Matrix
Metalloproteases (MMPs) are a part of metalloproteinase enzymes family playing
an vital part in healing wounds such as physiological or pathological processes
and even in morphogenesis, reproduction, embryonic development, tissue
remodeling, arthritis, cancer and cardiovascular disease. MMPs are a product by
activated inflammatory cells (neutrophils and macrophages) and wound cells
(epithelial cells, fibroblasts and vascular endothelial cells).

MMPs (MT-MMPs) is a subgroup of MMPs which is helpful in breaking down of
extracellular material as well as in handling of biological molecules varieties. </span>
Answer:
. The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles. In animal cells, the mitochondria produces the majority of the cells energy from food.
Answer:
M.Leakey was a paleoanthropologist of no formal university education and British origin. Her major discoveries were;
1. the proconsul skull
2. Zinjanthropus skull at Olduvai Gorge In Tanzania
3, system of classification of discovered stones.
4.Laetoli footprints at Laetoli sites.
However, her most outstanding discoveries were proconsul skull ( projecting face with no browridges, and presence of ape-like teeth shapes) and the Laetoli prints. She believed the skull belonged to ancestral Homo habilis, which could be traced to origin of mankind.
The discovery of Laetoli prints showed evidences of bipedalism and the origin of Australopithecus. These prints and the skeletons she unearthed proved that the ancestral of human race actually walked upright, nearly four feet tall in height.Hence she concluded that these prints actually belong to the Australopithecus. This brought a paradigm shift in modern understanding of human evolution of prehistoric times and the origin of mankind,
Her discoveries generally throw light on the <u>evolution of mankind </u>and new understanding of <u>genesis of human race</u>
