These substances can be chemicals, bacteria, parasites, etc. All sorts of pollution make go to the water directly or indirectly.

Answer:
There are several hypotheses as to why Earth's climate changed: an ice age and a meteor collision are two. Regardless of why the climate changed, dinosaurs could not adapt to a new environment to avoid extinction. Mammals did not become a dominant species on Earth until the extinction of dinosaurs.
Answer: In this lab we explored the relationship between genotype and phenotype with a virtual experiment testing the hypothesis “if either parent mouse passes a dominant allele, then the offspring will have black fur. We used “B” for the dominant allele (black fur) and “b” for the recessive allele (white fur). Step 1-3 We made predictions for each step by filling in the shaded boxes with the alleles of each parent in a punnett square then breeding ten offspring mice using a data table to record the number (out of 10) and a percentage (out of 100%) of each phenotype in the rows”Simulated Number” and “Simulated Percentages.” Step four was to cross a female with white fur and a male with black fur. The next part was recording and inserting the number of offspring with each fur color, then converting these numbers to percentages into our data table. Step 5 was determining the genotypes of the parents in the test cross.
