How did scientists discover that all living things are made of cells?
Around 1850, Virchow saw cells dividing and added that living cells arise only from other living cells. These ideas led to cell theory, which states that all organisms are made of cells, all life functions occur in cells, and all cells come from other cells.
How did Pasteur’s experiment with the flasks help disprove the idea that living things could just appear or come from nonliving things like water and air?
The end of the revolutionary period of the theory of abiogenesis and biogenesis was after the appearance of Louis Pasteur (1822-1895), a chemist who was very interested in chemical changes that occurred during the fermentation process of wine.
Why are nutrients needed for living things? Describe the difference between living and nonliving things.
all living things need water, and some source of food. The difference between a living and non-living thing is that one need water and other nutrients to keep it alive whereas non living things do not.

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.

Why does natural selection occur more when there is competition for resources?
Answers
Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.
In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.
Competition leads to differential survival and reproductive success among individuals.
Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.
These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.
Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.
Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.
Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

Which of the following statements about feedback regulation of a metabolic pathway is correct?
A) The compound that regulates the pathway acts as a competitive inhibitor or a positive allosteric regulator.
B) The enzyme that is regulated by feedback inhibition is usually the last enzyme in the metabolic pathway.
C) The final product of a metabolic pathway is usually the compound that regulates the pathway.
D) The products of the pathway become the reactants for a different reaction, and thus products are unable to accumulate.
E) Accumulation of the product of the pathway increases further formation of that product.
Answers
Answer:
Correct answer is: B) The final product of a metabolic pathway is usually the compound that regulates the pathway.
Explanation:
Feedback regulation of a metabolic pathway is a mechanism by which the end product of a pathway inhibits an enzyme that catalyzes an early step in the pathway, thus preventing the overaccumulation of the product. This is an example of negative feedback, which maintains homeostasis and optimizes the efficiency of the pathway.
For example, in the synthesis of the amino acid isoleucine from threonine, the final product isoleucine binds to the allosteric site of the first enzyme in the pathway, threonine deaminase, and inhibits its activity. This reduces the rate of the pathway and prevents the excess production of isoleucine.

C. Sea levels
D. Temperatures
Answers
The correct option from the given question is option A) Freshwater is expected to decrease due to climate change.
Explanation:
Climate change refers to the long-term changes in the average weather patterns that have come to define Earth’s local, regional, and global climates. Climate change is primarily due to the increase in atmospheric concentrations of greenhouse gases (GHGs) produced by human activities, such as burning fossil fuels and deforestation.
Climate change has numerous consequences on the planet, including rising temperatures, sea level rise, increased frequency, and severity of extreme weather events, and changes in precipitation patterns, all of which have significant impacts on human societies and ecosystems.
Among the given options, freshwater is expected to decrease due to climate change. Climate change alters precipitation patterns, resulting in more frequent and severe droughts in some regions and increased flooding in others, resulting in water shortages. Higher temperatures and evaporation rates result in drier soils, which reduces water availability. These factors can reduce the amount of freshwater available for human consumption, agriculture, and other purposes.
