If a cell becomes freely permeable to sodium ions (na ) and is not regulated, what will be the resulting membrane potential?
Since their are more sodium ions outside the cell at test, if a cell becomes freely permeable to sodium ions and is not regulated, the membrane potential will be positive.
What is membrane potential?The membrane potential is the potential difference across a neuronal membrane due to the difference in the concentration gradient of oppositely charged ions.
At rest, the inside of the membrane is negative while outside is positive due to more sodium ions being outside the cell.
Therefore, if a cell becomes freely permeable to sodium ions and is not regulated, the membrane potential will be positive.

Scientists have studied the return of plant life on Mount St. Helens ever since the volcano erupted in
1980. Wildflowers began colonizing the area, followed by shrubs and small trees. Scientists predict
that it will likely take hundreds of years before the area returns to a forest dominated by fir and
hemlock trees. These changes are an example of:
a. humans degrading an ecosystem by removing wildflowers
b. the loss of genetic variation in a plant species
C. the growth of a forest through ecological succession
d. the biological evolution of wildflowers, shrubs, and trees
Answer:
C.
The ecosystem there will definitely go through ecological succession by which the structure of the flora there will evolve over time into forests.

Which of the following statements about energy and trophic levels is not true? a. the amount of available energy decreases at each higher trophic level. b. the energy conversion efficiency decreases at higher trophic levels. c. the net production of energy is higher at lower trophic levels. d. none of the above please select the best answer from the choices provided a b c d
All statements are true about the energy and trophic levels. So, the correct option is D. None of the above.
What are trophic levels?Trophic levels are the levels of energy transfer from lower to higher levels.
There are five levels of trophic level.
The lower level contains autotrophs or producers. And the uppermost level contains big animals or tertiary consumers.
The energy level decreases on going to the higher levels because some amount of energy always lapses as entropy.
Thus, the correct option is D.

The mutual interdependence that characterizes oligopoly arises because.
We can confirm that the mutual interdependence that characterizes oligopoly arises because the output for a given market is being generated by a small group of companies.
What is oligopoly?Oligopoly is when the market for a given product is controlled by only a few of the companies that create said product. This situation can have benefits as well as drawbacks. A benefit would be increased product variation, providing more choices for consumers, while a drawback would be a lack of competition to keep prices low.
Therefore, we can confirm that the mutual interdependence that characterizes oligopoly arises because the output for a given market is being generated by a small group of companies.

In a marine food web the total biomass of algae far outweighs the total biomass of all the killer whales. Why?
Answer:
because there is more potential food energy in the algae but not in the killer whales because nothing eats the killer whales
Because there is a greater potential for food energy in the algae than there is in the killer whales, who have no natural predators because nothing consumes them.
What is biomass?The biomass of an ecosystem is what determines its structure. The energy contained in living creatures is referred to as their biomass. Autotrophs are the producers in a food chain and are responsible for converting the energy from the sun into biomass. Each successive trophic level results in a loss of biomass. Lower trophic levels almost always contain a greater quantity of biomass than higher ones do.
In the vast majority of ecosystems, the producer level contains both the highest energy level and the greatest amount of biomass. Because of this, there is a greater potential for food energy in the algae than there is in the killer whales. This is also due to the fact that the killer whales do not have any natural predators.

Could melanin granules be moved by dynein and kinesin along an actin microfilament?.
We can confirm that melanin granules could in fact not be moved by dynein and kinesin along an actin microfilament.
Why can these substances not be moved along a microfilament?This has to do with the fact that these proteins are specific to microtubules, and therefore are not able to move along microfilaments. This is why the dynein and kinesin motor proteins would not be able to transport the granules along microfilaments.
Therefore, we can confirm that melanin granules could in fact not be moved by dynein and kinesin along an actin microfilament.
