How can a calendar year help us to understand the magnitude of geologic time

Biology
1 answer:
Marina86 [1]3 years ago
7 0

Answer:

The civil year allows us to have an idea of how long our planet has existed.

Explanation:

Calendar year is the 12-month period that corresponds to 365 days of the year, counting from 1 January to 31 December. Geological time, in turn, refers to the didactic organization of the evolution of planet Earth and the forms of life that inhabit or inhabited it. It is an instrument used by Earth's geologists and scientists to analyze and chronologically categorize (through the concept of a civil year) the natural evolution of the world in which we live, in order to better understand its past.

The civil year allows geological time to expose the number of years and days that planet Earth (and its forms of life) are in existence.

Emulsion of fatty acids is necessary to _____.
kap26 [50]

Answer:

c. increase the surface area available for hydrolysis by lipase

Explanation:

Emulsification of fats(fatty acid) is a chemical reaction where large molecules(globules) of fats are broken down into a smaller molecules (droplets) by the action of an emulsifier.

In the human body, emulsification takes places in the duodenum during the process of digestion of fats. When large fat molecules have been broken down into smaller fat molecules by action of an emulsifier called bile salts from the gall bladder, a larger surface area is created which makes it possible for the enzyme lipase from the pancreas to react with or act on fat molecules through the process of hydrolysis thereby converting the fats to fatty acids and glycerol for use by the body.

Which of the following statements is true? A thin layer of chyme protects the lining of the digestive tract from being broken do
zheka24 [161]

The correct answer is: Heartburn often results when the gastroesophageal sphincter fails to close properly.

The gastroesophageal sphincter is a muscle located at the bottom of the esophagus that has to be relaxed in order to allow food to flow down into the stomach. After it contracts (tightens), the food and the stomach acid can’t flow back up into the esophagus.

When the gastroesophageal sphincter fails to close properly acid reflux occurs and causes the heartburn.

Which of these is a way to help keep freshwater resources renewable?
never [62]

Answer:

The most appropriate answer would be B. Have factories recycle water.

Recycling of water refers to the process which processed the waste water and convert it to reusable form.

It can be reused for various purposes:

  • Agriculture: irrigating different types of crops, aquaculture etc
  • Urban uses such as irrigating golf courses, public parks, private gardens, roadsides, cleaning of roads, systems involved in fire protection, washing of vehicles, toilet flushing, snow-making etc.
  • Industrial uses: processes that involve water like cooling towers, washing, dust control etc.
  • Environmental uses: It also helps in recharging the surface and ground water, marshes, wetlands, silviculture, wildlife habitat etc.
  • Potable: Recharge aquifers ultimately leads to increase in quantity of drinking water.

Hence, having factories which recycle water helps in keeping the freshwater resources renewable.

"The correct folding of proteins is necessary to maintain healthy cells and tissues. Unfolded proteins are responsible for such
Molodets [167]

Answer and Explanation:

Protein folding : It is the physical procedure by which a protein chain gains its local 3-dimensional structure, an adaptation that is normally naturally useful, in a quick and reproducible way. It is the physical procedure by which a polypeptide folds into its trademark and useful three-dimensional structure from curl. Every protein exists as an unfurled polypeptide or arbitrary curl when interpreted from a grouping of mRNA to a direct chain of amino acids. This polypeptide does not have any steady (dependable) three-dimensional structure (the left hand side of the primary figure). Amino acids cooperate with one another to create a well-characterized three-dimensional structure, the collapsed protein (the correct hand side of the figure), known as the local state. The subsequent three-dimensional structure is dictated by the amino corrosive grouping.

\The right three-dimensional structure is fundamental to work, albeit a few pieces of practical proteins may remain unfurled, so protein elements is significant. Inability to crease into local structure commonly creates inert proteins, however in certain occurrences misfolded proteins have changed or lethal usefulness. A few neuro degenerative and different ailments are accepted to result from the collection of amyloid fibrils shaped by misfolded proteins. Numerous sensitivities are brought about by off base collapsing of certain proteins, on the grounds that the invulnerable framework doesn't deliver antibodies for certain protein structures.
