Explanation:
RNA polymerase II is inhibited by certain drugs and toxins. One well-known inhibitor of RNA polymerase II is a toxin called α-amanitin, which is found in some species of poisonous mushrooms, such as the death cap mushroom (Amanita phalloides).
α-Amanitin functions by binding to RNA polymerase II and preventing it from transcribing messenger RNA (mRNA). This inhibition of mRNA synthesis disrupts the process of protein production in eukaryotic cells, which can ultimately lead to cell death and various toxic effects in the affected organism.
It's important to note that inhibition of RNA polymerase II is highly toxic and can be fatal if ingested. Poisoning from mushrooms containing α-amanitin can result in severe liver and kidney damage. If there is a suspicion of mushroom poisoning, immediate medical attention is crucial.
Residents praise community leaders for saving land for a new park.
Limiting the use of public land caused business to have less customers.
Less land pollution has led to lower spreading of diseases.
Answer:
Explanation:
The statement that describes a positive political outcome of how land can be used is: "Residents praise community leaders for saving land for a new park."
This statement highlights a positive outcome in which community leaders make decisions to preserve land for a new park. By doing so, they are meeting the recreational needs of the residents and providing a public space for enjoyment and relaxation. This decision is praised by the residents, indicating that it is seen as a valuable use of the land and a positive political outcome.
The other options provided do not describe positive political outcomes related to land use:
- "When common lands are protected, land degradation slowly disappears." While this statement highlights a positive environmental outcome, it does not specifically address the political aspect of land use.
- "Limiting the use of public land caused business to have fewer customers." This statement suggests a negative outcome where limiting the use of public land negatively affects businesses and their customer base.
- "Less land pollution has led to lower spreading of diseases." This statement also highlights a positive environmental outcome but does not focus on the political aspect of land use.
In summary, the statement "Residents praise community leaders for saving land for a new park" describes a positive political outcome of how land can be used, as it highlights the satisfaction and appreciation of residents towards the decision made by community leaders to preserve land for a park.
Answer:
The correct answer is b. He determined that DNA contains four nitrogenous bases.
Explanation:
Levene was an American biochemist who studied the structure of DNA in the early 1900s and in 1920 he found that DNA consists of four nitrogenous bases that are Adenine, Guanine, Thymine, Cytosine.
He also found deoxyribose sugar and phosphate group and said that nucleotide is the basic unit of DNA which contains a ribose sugar with attached nitrogenous base and phosphate group.
He also concludes that an equal amount of adenine, guanine, thymine, and cytosine makes the DNA which is now known as tetranucleotide hypothesis. So the correct answer is b. He determined that DNA contains four nitrogenous bases.
The Americans resorted to energy and gas-saving measures to cope with the embargo and the high price of oil. The competition posed by non-OPEC members also contributed to the drop in oil prices and this affected the Arab economy who also took up austerity approaches to address the matter. The prices of oil later stabilized in the 1980s.
Answer: the answer is A. Increased its dependency on foreign oil
Explanation: just took test.
b. Sexual reproduction produces larger numbers of offspring in less time.
c. Sexual reproduction produces offspring that have greater genetic variety and durable zygotes that can help green algae species survive unfavorable conditions.
d. Sexual reproduction produces multicellular algae instead of unicellular algae. Multicellular algae are better able to survive harsh conditions.
facilitated transport
ionic pump mechanisms
i'd say during facilitated diffusion this happens but it's not an option so i'd have to say facilitated transport then, i hope i'm right and i hope this helps!! :)
