This podcast discusses terrorism issue following with expansion of globalisation. The argument for the paper is having racism in a country, extremism (which are the root of terrorism), opinions about Jihad, refugee crisis and opinion about those refugee crises. In conclusion, the change in leadership attitudes, international cooperation, eliminate racist attitudes among populations and accepting refugees can only tackle this ongoing circle of the problem.
BBQ3a Post, How do the nutrients normally found in soil help plants grow and develop? [5 lines, 5 dots, 1 curve]
Nutrients like carbon, hydrogen, and oxygen are provided by air and water, (represented here by the curved line) but many nutrients for plants (represented by the two parallel vertical lines) have to be found in the soil. These are divided in macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur), which are required in abundance, and micronutrients (iron, chlorine, zinc, molybdenum, boron, manganese, copper, sodium, cobalt), which are required only in small amounts. These are represented by the five dots. When chemicals such as these interact with water, it can change their charges into either cations, which are positively charged, or anions, which are negatively charged. Once in one of these two states, the plant’s roots (represented by the lines at 45 degree angles beneath the soil line, the long horizontal line) can absorb the nutrients and the soil can contain the nutrients as well. When the soil holds more nutrients, it becomes more fertile because these necessary components of plants cover more of the soil’s integral surface area.
