The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. I
Westkost [7]

Answer:

C(t) = C_oe^{-kt}

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:

\dfrac{dC}{dt} decrease proportionally to Concentration C

i.e

\dfrac{dc}{dt} \alpha - C

\dfrac{dc}{dt} = -k C

\dfrac{dc}{c} = -k dt

\int \dfrac{dc}{c} = -k \int dt

㏑(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

\dfrac{C}{C_o} = e^{-kt}

C(t) = C_oe^{-kt}

∴

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

C(t) = C_oe^{-kt}

What are your thoughts on climate change? Explain 4-5 sentences
densk [106]

Answer:

I think climate change can be either fake or real. I do believe temperatures are rising, but if you look at the history of the earth, it's gone through many ice ages and changes, so I would assume that it is no big deal. There is no evidence that temperatures are rising at a deadly rate, but weather has been unpredictable for a while now. Then again, these are my thoughts on climate change, so I'm not sure if I'm right or wrong. Hope I gave some useful information!

Alex is participating in a 50 meter dash. Predict the most important chemical process his muscles will rely on during this race.
natta225 [31]

Answer: The correct answer to the question is option E

BOTH ANAEROBIC RESPIRATION AND CREATININE PHOSPHATE BREAKDOWN.

Explanation: 50 meter dash is a race,a form of exercise, energy is required as well as muscle contraction and chemical processes.

Alex muscles will rely on the following chemical processes during the race;anaerobic respiration and creatine phosphate breakdown.

These chemical processes are explained below;

Aerobic respiration uses oxygen to generate energy but unlike aerobic respiration, anaerobic respiration breaks down glucose to provide energy and create adenosine triphosphate(ATP), lactic acid and ethanol.

Muscle contraction cannot take place without the supply of energy by ATP, molecules can store energy in it's phosphate form, this molecule is known as creatine phosphate,when this happens,ATP that is in excess will then transfer it's energy to creatine,this action will produce creatinine phosphate and adenosine diphosphate (ADP) and they will now be stored as reserve of energy that can be used to produce more ATP and thus energy is produced.
