A sperm count is diluted 1:20 and 50 sperms are counted in 2 large squares of the Neubauer counting chamber. The sperm count in mLs is;

c. would be the answer : )

explanation:

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

weathering is the answer.

we would need to see the picture to answer it
