Answer: The aswre is c
Explanation:
When warm air from a large body of water moves quickly into a land area of cold air, we can expect precipitation to occur were the two air masses meet. The ingredients for a thunderstorm are moisture, unstable air and lift. You need moisture to form clouds and rain. You need unstable air that is relatively warm and can rise quickly, and you need lift. This can form from fronts, sea breezes or mountains.
A pond fills with organic matter during eutrophication.
Explanation:
Eutrophication takes place when an environment like aquatic environment in the form of lakes, ponds, sea etc is filled and enriched with organic matter and nutrients.
This is a huge concern for aquatic or marine organisms as the excess nutrients give rise to algal bloom due to production of huge amounts of phytoplanktons. These phytoplanktons will use and deplete the reserves of oxygen present in the water, leaving very little or none for other aquatic or marine organisms. This leads to destruction of such organisms which require oxygen to survive and finally their endangerment and extinction.
Natural eutrophication occurs due to gradual and slow sedimentation process occurring over very long periods of time.
Artificial or man-made eutrophication due to sedimentation of organic waste from solid wastes, industrial effluents increases the nutrient content like nitrogen in the water bodies resulting in rapid and mass eutrophication disturbing the entire ecological system.
A pond fills with organic matter when "pond ages from oligotrophic to mesotrophic".
Explanation:
The ponds are basically ranging from youngest to oldest in the given categories: Oligotrophic, Mesotrophic, or Eutrophic phases of live. The oligotrophic ponds are known as fresh or young waterbody. Oligotrophic bodies are low in nutrient quantities, like nitrogen and phosphorus, so donot encourage algae and aquatic plants productivity. The middle ages mesotrophic aquatic bodies are carrier of more nutrients and thus more readily the development of plants and algae take place than oligotrophics, but less than eutrophic production. As aging take place from oligotrophic to mesotrophic, the pond sides continue to slope less and the base of the pond starts to fill in with organic matter.
Fossils can be formed from all the things that are mentioned in the options. Hence, option D is the correct answer.
A fossil is described as the preserved traces or remains of the organisms that are dead. The process that is involved in the formation of fossils is termed fossilization. A fossil can preserve the complete organism or just only part of one. Some of the examples that can become fossils are:
Thus, we can conclude that the fossils can be formed by all the things mentioned in the options as they all are remains of the organisms that are dead. Thus, "all the above" is the correct answer.

1. Answer is "it provides all the elements for lipids".
The elements of glucose are carbon, hydrogen and oxygen. Hence, if the molecule glucose were broken down, those elements are released.
The elements of lipids are same as glucose. But sometimes lipids contain sulfur and phosphorous.
In proteins there is nitrogen as element other than carbon, hydrogen and oxygen.
Nucleic acids also have carbon, hydrogen, oxygen, nitrogen and phosphorus as elements.
Hence, glucose molecule cannot provide all the elements for proteins and nucleic acids but can provide elements for most of lipids.
2. Answer is “NO”.
The four types of macromolecules are carbohydrates, lipids, proteins and nucleic acids. Elements of those macromolecules are as follows.
Carbohydrates - carbon, hydrogen, and oxygen
Lipids - carbon, hydrogen, oxygen sometimes nitrogen and phosphorus.
Proteins - carbon, hydrogen, oxygen and nitrogen sometimes sulfur and selenium.
Nucleic acids - carbon, hydrogen, oxygen, nitrogen and phosphorus.
Sugars are also type of carbohydrates. Hence, sugars can provide only carbon, hydrogen, and oxygen as the elements. Therefore, sugars cannot provide all the elements that needed to make four types of macromolecules. But sugars can provide elements to make carbohydrates and most of lipids.
Answer:
Sedimentary rock
Explanation:
The Coquina rock is a sedimentary rock that is comprised of broken fragments of the shells of ancient trilobites, invertebrates, and brachiopods. When the sediments were deposited, and shells were also added on it, they have undergone compaction and lithification, as a result of which these rocks were formed. They are generally classified as the soft limestone rocks, that are typically formed in the marine and lacustrine environments, where the flow energy is very high.
Thus, Coquina is a sedimentary limestone rock.
Answer: sedimentary.
