Answer:
The mass of a substance is constant according to the law of conservation of mass.
Explanation:
According to the law of conservation of mass, matter can never be created or destroyed in a chemical reaction, even though it may undergo change from one physical state to another.
This means that in an isolated or closed system, the mass of matter will always be the same irrespective of the type of change that matter undergoes. This is so because, the mass of a substance is a measure of the quantity of matter in that substance and is constant. The number of particles does not change during a change of state, only their spacing and arrangement. In solid ammonia, the particles are more compact and arranged, whereas in gaseous ammonia, they are more randomly spaced out.
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.
