Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

The correct answers are:
- Decrease in rainfall in the Mojave desert;
The decrease in rainfall can be devastating to a lake's waters and biodiversity. The decrease in rain usually causes bigger loss of water through evaporation than water coming in the lake, so over time it will dry out, or just small pieces of it will remain.
- Decrease in runoff that flows into Mojave Lake;
If the amount of water that comes into the lake decreases, it can be fatal to it, and in a very short period of time, since the lake will be losing more water than it gets in.
- Increase in blocked streams that flow into Mojave Lake;
Naturally, streams can be blocked and redirected, so if this happens, we have the same situation from before, where the water income is smaller than the water loss of the lake.
Yes it is a secondary consumer because it is a parasite than lives off of organic molecules made by consumers at any level.
Answer:
The Highlands are older as evidenced by their crater density.
Explanation:
The answer is;
Both plant and animal cells have a nucleus, where DNA replication takes place.
Cellular respiration does not take place in the ER but in the mitochondria present in both plants and animals.
Only plant cells have cell walls, Animals cells have only the cell membrane
Plants cells have a cell vacuole while animals cells do not.
