2. Read the following statement: Two students in biology wanted to find out which plant required more water, an
annual or a perennial flower. They decided to use a
dandelion as the annual and a rose as the perennial. In
three separate test tubes they placed equal amounts of
water. In the first two test tubes they placed the
dandelion and the rose, leaving the third test tube without
a flower as a control. Before placing the flowers in the test
tubes they cut the stems at an angle. After two days they
recorded the amount of water left in the test tubes.

B. What is the independent variable of the
following scenario?
C. What is the dependent variable of the following
scenario?
D. What is a hypothesis for the following scenario?
E. What is a constant in the following scenario?

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
