pyruvate kinase is a tetrameric enzyme that can exist as an l (found mostly in liver) or m (found mostly in muscles) form. which of the following statements comparing the l and m forms of pyruvate kinase is true? the m form is more likely to become phosphorylated in the presence of high level of insulin. the l form is more likely to become phosphorylated in the presence of high level of glucagon. the l form is more likely to become phosphorylated in the presence of high level of insulin. the l form is more likely to become phosphorylated under high blood sugar conditions. the m form is more phosphorylated when glucagon levels is high.
Answers
“The l form of pyruvate kinase is more likely to become phosphorylated in the presence of high levels of glucagon” is true, because the l form is more likely to become phosphorylated in the presence of high level of glucagon, option (B) is correct.
Glucagon signals the liver to release glucose into the bloodstream, and phosphorylation of pyruvate kinase in the liver helps to prevent glycolysis and instead promote gluconeogenesis, which is the production of glucose from non-carbohydrate sources.
On the other hand, the m form of pyruvate kinase is more likely to become phosphorylated when glucagon levels are high, which is consistent with the role of glucagon in promoting glycogen breakdown in muscles to release glucose for energy. Option (B) is correct.

Which of the following predicts the most likely ecological problem that would occur if guppies are introduced into new areas to control the mosquito population?The guppies might have no natural predators, which will result in a dramatic increase in the guppy population and an increase in competition for other native species.The guppy population will likely evolve to consume another food source instead of the mosquito larvae.The larvae will evolve a mechanism that will enable them to avoid predation from the guppies.Predators in the area will consume the guppies, requiring the addition of more guppies on a regular basis.
Answers
Introducing guppies to new areas to control the mosquito population may lead to ecological problems, with the most likely issue being the absence of natural predators.
This could result in a dramatic increase in the guppy population, which may outcompete other native species for resources. Without checks on their numbers, guppies can proliferate rapidly, potentially disrupting the local ecosystem. Other scenarios, such as the guppies evolving to consume a different food source or the larvae developing avoidance mechanisms, are less likely to occur in comparison.
Regularly adding more guppies due to predation in the area is also a less likely problem, as the initial absence of predators would enable guppies to establish themselves in the environment.
Therefore, the primary concern with introducing guppies for mosquito control is the potential for an unchecked population growth, leading to increased competition and negative effects on native species.

"methotrexate is a drug that inhibits the production of the nitrogenous base thymine within a cell. would this be an effective drug to treat cancer? if so, what effect on cell division would it have?"
Answers
Methotrexate would be an effective drug to treat cancer as it hinders DNA replication, which is required for cell division.
Cancer is an uncontrolled growth of cells, which occurs through cell division. For a cell to divide and form new cells, it requires a copy of genetic material. This genetical material DNA contains nitrogenous bases..
Methotrexate inhibits Dihydrofolate reductase which is involved in base generation. In absence of bases, DNA replication can not occur and hence cell will not divide. Thus it is an effective drug in controlling cancer.

Answers
Aspergillus fumigatus is a species of Aspergillus that is differentiated from other Aspergillus species by its ability to produce a variety of mycotoxins and its ability to grow at higher temperatures.
It is also known for being the most common cause of aspergillosis, a group of fungal diseases caused by inhalation of Aspergillus spores. Other species of Aspergillus may have different growth patterns, produce different mycotoxins, and have varying levels of virulence, but Aspergillus fumigatus stands out as a particularly significant pathogen.
Aspergillus fumigatus is a species of fungus within the Aspergillus genus. The key differences between A. fumigatus and other Aspergillus species include its unique microscopic characteristics, growth temperature preferences, and potential health effects.
A. fumigatus produces smaller conidiophores and conidia compared to many other Aspergillus species. Additionally, it has a faster growth rate and prefers higher temperatures (optimal growth at 37°C), which makes it more adapted to the human body. This characteristic contributes to its potential to cause aspergillosis, a serious lung infection in immunocompromised individuals, which is less common in other Aspergillus species.

Which biome is overall least altered by human activity world-wide? A. Tropical seasonal forest. B. Tundra C. Tropical rainforests. D. Deserts.
Answers
The biome that is overall least altered by human activity worldwide is b) Tundra.
What is Biome?
Biomes are major ecological areas that are based on the general temperature and climate of the area, including the physical aspects such as the topography of the landscape, the water and soil present, and the type of vegetation. Biomes range from tropical rainforests to arctic tundra, and each biome has a unique set of environmental factors that contribute to the flora and fauna found within that region.
Why Tundra is least altered by human activity world-wide?
Tundra is the one that has been least altered by human activity worldwide because of the following reasons:
Tundra is an ecosystem that is characterized by extremely low temperatures, low precipitation, and short growing seasons. The soil is typically frozen year-round, which makes it difficult for plants to take root, and the harsh climate limits the number of animals that can survive in this environment. Human activity in tundra biome is limited, due to the above-mentioned factors and these regions are typically isolated from human settlements or infrastructure.As a result, tundra biomes are some of the least impacted by human activity worldwide.

What is true about a gene mutation? A. They affect a single gene. B. They cause the entire chromosome to die. C. They are much larger than chromosomal mutations.
Answers
They are much larger than chromosomal mutations. A genetic mutation is a change in DNA sequence of a gene that results in development of new organism. It alters DNA sequence of the gene permanently.
Genetic diversity is crucial for human evolution, which is a long-term process of expansion. Only one person is impacted by a chance genetic mutation. Their offspring inherit the person's genetic mutation. If the mutation increases a person's chance of living or preventing illness, it starts to be handed down through the generations and spread throughout the population. As it is passed from one generation to the next, the mutation changes from a gene variant to a normal gene and becomes a crucial component of the human genome.
