Answer:
The idea of using recycle tires at playgrounds is a concern for some scientists because they contain carcinogenic substances.
Explanation:
Recycle tires are in playgrounds as rubber mulch. This one is on the playground's floor to cushion the impact of any falls that kids may have while playing. The problem with this product is that, as they are old tires cut into little pieces, they still have the tires' toxins such as arsenic, benzene, cadmium, mercury, etc. Exposure to these toxins can cause cancer. This is why some scientists are concerned with this material in areas where kids are exposed to it since they are more vulnerable to carcinogens than adults.

Explanation:
<u>Available data</u>:
- The kernel color in wheat is a continuous trait determined by two additive diallelic genes
- The red kernels are determined by two genes and two dominant alleles (R1R1R2R2)
- The white kernels are determined by two recessive alleles at the same two genes (r1r1r2r2)
- R1 and R2 alleles are dominant over r1 and r2, respectively
