Sodium and potassium ions can diffuse across the plasma membranes of all cells because of the presence of what type of channel?

Biology
1 answer:
MrMuchimi4 years ago
5 0

The correct answer is option d, that is, leak channels.  

The cell membrane comprises protein channels known as leak channels, which permits sodium and potassium ions to leak down their concentration gradients. The membranes of the cell are significantly more permeable to potassium ions in comparison to the sodium ions, due to the presence of more K+ leak channels than Na+ leaks channels.

why are protists discussed in groups such as animal-like plant-like or fungus-like protists? Please Help!
kipiarov [429]
They're separated based on how they get their energy. Plant-like protists get their energy from the sun-- they're producers. Animal-like protists feed off of producers-- they're consumers. Fungus-like protists are decomposers because they get their energy from dead organisms.

malfutka [58]

Answer:

1. The size and growth rate of the human population has changed in the past 200 years because reproduction rates have increased due to the large number of people in the world.  2. Human population has grown exponentially over the past century. It has done so largely by producing large amounts of food, and learning how to control disease. Ten thousand years ago, when humans first invented agriculture, there were maybe one million humans on the planet.
