1 is the answer because it’s talking about chemical
When an electron<span> moves from </span>one atom<span> to </span>another<span>, </span>both atoms become<span> ions.</span>
Active transport requires energy when moving molecules against a concentration agent. It requires for specific membrane transport proteins. Only a certain type of protein can move a certain type of substance.
The three main types of Active Transport are:
1) Sodium-Potassium Pump
2) Endocytosis
<span>3) Exocytosis </span>
The procedures that can be used to perform water erosion laboratory practicals are:
- The use of detachment
- Transportation
- Deposition.
<h3>What is Water Erosion?</h3>
This refers to the biological process where rock particles are broken down into smaller particles and how they are removed by water.
Hence, we can see that in a laboratory experiment, one would need different apparatus such as:
- Pitchers
- Bottles
- Soil
- Water, etc.
This would be used to test the loss of water as it is put into the soil from the set of bottles to see how much the water is retained.
