The number is unknowable because there are soo many germs on animals
<span>An animal that has body parts that extend outward from its center show radial symmetry. The body plans of echinoderms, ctenophores, cnidarians, and many sponges and sea anemones show radial symmetry. A coelom is a body cavity completely lined with mesoderm. The coelom exists in multicellular organisms.It is a fluid-filled body cavity that is completely lined by tissue created from the mesoderm.</span>
The causes of changing the pH of milk into yogurt are that the lactose in the milk is converted into lactic acid, which leaves the pH.
<u>Explanation:</u>
When the pH drops below pH5. The micelles of the caseins, a hydrophobic protein, lose its territory structure due to the protonation of the amino acid residues.
So the production of the amino acids forms the basic structure and texture of the yogurt. To turn the milk into the yogurt the first process is to ferment the milk and turning the lactose sugar in the milk into the lactic acid, then the lactic acid converted into the yogurt.
It has all the requirements of a living being
