The energy that can be renewed again and again is known as renewable source of energy. Example : water, sunlight, wind et cetera.
The energy cannot be created again,once destroyed is known as non renewable source of energy.
The energy obtained from coal is non-renewable.
Energy obtained from burning plant waste is renewable
Energy obtained from water spring inside the earth is renewable.
Energy obtained from natural gas is non renewable.
Where are the answers?? Lol
Answer:
<em>B. Different crops could be grown on the same land.
</em>
Explanation:
Crop rotation is the process of growing different plants in the same land according to the season. Various kinds of plants require various sorts of supplements from the soil.
Changing crops on a regular basis enables the land to stay rich in nutrients, since not the majority of similar nutrients are being utilized each season. Crop rotation likewise fights against the powers of soil erosion. It also helps to improve the stability of the soil by shifting back and forth between harvests with profound roots and those with shallow roots.
Answer:
- Diploid → Prophase, metaphase, and anaphase
- Haploid → Telophase
Explanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
