【多选题】How do animal connective tissues consist largely of extracellular matrix?
A.
In connective tissues, extracellular matrix is abundant and carries the mechanical load. In other tissues, such as epithelia, extracellular matrix is sparse, and the cells are directly joined to one another and carry the mechanical load themselves.
B.
Animal connective tissues are enormously varied. They can be tough and flexible like tendons or the dermis of the skin; hard and dense like bone; resilient and shock-absorbing like cartilage; or soft and transparent like the jelly that fills the interior of the eye. In all these examples, the bulk of the tissue is occupied by extracellular matrix, and the cells that produce the matrix are scattered within it like raisins in a pudding; the tensile strength—whether great or small—is chiefly provided not by a polysaccharide, as it is in the cell wall of plants, but by fibrous proteins, principally collagens.
C.
The various types of connective tissues owe their specific characters to the type of collagen that they contain, to its quantity, and, most importantly, to the other molecules that are interwoven with it in varying proportions.
D.
These other molecules include the rubbery protein elastin, which gives the walls of arteries their resilience as blood pulses through them, as well as a host of specialized polysaccharide molecules.

【简答题】帕金森氏病是一种严重危害大脑的疾病。那些在体内不能生成细胞色素P405的人和那些体内能生成这种细胞色素的人相比,在他们进入中老年后,患帕金森氏病的可能性要大三倍。因为细胞色素P405具有使大脑免受有毒化学物质侵害的功能,所以有害化学物质很可能是造成帕金森氏病的重要原因。以下哪项如果为真,最能加强上述论证?( )
