1 answer:
denis-greek [22]3 years ago
6 0

Answer:

Questions, hypotheses, and ideas should be tested against observable evidence.

Explanation:

Skepticism is extremely important, if not fundamental, in all areas of Science. This attitude is based on the belief that all questions, hypotheses, and ideas should be tested against observable evidence. Moreover, it allows scientists to <u>question and think thoroughly about all possibilities behind a phenomenon, instead of just 'believing' any observation or vague and non-supported reason that explains it.</u>

In addition, it allows researchers to investigate all possibilities and test numerous methodologies to be certain and gather enough evidence to explain this certain phenomenon.

Which discovery in the 1800s lead to the development of germ theory
bogdanovich [222]

<u>Answer:</u>

Discovery of vaccine for smallpox, viruses and actual organisms that cause many diseases lead to the development of Germ Theory.

<u>Explanation:</u>

  • Theory was the 'predominant theory' of 'disease transmission' before germ theory but it is no longer accepted as a 'scientific theory' of diseases.
  • 'Formal and reliable experiments' on germs and diseases relationship were 'conducted by Louis Pasteur'.
  • He showed that growth of microorganisms was not a spontaneous generation and his pasteurization experiment provided key pieces of evidence that supported germ theory.

How many distinct stages must occur between the point when light first encounters chlorophyll and the point at which
Novay_Z [31]

Explanation:

<u>Three.</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  This occurs in distinct steps: 1) light fixation,  2) electron transport and NADPH production 3)  ATP generation, then 4) carbon fixation and carbohydrate production.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.

Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
  • This happens in the thykaloids, where pigment molecules reside like chlorophyll.
  • Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.
