The appearance of living systems on Earth from non-living molecules is called <span>chemical evolution.</span>
Answer:
The correct answer is B-typically grow slower than in pure culture
Explanation:
In nature, microbes experience lots of challenges like challenges to get space, to live, to get food, to adapt to the changing environment, to get protection from their pathogens and predators, etc. So these all challenges affects the growth rate of microbes.
In pure culture only one type of bacteria is grown on a nutrient-rich media and a steady environment is given to them to grow. In pure culture, there are no predators and competitors for microbes.
So all this provide favorable condition for a microbe to flourish in a pure culture so the growth of an organism in pure culture is higher than in nature. So the correct answer is B.
I believe that C would be the best answer to this question.
I really hope that this helps you out
Transport
The protein is working to transport substances across the membrane.
Answer:
The neurons are unable to repolarize.
Explanation:
The cell membrane potential remain negative at the resting membrane potential. The potassium channels maintains the negative voltage inside the cell and makes the cell stable at resting membrane potential.
The scorpion agitoxin affects the potassium channels, the depolarize cell remains in the depolarize state because potassium channels are inhibited. The cells are unable to repolarize as the potassium channels are unable to enter in the cells.
