Answer:
lead pencils (graphite)
fertilizer (potassium, sodium, calcium)
chalk (gypsum)
flashbulb (zirconium)
window glass/mirrors (silica)
table salt (halite)
Explanation:
Answer:
The answer is "runoff from fertilizer".
Explanation:
The fertilizer is any natural or synthetic material, which is applied with soil or tissue of plant species and provides one or more plant foods, which are necessary for plant growth.
Due to the high durability and excessive irrigation use, nitrate fertilizers, which provide high solubility, as well as the nitrate ion throughout the finishes the product and readily drained away, that's why the given choice is correct.
Answer:
Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations. Artificial selection works the same way as natural selection, except that with natural selection it is nature, not human interference, that makes these decisions.
Explanation:
Answer: Temperature on monday morning is 319,5K
Explanation: This is an example of Gay Lussac law on gases which states that at constant volume, pressure and temperature are directly related, so if one raises the other one does as well.
The equation that follow the law is :
P1 / T1 = P2/T2 where 1 is the initial pressure and temperature and 2 is the final state.
In this equation, values have to be expressed in atm for pressure and Kelvin for temperature.
The missing value is T2 (monday temperature), so we have to clear it from the equation
T2 =P2.T1/P1
Replacing values:
T2 = 1,073 atm . 338K /1,135 atm
T2 = 319,5 K
