The punnett square represents the dihybrid cross between two pea plants. here r represents the dominant allele for round shape of the seed and r represents the recessive allele for wrinkled shape of the seed. y represents the dominant allele for yellow seed color and y represents the recessive allele for green seed color. both the plants have the heterozygous genotype rryy. what is the expected phenotypic ratio of dihybrid crosses?

The concept of keystone species is controversial among ecologists because most organisms are highly interdependent. if each of the trophic levels is dependant on all others how can we say one is most important

The negative impacts of nonnative species generally outweigh the positive impacts

Aresearcher designed an investigation to test what effect eating different types of food would have on blood insulin levels. she selected 10 male subjects who were all 25 years of age and in good health. the experiment took place over 3 days. at 8: 00 a.m. on each day, the subjects ate a meal consisting of only 1 type of food. they had their blood insulin levels measured after consuming the meal. on day 1 they ate a high fat diet, on day 2 they ate a high protein diet, and on day 3 they ate a high sugar diel what is the independent variable in this experiment? a the age of the subjects b the blood insulin level c the type of food consumed d the time of day the meal was consumed
