Answer:
A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.
Explanation:
Answer:
8A
Explanation:
I= Q/t, where
I= current (A)
Q= charge (C)
t= time (s)
First convert the time from minutes to seconds.
1 minute= 60 seconds
2 minutes= 2×60= 120 seconds
Using the formula,
I= 960÷120
I= 8A
B. A balanced
Explanation:
In a balanced ecosystem decomposers breakdown dead or decaying organisms and they return nutrients to the soil to be used by plants.
A balanced ecosystem maintains an equilibrium between the biotic component and abiotic component of the system.
- The nutrient cycling between biotic component and abiotic part of the ecosystem is kept going by decomposers.
- Decomposers are organisms that breaks down dead and decaying organisms.
- They release the nutrients trapped in them in the process.
- The nutrient in the soil is in its abiotic state.
- When plants takes up the nutrient, it enters back into the biotic component.
- Decomposers helps to maintain the balance in the ecosystem.
