Answer:
Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>
A doctor can use a 2D image model to show where the break is.
When a patient breaks a leg (the break could be as a result of fracture or bone dislocation), the doctor needs to scan the patient in order to determine the exact location of the break and the extent of the injury.
The gamma camera, x-ray machine and PET scanners are some of the devices that can be used to scan a bone.
Each of these devices uses 2D image technology to show the result of the scan.
So, a model that can be used by a doctor to determine the location of the break is 2D image.
