Why did different food preservation methods develop in different regions?
Why were beer and wine consumed so commonly?
Why did bread become such a common food source?
How did the work of Pasteur impact food safety?
Why would soldiers have consumed a drink made of diluted vinegar?
All of the questions that doesn't have a "?" I'm not going to answer, cause this is like kinda hard.
Review Questions:
You need to know what biotechnology means to solve the first problem.
Is an umbrella term that covers a broad spectrum of tools and techniques, ranging from fermentation to plant and animal breeding, cell and tissue culture, antibiotic production and genetic engineering. The traits of every organism are encoded in its genetic material which is organized into individual units called genes. Genetic modification is achieved by changing the code or organization of the genetic material of an organism.
1) Recombinant antifreeze proteins that extend the shelf life of frozen dairy products and fruits, fermented whey that is high in acids to preserve cheese and rosmarinic acid produced from rosemary plant cell cultures as an oxidant.
2) Are rich in probiotic bacteria so by consuming fermented foods you are increasing the health of your gut microbiome and digestive system
3) As bread dough is mixed and kneaded, air bubbles are trapped and dispersed throughout the dough. The starches and sugars in the flour, turning them into alcohol and carbon dioxide gas. This gas network of air bubbles, causing the bread to rise.
Critical Thinking Questions:
1) Different ones developed in different regions because the much of there food on there climate. People in cold climates could use the natural resources.
2) Why were beer and wine consumed so commonly? I don't know the answer
3) Bread has been an important staple food product to many cultures. Stone mechanisms were used for smashing and grinding cereals to remove the inedible outer husks.
4) Pasteur completed the first successful test on April 20, 1862, patenting the method we now know as pasteurization, which was soon applied to beer, juice, eggs, and (most famously) milk.
5) Diluted vinegar has been used as a strengthening and energizing tonic. Roman soldiers called this refreshing drink “posca”, and used it regularly as did the Japanese samurai.
I feel my typing is faster now, but all questions are easy enough for me cause its like 50 points lol :)
Mark me brainliest!!! Much apperciated.
Recombinant antifreeze proteins and fermentation are the methods of food preservation that are examples of biotechnology.
Pasteurization is a process in which pathogenic microorganisms are destroyed or killed in certain foods and beverages by providing specific amount of heat.
The main advantages of Fermentation is that it helps to break down nutrients that is present in food, make it easier to digest than unfermented food substances.
The cheese making process consist of six important steps i.e. acidification, coagulation, separating curds, salting, shaping, and ripening.
Yeast uses the sugars and oxygen that is present in dough in order to produce more yeast cells which releases more carbon dioxide gas. The carbon dioxide cause rise in the dough which gives the bread a light and spongy texture.
Different food preservation methods develop in different regions of the world because the environment as well as different types of pathogens are present which needs different method for its removal.

What protein pigment and area of the chloroplast gets its electrons excited by sunlight? What occurs in the stroma?
Answer:
chlorophyll
The chlorophyll obtains its electrons from water (H2O), producing O2 as a by-product. During the electron-transport process, H+ is pumped across the thylakoid membrane, and the resulting electrochemical proton gradient drives the synthesis of ATP in the stroma.
What factors affect the likelihood a species will migrate from the mainland to an island?
Answer:
The factors that might affect the likelihood a species will migrate from the mainland to an island are the distance to the mainland and the island´s size.
Explanation:
Ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could inhabit an island.
Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance to the mainland and the island´s size.
At the same time, these factors affect immigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those located farther from the mainland. This is the effect of distance.
The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.
In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.
the effect on shrubs growing in one area if they are treated with a compound that blocks electron flow through the electron transport chains of chloroplasts. Provide reasoning to justify your prediction.
Answer:
Blocking electron flow prevents the generation of a proton (H+) gradient required for ATP synthesis, and this ATP is in turn exploited by photosynthetic cells to produce organic molecules. In consequence, the blockage of this process would have critical implications for the survival and growth of the shrubs.
Explanation:
In plant photosynthetic reactions, photons from sunlight excite (energize) electrons from chlorophyll molecules located in the thylakoid sacs of the chloroplast. Subsequently, the high-energy electrons move across the electron transport chain that pumps protons (H+) to generate a gradient across the thylakoid membrane. This proton gradient is then exploited by plant cells to synthesize ATP, which is in turn used to create energy-rich organic molecules (e.g., sugar). In consequence, blockage of the electron flow would be critical for the survival and growth of the shrubs.

Jose fears a bioterrorism attack with the Ebola virus but refuses to get a flu shot, even though he is more at risk of dying from the
flu. Jose has what perception
towards risk?
a. optimism bias
b. degree of controltion
c. catastrophe
d. Instant gratification
optimism bias. jose thinks he's immune to the flu, even though he is afraid of diseases in general.
What is Optimism Bias?
The optimism bias is essentially a mistaken belief that our chances of experiencing negative events are lower and our chances of experiencing positive events are higher than those of our peers.
This phenomenon was initially described by Weinstein in 1980, who found that the majority of college students believed that their chances of developing a drinking problem or getting divorced were lower than their peers.
The optimism bias doesn’t mean that we have an overly sunny outlook on our own lives. It can also lead to poor decision-making, which can sometimes have disastrous results.
Therefore, optimism bias. jose thinks he's immune to the flu, even though he is afraid of diseases in general.

1. In your own words, what does it mean for a cell to be
specialized ?
Answer:
For a cell to be specialized it means that, even though the cells are similar, they differ in shape, size, function, and have a different role in our body. Every cell adapts to the function it has in the body.
Explanation:
Differentiation refers to the serial steps that a cell goes through to become mature. As the cell develops, it begins to show its own purpose and role in the human body, a process known as differentiation.

Where do the calories in your food come from?
Answer: Calories are the amount of energy released when your body breaks down (digests and absorbs) food.
Explanation:
The more calories a food has, the more energy it can provide to your body. When you eat more calories than you need, your body stores the extra calories as body fat. Even a fat-free food can have a lot of calories

What is evolution?Evolution is defined as a change in the genetic composition of a population over successive generations. Let’s arrange the theories given by the following in chronological order-
Greek and Rome – The evolutionary theory was proposed for the first time some 2000 years back by Anaximander.
Erasmus Darwin brought his “The law of organic life” in between years 1794-1796.
Lamarck Mallus first presented his theory of Inheritance of Acquired Characteristics in 1801.
Darwin published his work “Origin of species” in 1859.
The Greeks developed, with Miletus, a primitive theory, indicating a possible relationship between man and animals. Erasmus Darwin and Malthus (the first was Charles's grandfather), developed theories that grounded the naturalistic idea. Lamarck brings erroneous concepts, but they are fundamental for Darwin, finally, to develop his Origin of the Species.

A. an electrical force
B. an external force
C. a magnetic force
D. a frictional force
10 POINTSSSSSS
Answer:
B. an external force
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
Hence, a secured object in an orbiting spacecraft remains at rest unless acted upon by an external force.
