C. To make a punnet square, make a square and make a line through from bottom to top, and left to right. Then on top, put one of each letter (FF) on top of each square. Do the same with the other (ff). Then put each letter in the box that matches where the letters are. You will get Ff for each. Tell me if you need more help. Punnet squares can be confusing at first.
Answer:
The answer is the first option. The trailing edge is composed of many filopodia containing tight parallel bundles. These filopodia push trailing edge away from the location it was previously occupying.
Explanation:
Cells migrating in tissues exhibit both filopodia and lamellipodia. These thin protrusive extensions are ideal for exploring and penetrating tissue spaces. They are also well suited for intercalating between cells, such as during the migration of leukocytes across endothelial layers.
Therefore the answer is the first option.
