-You bury a piece of the stem to produce adventitious roots and then cut the new plant away from the parent plant.

Called the natural layering

These stems are vital and needed for active transportation of the water molecules either for the production of food for the plants or to supply sufficient moisture and hydration for other cellular activities in autotrophs however, the most essential function of the stem is also to support the photosynthetic mechanism of plants which is to make their own food and obtain energy from it called photosynthesis which needs sunlight, carbon, and water.

In which phase will crossing-over occur? A. Meiosis II
B. Metaphase II
C. Mitosis
D. Prophase I

Answers

The correct answer is option D. Prophase I

The crossing over is a phenomena, which occur in the cells undergoing meiosis. In the process of crossing over, the exchange of the genetic material takes place between the sister chromatids. This process takes place in the prophase 1 stage of meiosis 1 in the gametes. The exchange of genetic material between chromatids cause recombination, and hence, genetic variation.

Crossing over occurs in the first stage of meiosis which would be Prophase I.

Answers

Answer:

All the things expect enegry are recycled.

Explanation:

  • When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled.
  • The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.
