitrogen fixation.
3. They are vital in the marine food chain as they are the main source of essential nutrients.
Explanation:
Cnidarians are extremely ecologically important organisms that play a significant role in the animal kingdom and nature.
For instance, coral reefs, which are built by hundreds to thousands of cnidarians, provide home and shelter for millions of species of marine organisms, from small crustaceans to large fish such as sharks. Furthermore, they play a role as nutrient recyclers and in carbon and nitrogen fixation. In addition, they are vital in the marine food chain as they are the main source of essential nutrients such as nitrogen.
Today, these organisms are threatened due to human activities and anthropogenic climate change, so it is fundamental to develop better strategies to protect and restore them.
Peer review is a means of quality control for scholarly journal articles and books. It is the evaluation process of academic, scientific and professional work done by other individuals working in a similar field. Sometimes, the articles published in academic Journals are also referred as scholarly journals.
Hope this helps.
