Answer:
Both molecular and morphological comparisons among dugongs and proboscideans species should be conducted
Explanation:
From a molecular biology point of view, it is possible to compare the sequences of dugongs and proboscideans and thus observe the homology level between genes of interest, it in order to establish evolutionary relationships among species. Moroever, by mass spectrometry (MS), it is possible to compare proteins in fossils >1 million years, these comparisons may shed light on the evolutionary origin of one group
An advantage of a filter is it cleans the water better then the screen
A disadvantage is that you need to wash and sometimes fix the filter
Euglena is green in color because of the chlorophyll that is contained in the chloroplast of that organism and the body structure that is located at its base is known as flagellum
.
Explanation:
Euglena are species that are found in the fresh and salt water. They are abundantly found in inland waters where they manage themselves to bloom in large amount and color the water surface of ditches and ponds green.
This green color which them form are mainly due to the chlorophyll that is contained in the chloroplast of the organism. chlorophyll is known to be the pigment that is responsible for the green color.It is the cause for the green color in this case too.
Euglena contains a specialized body structure which is located at the base of the tail by which it manages to move.
This specialized structure is known as Flagellum.
Answer:
Although direct calorimetry is considered to be the most precise technique for the measurement of metabolic rate, construction of such a chamber that is large enough for doing exercise physiology research (or any research for that matter) is extremely expensive and not at all mobile.
Explanation:
Direct calorimetry measures the heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to surrounding water. This is a very accurate method of measuring energy expenditure.
