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.

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.

For this assignment, you will develop a model to describe the cycling of matter and the flow of energy
among living and nonliving parts of an ecosystem. This project includes both an individual and a group
part. On your own, you will research an organism that is assigned to you. In your group, you will combine
your organism with the organisms researched by other students to create a food web. Together, you will
write two short paragraphs explaining how energy and matter move through the food web.
Answer:
All I can tell you is when energy is moves through the food web it gets divided by 10
plant energy =1 0,000 (example)
that plant gets eaten by a small animal
small animal's energy gained from the plant = 1,000
a large animal then eats the smaller one
large animal's energy gained from the small animal = 100
Explanation:
I am sorry you will have to write your two short paragraphs on your own.
I don't want you to get in trouble for plagiarism.

The rabies virus is capable of entering the brain with the blood of a victim of the bite of an infected animal. Propose a mechanism for this to happen.
This is clear demonstration that neurons are not like other cells and that they need a unique environment to thrive and function properly. It also protects neurons from blood-borne proteins, cells and toxic factors.
what causes blue whales to grow so large
Answer:
Stronger upwelling created the right conditions for baleen whale prey, such as krill and forage fish, to become concentrated in dense patches along coastlines. Whales that fed on these prey resources could forage efficiently and predictably, allowing them to grow larger.

why argon is called inert element?
Answer:
Helium neon and Argon are called inert gases are noble gas because they have complete its duplet as well as Octate. and no other element like Helium neon and Argon complete its octate and duplete. in the 18th period all element are inert. Which gas does not exist in air?
Explanation:
Answer:
The outermost (valence) shell of argon has eight electrons, making it exceedingly stable and, thus, chemically inert.
In an example of pleiotropic genes, the flower color gene studied by Mendel affected ________ trait(s).
Answer:
two traits ,
Explanation:
In an example of pleiotropic genes, the flower color gene studied by Mendel affected a single trait.
Pleiotropy refers to a phenomenon where a single gene influences multiple, seemingly unrelated traits or characteristics in an organism. However, in this specific case of Mendel's flower color gene, it affected only one trait, which is the color of the flower.
Genes are the basic factors of inheritance. They are found in the DNA of all living organisms. They are responsible for transmitting genetic information from one generation to the next and play a crucial role in determining an organism's traits and characteristics.

The passage of blood from the atria to the ventricles is regulated by which valves?.
Answer:
I believe it is the tricuspid valve
Explanation:
Answer:
Tricuspid Valve
Explanation:
The tricuspid valve regulates blood flow between the right atrium and right ventricle. The pulmonary valve controls blood flow from the right ventricle into the pulmonary arteries, which carry blood to your lungs to pick up oxygen.
in your field experiment to study the gene flow between the lizard populations what type of evidence will support that gene flow has occurred?
The change in allele and genotypic frequencies in a population is evidence of gene flow.
What is gene flow?The term gene flow makes reference to the interchange of genetic material between individuals of two or more populations.
The gene flow generates a change in the allele and genotypic frequencies in the individuals of a population in equilibrium.
The gene flow may be due to migration and this phenomenon must be mediated by reproduction.

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.

Explain how the VIH virus uses specific structures to enter the cell
Answer:
When HIV infects a cell, it first attaches to and fuses with the host cell. Then the virus uses the host cell's machinery to convert the viral RNA into DNA and replicate itself. The new copies of HIV then leave the host cell and move on to infect other cells.
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.
