Answer:
The stomach of a cattle and other ruminants include a pouch like structure called a recticulum, where bacteria help breakdown the animals food.
Explanation:
Cattle is a ruminants and ruminants animals are animals that can chew the cord and have four chambered stomachs. Their stomachs are rumen, recticulum, abomasum and omasum. The abomasum is considered the true stomach because it has a structure similar to that of non ruminants. Recticulum is the second chambered stomach that is pouch like and it contains bacteria they help breakdown food. It collect the small digests molecule and move them to omasum.
It helps scientists improve on research and tests/examinations to understand the object a little more. For Example: The newer modified microscope helps zoom into harder to see microrganisms. So if technology changed then most of our scientific knowledge wouldve been mistaken this whole time. We wouldnt know many things if technology didnt exist.
