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.
Given what we know, we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.
<h3>What we know about evolution. </h3>
- This is a theory that was put forward by Charles Darwin.
- Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
- The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
- These changes are hereditary.
Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.
