Answer:
Eukaryotic cells are cells with a nucleus (such as animal and plant cells) whereas Prokaryotic cells are cells without a nucleus (such as a bacterium cell)
Explanation:
Answer:
"Segmental deletion" seems to be the correct answer.
Explanation:
- A special sequence range of approximately bp scattered segmental transposable elements containing DNA over a system or zone of bp edge.
- About bp, including that of the special sequence DNA, is destroyed if recombination happens between some of the segmental duplications.
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.
Some organisms may not be able to survive.
