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.

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.

Answer:

Please find the description of the steps involved in DNA replication below. The terms listed in the question are written in BOLD.

Explanation:

DNA replication is the process by which DNA molecule is duplicated in the genome to produce two identical copies. DNA replication, which must occur prior to any cell division, involves the following steps:

- An enzyme called DNA HELICASE unwinds the double strand of DNA into a Y-shaped replication fork.

- Another enzyme called DNA POLYMERASE attaches to the single strand of DNA to add nucleotides to the growing DNA molecule.

- An enzyme called DNA PRIMASE adds a short nucleotide sequence called PRIMER, which serves as foundation for DNA polymerase to act upon.

- The DNA polymerase adds nucleotides based on complementary base pairing rule i.e. A-T, G-C.

Answer: theories, experiments, research basics, scientific laws, and fictions

Explanation:

Scientific theories are the explanation for a scientific phenomenon. It is verified by experimental trials. These can be obtained in text books.

Experiments are the methodologies which are followed to verify a scientific fact or theory. These can also be available in text books.

Research basics includes the steps that are to be followed while conducting a research and ethics oriented to research. These can also be included in text books.

Scientific laws are the description about a scientific phenomenon without explaining how did the phenomenon occurred. These can also be included in the text books.

Fictions are the stories or self constructed narrations which can be or cannot be based on true incidences. These can be available in text books.

Hypothesis is a supposed explanation of a particular phenomenon and it can be proved by using scientific methodology. It cannot be found in the text books as it is the original piece of research to be conducted and can be available as a part of research synopsis.

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.

Therefore, The animal Darwin is describing is a tortoise. In the reading, there are quotes that imply that it is a tortoise such as:

Answer:

The correct answer is - The population would decrease.

Explanation:

natural selection is a change of an organism that helps in surviving in an environment change that is unfavorable to it.  If a population of pepper moths is relocated a lush, green rainforest ecosystem, it the environment could kill off the peppered moths due to their evolutionary characteristics will make them stand out to predators which decreases their population or kill them due to their diet.  

Answer:

The Peppered Moth Population Will Decrease or be Completely Wiped Out.

Explanation:

The change would almost inevitably result in the extinction of peppered moths. They would become extinct, whether they were light or dark in color. Because of their color, they would be unable to blend in with their new lush environment. They would also suffer because their diets are different and contain certain animals than those available in the lush forest.

Answer:

Soil erosion.

Explanation:

No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.

Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.

Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.

Answer:

he Axolotl, or the Ambystoma mexicanum, is located in the class amphibia and in the family of Ambystomatidae. They are a critically endangered species that resides in Mexico. More specifically, the walking fish is native only to  Lake Xochimilco and Lake Chalco in central Mexico. These unique fish have many attributes that makes it different from other amphibians and fish found in lakes.

Axolotls are 9 inch "walking fish" that have the amazing ability to regenerate limbs. They can regenerate any lost limb, including their head. This salamander has a soft bodies with small "horns" sprouting from the sides of their head. These horns are actually gills, meaning that instead of having their gills located inside of their pharynx the frills are set on the sides of their head.  

The spots commonly found on an axolotl are not unusual, it's part of an extremely advanced system called the lateral line system. This system consists of electroreceptive ampullary organs and mechanoreceptive neuromasts organized into lines across the creature's body. This system is connected to the nervous system, and it allows the axolotl to sense movement and vibrations in the water.
