Answer:
The correct option is 3
Explanation:
An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.
The third option can be easily answered using the "requirements" above.
The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls
The aim would be to determine the effect of different types of grass on the movement of a ball
The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.
Answer:
Water pollution is one of the most common type of pollution that leads to the deterioration of the water quality mainly due to the man-made interference. Direct and indirect pollution are two of its types. Direct pollution as the term suggests refers to the direct flow of pollutants in the water in contrast to the indirect pollution that accounts for the transport of pollutants eventually to the water body.
Explanation:
Direct pollution is characterized by the release of toxic fluid directly in the water body. The main source of this type of pollution are the toxic pollutants from the large factories. Some of the other sources includes solid waste from the household activities and waste from agricultural practice like fertilizers, and the waste generated by the waste water treatment plant.
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>
