Answer:

The alpine biome is found on five of the seven continents; the taiga biome is only found on three.  Both the alpine and taiga biomes have cold winters with temperatures below freezing and summers that are warm in comparison. The taiga biome has a much higher temperature range in the summer than the alpine biome.

sineoko [7]

Answer:

A. Actin filaments and microtubules

B. intermediate filaments

Explanation:

Actin filaments and microtubules are two major building blocks that form part of the cytoskeleton in all eukaryotic cells. Both actin filaments and microtubules play a fundamental role in the dynamics of the cytoskeleton, and they are involved in many essential cellular processes including, among others, mitosis, cytokinesis, intracellular transport, cell signaling, etc. Moreover, intermediate filaments are very stable structures found in animal cells, where they extend from a ring around the cell nucleus to the plasma membrane in order to provide consistency and shape to the nuclear envelope.

A plate moves 200 m in 10,000 years. What is its rate in cm/year?
schepotkina [342]

Answer:

1m = 100cm

200m = 20000cm

10,000years = 20,000cm

1 year = 20,000/10,000

= 2cm

It's rate is 2cm/year

The answer is option b.

Hope this helps.

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}
