What passes through a cell using passive transport?

Biology
1 answer:
Tanzania [10]3 years ago
7 0
Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.

Which objects allow humans to access groundwater? Check all that apply.
Masja [62]
<h2>Answer:</h2>

<u>The objects that allow humans to access ground water are:</u>

  • <u>A spring</u>
  • <u>a well drilled into an aquifer </u>
  • <u>a well drilled below the water table</u>
<h2>Explanation:</h2>

Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..

Red foxes have three different types of coat color: red, cross, and black/silver. These coat colors are controlled by a single l
Anna [14]

Answer:

74%

Explanation:

The frequency in such cases (diallelic cases) is estimated by following formula which is attached in the image:

So as per our question, the frequency of the "R allele" as per data given below will be as under:

58 red-phase (RR)

32 cross-phase (RS)

10 black/silver-phase (SS) foxes

Total plants = 58 + 32 + 10 = 100

f(R) = 58 x 2 + 32/ 2 (58+32+10)

    = 116 + 32 / 200

     = 148/200

     = 0.74 i.e. 74%
