The most powerful approach to isolating a single mutant from a population of billions is positive selection.
Answer:
The correct answer will be- true (assuming the student is asking the true or false)
Explanation:
Biodiversity refers to the diversity of the biological world. The biological world is composed of the living organisms and their associated concepts.
The biodiversity represents the variety of organisms and species in an ecosystem, variety in the ecosystems and the genes which contribute to the variation in the organisms along with controlling the traits of organisms. The biodiversity is the major factor which has maintained the natural sustainability on Earth.
Thus, true is the correct answer.
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.
