Two scientists produce two different cladograms for the same group of organisms. Explain how the differences are possible.
S_A_V [24]

Answer:

Due to different grouping style

Explanation:

There are two modes of classifying an organism due to which two different cladogram are produced-  

A) When the organisms are grouped together on the basis of similarities shared by them – Such species are named based on the name of older species and the newly discovered species sharing similar traits are kept under older species thereby dropping its own name.  

B) In the second method, the minute differences are observed in species to group them into several branches arising from one parent organism.

Mitochondria are thought to have evolved from ancient bacteria. Free-living bacteria have lost motility in mitochondria over time.

<h3>What is endosymbiosis?</h3>
  • Endosymbiosis is the term used when one organism truly lives inside the other. According to the endosymbiotic theory, it is simple for a big host cell and ingested bacteria to become dependent on one another for survival and develop a long-term bond.
  • Due to their increased specialization through millions of years of evolution, mitochondria and chloroplasts can no longer survive outside of cells.
  • Chloroplasts and mitochondria are remarkably similar to bacterial cells. They have unique DNA that is distinct from the DNA found in the cell's nucleus.
  • Additionally, these organelles synthesize numerous proteins and enzymes necessary for their functions using DNA. Both mitochondria and chloroplasts are surrounded by a double membrane, which is additional proof that each was ingested by a primitive host.
  • Similar to bacteria, the two organelles also divide by themselves and replicate their own DNA.

Which of the following best explains the relationship between temperature and this enzyme?
DochEvi [55]
<h3>Answer:</h3>

Enzymes functions in a specific temperature range.

<h3>Explanation:</h3>
  • Enzymes are biochemical catalysts whose function is to speed up the rate at which chemical reactions occur.
  • Enzymes work best at a specific range of temperatures known as optimum temperature.
  • Low temperatures below optimum levels deactivate the enzyme and thus lowering the rate of enzyme activity.
  • Extreme temperatures, on the other hand, denatures the enzyme altering enzyme's active sites making it difficult for substrates to fit.
