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)

Humans are classified into what group of mammals because their developing embryo grows within the mother before a live birth?
Humans belong to the group of mammals known as placental mammals, because the developing embryo grows within the mother before a live birth.
Placental mammals are any of a group of mammals in which the embryo and later the fetus, is nourished in the uterus by an organ called the placenta. The placenta is an organ that attaches the embryo to the uterine wall and is the site of exchange between the mother’s and the fetus’s blood in order to provide nourishment to the developing fetus.
Placental mammals are the most highly evolved group of mammals and include monkeys, apes, and humans. In contrast to other mammals, such as marsupials whose embryos are nourished in the uterus for a short time before being born, placental mammals develop within the mother until they are fully developed. This prolonged period of development in the mother gives the fetus time to fully develop its organs and to grow to a larger size before birth.

What is the hypothesis of Mendel?
The hypothesis of Mendel define the field of genetics by describing, genes, alleles and their pattern of inheritance.
Mendel's hypothesis states that when two parents with different alleles for a trait produce offspring, each offspring will receive one allele from each parent. This law helps to explain why certain traits are inherited, as well as why the ratio of certain traits can be predicted. Additionally, Mendel's hypothesis states that the alleles for a trait separate during the formation of gametes and randomly unite at fertilization.
Thus, Mendel proposed various law on the basis of hypothesis and proved them, the law include, Law of dominance, Law of segregation, and Law of independent assortment. These Law greatly define the filed of classical genetics.

Achondroplasia (dwarfism) is caused by a dominant gene. A woman and a man both with dwarfism marry. If homozygous achondroplasia results in the death of embryos, then the expected ratio of normal to affected children will be
The expected ratio of normal to affected children will depend on the genetic background of the parents. If both parents have achondroplasia, which is a dominant gene, then each of their children has a 50% chance of inheriting the condition.
In this case, the expected ratio of normal to affected children would be 1:1. However, if one parent is heterozygous (carries one copy of the gene) and the other is homozygous (carries two copies of the gene), then the expected ratio of normal to affected children would be 3:1.
This is because the heterozygous parent has a 50% chance of passing on the achondroplasia gene and the homozygous parent has a 100% chance of passing on the achondroplasia gene.

How does smoking weaken damage the respiratory system?
The smoking or act of inhaling smoke can damage the respiratory system by reducing the surface area for the exchange of the gases and can lead to cancer as well.
Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. It can also cause irritation of the trachea (windpipe) and larynx (voice box). Inhaled tobacco smoke moves from the mouth through the upper airway, ultimately reaching the alveoli.
As the smoke moves more deeply into the respiratory tract, it can cause inflammation and damage to the cilia, tiny hairs that play an essential role in the function of the respiratory system. Smoking can also increase the production of phlegm and mucus, leading to an increased risk of respiratory infections. It can also damage the cilia that help to clear unwanted particles from our lungs over time. Cigarette smoke can also contain high levels of carcinogens, which can lead to lung cancer.

An organism that has two different alleles of a given gene has a(n) heterozygous genotype. aneuploid dizygous heteromorphic heterozygous homozygous
Heterozygous genotypes are characterized by two different alleles of a particular gene. These alleles can be inherited from different parents or from the same parent, and this type of genotype is also known as a dizygous genotype.
An example of this is eye color; if an individual has one allele for blue eyes and one allele for brown eyes, they would have a heterozygous genotype. This type of genotype is important for producing genetic diversity, allowing for adaptations that can be beneficial to a species. It is also important to note that having a heterozygous genotype does not guarantee that the individual will express the traits of both alleles; rather, the individual will usually express the trait of the dominant allele.

How would cyanide poisoning affect the rest of the ETC and proton gradient across the inner mitochondrial membrane?
After the cyanide poisoning the proton gradient will be reduced. Moreover, it will lead to the stopping of the electron transport chain (ETC). Because it prevents the complex IV from transporting electrons, cyanide functions as a poison.
Most of the electron transport chain will abruptly slow down and cease if complex IV cannot transmit electrons. Protons won't be pumped out of the matrix and into the intermembrane space if electrons aren't traveling along the transport chain. The gradient will deteriorate as the protons already in the intermembrane space move down their gradient and into the matrix because they won't be replaced. Thus, this will cause the intermembrane space's pH to decrease.
