In the absence of oxygen, glycolysis is followed by _________ in human cells
Fermentation
Answer:
The correct answer is ''proteins.''
Explanation:
Transport phenomena are essential in living beings, either to carry a hydrophobic molecule through an aqueous medium (transport of oxygen or lipids through the blood) or to transport polar molecules through hydrophobic barriers (transport through the cell membrane). Biological transporters are always proteins. Proteins are capable of carrying out specific functions such as the selective transport of molecules, or certain enzymatic reactions, among others. Membrane proteins can be peripheral or partially or totally integrated into the membrane, being, generally, globular or fibrous. Its activity is essential for the maintenance of transmembrane gradients. Thanks to membrane proteins, the exchange of molecules such as nutrients or waste products takes place, as well as the reception of external signals. Among its functions are channel-forming: Integral proteins arranged in the membrane in such a way that they give rise to the formation of a pore or channel, usually hydrophilic. These pores or channels allow the entry and exit of certain substances from the cell.
Answer:
can lead to natural selection
Explanation:
<h2>
</h2><h2>
Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>
This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>
So overtime, the organism which is weaker (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in a way "<u>Nature selected"</u><u> </u>the better fit organism.
