PEP + ADP → Pyruvate + ATP ∆G = -14.8 kcal/mol
ATP + H2O → ADP + Pi ∆G = -7.3 kcal/mol
Glutamic acid + NH3 → Glutamine ∆G = +3.4 kcal/mol
Which reactions can be coupled?
Answers
Reactions can be coupled if the products of one reaction are reactants in the other reaction, and if the overall ∆G of the coupled reactions is negative. Therefore, reaction 3 (Glutamic acid + NH3 → Glutamine) is the non-spontaneous reaction among the given reactions.
We can see that in this instance, the first two processes involve the interconversion of ADP and ATP and have negative G values. As a result, they are both exergonic, or processes that release energy.
These two reactions can therefore be coupled because the first reaction's energy discharge can be used to fuel the second reaction.
The third process, on the other hand, produces glutamine from glutamic acid and ammonia and has a positive G value. This indicates that it is an endergonic process, which uses up energy.
This reaction therefore cannot be coupled immediately to either of the first two reactions. Therefore the reaction 3 is correct.

A young man leaped from his hotel room to avoid burning to death in a fire. If he landed on his heels, what bone was likely to fracture? Unfortunately for the young man, a 240-pound fireman ran by and stepped heavily on the distal part of a young man’s foot (not the toes). What bones now could be broken?
Answers
The young man in question who leaped from the hotel room onto his heels and was then stepped on by a fireman is likely to have fractured 11 bones in each of his feet.
The feet of most individuals are comprised of 7 tarsal bones, 5 metatarsals, and 14 phalanges (2 for the "big toe" and 3 for all others). The only group with names are that of the tarsal bones, which are:
CalcaneusTalusCuboidNavicularMedial, middle, and lateral cuneiformsThe question states that the young man landed on his heels. This would mean that the bone that absorbed the impact of the fall is the calcaneus, which comprises the heel of the foot.
The young man's foot is then stepped on by a 240-pound fireman. Assuming that all of the bones stepped on are fractured, the young man will have fractures in each of the tarsal bones with exception of the talus which comprises the ankle as well as the metatarsal bones.
The question states that the fireman steps on the distal part of the man's foot, but not the toes. This area of the foot is comprised of the tarsal bones mentioned above, and the metatarsals. This is why all of the these bones listed above except the talus are likely fractured.

Spontaneous generation is the myth that organisms could originate without the need to have descent from similar organisms (i.e., created spontaneously from the dust). This belief stated that organisms could arise from nonliving material. Louis Pasteur conducted experiments in order to show that this belief was false and thus confirm the theory of biogenesis, which states living organisms can be only generated by the reproduction of similar living organisms. Pasteur showed that microorganisms could not be developed in isolated sterilized tubes, but they could be developed in open tubes, thereby showing that reproduction (biogenesis) is the only source of living organisms.

Which of the following would be an example of an R-selected species?
Answers
An example of an R-selected species would be one that produces a large number of progeny with small size. So, the correct option is C.
R-selected species are characterized by their reproductive strategy, which focuses on producing a large number of offspring with relatively small size. These species prioritize quantity over quality when it comes to offspring production.
Option ''Large number of progeny with small size'' represents an example of an R-selected species. These species typically have a high reproductive rate and invest minimal resources in individual offspring. By producing a large number of progeny, they increase the chances of survival and successful reproduction in unpredictable or unstable environments.
In contrast, options A) Small number of progeny with small size and B) Small number of progeny with large size represent strategies more commonly associated with K-selected species. K-selected species prioritize quality over quantity, producing fewer offspring but providing them with greater parental investment and resources, resulting in larger size and higher survival rates.Option D) Large number of progeny with large size is less commonly observed in nature and does not align with the reproductive strategy of either R-selected or K-selected species.Therefore, the correct option is C.

Explanation:
The fluid moved from the glass to Emma's mouth due to reduced pressure in the mouth during the sucking process.
When the water is in the glass and the straw is placed in the fluid,there is no flow of fluid up the straw because the Atmospheric pressure outside the glass maintains an equal pressure on the surface of the glass.When Emma sucks in the water with the straw,there is increased volume in the mouth that will create a low pressure zone in the mouth.This in turn will make the higher atmospheric pressure outside the glass force the liquid up the straw to reach Emma's mouth.

Give an example of a situation where gene expression without regulation could potentially harm an organism.
Answers
An example of a situation where gene expression without regulation could potentially harm an organism is in the development of cancer.
Cancer is often caused by mutations in genes that control cell growth and division. These mutations can cause these genes to be expressed in an unregulated manner, leading to uncontrolled cell growth and the formation of tumors.
Without regulation of gene expression, the cell can continue to divide and grow out of control, eventually leading to the development of cancer. Gene regulation mechanisms, such as DNA methylation, histone modification, and microRNA, are critical in preventing the uncontrolled expression of genes that can lead to cancer.
Thus, the regulation of gene expression is essential for maintaining normal cellular function and preventing the development of diseases like cancer.

Anaerobic fermentation is a metabolic process done by bacteria and eukaryotes in the absence of air to convert carbohydrates into the products like gases, alcohol, and acids.
What are examples of anaerobic fermentation?In the absence of oxygen, bacteria and eukaryotes carry out anaerobic fermentation, a metabolic process that produces gases, alcohol, and acids from carbohydrates.
Various compounds, including acetic acid, are produced in industries using this fermentation. While there is no oxygen present during fermentation, energy can still be generated from the glucose. Yeast cells undergo fermentation, while bacteria and mammalian muscle cells also undergo some sort of fermentation.
Energy is produced from glucose through two different types of cellular respiration: aerobic fermentation and anaerobic fermentation. Anaerobic fermentation can occur without oxygen while aerobic fermentation does. The three primary types of fermentation are lactic acid fermentation, ethanol fermentation, and hydrogen and oxygen.

Question: How does the amount of global carbon emissions
affect the occurrence of global extreme weather catastrophes?
Background research :
The sun radiates light energy to Earth which then radiates it back as heat. Some heat is trapped by our atmosphere, helping to warm our planet. However, due to human activities, greenhouse gasses (carbon dioxide, methane, nitrous oxides, etc.) have been increasing and thickening our atmosphere, leading to global temperatures rising rapidly. The main cause is burning fossil fuels, especially coal, for electricity. Rising heat in the oceans are causing ocean-based storms (hurricanes, typhoons, cyclones) to be stronger.
Answers
The amount of global carbon emissions has a direct impact on the occurrence of global extreme weather catastrophes. As more and more greenhouse gases are released into the atmosphere, they thicken and trap more heat, which leads to a rapid increase in global temperatures.
This increase in temperature has a significant effect on the oceans, causing ocean-based storms like hurricanes, typhoons, and cyclones to be stronger and more frequent. To understand this phenomenon, we can use the CER (Claim-Evidence-Reasoning) framework.
The claim is that the amount of global carbon emissions affects the occurrence of extreme weather catastrophes. The evidence is that greenhouse gases like carbon dioxide, methane, and nitrous oxides have been thickening our atmosphere, leading to a rise in global temperatures. This rise in temperature is causing stronger and more frequent ocean-based storms.
The reasoning behind this is that when the Earth's atmosphere thickens with greenhouse gases, it traps more heat and leads to a rise in global temperatures. This rise in temperature has a direct impact on the oceans, causing ocean-based storms to become stronger and more frequent. Therefore, reducing global carbon emissions is essential to mitigate the occurrence of global extreme weather catastrophes.

Proteins and sugar are present in the sample. Hence the correct options are b and c.
Iodine test = yellow: The iodine test is used to detect the presence of starch. When iodine reacts with starch, it forms a characteristic blue-black color. In this case, since the result is yellow, it suggests the absence of starch in the sample. Biuret test = blue: The bluret test, also known as the Biuret test, is used to identify the presence of proteins.
Benedict's test = blue: Benedict's test is used to detect the presence of reducing sugars, such as glucose and fructose. When a reducing sugar reacts with Benedict's reagent, it forms a color change from blue to green, yellow, orange, or red, depending on the concentration of the sugar. In this case, the blue result indicates the presence of reducing sugars in the sample.
