Answer:
A: Two different forms a plant can have
Explanation:
Rather than saying forms, I would say that Sorophytes and Gametophytes are a type of plant generation. Plants can either be diploids - Sorophytes (these kind contain 2 chromosomes set and use meiosis to produce spores) and haploids (they use mitosis to divide the cells)
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.
Answer:
Cultivation of crops and tillage practices.
Explanation:
Farming of crops and tillage practices on the grasslands depleted grassland that are present across North America because the lands are converted and used for the production of food crops in order to fulfill the feed the existing population. More and more land is converted from grassland to the cultivation of crops that leads to lower area for the grazing of animals which results in decrease population of animals such as sheep, goat and cow etc which depends n these grazing regions for food.
