That might help ^
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
Natural selection only occurs when there is a superiority within a species set. If there is no genetic variation, no single animal is any better than the next, making the presence of superiority impossible and survival left up to chance. In this case it would be considered genetic continuity.
The correct answers are <span>by adding greenhouse gases to the atmosphere by using natural resources, by polluting the land, water, and air, by creating landfills and by introducing invasive species to the environment.
Adding greenhouse gases to the atmosphere contributes to the rise of the global temperature and climate change which leads to the rise in sea level, and extreme weather conditions.
By polluting the land water and air and creating landfills humans are destroying not only the habitat of many plants, animals, and other organisms but also for themselves.
Overexploitation of the natural resources also leads to the destruction of habitat and collapse of ecosystems.
The introduction of invasive species often leads to disruption of the food chain of an ecosystem since the invasive species might be more efficient in this habitat and suppress the native organisms.
