Answer:
Scientists must collect accurate information that allows them to make evolutionary connections among organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic. In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution. For example, the bones in the wings of bats and birds have homologous structures (Figure 1).
Figure 1. Bat and bird wings are homologous structures, indicating that bats and birds share a common evolutionary past. (credit a: modification of work by Steve Hillebrand, USFWS; credit b: modification of work by U.S. DOI BLM)
Notice it is not simply a single bone, but rather a grouping of several bones arranged in a similar way. The more complex the feature, the more likely any kind of overlap is due to a common evolutionary past. Imagine two people from different countries both inventing a car with all the same parts and in exactly the same arrangement without any previous or shared knowledge. That outcome would be highly improbable. However, if two people both invented a hammer, we can reasonably conclude that both could have the original idea without the help of the other. The same relationship between complexity and shared evolutionary history is true for homologous structures in organisms.
Answer:
How does fragmentation of ecosystems cause problems for the species living in it?
Ecosystem entails the relationship between organism and the environment, fragmentation of such ecosystem breaks the relationship, hence; causing unbalance ecosystem
Explanation:
Answer:
Flavin adenine dinucleotide
High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. Glycolysis is the first of the three steps used to breakdown glucose to produce ATP. Glucose, a 6 carbon sugar, is split into two 3 carbon sugars.
Formula: C27H33P2N9O15
