In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.

This paragraph attempts to explain the rain shadow effect, but it gets some of the facts wrong. Identify the inaccurate statemen
EleoNora [17]

The inaccurate statements are:

- Warm, moist air goes up the mountain on its leeward side, where its water content condenses to precipitate as rain or snow;

- This side is called the windward side and, compared with the leeward side, receives hardly any rainfall;

In the description, the windward and the leeward sides of the mountain are mistaken, or rather have switched positions.

The windward side is the side where the warm, moist air where the water condensates and results in rainfall or snow. Thus this is the side of the mountain that is wetter and is covered with denser vegetation.

The leeward side is the side that doesn't receive warm and moist air, and the amount of precipitation is usually very low. This makes the leeward side very dry in most cases, and very often it is the reason for the formation of arid and semi-arid areas.

Answer:

The K-selection reproductive strategy maximizes the survival of offspring by producing <u>few offspring with high levels of parental care.</u>

<u></u>

Explanation:

Depending on how many offsprings members of a species produce and how much care they invest in them, we can divide species into two categories:

  • r-organisms. These organisms produce many offspring, sometimes even thousands of them. They live in unpredictable, dangerous environments with a lot of predators. This is why most of their young die. It's important for at least some of them to survive so that they can continue reproducing and keep the species alive. The parents don't invest much care into their young. Some examples of these species are mice, rabbits, weeds, and bacteria.
  • K-organisms. These organisms are the opposite of r-organisms. They live in more stable environments, which guarantees that their lifespan will be longer. This is why it's not necessary for them to produce many offspring. Parents invest a lot more care into their young. Some examples of these species are humans, elephants, horses, and primates.

Based on this information, we can conclude that the K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
