Metabolic pathways involve a series of biochemical reactions converting substrates to final products through anabolic and catabolic pathways.
Metabolic pathways are a series of sequential biochemical reactions that convert a substrate molecule through a series of metabolic intermediates to yield a final product. Anabolic pathways build complex molecules from simpler ones, requiring energy, while catabolic pathways break down complex molecules into simpler ones, producing energy. This balance between building (anabolism) and degradation (catabolism) constitutes metabolism.

Answer: the answer would be 5 are there on the top the answer would be 15.000 because they both can go in and into each other if you did multiply 5 times 3 equals 15
Explanation:
The graph shows exponential population growth.
We can tell this because the population size increases rapidly over time, without showing any signs of slowing down or leveling off. This is characteristic of exponential growth, where the population grows at a constant rate.
In contrast to exponential growth, logistic growth shows a period of rapid growth followed by a leveling off as the population approaches its carrying capacity (the maximum population size an environment can support).

Which of the following is the most specific group used to classify organisms?
Final answer:
The most specific classification category for organisms is the species, which represents a group capable of interbreeding and producing fertile offspring. It is the final and most precise category in the Linnaean system of taxonomic classification.
Explanation:
The most specific group used to classify organisms within the modern taxonomic classification system is the species. This system, also known as the Linnaean system after its inventor Carl Linnaeus, organizes life forms into a hierarchy from the least specific to the most specific categories. The order from the broadest to the most specific is: domain, kingdom, phylum, class, order, family, genus, and species. The species is the most precisely defined category, representing a group of organisms that can interbreed and produce fertile offspring. Under the binomial nomenclature system, each species has a unique two-part scientific name consisting of its genus and species designations, such as in Homo sapiens, where 'Homo' is the genus and 'sapiens' is the species.

Pure substances are made up of single elements or compounds. (2 points) True False
Answer:
true
Explanation:
The statement is true as pure substances consist of only one type of matter, which can be an element or a compound. Elements are made of single types of atoms, while compounds are composed of two or more types of atoms chemically bonded together.
Explanation:The statement 'Pure substances are made up of single elements or compounds' is true. A pure substance has a constant composition and properties that are constant throughout the sample. By definition, pure substances can either be elements or compounds. An element is the simplest form of matter composed of only one type of atom and cannot be broken down into any simpler substance through chemical means. For example, aluminum is an element. A compound, on the other hand, consists of two or more types of atoms chemically bonded together, such as water, which is made up of hydrogen and oxygen atoms. Therefore, pure substances maintain a uniform composition and exhibit definite physical and chemical properties.
. A pure substance is a type of matter that has a constant composition and properties that are constant throughout the sample. Elements are the simplest substances made up of only one type of atom, while compounds are substances that are made up of more than one type of atom.

Describe how humans’ way of life has changed. Begin with hunter-gatherers and end with life after the Industrial Revolution.
Answer:
Ever since the existence of life of humans on Earth, the humans have been making progress to understand themselves and the mother nature.
In the start, the humans were hunter- gatherers. Hunter- gatherers can be described as humans which use wild life plants and animals for food. The humans used to live in jungles and eat the wild- life plants and animals. They used leaves from the trees to cover their bodies. Heat was produced by rubbing the rocks.
After this time, the humans learned the techniques of cultivating plants for food. They started cultivating crops and depend on them for living. During this time, humans learned the art of farming and agriculture. But they couldn't understand the effects of various pathogens infecting the crops and humans at that time.
After this time, humans learned the art of preserving foods in different forms like pickles etc. They also learned that certain types of plants could be used to treat wounds and other diseases.
With the passage of time, people learned to make and use machinery for making their tasks easier. The usage of machinery progressed rapidly and the industrial revolution began. People became more diverted to this sector rather than farming. They started to move towards the cities to find better jobs in industries.
Life after industrial revolution was much easier as humans had made a lot of equipments which aid them to have a better life style. Science has been developing since that time day by day.

Which of these describes a method in studying plate movements?
-Observing the absence of magnetic rocks in locations that do not match the poles
-Match relief elements only on the western side of the Atlantic Ocean
-Recording the spread of the seafloor in the mid-Atlantic region
-Correlate the rotation of Earth to plate movement
Answer:
C: Recording the spread of the seafloor in the mid-Atlantic region .
This describes a method in studying plate movements
Explanation:
Seafloor spreading is the ‘process’ by which oceanic crusts are formed as a result of volcanoes. Then these crusts slowly drift away from the edge/ridge. It usually occurs at mid-ocean edges.
When plates move, they collide. Because of these collisions volcanoes and earthquakes occur. Volcanoes occur when one plate sinks under another plate. This allows the lava to get inside the plates and volcano occurs after the build-up of this magma or lava. Earthquakes are caused when two plates collide and slide with each other. Thus, Option C is the correct answer as plate movements eventually cause se floor spreading.
Black mice and tan mice are native species that are observed in a particular region. Human habitation in the region caused an invasive mouse species to enter the region. These mice are brown and share the same food requirements as black mice. Tan mice have different food requirements. How will this change affect the web in the region?
Answer:
Black mice will be at competition

Answer:
There are many similarities and differences between the two cultures.
Explanation:
Similarities are as follows: -
Anti-regime movements in both Eastern Europe and Middle East brought many political and military changes. Regional concentration is good in both type of cultures which is evident even on the map.Differences are as follows: -
Eastern Europe states were not autonomous. There was stability in the region, Middle east has mix culture, on the other hand, with different levels of autonomy. In Eastern Europe, there were many protesters or revolutionists who were though in small number were popular and had great influences over people. But, even large number of opposition leaders in Middle east, they were not that effective.Georgia's overall coastal habitats were rated and the results can be seen in the bar graph. The coastal habitats by in large were rated as "fair". One important indicator in the graph is the chlorophyll a category. Explain how the ratings for chlorophyll a might influence the overall ratings of coastal habitats. A) The algae that contains chlorophyll a can be detrimental to other life forms. As algae increase the total organic carbon increases. B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop, C) Chlorophyll, a plant pigment, is measured to indicate the amount of algae in the water. The more chlorophyll a present, the more plant growth and the healthier the aquatic environment. D) There is a direct correlation between algae present and benthic organisms. The more algae, the more benthic invertebrates. That means more abundant food for other animals in the coastal habitats.
Answer:

Explanation:
The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develops. periodt pooh
Answer:
The answer is: B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.
Explanation:
"Eutrophication" is the enrichment of surface waters with nutrients for plants, both nitrogen and phosphorus contribute to eutrophication.
A lake with total concentrations of phosphorus and chlorophyll-a of 10 and 2.5 mg / m3 respectively, can be classified into different eutrophication classes.
The symptoms and effects of eutrophication are as follows:
· Increased production and biomass of phytoplankton, associated algae and macrophytes.
· Production of toxins by certain algae.
· Deoxygenation of water, especially at the end of algal growth situations.
The answer is: B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.

1. Elephant seals from Antarctica dive into the ocean more than 1,500 meters deep at a time—nearly a mile. A seal can stay underwater for an hour or longer. To do that, the seal stores oxygen in its blood cells that is slowly released as it dives. The seal does not expend any extra energy releasing the oxygen stored in its blood cells. Do you think passive or active transport is at work in the blood cells of the elephant seal? Explain your answer.
Explanation:
Passive transport is at work- the release of oxygen is a passive process, not requiring energy.
Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.
However, via passive transport or diffusion, small molecules can move from regions of high concentration to regions of low concentration until an equilibrium is reached. This occurs along the concentration gradient, and usually involves small non polar molecules in cells such as oxygen and carbon dioxide.
The passive process is more efficient, as ATP production for active transport requires oxygen; the O2 stores in the blood cells would be depleted quickly. This limits the depth at which the seals can dive, due to their need to resurface to replenish O2 stores.

Which describes an oxidation reaction that occurs during cellular respiration?
Answer:
Glucose loses electrons and hydrogen to form carbon dioxide.
Explanation:
During aerobic respiration, oxygen is reduced, donating an electron to hydrogen to form water. The entire process of cellular respiration oxidizes glucose. The oxygen taken in by a cell combines with glucose to produce energy in the form of Adenosine triphosphate (ATP), and the cell releases carbon dioxide and water. This is an oxidation reaction in which glucose is oxidized and oxygen is reduced.
