Answer: Notochord,Nerve cord, pharyngeal gills
Explanation:
1.Presence of notochord that gives them skeletal support this also develops into between Column in vetertebrates.
2.presence of dorsal hollow nerve cord that develops into the brain and spinal cord which is the nervous system. develops into the central nervous system
3.presence of pharyngeal slit that develops into gills in some aquatic organism and its develops into jaw in some mammals. The gills is use for removal of water that enters the mouth while feeding.
<h3>Oxidative Phosphorylation</h3>
Explanation:
The process by which ATP is generated by utilizing the large amount of energy released during the transfer of electrons from NADH or FADH₂ to the O₂ through a series of electron carrier present in the mitochondrial membrane is called oxidative phosphorylation.
The process of electron transfer is accompanied by the pumping of protons across inner membrane of mitochondria, from the mitochondrial matrix to intermembrane space establishing electrochemical proton gradient.
The ATP synthase complex present in the mitochondrial membrane allows the protons to move down the proton gradient as a result enough energy is released to add a phosphate group to ADP and form ATP inside the mitochondrial matrix.
Thermocline - <span>a steep temperature gradient in a body of water, that is marked by a layer above and below at which the water is at different temperatures.
halocline - </span><span> a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water.
pycnocline - </span><span>a layer in an ocean or other body of water in which water density increases rapidly with depth.</span>
Acetic acid is formed by these elements:
Methanol, a type of alcohol also known as methyl alcohool.
Carbon monoxide, a atype of toxic gas formed by an atom of carbon and an atom of oxygen.
