Answer:
The artificial reef would decrease erosion of the coastline.
Explanation:
Artificial reefs are created in area where there is little uderwater topography or near established coral reefs to imitate or even substitute for natural coral reefs where they are absent or endangered due various factors which are mostly human in nature. The artificial serves to provide a habitat for marine organisms and ensure more biodiversity around the area by providing shelter from predation and surfaces for encrusting organisms such as corals and sponges to grow on. The growth of these lower level food chain organisms attract larger predator organisms thereby increasing the biodiversity in the area.
Artificial reefs are made from a variety of materials such as shipwrecks, construction debris, oil rigs, concrete, and any other man-made objects. Since reef structures protect shorelines against waves, artificial reefs would decrease the erosion of the coastline providing benefit to the people living along the coastline by preventing the destruction of beaches and coastal property,
The <em>Hydra </em>offspring will also have 30 chromosome.
Explanation:
- Budding is a method of asexual reproduction.
- Asexual reproduction takes place through mitosis where diploid cells divide to give rise to identical cells with same chromosome number.
- Hydra reproduces through budding thus, if the parent hydra has 30 chromosome then the offspring will also have 30 chromosome.
The answer is C. a tube that extends from a bacterium.
<h3><u>Answer;</u></h3>
D) India was a separate continent until forty-five million years ago.
<h3><u>Explanation</u>;</h3>
- <em><u>Continental drift serves as one of the evidence of evolution. Different kinds of animals and plants live in different parts of the world. This is true now, and it was true in the past. </u></em>
- Therefore, when a fossils of the same animal or plant is found on different continents, then that is evidence that those two continents may have been a single continent when those fossils were formed.
- Fossils show that the continents drifted because similar fossils were found where the continents were together millions of years ago.
I'm afraid none of those is correct. The correct option would be subspecies. Subspecies are different variations, one could say, of a same organism.
Hope it helped,
Happy homework/ study/ exam!
