Please, next time check your question carefully, because even if I am right there is possibility that it won't coincide with your options. And if my memory serves me well, the answer on the question is n<span>ot only does topsoil erosion lead to loss of soil fertility, it can also cause water pollution.</span>
The answer is D. 3.33 A
In parallel connected devices, circuits are also placed parallel. It is known that in parallel circuits, total voltage is equal to the voltage of each device.
So, we know that:
Device 1 - R1 = 12 ohms
Device 2 - R2 = 4 ohms
Total voltage - V = 40V = V1 = V2
If V = I × R, for the first device is V1 = I1/R1.
⇒ I1 = V1 ÷ R1
⇒ I1 = 40 V ÷ 12 ohms
⇒ I1 = 3,33 A
Answer:
E) reduce the number of primary producers
Explanation:
The primary producers are the ones that are the basis of any ecosystem on the planet. They have the ability to produce food for themselves, thus they are autotrophs, and they are the ones that are the food source for the primary consumers. With reduction of the primary producers the whole ecosystem will instantly feel the effects. The primary consumers will be left without food, meaning that they will start to die out. The dying out of the primary consumers will lead to dying out of the secondary consumers, and their dying out will result in the dying out of the predators, or rather the tertiary consumers. The end result will be a collapse of the ecosystem, which will then be inhabited by other organisms, first through the primary succession, and then through the secondary succession, resulting in a new and different ecosystem.
Answer:
Sympatric speciation
Explanation:
There may be more than one answer here, but concerning speciation, sympatric speciation can't occur because of the geographic isolation (must be living in the same environment for this to occur).
