Explanation:
In thermoplastics, the arrangement of monomeric units is linear and in thermosetting plastics, it is cross-linked. Thermoplastics are usually soft, weak and less brittle, so can get soften on heating and stiffen on cooling. They can be melted, remoulded and recycled easily.
Given:
Allele for green pod colour = Gg (Heterozygous)
Allele for Yellow pod colour = gg (Homozygous)
Explanation:
Parents: Gg x gg
When this two parent are crossed, it leads to the following F1 generation (off springs):
<em>• Gg (green colour pod)
</em>
<em>• Gg (Green colour pod)
</em>
<em>• gg (Yellow colour pod)
</em>
<em>• gg (Yellow colour pod)
</em>
Form the produced offspring it can be inferred that the allele combination for green colour pod is Gg. Among the four off springs obtained 2/4 are green colour pod and 2/4 are yellow colour pod.
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
