Explain the mechanisms for movement of materials across cellular membranes anatomy
trapecia [35]
There are 2 types of transport mechanisms that involve the movement of materials across the cellular membrane:

1. Passive Transport Mechanisms which is the movement of materials that does not require energy. Instead the movement relies on the permeability of the cell. Under this are three kinds of passive transport mechanisms:

a. Simple Diffusion: 
- the movement of materials from a region of higher concentration to lower concentration. No external energy is necessary for the movement. The materials supply the energy themselves. 

b. Facilitated Diffusion:
- This differs from simple diffusion because the movement is facilitated by proteins that make up the structure of the membrane. The proteins include channel proteins that allow ions and smaller molecules to cross the membrane. The other protein are the carrier proteins, which bind to materials like sugar molecules and move it across the membrane.  

c. Osmosis:
- This is the diffusion of water across the membrane. Osmosis moves water from regions where there are more water molecules of water per volume to regions where there are less water molecules per volume.  

2. Active transport on the other hand is a movement mechanism that requires energy. It uses the energy to send materials against the direction it is coming from through simple diffusion. This mechanism is used in a way to keep unwanted ions or other materials out of the cell.

Which of the following is not a contributing factor to ecosystem stability species, genetic,ecosystem, or abiotic diversity.
insens350 [35]

Answer:

Ecosystem.

Explanation:

Ecosystem is not a contributing factor to ecosystem stability whereas, species, genetic, and abiotic diversity are the factors that contributes in the stability of an ecosystem. The diversity of species greatly affected the ecosystem stability if more species are present in he ecosystem. The abiotic factors also plays an important role in the stability of an ecosystem because these abiotic factors causes changes in the ecosystem environmental conditions.
