"U"-shaped, with peaks at the low and high extremes of beak size; disruptive selection
Answer:
it's "True"
Mauna Loa is the most active volcano on Earth
Answer:
an increase in the temperature will increase the average kinetic energy of the molecules which causes the molecules to move faster
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.

<h2>Regulate of Environmental</h2>
Explanation:
- The motivator based administrative methodology progresses in the direction of forestalling ecological issues by giving promptings to urge contaminating substances to diminish contamination.
- An advantage of the motivator based methodology is that it energizes the production of imaginative and financially savvy techniques for <em>contamination control. </em>
- Administrative methodologies require government offices to limit or direct the exercises of controlled gatherings utilizing terms and conditions inside statutory and administrative instruments, <em>working grants, licenses, endorsements or codes of training. </em>
- <em>Command and control causes administrators to benefit as much as possible from whatever hardware they have - individuals, data, material, and, regularly generally significant of all, time. </em>
- Particles have assisted with securing nature, they have three weaknesses.
- <em>They give no motivating force to going past the cutoff points they set.
</em>
- They offer restricted adaptability on where and how to lessen contamination.
- <em>They regularly have politically-spurred escape clauses.</em>
