If an object is having a constant positive acceleration, what can we assume about the forces on it?

If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.

the answer would be 3

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
