Answer: mechanical weathering
Explanation:
Weathering is the breaking down of rocks into small fragments or pieces by agent such as animals,water, wind. Erosion helps in the transport of this materials from its region to another.
Mechanical weathering is also known as physical weathering, it causes rocks to crumble as a results of disaggregation of rocks which could results from cracks, freeze thawing.
Water is an important agent of mechanical weathering, in either liquid or solid form.
Liquid water can seep into cracks and crevices in rock as in the case of Lurray Caverns in Virginia,and rock fragments will be eroded this materials accumulation of this leads to a new formation of calcite. If temperatures drop low enough, the water will freeze creating an expansion in the rock that could results in a crack or fragments of rocks falling off.
Answer:
green-flowered plants
Explanation:
In biology, blending inheritance refers to an erroneous theory from the XIX century, which proposed that the progeny (F1) inherits phenotypic traits as an average of parental phenotypic values. If this theory would be true then a crossing of a blue flower variety with a yellow variety of the same species would produce green-flowered progeny (since green is a combination of blue and yellow). Charles Darwin used pangenesis, a hypothetical mechanism for heredity that implied blending inheritance, in order to understand the transmission of hereditary characters. Darwin believed that different parts of the body generated heredity particles called 'gemmules' that aggregated in the gonads, and contributed to the transmission of heritable information to the next generation. The blending inheritance theory was replaced by Mendelian inheritance during the early 1900s.
