The natural flow of rivers can be affected by several factors, such as building dams to provide drinking water, pumping of groundwater, climate change, and building of lands that change how natural water runs into surfaces and into rivers. All of these also disrupt the balance of ecosystem in the area.
Answer:
Integumentary is least connected to the Digestive system
Answer:
Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up.
Explanation:
The correct sequence is; Glycolysis-pyruvate-acetyl CoA-krebs cycle-electron transport chain.
Glycolysis is a sequence of reactions for the breakdown of glucose to two molecules of pyruvic acid under aerobic conditions, Krebs cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the energy carriers, while electron transport chain involves a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions and couples this transfer with the transfer of protons across a membrane.
<span>Proteins are large biological molecules consisting of one or more chains of amino acids. Proteins differ from one another primarily in their sequence of amino acids, which is decided by the nucleotide sequence of their make-up, and which usually results in folding of the protein into a three-dimensional structure that determines its job.
</span><span>Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three things: a purine , nitrogenous base a pentose sugar, and a phosphate group.

Basically Proteins are chains of amino acids, nucleic acids are chains of nucleosides (base+sugar+phosphate), and the sequence of nucleic acid results in the specific sequence of amino acids in the protein, finnally determining its shape and function. </span>
