Explanation / Answer

(1) C)H.erectus

Both H. heidelbergensis and Homo erectus share a number of features like projecting face and brow ridge, sagittal keeling, low frontal bone and a thickening of bone along the top of the skull from front to back, all this similarities strengthen the evidence that H. erectus are the predecessor of H. heidelbergensis found in the fossil record.

(2) c. blocking the inflammatory response

When bacteria digests the fiber in the colon, it produces copious amounts of butyrate and the fermentation of fiber will provide energy to other bacteria, the bowel epithelium and peripheral tissues. And this also increase the number and activity of anti-inflammatory immune cells and thus block the inflammatory response.
