There is a small amount of NAD+ made by a cell. If oxygen is not present, pyruvate becomes the final electron acceptor thus allowing for the recycling of NAD+.
QUESTION: EXPLAIN how using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+.
Answers
Claim: Using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+.
What are the evidence and reasoning?Evidence: During anaerobic respiration, the breakdown of glucose begins with glycolysis. In this process, glucose is broken down into two pyruvate molecules, which also generate ATP and NADH.
Under anaerobic conditions, pyruvate becomes the final electron acceptor instead of oxygen. Pyruvate is then converted to lactate or ethanol and CO2, which regenerates NAD+ from NADH.
Reasoning: In the absence of oxygen, cells rely on anaerobic respiration to generate energy. During glycolysis, glucose is broken down into pyruvate, which generates a net of two ATP molecules and two NADH molecules. In order for glycolysis to continue, NADH must be recycled back to NAD+.
However, without oxygen, the electron transport chain cannot occur, and the NADH cannot be oxidized. Instead, pyruvate acts as an alternative electron acceptor, which is converted to lactate or ethanol and CO2. This reaction allows NADH to transfer its electrons to pyruvate, regenerating NAD+ in the process. As a result, glycolysis can continue to generate ATP, and the cell can survive under anaerobic conditions.

Describe the life cycle of a pine tree.
Answers
Answer:
The life cycle of a pine tree, like most coniferous trees, goes through several stages:
Seed Germination: The life cycle of a pine tree begins with the germination of a pine seed, stored in a cone. When favorable conditions, such as moisture and warmth, are present, the seed germinates, and a new pine seedling emerges.
Seedling Stage: The germinated seed develops into a seedling, with a single stem or shoot with a few small, needle-like leaves called cotyledons. The seedling relies on stored nutrients within the seed until it develops its own root system for nutrient uptake.
Sapling Stage: During this stage, the pine tree develops more branches and foliage. The sapling continues to grow in height and expands its root system to access water and nutrients from the soil.
Maturation and Reproduction: As the pine tree reaches maturity, it enters the reproductive stage. This typically occurs when the tree is around 10 to 20 years old, but it varies depending on the pine species. The pine tree produces cones, which contain the reproductive structures. Male cones release pollen, which is carried by wind to female cones for fertilization. Fertilized female cones develop seeds within them.
Cone Development and Seed Dispersal: The fertilized female cones undergo maturation and development. This process can take several months to years, depending on the species. Once mature, the cones open, releasing the seeds, which are dispersed by wind or animals.
Senescence and Regeneration: After seed dispersal, the pine tree enters a phase of senescence, or decline. This stage can span many years or even decades, depending on the lifespan of the pine species. The tree's growth slows, and its overall health deteriorates. Eventually, the tree dies, either naturally or due to environmental factors, making way for new seedlings to grow in the surrounding area and continue the cycle.
Explanation:
Many scientists oppose offshore drilling. Since the 1970s there have been several devastating oil spills as a result of oil exploration and drilling: Ixtoc, Exxon Valdez and, most recently, the Deepwater Horizon blowout off the coast of Louisiana. Ecosystems may survive, and some may eventually recover from such oil spills. But the overall effects are far reaching and long lasting. Scientists still see the effects of the toxic spill on the crab populations in surrounding wetlands. Others argue that the effects of not drilling are just as harmful. But, rather than ecosystems, it harms the economy. If we can drill our way out of poverty, then we owe it to ourselves to do so. In addition to this, it is put forth that reliance on foreign oil leads to the entrenchment of hostile regimes in oil rich regions. Extensive research along the Gulf Shore has uncovered a rise in cancer rates directly linked to consumption of seafood contaminated by the Deepwater Horizon blowout. How are the pro-drilling and anti-drilling arguments affected by this discovery?
A It weakens the anti-drilling argument and weakens the pro-drilling argument
B It is impossible to say how this evidence will impact either argument.
C It supports the anti-drilling argument.

For this discussion post, I read the article “A creator of ‘CRISPR babies’ nears release from prison, where does embryo editing stand?
This article explained how biophysicist He Jiankui, who used the genome editor CRISPR to create the world's first genetically engineered babies, may be released from prison this week.
His November 2018 announcement about gene editing was well received. Still, Fyodor Urnov sees no circumstance that would justify efforts to modify babies genetically. Urnov supports using CRISPR to fix disease-causing mutations after birth. The work has proceeded with little notice, and oversight measures to stop rogue experiments like He's have stalled. A study showed how CRISPR could get rid of a newly fertilized egg of an extra copy of a chromosome. This problem can lead to Down syndrome and other medical conditions. The initial concerns about designer babies centered on CRISPR's sloppiness. But a study of CRISPR-altered human embryos found 16% had these "unintended editing outcomes" at the targeted DNA, and genetic screening of edited IVF embryos might not catch these errors. Stem cell researcher Dietrich Egli hopes to find a way to start and stop CRISPR at the embryo's single-cell stage. In a preprint posted on bioRxiv on 10 March, Egli's group demonstrated a strategy for trisomy, an errant third chromosome, by targeting an extra paternal or maternal chromosome copy with a CRISPR cut at or near its centromere.
If CRISPR does not correct the trisomy in all of the cells in an early embryo, a natural "rescue mechanism" might eliminate the abnormal cells. However, there are still multiple obstacles to overcome. Researchers are trying to use CRISPR to edit human embryos but need help beyond science. Editing the DNA of egg or sperm precursor cells may avoid some of these hurdles, improving the odds of getting it right. Orwig's team is exploring a different route to creating edited sperm stem cells by reprogramming adult human cells into a stem cell state and trying to coax them partly down the pathway that produces sperm. However, reprogrammed adult cells only survive when placed into newborn animals, which is unrealistic for humans. Scientists say the increased awareness of CRISPR's shortcomings has underscored the recklessness of transplanting edited embryos with today's technology. Still, some scientists are openly advocating for the practice.
find something interesting and 1-2 questions about the summary
Answers
One interesting aspect of the article is the discussion around using CRISPR to edit disease-causing mutations after birth, rather than in embryos.
What is the authenticity if genetically modifying babies ?Fyodor Urnov supports this approach and believes that there is no circumstance that would justify modifying babies genetically. This raises the question of whether there is a moral or ethical line that should not be crossed when it comes to genetic modification of humans, even if it is done to prevent or treat disease.
Another interesting point is the potential use of CRISPR to edit the DNA of egg or sperm precursor cells to avoid some of the hurdles of editing embryos. This raises the question of how this approach would be implemented and regulated, as it involves altering the genetic material of potential future offspring before they are even conceived.
Overall, the article highlights the ongoing debate and ethical considerations around the use of CRISPR for genetic modification in humans, as well as the need for continued research and oversight to ensure that any such use is safe and ethical.

Photosynthesis and cellular respiration are two close related and complementary processes. Photosynthesis produces organic molecules and releases oxygen, which are used during cellular respiration to produce water, ATP, and CO₂.
What are photosynthesis and cellular respiration?
Photosynthesis is a process plant cells go through when absorbing sunlight.
During photosynthesis, light energy and inorganic compounds are used to produce organic compounds -glucose- and release oxygen.
It occurs in chloroplasts and involves two stages: light-dependent and light-independent reactions.
• During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions. It occurs in the thylakoid membrane in the electron transporter chain.
• The light-independent reaction occurs in the Calvin cycle in the stroma. During this stage, carbon from CO2 is fixated, and sugar molecules are synthesized
Cellular respiration is the process through which cells use organic compounds to produce energy.
Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
Aerobic Respiration1. Occurs in the presence of free oxygen.
2. Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
3. Respiration occurs in the mitochondria.
4. Takes place in two steps or stages: Krebs cycle and electron transporter chain.
5. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
Anaerobic Respiration1. Occurs in the absence of free oxygen
2. Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
3. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
4. Lactic fermentation produces lactic acid and 2 ATP
5. Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
6. The whole anaerobic process occurs outside the mitochondria.
Photosynthesis is complementary to cellular respiration.

Scenario: Researchers posted ads in the newspaper to recruit participants for their study of a new treatment for agoraphobia (the fear of open places). 87 people responded to the ad, but only 60 of those actually reported being agoraphobics. Of the sixty, 20 were randomly placed in a condition (NEW) in which they received the new treatment. It was explained to the NEW participants that the treatment they would be receiving was promising but new, so they would be monitored carefully to watch for any undesirable side effects. Twenty other participants were assigned to a condition (OLD) in which they received an older, more traditional form of treatment. These participants were told that they were not receiving the new treatment but an older treatment that had been around for awhile, so the chances of side effects were minimal. Finally, 20 other participants were randomly assigned to a group (NO) that received no therapy. After six months of treatment, researchers found that the participants in the NEW condition were exhibiting 64% fewer symptoms of agoraphobia than before they started the treatment. Participants in the OLD condition were exhibiting 42% fewer symptoms, and participants who did not receive therapy exhibited 22% fewer symptoms than six months ago. Researchers were pleased with the results, concluding in an article they were writing that a new treatment had been found that will be more successful with agoraphobics than previous treatments.

To determine whether the tests are effective vs if nothing is done to address the problem, the "none" is compared to the tests. To compare with the "new," the "old" is present. It would be inefficient and necessary to eliminate the "new" if it is neither better nor worse than the old.

A person with agoraphobia could be afraid of riding public transportation.A tragic childhood event, such losing a parent or experiencing sexual assault. suffering a stressful incident, such as a death in the family, a divorce, . a history of mental diseases including depression, bulimia, or anorexia nervosa. misuse of drugs or alcohol.
