A student creates a simplified model for the Earth's orbit around the sun. The teacher asks the student to refine the model to include the two most important concepts regarding the orbit of the Earth around the sun. Which
modifications should the student make? Select ALL answers that apply.
A)
The student should indicate that inertia keeps the planet in motion once it
is in motion.
B)
The student's model should indicate that the Earth has a moon that also
orbit the planet
The student's model should indicate that the Earth's position is not tilted
as it orbits.
D)
The student' model should indicate that a gravitational attraction occurs
between the sun and the Earth.
E
The student's model should indicate that the Earth's movement speeds up
during the second half of the orbit.

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
