I am unfamiliar with English units. What is the relationship between pounds-mass and pounds-force?

If, say, you were to calculate a force needed to accelerate a tank or something and the weight (pounds-force) was known, you would simply divide by the gravity acceleration (32.2 ft/s^2) to know the pounds-mass?

Did I do this right, I need it ALL to be correct, it is regarding inductive and deductive reasoning
A) If all adult female birds lay eggs, then this female chick will lay eggs if raised to maturity.
Deductive reasoning
B) If all known species of birds are egg-laying, then the next bird species to be discovered will be egg-laying too.
Inductive reasoning
C) If all known enzymes are made into protein, and I discover a new enzyme, then it, too, will be made of protein.
Inductive reasoning
D) If the amounts of protein X are increased under stress, then I should be able to increase the amount of protein X in these frogs by subjecting them to stressful conditions
Deductive reasoning
E) If this species mates in April, then I should be able to observe more mating on April 10 than on June 10
Deductive reasoning

I've noticed that when I was much younger, 6th graders looked like high schoolers and now even myself as a Senior and classes below me kids are very short and look about the size of 1st graders. Are we going in cycles of height? I don't even look my age at all, it's weird.

I just asked a question about Algebra before Geometry. Now, I want to know if it is really necessary to take algebra before Biology. Again... my 10th grader is being told that Algebra is a prerequisite for Biology.
