Whales play an important part within the marine ecosystem, and if they were to disappear, the delicate balance of nature would be disrupted. According to Scitable, every time a whale dies, it leaves behind a carcass that provides food and vital nutrition for literally hundreds of marine life organisms. For instance, species of scavenger crustaceans and worms feast upon whale carcasses for sustenance.
Other species of fish, including sharks, also obtain food from a whale carcass. Without this bountiful source of food, certain parts of the ocean would cease to thrive.
Living whales also heavily contribute to the marine ecosystem in the form of whale feces. According to the Columbia Basin Fish and Wildlife News, a study found that whale feces is filled with rich nutrients that include nitrogen, which stimulates the growth of plants. Organisms, such as plankton, that feed the ocean food chain also benefit from tons of whale feces floating on the ocean's surface. The disappearance of this source of natural nitrogen is likely to have a negative effect on plant and food production.
An overpopulation of sea lions would quickly be evident as soon as the whales that prey on them vanished. Likewise, the economies of Canada and the United States would suffer from a lack of tourist dollars because whale watching is very popular.
It would be the closest as the massive glaciers in that area melted and retreated. Freed from the enormous weight of ice, the land level gradually rose over several thousand years and the waters simply drained off into the ocean, leaving what is now Lake Champlain and a few river valleys.
<span>The correct answer is B. Rhizoids absorb water and nutrients, while fruiting bodies release spores.</span>
<span>
Rhizoids of Fungi are similar to root hairs on vascular land plants. Rhizoids, release digestive enzymes and absorb digested organic material, so it is a feeding organ.</span>
<span>Fruiting body or sporocarp is a structure that is part of the sexual phase of a fungal life cycle and it contains spore-producing structures.</span>
Answer:
The agent causing the pneumonia, where bluish-green pus was found, is most likely Pseudomonas aeruginosa.
Explanation:
Pseudomona aeuriginosa is a gram-negative bacteria that is one of the main causes of hospital-acquired infections, including pneumonias in mechanically ventilated patients.
One of the characteristics of P. aeuriginosa is the formation of a bluish-green pus, since it has the capacity to form cyanide-based blue pigment upon contact with the organic tissues it infects. This is the reason why previously P. aeruginosa was called a pyocyanic bacillus.
<em> The other options are not correct because the only bacterium that produces blue-green pus is P. aeruginosa.</em>
Well scientist have made the microscope and telescope and we have discover new bacteria and new plant(s) which has help a lot <span />
