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

Messenger RNA carries a(n) ___________ of the DNA’s instructions out of the nucleus to the ___________.
Nitella [24]


messenger RNA  (mRNA) carries a transcript (copy) of the DNA's instructions out of the nucleus  to the cytoplasm where it attaches to a ribosome.

transfer RNA (tRNA) begins to read (translate) the information on the attached mRNA and corresponding to this information, fetches the appropriate amino acids from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are linked into a chain or polymer forming the primary structure of the desired protein.

A geochemical cycle is the pathway that involves the movement of elements or substances in the Earth's surface and the crust.  I believe the answer are hydrologic, heat, and rock. These are the three main geochemical cycles of the Earth and are responsible of continuously removing and adding materials here on Earth.
