Scientists recognize seven living species of sea turtles, which are grouped into six genera. Each sea turtle has both a scientific name and a common name. The scientific name identifies the genus and species, and the common name typically describes some characteristic of the turtle’s body.
Different species of sea turtles like to eat different kinds of food. Sea turtles have mouths and jaws that are specially formed to help them eat the foods they like. And each species of sea turtle eats, sleeps, mates and swims in distinctly different areas. Sometimes their habitats overlap, but for the most part they each have different preferences.
The Central Dogma states that genetic information flows in one direction. It is the process of copying a DNA sequence to make RNA which is being decoded to make the protein. Process of DNA to RNA to Protein
The wood has the most friction because the final speed is less than the others when the fan is on and the cart slowed down the fastest when the fan is turned off.
Some bacterial toxins cause disease by altering the activity of G protein, cholera toxin is one of them
Cholera toxin catalyse ADP ribosylation of Gs and blocks GTPase activity thus Gs GTP become permanently active
Constitutive activation of Gs protein continuously induce adenylyl cyclase, cytosolic cAMP level rises that leads to activation of protein kinase A (pKA)
Activated pKA catalyse phosphorylation of two transmembrane proteins of intestinal epithelial cells:
CFTR cause excessive outflow of Cl- ion and Na+ H+ exchange cause efflux of Na+ ion, both enters in gut and form Na+ Cl-
Na+Cl- leads to outflow of water from the gut, resulting in diarrhea and dehydration and this condition may cause death of organisms due to loss of water and ions
