Answer: Add more of the proteins to the plasma membrane and measure the rate of the particle movement.

Explanation:

<u>A membrane protein is a protein molecule that is attached to or associated with the membrane of a cell or organelle.</u> Membrane proteins can be grouped into two groups based on the way they associate with the membrane.:

  • Integral membrane proteins are permanently rooted within the plasma membrane. They perform many important functions; these include the transport of molecules across the membrane.
  • Peripheral membrane proteins are proteins that are only temporarily associated with the membrane. They can be easily removed, allowing them to become involved in cellular communication.

<u>A channel protein is an embedded protein found the cell membrane which provides a hydrophilic passageway for water and small, polar ions</u>. They have a size which excludes all but the specific molecules which move from an area of high concentration to an area with a lower concentration.

To determine if the new membrane protein is a channel protein involved in membrane transport, an experiment could be made by adding more of the proteins to the plasma membrane and measure the rate of the particle movement. If the channel is involved, then the rate will be faster because there are more channels that make the movement faster.

Answer:

Explanation:The investigation is aimed at understanding

1. how molecular size affects movement through a membrane.

Therefore

2.Add more of the proteins to the plasma membrane.

Then measure the rate of the particle movement

Write a 225 word report on why each of the factors (R, K, L, S, C, and P) are important factors needed to determine the amount o
Lostsunrise [7]

Answer:

The R, K, L, S, C, and P factors are -

R - the rainfall erosivity factor,

K - soil erodibility factor

L- the topographic factor derived from slope length

S -the topographic factor derived from slope gradient

C- the cover and management factor

P - the erosion control practice factor

Explanation:

The R, K, L, S, C, and P factors are -  

R - the rainfall erosivity factor,  which depends on geographic location. The greater is the intensity and duration of the rainfall, the higher will bethe erosion potential.  

K - soil erodibility factor,  K signifies the soil loss in tonnes/hectare (tons/acre) for any agricultural land that is cultivated and has a slope length (assumed) of 22.13 meters and slope steepness of 9%. K represents the susceptibility of a soil particle to be easily detached from the surface and carried away by rainfall and runoff. The greater is the value of K , the greater is the erodibility of the soil particles.

L- the topographic factor derived from slope length, It signifies the extent of soil being carried away when slope lengths is greater than an assumed slope length of 22.13 meters. The longer the slope , the higher is the rate of erosion.  

S -the topographic factor derived from slope gradient, It signifies the extent of soil being carried away when slope steepness is greater than an assumed slope steepness of 9%. The steeper the slope , the higher is the rate of erosion.

C- the cover and management factor, It states how effective soil and crop management systems is in terms of preventing soil loss. It is a ratio of soil loss from land under a specific crop and management system to corresponding loss from continuously fallow and tilled land. The higher the C value, the lower is the management process quality to prevent soil erosion

P - the erosion control practice factor,  It represents the after effects of practices pertaining to reduce erosion by reducing the amount and rate of the water runoff. The lower the P value, the better is the effects of practices pertaining to reduce erosion

What factors limit the size of a cell?
vesna_86 [32]

Answer:

Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

Explanation:

I hope this helps you!
