Please help! I have no clue what I'm doing.

A net force is acting on an object causing it to accelerate at 6 m/s^2. Determine the resulting acceleration if (a) the force is halved; (b) the mass is halved; (c) both the force and the mass are halved.​

True or false: (a) the strings of little red dots represent carbohydrates. (b) the model is called a bilayer because there are two main types of molecules present, lipids and proteins. (c) the many black lines represent amino acid tails. (d) this model shows membrane transport. (e) the blue ovals are hydrophobic. (f) the blue ovals represent phospholipid heads.
