From the nernst potential given, the mg2+ ion is at a higher concentration outside the cell.
What is nernst potential?
The potential across the cell membrane that exactly opposes net diffusion of a particular ion through the membrane.
The nernst potential of an ion is calculated as follows;
[tex]E = \frac{RT}{zF} ln[\frac{ion \ outside \ cell}{ion \ inside \ cell} ][/tex]
The given nernst potential of mg2+ ion is +30 mv = +0.03 V, (positive volt).
A positive log can only be obtained when the numerator (ion outside cell) is greater than the denominator (ion inside cell).
Thus, from the information given, the mg2+ ion is at a higher concentration outside the cell.

Conclusions 2. Two new species of plants were introduced into an area that was low in available nitrogen compounds in the soil. One formed nodules and one did not. Which species would you expect to grow more robustly? Explain. (4 points) Answer here..
Answer:
The one forming nodules would grow better.
Because it may be a leguminous plant.
Rhizobium bacteria will reside in the root nodules and fix atmospheric nitrogen for these plants by symbiotic relation.
They will fix nitrogen in the soil and increase soil nutrient quality.

3. What do you think most public water is used for?
Answer:
The Earth might seem like it has abundant water, but in fact less than 1 percent is available for human use. The rest is either salt water found in oceans, fresh water frozen in the polar ice caps, or too inaccessible for practical usage. While population and demand on freshwater resources are increasing, supply will always remain constant. And although it's true that the water cycle continuously returns water to Earth, it is not always returned to the same place, or in the same quantity and quality.
n this experiment the bag contains a hypertonic solution (sucrose), while the beaker only contains water. If you leave the bag inside of the beaker for approximately 45 minutes; the movement of water will occur from the ________ to the _________.
The water will move from beaker to the bag of sucrose due to concentration difference.
In which direction the water will move?The movement of water will occur from the beaker to the bag because the concentration of water is lower in the bag and higher in the beaker. So due to the process of diffusion, the water will move from the higher concentration region to lower concentration region.
So we can conclude that the water will move from beaker to the bag of sucrose due to concentration difference.

The water in vegetables evaporates over time causing the vegetables to wilt. Why do grocery stores spray water on their vegetables?.
Answer: For aesthetic reasons and to charge extra.
Explanation: Shoppers are more drawn to vegetables with water because they look more hydrated and “fresher”. Vegetables absorb moisture, so they will weigh more, therefore shops can charge more.

which type of drosophila probably changed the least over time?
The type of Drosophila that probably changed the least over time is the Drosophila melanogaster.
What do you mean by Drosophila?A Drosophila may be defined as a fruit fly that serves as one of the most important model organisms in the field of biological sciences due to its large chromosomes, high reproduction rate, and various varieties.
As compared to Drosophila willistoni, Drosophila equinoxialis, Drosophila equinoxialis caribbensis, etc. Drosophila melanogaster changed very least over time after analyzing its evolutionary pathway.
It is because it may consist of a large chromosome but a simple arrangement of genes, its well-specified segment polarity genes, pair-rule genes, and maternal effect genes.
Apart from this, it may also be because of less natural selection applied to Drosophila melanogaster.
Therefore, the type of Drosophila that probably changed the least over time is the Drosophila melanogaster.

Life system: cyanobacteria begin photosynthesis and produce oxygen. Earth system: free oxygen reacts with rocks (axidation), resulting in increased rates of weathering for soil
production. Life system: land plants evolve and take root in terrestrial soil.
O Life system: cyanobacteria begin photosynthesis and produce oxygen. Earth system: free oxygen reacts with all available dissolved iron in the ocean. Life system: mass extinction
event of anaerobic organisms occurs from buildup of oxygen in the ocean.
• Earth system: oxygen moves from the ocean to the atmosphere through gas exchange. Earth system: free oxygen reacts with incoming solar radiation to form ozone. Earth system:
ozone collects in the stratosphere to form the protective ozone layer.
O Earth system: molten Earth forms into layers based on density and pull of gravity. Earth system: Earth cooled, and the water vapor in the atmosphere condensed and created the
oceans. Life system: cyanobacteria evolved.
The cyanobacteria were already there without the oxygen, so that rules out A, and a lot of prokaryotes were anaerobic, so that rules out Finally, Photosynthesis does not require oxygen. Instead, Oxygen is a waste product of it.
What is photosynthesis?Photosynthesis is a process that occurs in the chloroplast organelle of plant cells. The typical light reaction of photosynthesis takes place inside the thylakoid membrane of the chloroplast. The chief reactants such as water and carbon dioxide participate in the reaction. The water gets oxidized in the reaction to release oxygen as a product. The carbon dioxide gets reduced.
