Answer:
This is evolution.
Explanation:
Based on the system of Cladistics,some systematists are basing organism classification on the period in which they appear or evolved on earth.Therefore species of organism which evolved first are said to be the early organism, and appear higher in the level of classification,while those that evolved later are lower to these organisms in the evolutionary tree.
Simply put,Evolution refers to the progression of changes in an organism overtime.It is as a result of the ability of species of organism to withstand the selective pressure because of the presence of certain inheritable adaptive traits, compare to other organisms in the population.The organisms with these traits are naturally selected.
Therefore, the species of organism with the ability to evolved due to natural selection,are placed higher in the classification tree, while other organisms which evolved later,thus with lesser resistance to the selection pressure are placed below.
Therefore if these traits is in their DNA ,and are responsible for evolution,then classification based on evolution helps to understand the hierarchy by which different organism species appear.Hence evolution and classification are related.
Answer:
Exchanger or antiporter
Explanation:
The cotransporters are transmembrane proteins that are part of the active transport. These proteins couple the movement of a molecule or ion against its concentration gradient with the movement of one or more cotransporter ions under its concentration gradient, thus allowing the passage of large molecules such as glucose into the cell that transport Passive would not be possible to enter. There are two types:
Simporters:
They are transmembrane molecules that involve the movement of two or more different ions through the phospholipid membrane of the membrane in the same direction. Generally the ions move under the electrochemical gradient allowing the other molecule to move against the concentration gradient.
<u>Exchanger or antiporter (countertransporter)</u>:
They are transmembrane molecules that involve the movement of two or more different ions through the phospholipid membrane in opposite directions, where one species of the solute moves in favor of the electrochemical gradient, allowing the other species a movement against their gradient of concentration
