Answer:
D. The energy flow is not dependent on any members of the ecosystem
Explanation:
The energy flow in an ecosystem is not dependent on any member of the ecosystem. It is the flow of energy through the food chain, energy is passed from members in one trophic level to members in another or the next trophic level. The flow of energy in an ecosystem is important because it helps in maintaining balance in ecology.
Answer:
Coal is mined in two different ways: from deep underground and in
strip mines. In both cases the land that is mined is leased by the coal companies, while the ownership remains in public hands. Deep mines are reached through a shaft into the ground, through which miners gain access to the coal seam and out of which comes the coal. Strip mines are used when the coal seam is near the surface. The topsoil and other overburden materials are removed by giant power shovels and piled out of the way. The shovels then dig out the coal. After the coal has been mined, there may be environmental reclamation to return the land to its original state, thus allowing others continued use of it for their own purposes. This involves refilling the hole, spreading topsoil, and then planting new vegetation on it.
The epididymis region of the testis do they remain.
<h3>What about epididymis?</h3>
- Each testis has a little, tightly coiled tube linked to it (the male sex glands that produce sperm).
- Male reproductive cells known as sperm travel from the testicles into the epididymis, where they mature and are then stored.
- The epididymis' most obvious job is to move sperm from the rete testes to the vas deferens.
- The immature sperm from the testis is received by the tortuously coiled epididymis, which stores it for several days.
- Sperm is forcibly discharged into the deferent duct during ejaculation from the epididymis' tail.
- Sperm is transported from the testes and stored in the long, coiled epididymis.
- It is seen as a curving structure on each testis' posterior (rear) edge. There are three parts to it.
