Cooler and even the place in which it is is going to be more humid.
Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.
<h3 /><h3>What is tundra ecosystem?</h3>
Tundra ecosystems are treeless areas found in the Arctic and on mountain peaks where the climate is cold and windy and rainfall is scarce.
Much of the year, tundra lands are covered in snow, but summer brings bursts of wildflowers.
Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time.
Thus, the correct ecosystem for the given condition is tundra.

Answer:
B. Premature stop codon mutation
Explanation:
Answer:
The correct order, from fastest to slowest, for the passage of molecules and ions through the cell membrane is oxygen, sodium ions, glucose (option D).
Explanation:
The plasma membrane is a lipid bilayer, with glycoproteins and membrane proteins, which constitutes a semi-permeable barrier to the passage of substances into and out of the cell.
The speed with which a substance can pass through the membrane depends on its chemical properties -hydrophilic substances pass through with greater difficulty than lipophilic ones- requiring in some cases specialized transport mechanisms. The different rates with which a substance passes depends on this.
- <em>Oxygen (O₂) </em><em>passes through simple diffusion, depending on a concentration gradient. It's the molecule that passes through the membrane the fastest.
</em>
- <em>In second place, there would be the </em><em>Na⁺ ions</em><em> -charged atoms- that cross the membrane by facilitated diffusion, through specific ionic channels.
</em>
- <em>The </em><em>glucose</em><em> molecule, being larger, requires the use of transport proteins, being its passage through the membrane slower with respect to oxygen or sodium.</em>
Undoubtedly, molecular weight and affinity for the plasma membrane are determining factors for the passage of molecules through the lipid bilayer.
