Mutualism: <span>The bee and the flower. Bees fly from flower to flower gathering nectar, which they make into food, benefiting the bees. When they land in a flower, the bees get some pollen on their bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating the plant. This benefits the plants.
</span>Parasitism: Fleas and dogs. <span>Fleas harm their hosts, such as dogs, by biting their skin, sucking their blood, and causing them to itch.
</span>Commensalism: The relationship between cattle egrets and cattle.<span>The cattle egret will eat insects that have been disturbed when the cattle forage. One species benefits while the other neither benefits or are harmed.
</span>Predation: The relationship between lions and zebras. The predator, the lion, kills and feeds on the prey, the zebra.
Competition: <span>One example of competition between two organisms would be chipmunks and squirrels. They compete for nuts to be able to feed themselves and survive.</span>
Answer:
Explanation:
Certain types of volcanic ash do not dissolve easily in water. Instead, they clump on the surface of the ocean in pumice rafts. These rafts can clog salt water intake strainers very quickly, which can result in overheating of shipboard machinery dependent on sea water service cooling.
Answer:
Option D, Continents cannot cut through the ocean floor.
Explanation:
It was believed earlier that oceans were the land bridges that used to connect different geologic plates of planet earth earlier, had now sank down and thus there exists no connection between the tectonic plates. Therefore, without any link or connection, continents cannot cut through the ocean floor.
Also as per the Land Bridge Theory , there has been continuous shifting of dry land due to which identical land species on different continents were found.
Hence, option D is correct
Answer:
The correct statements are options C, E and F.
Explanation:
The SDS-PAGE refers to a broadly utilized technique for distinguishing proteins. The SDS or the sodium dodecyl sulfate refers to an ionic detergent. The SDS-protein complexes possess negative charge with identical charge to mass ratio such that when the proteins are run on the gel they are distinguished on the basis of their size.
As the SDS entices a negative charge to the proteins, the migration of the proteins takes place towards the positive electrode. The migration of protein takes place on the basis of the size. Thus, smaller proteins seem to migrate quickly via the gel in comparison to the bigger proteins. The binding of the protein takes place with about 1.4 times its mass of SDS resulting in the formation of a large overall negative charge.
