The total productive areas in which a population, a person, or a product competes are tallied as ecological footprint. It gauges the ecological resources needed by a particular population or product to produce the natural resources it consumes (such as plant-based food and fiber products, livestock and fish products, timber and other forest products, and space for urban infrastructure), as well as to absorb its waste, particularly carbon emissions.
<h3>What is ecological reserve/deficit?</h3>
An ecological deficit happens when a population's ecological footprint exceeds the biocapacity of the space that population has access to. If a country has a national ecological deficit, it is either importing biocapacity through commerce, selling off its ecological resources, or releasing carbon dioxide waste into the sky. When a region's biocapacity surpasses its population's ecological footprint, an ecological reserve is created.

Answer:
They are nonlobed, simple leaves and are attached oppositely on the branch.
Explanation:
A dichotomous key is a tool you use in biology to know the identity of things in nature such as trees,flowers, fish or even rocks. This key has choices that follow each other in a progressive manner, where one choice led to the other until you identify the item.In this case, to identify Dogwood, you follow the below steps;
1b. Broad leaf = Step 2
2b. Simple leaf = Step 7
7a. Leaf bases attached opposite each other on branch = Step 8
8b. Leaves not lobed = Step 9
9b. Leaves not heart shaped = Dogwood
The key is (1b,2b,7a,8b,9b)
Answer:
3) Temperature
4) gill covering opening and closing per minute
5)as temperature rises, the rate of gill covering opening and closing per minute increase until the temperature reaches 27℃ where the rate decreases
Explanation:
4) you can adjust and control the temperature in an experiment
5) you can't control the gill opening and closing rate
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.
