Answer: Transport proteins act as doors to the cell, helping certain molecules pass back and forth across the plasma membrane, which surrounds every living cell. In passive transport molecules move from an area of high concentration to an area of low concentration.
Answer:
they need to be able to maintain their salt content, thru osmoregulation
Answer:
t = ln (N/N°)/(-0.0239)
Explanation :
The decay law is represented as
N = N°e^-kt
Where N is the final number of atom,
N° is the initial number of atoms
k is the decay constant
t is the half-life.
From the above we have,
N/N° = e^-kt
take ln of both sides
ln (N/N°) = -kt
t = ln(N/N°)/-k
At half life, N/N° = 1/2
Therefore, t = (ln 1/2)/-k
t = -0.693/-k
But t = 29 sec
29 = -0.693/-k
k = 0.0239 s^-1
Therefore,
The formula will be
t = ln (N/N°)/(-0.0239)
<span>The Answer would be D: Mesquite Shrubs as these are plants that produce their own food (called autotrophs) Plants use solar energy, convert it to chemical energy and these can be taken up by other consumers like the Coyotes, Cactus finch and Beaded lizards. These plants are eaten by primary consumers that are in turn eaten by secondary and tertiary consumers. So from the given list, the Mesquite Shrubs would begin the flow of energy through a desert food web</span>
