7. two groups of scientists designed a study to determine if obesity was more common in some families than others. body mass index, or bmi, was used as an indication of obesity. bmi is a measure of a person's weight that is factored by his or her height.

the scientists calculated and recorded the bmis of 50 members within each of five extended families. the results were broken down into four categories: obese, overweight, normal, and underweight. the data from this study is presented in the graph below.

upon examining the data, the two groups of scientists came to two different conclusions. scientists in group x concluded that obesity was more common in some families due to inherited traits. scientists in group y concluded that obesity was more common in some families because they have similar eating habits, which are learned behaviors.

what is the best explanation for the different conclusions?
a) only scientists in group y correctly interpreted the data.
b) the data clearly shows that obesity is not linked to heredity or behavior.
c) people have different points of view that influence how they interpret data.
d) only scientists in group x correctly interpreted the data.

~~16. while watching a special on animals, brianna discovers that hares tend to lose heat through their ears. based on this and what is known about surface-to-volume ratios, propose an explanation as to why hares that live in hot climates (such as the desert) have large, extended ears

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
