Answer:
The correct answer is filtration.
Explanation:
Filtration refers to a physical procedure, which is used to distinguish two or more constituents because of their distinct size of particulate or unit. On the other hand, distillation refers to a chemical procedure, which is used to distinguish two or more constituents because of the difference between their boiling points, however, this process is generally used in the case of liquids.
Thus, it is clear that with the help of the filtration process, one can separate the acorns, leaves and twigs from the soil. Hence, the correct answer is filtration.
Answer:
B. Corundum
Explanation:
Using the Mohs scale of hardness, the mineral has a hardness greater than 6.5 (Steel nail) but less than 8.5 (Drill bit). The corundum has a hardness of 9.0, which means it cannot be scratched by a drill bit, but all the other choices have a hardness scale less than 6.5 but the mineral was not scratched by the nail. So the best answer would be B.
Specialised cells mean they have one specific job, for example cells in the alveoli (in the lungs) would be specialised to transfer oxygen into the blood. An unspecialised cell would be an embryonic stem cell which can become any cell to suit the needs of the organism, which is how a small cluster of cells in a zygote becomes a full human with all the organs and such.
Answer:
it helps the process go much faster and more efficient
Explanation:
Answer: overpopulation of predators
Explanation: Overpopulation of predators is the correct option. Predators are the organisms which kill other organism so as to obtain them as food. The organism being killed is called as the prey.
If the population of the predators increase this will lead to the extinction of many species of prey. As it is evident that every organism in the ecosystem has a typical role to play. Therefore, it can be said that role of prey will not be performed and this may lead to disturbance in the ecological balance.
