how do organisms grow?
a) through cell division and production
b) through anaerobic respiration
c) through creation of new organ systems

Explanation:

First Question (about electrical and chemical gradients in active transport)

When two gradients (electrical and chemical) act as opposite forces in active transport, their effects counteract. Opposite forces tend to cancel (negate) each other's influence, not weaken by half, strengthen, or triple. So option C is correct.

Second Question (How do organisms grow?)

Organisms grow mainly via cell division (increasing cell number) and cell growth (production - increasing cell size/function). Anaerobic respiration is for energy in oxygen - limited conditions, not growth. Organisms don't "create new organ systems" as a primary growth mechanism; growth starts at cellular level with division/production. So option A is correct.

Answer:

C) They negate each other.
