Environmental science addresses recycling strategy so we utilize our natural resources efficiently. It also provides us with knowledge on how to lead an eco-friendly lifestyle
Answer:

Explanation:
From the given information:
At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.
Deriving the equation:
decrease proportionally to Concentration C
i.e




㏑(C) = -kt + λ
where,
λ is the integration constant.
Integrating at t = 0, concentration of blood = Co g/mL
C(0) = Co
㏑(C₀) = 0 + λ
λ = ㏑(C₀)
From ㏑(C) = -kt + λ
㏑(C) = -kt + ㏑C₀
㏑(C) - ㏑C₀ = -kt


∴
The concentration of drug in blood at any time t is:

Answer:
pseudopodia(false legs)
Explanation:
a protrusion formed by the amoeba towards its food to engulf it...you know it has no particular shape so it uses false legs
Food chain- is a diagram that shows how food energy moves from one organism to another in an environment. It begins with the plant life and ends with animal life. Plants get eaten by animals and animals eat other animals.
