Compare and contrast a ridge and a mountain.
The key difference is that a ridge has a continuous crest and a single ridgeline for the whole length of the feature. Mountain ranges usually consist of many smaller ridges.
What are the features of ridges?A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance.
Moreover, four classes of oceanic ridges are considered: spreading-center ridges, fracture-zone ridges, basaltic-volcanic ridges, and island arc ridges.
A ridge is a long and narrow elevation that has steep slopes on either side and stands out from the surrounding lowlands. It also acts as a watershed to rivers that flow down narrow valleys on both of its sides.

Images shows a lake labeled carbonates in water, a cow labeled animal respiration, a tree labeled photosynthesis, a factory labeled factory emissions, the sun labeled sunlight, a cloud labeled carbon dioxide in atmosphere, another tree labeled plant respiration, an arrow from organic carbon to dead organism, and fossils and fossil fuels. Arrows are labeled as follows: A from the sunlight to photosynthesis, B from carbon dioxide in atmosphere to photosynthesis, C from factory emissions to carbon dioxide in atmosphere, D from carbon dioxide in atmosphere to carbonates in water, E from dead organisms to fossils and fossil fuels, and F from plant respiration to the sky.
Using the diagram above, answer the following questions:
6. True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
7. True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
8. Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
9. Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
From factory emissions to carbon dioxide in the atmosphere (C)
The process occurring can be called Combustion. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because the carbon in organic matter is oxidized to form CO2.
from dead organisms to fossils and fossil fuels (E)
The process explained in the question can be stated as Fossilisation. In this process, dead remains of plants and animals are transformed into fossils under pressure. The organic matter is preserved according to the shape of the organism.
from factory emissions to carbon dioxide in the atmosphere (C) & from carbon dioxide in the atmosphere to photosynthesis (B)
Two reactions represent the conversation of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure

What is Punnett square?
A Punnett square is a graphical representation of the possible genotypes of an offspring arising from a particular cross or breeding event. Creating a Punnett square requires knowledge of the genetic composition of the parents.This tool was created in the twentieth century, much after Mendel’s seminal experiments on genetics. However, they are now commonly used to explain the results that Mendel obtained, especially when combined with our current knowledge of DNA, genes and chromosomes.learn more about punnett square below,

What is the approximate pH at which amylases act throughout the digestive tract?
Answer:
6.7 to 7.0
Explanation:
In the digestive systems of humans and many other mammals, an alpha-amylase called ptyalin is produced by the salivary glands, whereas pancreatic amylase is secreted by the pancreas into the small intestine. The optimum pH of alpha-amylase is 6.7–7.0.

The carrying capacity of an environment may be decreased by
Answer:
Carrying capacity can be decreased by disease, an increase in predation, hunting or harvesting by humans, a decrease in available habitat such as habitat destruction by humans, parasites, competition with another species for a resource, or changes in the weather that make the species less suited to the environment.
The carrying capacity of an environment may be decreased by increased activity of predators, diseases, climate change, human activities, habitat destructions, etc.
What is Carrying capacity?Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat.
The carrying capacity of the same habitat may be different for different species. It actually depends on how a species utilizes the resources present in that habitat.
The carrying capacity of any species in its habitat depends on the numer of predators, the flow of diseases, the influence of human activities like overgrazing, industrialization, harvesting, habitat destructions, etc.
Therefore, it is well described above.

B. The note book an archaeologist may keep.
C. Preserved remains or impressions of plant, animal or other organisms.
D. Preserved remains of bones only.
Answer:
C. Preserved remains or impressions of plant, animal or other organisms.
Explanation:
A fossil record is a collection of fossils documenting the history of life on Earth. These fossils can teach us about an extinct organism's size, shape, and/or behavior. The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. A fossil record is not limited to insects trapped in amber or bones, and is not simply an archaeologist's notes.

bonded to one carbon atom. HaC-
Which functional group is
shown in this image?
A. an amino group
B. a methyl group
C. a phosphate group
D. a carbonyl group
Answer:
B.) a methyl group
Explanation:
A.) is incorrect because an amino group has a central nitrogen atom bonded to two hydrogen atoms.
B.) is correct because methyl groups consist of one central carbon bonded to three hydrogen atoms.
C.) is incorrect because a phosphate group contains a phosphorus central atom and four surrounding oxygen atoms. It should be noted that one of the oxygens is double bonded to the phosphorus, while the other three oxygens are single bonded to the phosphorus.
D.) is incorrect because carbonyl groups consist of a central carbon atom double bonded to an oxygen atoms. The carbon is also bonded to two R groups (normally some type of carbon chain).
