What are the factors that contributed to the success of pteridophyte as land plant
Anna35 [415]

Two factors contributed to the success of the pteridophytes: the extreme miniaturization of the gametophytic generation and an important development of the sporophytic generation (development of the tree forms).

Pteridophytes are a group of plants that peaked in the Carboniferous (-300 million years). It is the first great terrestrial plant civilization. These plants would have appeared in the Devonian -400 million years ago, perhaps from certain primitive terrestrial plants which, unlike bryophytes, would have favored the diploid generation on the haploid generation.

Particularly well adapted to terrestrial life, they have created, thanks to the development of tree forms, immense forests whose fossilization is at the origin of coal deposits.

Pteridophytes are at the origin of an evolutionary lineage based on the extreme miniaturization of gametophytic generation and an important development of sporophytic generation, leading to all tracheophytes including current flowering plants. Pteridophytes are well adapted to terrestrial life, however fertilization still requires the presence of water since male gametes are swimmers.

Explain five ways in which goat production contribute to the economic development of your country​
Olegator [25]

Answer:

Sheep and goats are important livestock species in developing countries. Of the world's 1,614million sheep and 475 million goats, 65% and 95%, respectively, are located in developing countries. Fifty-three percent of the total small-ruminant population in the developing countries is found in Asia, particularly in India and Pakistan, 33% in Africa, and 14% in Latin America (FAO, 1984).

Goats are hardy and well-adapted to harsh climates. Due to their grazing habits and physiological characteristics, they are able to browse on plants that would normally not be eaten by other livestock species. Thus, the presence of goats in mixed species grazing systems can lead to a more efficient use of the natural resource base and add flexibility to the management of livestock. This last characteristic is especially desirable in fragile environments.

Sheep and goats contribute to a broad range of production systems. The most common system throughout the developing countries involve either the extensive system with large herds and/or flocks grazing on arid and semi-arid rangelands or the intensive system with smaller herds and/or flocks kept in confinement, mostly in the humid tropics.

What do crops of the green revolution need in order to produce higher yields?
Airida [17]

Answer:

These crops where improved  with technology, production of high-yielding variety, and improve farm practices. All these ensured  the crops of green revolution had increase yield.

Explanation:

Through  genetic engineering, high-yielding variety of cereals e.g wheat, maize, rice, were genetically engineered so that certain features which enhanced increased productivity were selected for.

Use of fertilization, the adoption of mechanization,good cropping and farming system are other factors which enhanced yield of these crops. Specifically, these crops were modified to enhance their Nitrogen uptake, which promotes rapid growths.
