Answers:

1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.

2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.

3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.

Step-by-step explanation:

Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.

Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.

Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.

Describe trilateration. Provide an example.
kaheart [24]
Trilateration Measures Distance, Not Angles
Using a simple two-dimensional example, let's imagine we have three GPS satellites each with a known position in space. ... This means that the distance could be anywhere on that circle. But this time, we have two known distances from two satellites.

Which of the following is continually passed from one enzyme to the next during the Electron Transport Chain?
AVprozaik [17]

The correct answer is electrons.  

Electron transport chain refers to an array of complexes, which mediates electrons from electron donors to electron acceptors through redox reactions, and combines the transfer of electrons with the transfer of protons through a membrane.  

This produces an electrochemical proton gradient, which instigates the production of ATP. The ultimate electron acceptor in the electron transport chain is oxygen in aerobic respiration and sulfate in anaerobic respiration.
