Based on the movie( Food Inc), what are examples of policies that have been proposed as ways of dealing with social
changes resulting from new technologies, such as genetically engineered plants and animals.
Answer:
Food, Inc. Summary
If you aren’t completely familiar with what it is, Food, Inc was created by documentary filmmaker Robert Kenner and narrated by Eric Schlosser (Fast Food Nation), and also features commentary from Michael Pollan (The Omnivore’s Dilemma).
It lifts the veil on how the nation’s food industry has been consumed by corporations and how that impacts the farms where our food comes from, the supermarkets where we buy our food, and the restaurants where we eat that food. It tackles the FDA, food safety, food production, large-scale animal processing plants, and other food matters. If you are at all concerned or curious about the state of food supply in America, you should watch Food, Inc.
The Key Takeaways from the Movie
Supermarkets and Corn
The tomatoes you buy in the grocery store are picked when green and then ripened with ethylene gas
The food industry doesn’t want you to know the truth about what you are eating because if you did you might not eat it—it is a world deliberately hidden from us
Most people have no idea where their food comes from (do you?)
The fact that people need to write a book (and a blog!) telling people where their food comes from shows how far removed we are
The average grocery store has 47,000 products which makes it look like there is a large variety of choices—but it is an illusion—there are only a handful of corporations (like Monsanto, Tyson, and Perdue for example) and a few major crops involved
So much of the processed food is just clever rearrangements of corn (here are just a few examples of the additives that are derived from corn: cellulose, saccharin, polydextrose, xanthan gum, maltodextrin, and my favorite—ha ha ha—high fructose corn syrup)
30% of our land base in the US is used to grow corn because thanks to government policy farmers are paid to overproduce this easy-to-store crop
Farmers are producing so much corn that food scientists had to come up with uses for it—just like some of the additives listed above
Food scientists have also spent a lot of time reengineering our foods—so they last longer on grocery store shelves and don’t get stale
At the supermarket, candy, chips, and soda are all cheaper than produce
A double-cheeseburger from McDonald’s is 99 cents and you can’t even get a head of broccoli for that price
Those snack calories are cheaper because the commodity crops like corn, wheat, and soybeans are heavily subsidized
You start feeding corn to cows, E. Coli evolves and a certain mutation occurs which is very a harmful bacteria
Animals at factory farms stand ankle deep in their manure all day long so if one cow has E. Coli others can get it too
At a slaughterhouse their hides are caked with manure and if you are slaughtering 400 cows per hour how do you keep it from spreading?
So these harmful new strains of e Coli, that didn’t use to be in the world, are now a problem
E. Coli is even in spinach and apple juice because of the runoff from factory farms
It doesn’t help that the Chief of Staff for the USDA was a former lobbyist for the beef industry
Regulatory agencies are being controlled by the very companies they are supposed to be scrutinizing
There has always been food poisoning, but food is not getting safer it is becoming more contaminated because with the bigger factories it spreads the problem far and wide
There are only 13 slaughterhouses for the majority of beef in all the US
Ground beef from the grocery store has thousands of different cows mixed up in it so the chance of one of those cows in your meat having a disease is increased
After eating hamburger contaminated with E. Coli 0157:H7 a woman’s 2-year-old son went from a perfectly healthy boy to being dead in 12 days
In the 90’s some industrial meat factories were tested for E. Coli 0157:H7 and if they failed they were supposed to be shut down—but there was not enough authority to close the contaminated plants
Some companies are now using a hamburger meat filler cleansed with ammonia hydroxide to help kill E. Coli (mmm…that sounds tasty)
What are the conclusion from Mendelian experiment?
Mendel gathered his data for tens of thousands of plants before coming to the conclusion that the traits might be divided into expressed and latent features. These traits were described by him as being dominant and recessive, respectively. In a hybridization, dominant features are those that are passed on unaltered.
The three laws of dominance, independent assortment, and segregation serve as a summary of all the findings of Mendel's experiment. He proposed that each gene be passed down to the organisms twice, once from each parent. In their gametes, organisms only share one copy of each gene. In his opinion, traits are discretely inherited from each parent, one at a time.

Why do whales need oxygen?
Whales need oxygen for respiration processes because they do not have gills, and whales are unable to breathe oxygen that is dissolved in water.
The lack of gills, which prevent whales from breathing oxygen dissolved in water, is the most obvious distinction between whales and other fish. Instead, they have lungs, which means that whenever they want to breathe air, they have to come to the surface.
They can stay underwater for hours at a time because they have a very efficient respiratory system that allows their lungs to get the most out of each breath. To put things in perspective, when we are at rest, humans breathe about 12 to 20 times per minute, but they only take in 5% of the oxygen in a single breath. This is in contrast to a whale, which can absorb up to 90% of the oxygen it breathes. This indicates that a whale takes in significantly more oxygen in a single breath than a human does.

What are some evidences that support evolution?
some evidences that support evolution are: anatomy, molecular biology, biogeography, fossils, & direct observation. Genes, which are passed from parent to kid during reproduction, express themselves in these traits.
Evolution is the gradual change in the hereditary characteristics of biological populations over many generations. Genetic recombination and mutation are the usual causes of variation within a population. Genetic drift and natural selection, two evolutionary processes that might lead to particular traits becoming more or less dominant in a population, are likely to occur in this variation. This is how evolution works. Heritable traits emerge over multiple generations in response to shifting evolutionary factors that determine whether a trait is prevalent or rare within a population.

if a cell contained three pairs of homologoues (n=3, 2n=6) how many configurations are possible?
Twice the number of chromosomes in a haploid cell (n).
How many chromosomal combinations are feasible in the gametes of a 2n 6 cell?The number of potential chromosomal pairings in gametes is 2n (two to the ‘n’ power, where ‘n’ is the number of chromosomes in the haploid set). So, for 2n = 4, n = 2, and gamete number = 22 = 4, the answer is 4. Furthermore, for 2n = 6, n = 3, and gamete number = 23, the answer is 8.
As a result, an organism with cells 2n=6 is diploid and contains 6 chromosomes in total. In other words, this creature contains three chromosomal pairs. We will use the formula nCr = n! / r! * (n – r)! to compute combinations, where n represents the total number of things and r indicates the number of items picked at a time.

Capillary action, which allows plant sap to flow through a tree, is the result of cohesion between water molecules. True False
Capillary action happens in light of the fact that water is tacky, on account of the powers of attachment (water particles like to remain nearby) and bond (water atoms are drawn in and stick to different substances).
The development of water particles in the plant body is because of the cement powers between the water atoms and surfaces of the root and stems. The durable powers present between the water particles keep them intact and back off their transportation.
Since water particles like to remain together (attachment) and like to adhere to the walls of the containers of cellulose (bond), they ascend the cylinders as far as possible from the roots to the leaves. Water then, at that point, dissipates from the leaves, assisting with drawing up additional water from the roots. This interaction is called hairlike activity.

"What are the benefits and potential risks of using hot and cold compresses, and when is it appropriate to use each type?"
Theobroma cacao (cacao) is the tree that produces seeds that are turned into chocolate. These trees provide many poor people in the tropics with some cash income. However, these farmers face many obstacles to production of their crop, including temperature and rainfall changes caused by atmospheric CO2 increases, and many diseases and pests. Analysis of the cacao genome showed that there is some (but not a lot) of genetic variation in the 10 major varieties. Which of the following strategies would be most useful in the long term in reducing pressures faced by cacao farmers? Select one:
A. Fertilize the trees in closely spaced areas and add fungicides and pesticides to eliminate pests.
B. Plant more trees in the temperate zone.
C. Plant trees farther apart so that disease transmission rates from one tree to the next will be lower.
D. Crossbreed cacao strains that produce high-quality cacao beans and ones resistant to a disease. Clear my choice
Answer:
B. Plant more trees in the temperate zone.
Explanation:
The presence of abundant cabondioxide (CO2) in the atmosphere is as result of a decrease in plants populations.
plants makes use of CO2 in photosynthesis a process in which green plants manufacture their food Abundance of trees helps to clear the environment from excess CO2 through their utilization leading to a fresh and enabling environment.
Hence their is need to plant more trees in temperate and avoid deforestation of trees to enable plant make of CO2 and reduced the adverse effect of its excess in the environment.
Where is the most ATP produced in cellular respiration ?
The majority of ATP created during cellular respiration is used in the electron transport chain (oxidative phosphorylation).
Cellular respiration is the mechanism by which glucose molecules are broken down into [tex]CO_2[/tex] and [tex]H_2O[/tex] to provide energy from Adenosine Triphosphate (ATP). Additionally, cellular respiration often occurs in an organism's cells by turning the metabolic energy contained in foods into adenosine triphosphate. Additionally, it occurs in three steps, which are the TCA cycle, electron transport, and glycolysis (Oxidative phosphorylation). As a result, the stage of aerobic cellular respiration that produces the most ATPs is called oxidative phosphorylation.
Normally, ATP releases energy by dismantling any weak phosphate cells that may be present. The energy that is released as the phosphate cell disintegrates is then put to use. ADP is created after ATP.

describe how the respiratory areas maintain a normal breathing pattern
The respiratory system is responsible for maintaining a normal breathing pattern by bringing oxygen into the body and removing carbon dioxide. This process is controlled by the brainstem.
How to describe the respiration?The brainstem sends signals to the muscles of respiration, including the diaphragm and the intercostal muscles. The diaphragm is the main muscle used for breathing and contracts during inhalation, causing the lungs to expand and fill with air.
The intercostal muscles, located between the ribs, also contract during inhalation to lift the ribcage and increase the volume of the thoracic cavity. During exhalation, the diaphragm and intercostal muscles relax, and the lungs deflate, pushing air out of the body. The rate and depth of breathing are also regulated by a complex network of nerve cells in the brainstem that respond to changes in blood oxygen and carbon dioxide levels, as well as to other physiological and psychological factors.
