Decomposer's role is to break down dead food. They basically eat it, then the dead food or the dead animal gets ground into the ground, and makes the soil good. Like worms, or fungi, mushrooms, etc. Rotten fruit is not really wasted because 1) the decomposers eat it, and 2) it makes the soil good
Chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.

Answer:
Scientists argue, re-examine, and consider new explanations to new data
Explanation:
Theories are susceptible to changes and new data can be incorporated into the theory because advances and discoveries are made.Scientific theories are testable and make falsifiable predictions thus, scientists argue, re-examine, and consider new explanations to new data.As additional scientific evidence is gathered, a new scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings.
Although theories are only modified in most cases, when a theory lacks any of the following characteristic they are susceptible to rejection by the scientists. A theory must be observable and repeatable to avoid frauds. Theories should be testeable and make falsifiable predictions with consistent accuracy across a broad area of scientific inquiry. It should also be well-supported by many independent strands of evidence. In addition, having consistency with preexisting experimental results and accuracy in its predictions as in any preexisting theories. All the above features provide room for change in theories over-time.
Short answer:
Dominant alleles/traits mask recessive alleles/traits. If both alleles are dominant, the organism will express that dominant trait. (i.e. RR)
If both alleles are recessive, the organism will express the recessive trait (i.e rr).
If one allele is dominant, and the other is recessive, it typically expresses the dominant trait (i.e.Rr).

I'll take you back a bit just to help you understand the concept.
Genes carry the information that determines traits that you will get. Specific genes are found in specific locations of your chromosome (locus) and they come in two's and the pairs code for a specific trait. However, the pair of genes do not always match and this is what we call alleles.
Alleles are varied forms of genes. For example, you have a Black allele and a Brown allele for hair color, where Black is DOMINANT and brown is RECESSIVE.
We say dominant because it overrides the recessive if the gene has one of each in its pair. What happens then?
Well, the dominant masks the recessive. The recessive does not go away, but the dominant trait just has a greater effect, which cover the recessive trait . So if we have allele pairs that is black and brown, then the hair color would be black.
If the pair of alleles are both brown, then brown will be expressed because there is no black allele to cover it up.
