Ver todo en esta sección
El vínculo entre la energía y el cambio climático es muy fuerte. De hecho, ha sido el altísimo consumo de energías fósiles lo que ha provocado el calentamiento del clima que ya sufrimos y que seguiremos experimentando en las próximas décadas.
Desde el inicio de la era industrial, el consumo de energía proveniente de los combustibles fósiles -carbón, petróleo y gas natural- ha ido en aumento. La sociedad, tal y como la conocemos hasta ahora, está basada en estas fuentes de energía y en ellas hemos basado nuestra economía. Pero la quema de los combustibles fósiles es la responsable de la producción de los gases de efecto invernadero, causantes del calentamiento global.
Important steps in sequencing pure proteins include all of these except: a. Determining the amino acids on the ends of the smaller peptides b. Determining the isoionic pH of the protein c. Determining the amino acids on the ends of the protein d. Breaking the protein into smaller peptides e. Determining the amino acid composition
Answer:
b. Determining the isoionic pH of the protein
Explanation:
The sequencing of pure proteins is nothing more than the analysis of the amino acids present in isolated proteins. This analysis is composed by the study of the sequence that the amino acids assume within the protein, the amino acids present in the extremities and the constitution of each one of these amino acids. In summary, we can state that protein sequencing refers to the constitution of these proteins. In this case, the isotonic pH of these proteins is not relevant information.

What is mean by photosynthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunligh, so we eat the plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the reen pigment found in the chlorookasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Answer:
true it consumes some ATP as well as producing it
true it produces ATP that can be directly used by cells
true it does not directly require oxygen to operate
false it produces more ATP than any of the other respiration reactions
Glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.
What is ATP?ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. It is a byproduct of the photophosphorylation, cellular respiration, and fermentation processes and serves as the primary energy currency of the cell.
Glycolysis is defined as a chain of events that convert glucose into two pyruvate molecules, which have three carbons each. Glycolysis is a cytoplasmic process that breaks glucose down into two molecules with three carbons apiece and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.
Thus, glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

Which of the following would ATP NOT be used for as energy?
A. Osmosis
B. Healing a cut
C. Keeping warm
D. Push ups
Answer:
[tex]\boxed {\boxed {\sf A. \ Osmosis}}[/tex]
Explanation:
ATP or adenosine triphosphate is used as energy in all living organisms. It is required for many processes to keep an organism alive. We are looking for the process that does not require ATP.
A. Osmosis
Osmosis is the diffusion of water across a selectively permeable membrane. It is a type of passive transport, so there is no energy expenditure. ATP is not used, but we can check the other answer choices.
B. Healing a cut
Healing a cut requires transporting substances to the cut, inflammatory responses, and cell division to repair the cut. This does require ATP.
C. Keeping warm
To stay warm the body's blood vessels near the surface constrict so less heat is lost and the sweat glands are inactivated. This requires ATP.
D. Push ups
Push ups require many different muscles throughout the body and exercise requires lots of ATP.
The correct answer is Choice A. Osmosis.

Answer:
Ideas aimed at explaining how organisms change, or evolve, over time date back to Anaximander of Miletus, a Greek philosopher who lived in the 500s B.C.E. Noting that human babies are born helpless, Anaximander speculated that humans must have descended from some other type of creature whose young could survive without any help. He concluded that those ancestors must be fish, since fish hatch from eggs and immediately begin living with no help from their parents. From this reasoning, he proposed that all life began in the sea.

There have been several mass extinctions in the planet's history, such as the extinction of the dinosaurs, but the current mass extinction is different. Greater numbers of species are now going extinct faster than ever before. Also unique to the current mass extinction is the cause. What is causing the current mass extinction
Answer:
There are several actions that not only humans have done to cause mass extinction. There are things such as poaching which is simply killing large and rare animals for horns, fur, meat, tusks, etc. These parts can be sold for money or resources. When one type of animal has characteristics of parts that give the poacher lots of wealth, herds or single animals can be tracked down and killed. The number of these animals dwindle down, and if nothing is done to help the animal, it goes extinct.
But things such as nature itself that can cause extinction where humans can do nothing about. For instance, a frog species called "Splendid Poison Frog " has gone extinct for a certain type of fungus that wiped the entire species out, where we can't do anything about.
There are many results on mass extinction, but these two are some that are caused.

Determine if the process is an example of anabolism or catabolism. French fries are digested in the intestine, breaking them into smaller molecules A body builder exercises to build muscles through protein synthesis A child eats a milkshake, which provides her with energy Process Catabolism
Answer:
--> French fries are digested in the intestine, breaking them into smaller molecules.(Catabolic process)
--> A body builder exercises to build muscles through protein synthesis. (Anabolic process)
--> A child eats a milkshake, which provides her with energy (catabolic process).
Explanation:
CATABOLISM is the process by which living organisms break down large or complex molecules into smaller molecules with the release of energy for their own use. Foods that we consume contains different nutrients which includes carbohydrates, fats &oil, and protein. These nutrients are made available for our body cell use and maintenance through the process of catabolism. Through catabolic processes, these nutrients are broken down into its smaller constituents with the release of energy which is used immediately to power molecular machines that support cell, tissue, and organ function. The following are examples of a catabolic process as it involves breakdown:
--> French fries are digested in the intestine, breaking them into smaller molecules and
--> A child eats a milkshake, which provides her with energy
In contrast, anabolic process involves the building up larger molecules from smaller ones. It uses ATP molecules generated by catabolic reactions as a form of energy to create new molecules that form new cells and tissues, and revitalize organs. For example, muscles can be built from the synthesis of proteins. This is also called anabolic training.
French fries are digested in the intestine, breaking them into smaller molecules - Catabolic process
A body builder exercises to build muscles through protein synthesis - Anabolic process
A child eats a milkshake, which provides her with energy - Catabolic process
Catabolism can be defined as the break down of larger molecules into smaller ones in a series of metabolic pathways of which the energy produced undergoes oxidation and then is released or it is used in another reaction. Digestion is an example of a catabolic process i.e. French fries are digested in the intestine, breaking them into smaller molecules. A child eating a milkshake, which provides her with energy (energy is produced) is a catabolic process.
Anabolism involves the build up of molecules from smaller molecules usually needed for bodily functions. Protein synthesis is an anabolic process (buildup from small amino acids to large proteins. A body builder exercises to build muscles through protein synthesis is an example of anabolism
