Taxonomy is the branch of Science, in which
we study the Classification of Organisms. On discovering an unknown organism,
begin classification by looking for anatomical features that appear to have the
same function as those found on other species.
In order to correctly classify an organism,
scientists use many modern tools.
1.Morphology describes the physical
characteristics of an organism. Typically, this is enough information to place
the organism within a domain and kingdom.
2.DNA and biochemical analysis allow
scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to
group organisms that share common fetal development.
<span>4.Evolutionary
phylogeny describes the evolutionary relationships between organisms.</span>These
relationships are deduced based on shared traits that may have been passed from
ancestor to new species. Traits
may include physical traits (ex. presence of jaws), or may be genetic traits
(shared genes).
Answer:
When the salt water is mixed with fresh water,it is called brakish water which have the salinity 0.5 to 35 ppt.
Explanation:
The mixing of fresh and salt water is important for aquatic organisms.
The catadromous fish born in marine habitat but they spend their rest of life in the fresh water where growing and maturation takes place.
Ex- Eel is the common example of catadromous fish.
Like wise,
Anadromous fish born in fresh water and spends their life in the sea and return to fresh water for spawning.
For example Salmon, smelt, shad, are common examples.
Thus mixing of water is important for breeding and growing of these fishes.
More over, the brakish water contain world's most diversified life forms.
Answer:
I choose A, it seems loke the best choice
Explanation:
<span>#1) What are saber teeth for these organisms?
Answer: After reading the statements presented above you can conclude that the saber teeth are Analogous structures for these organisms. The reason being that they can be considered as similar features. This usually happens when different organisms live in similar environments, they evolve in a similar way.

A magnitude-5.0 earthquake releases about <u>32</u> times more energy than a 4.0 magnitude earthquake.
Explanation:
The characteristics of an earthquake are mostly measured through its magnitude and intensity.
A earthquake will generate seismic energy waves which will spread outwardly on the earth's surface in all directions.
The magnitude of an earthquake is the quantitative measure of the amount of energy released during a seismic activity or an earthquake.
The intensity of an earthquake is a descriptive measure of the severity or the strength of the earthquake based on the impact it has done on the earth’s surface, human population, and other man-made structures on the earth and the potential danger.
The magnitude measured using a seismograph is expressed as a whole number or a decimal fraction like 5.7, 4.5 etc. The severity of the magnitude is compared against the standard Richter’s Scale.
The intensity is denoted in Roman numerals and compared against various scales like Mercalli or Rossi-Forel Scales.
Based on the logarithmic application of the scale, each whole number increase in an earthquake’s magnitude depicts a ten-fold increase in severity of the amplitude of the earthquake as measured on the seismogram and denotes about 32 times increased energy release
