Explain how modern classification is different from linnaeus methods, and why scientists changed it

Biology

SCORPION-xisa [38]3 years ago

The answer is that the criteria of classification change with the improved understanding of organisms around us. During the time of Aristotle, not much was known about the living organisms. So, he classified them as he observed. Plants were classified into herbs, shrubs and trees; very much like what’s taught to a second grade student. Animals as Enaima and Anaima based on the presence or absence of RBCs. After him, Carolus Linnaeus tried his hand over classification. He came up with the 2 kingdom classification: Plants and Animals. He considered only a set of morphological and physiological criteria to decide the kingdom to which an organism belongs. It includes presence of cell wall, mode of nutrition, contractile vacuole, locomotion and others. Based on these criteria, he included widely differing organisms into a single kingdom, for example, fungi, bacteria, algae, and higher plants were included into plant kingdom just because they have cell wall as a common aspect. Then came, Ernst Haeckel, who came with a third kingdom of Protista to include unicellular organisms. Copeland gave a 4 kingdom classification segregating unicellular organisms into 2 separate kingdoms based on their nuclear structure. R.H. Whittaker came next introducing the most accepted 5 kingdom classification system. You should understand one thing that man’s knowledge of classifying organisms improved with the improving technologies available to him, which he exploited to very effective extent. Carl Woese gave the 6 kingdom classification and 3 domain system based on the 16S rRNA sequence.

Our understanding of organisms around us is improving day by day and the system of classification will also change further in pace with the improvement in technology.

I hope this helps! :D]

What factors might affect the production of more or less foam and gas in this experiment (e.g mor yeast, different types of suga
m_a_m_a [10]

More yeast gives more foam while the use of too many different types of sugars gives less foam.

Fermentation:

It is the process by which organisms break down glucose (sugars) to produce energy in the absence of the oxygen. During the fermentation, many types of by-products are formed such as alcohol, carbon dioxide, and acids.

In fermentation, the bubbles or gases, are produced by yeasts.

  • Here, if the amount of yeast is increased then the number of bubbles or foam will also increase.
  • If too many different types of sugars are used the number of bubbles or gases will decrease because yeast can only digest a certain type of sugars only.

Therefore, more yeast gives more foam while the use of too many different types of sugars gives less foam.

Which sequence of events best explains the interaction between the components of the Arctic ecosystem feedback loop
nikitadnepr [17]

The sequential events in the Arctic ecosystem feedback loop are: Global temperature increases → permafrost thickness decreases → methane increases → global temperature increases. It is harmful to the Earth.

The Arctic ecosystem is a feedback loop because the warmer the temperatures, the less sea ice (permafrost) is observed.

The Arctic ecosystem feedback loop is a dangerous phenomenon because it accelerates global warming.

Permafrost refers to ice ground that remains completely frozen (0°C) for at least two (2) or more years straight.

In addition to naming species, Linnaeus also grouped species into a hierarchy of increasingly inclusive categories. The largest
Semmy [17]

Answer:

The correct answer is D) domain

Explanation:

The father of taxonomy is Linnaeus. Taxonomy helps in classify and naming organisms. The modern taxonomy has eight levels of classification. Domain, kingdom, phylum, class, order, family, genus, species.

Domain is the highest level of classification so it is the largest category that would include closely related species. When we go from domain towards species the number of similarities increase and number of organism decrease and vice versa is true when we move from species to domain. So the right answer is domain.
