Answer:
Risk management
Explanation:
Risk communication is exchange of the advice, real-time information and the opinions between the experts and the people which are facing threats to their economic, health, or well-being.
Risk assessment is overall process where the hazards and the risk factors which have potential to cause the harm is identified.
Risk perception is subjective judgement which people/ experts make about characteristics and the severity of the risk.
Risk management is evaluation, identification and prioritization of the risks followed by the coordinated and the economical application of the resources to monitor, minimize and control probability of the unfortunate events.
Thus, Option D is correct because in risk management, a Quantitative Solution is given to decrease risk level like to recycle the plastic.
Answer: b) virus
explanation: viruses depend on the host cells that they infect to reproduce or “replicate”. though they can survive outside of a host, they cannot reproduce without a host.
Answer:
Saturated fat occurs naturally in red meat and dairy products. It's also found in baked goods and fried foods. Trans fat occurs naturally in small amounts in red meat and dairy products. Trans fat can also be manufactured by adding hydrogen to vegetable oil.
D. the law of conservation of energy
84.24 g of water (H₂O)
Explanation:
We have the following chemical reaction:
2 H₂O → 2 H₂ + O₂
Now we calculate the number of moles of products.
number of moles = mass / molar weight
number of moles of H₂ = 50 / 2 = 25 moles
number of moles of O₂ = 75 / 32 = 2.34 moles
We see from the chemical reaction that for every 2 moles of H₂ produced there are 1 mole of O₂ produces for every 25 moles of H₂ produced there are 12.5 moles of O₂ but we only have 2.35 moles of O₂ available. The O₂ will be the limiting quantity from which we devise the following reasoning:
if 2 moles of H₂O produces 1 mole of O₂
then X moles of H₂O produces 2.34 mole of O₂
X = (2 × 2.34) / 1 = 4.68 moles of H₂O
mass = number of moles × molar weight
mass of H₂O = 4.68 × 18 = 84.24 g
