Answer:
short-grass, unpalatable ruderal and shrubs species.
Explanation:
Overgrazing can be defined as the intensive grazing of farm animals in a restricted area of land, usually over a long period of time. During this period, there is no recovery rate for emergence of newer species. Effects of Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion.
In an area where grazing is heavy or overgrazing occurs, short-grass species usually less than 2-3 inches tall exists in the overgrazed areas. In other parts of the world, overgrazed pasture is typically taller than sustainably grazed pasture, with grass heights typically over 1 meter and dominated by unpalatable ruderal and shrubs species.
Answer:
The weeds will become tolerant to the herbicide through repeated exposure.
Explanation:
Genetic engineering refers to the procedures that are used to change the genetic composition of an organism by supplementing the desired genes. The herbicide-resistant crops are developed in order to withstand specific broad-spectrum herbicides that destroy the surrounding weeds, however, leave the cultivated crop intact.
The cultivation of herbicide-resistant crops encourages and substantially enhances the application of herbicides, leading to overuse of herbicides, in order to maintain the production of crops. However, this overuse application of the herbicides will eventually result in the generation of weeds that become resistant to herbicides.
The magnetic marbles will attract to each other despite being mixed in with the ordinary marbles. The chance they will touch depends on how many marbles are in the jar and how many magnetic marbles were put in.
Chloroplast and cyanobacteria are thought to be related as it is the only eukaryotic algae having chloroplast because they synthesise food by photosynthesis
