If the forest on the hill is cleared, than the soil will lose its natural cover and protection from erosion. The soil will become much more exposed to the erosion, and its top layers will be moved away relatively easy and quickly. Those layers will move downwards, and practically will end up into the river that passes beside the hill. With a significant increase of sediments getting into the river, the river will start to deposit much more material. Also, the sediments will make a problem when there's heavy rainfall because the river will be able to get out of its river bad more easily and cause a flood. The water of the river will also became murkier, muddier, which will make it dark yellowish/light brownish in appearance when there will be rainfall.
Answer:
Indices are used to study fossil specimens and compare them against each other. They are based on concept of ratio hence better than simple measurements when it comes to comparative analysis. They compensate for the problems caused by other variable factors like size or specimen.
For example, to estimate if an organism is long or round headed simple measurement of cranial length or breadth can be done and the result can be given according to the selected parameter. However some specimens will have longer breadth than length and some will have longer length than breadth. So, it is better to measure both the parameters and find out their ratio. Hence, cranial index is used which is given by: (Cranial breadth/Cranial length)*100.
A waste product is a product that is made but isn’t necessarily needed eg. A lightbulb will make light energy but it also makes a waste product heat.
Answer:
Option (1).
Explanation:
IACUC (Institutional Animal Care and Use Committee) is the group that determines the research facilities keep the accordance of the animal welfare act. The ethical issue must be related to animals.
To proceed any research U.S.federal regulation needs approval of IACUC. The research team requires the approval of IACUC for the research proposal before starting his research on the animals. Researchers must follows the protocols made by IACUC.
Thus, the correct answer is option (1).
