The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
Answer:
Paul uses Irradiation. The technique uses gamma rays
Explanation:
Answer:
Genotype of parents is Rr
Explanation:
Let the allele for red flower be represented by "R" and the allele for white flower be represented by "r"
Allele for red color is dominant over allele for white color.
Co-dominant causes the expression of characteristics associated with dominant allele only.
Genotype of parents is Rr
Rr * Rr
RR, Rr, Rr, rr
"rr" is white colored flower
"RR and Rr" is red colored flower
D Bc I just did it and got it right
Answer:
Vascular system - phloem and xylem
Explanation:
The phloem is responsible for translocating nutrient and sugars which are produced by the leaves to areas og the plant that are metabolically activew while the xylem cell wall transport water gom the root to the leaves.
However, a plant may have many xylem tissues extending up to the plant.
