Ms. sung's students were in science lab trying to identify standard biomolecules: carbohydrates, fats and proteins. during the lab experience, assistant principal matthews came in to evaluate their teacher and the learning environment. ms. matthews reacted positively to the fact that the students were conducting a hands-in investigation, but she reacted negatively to the overall classroom environment. take a look at one lab group. justify ms. matthews concern. what procedures should ms. sung have followed before the lab began?

a) provide the appropriate lab equipment to her students. although the students have on lab aprons and goggles, they are not wearing gloves.
b) ms. sung should start each day with a clean lab. before beginning the lab, she should have cleared away all debris and non-required materials. the best way to prevent accidents is to eliminate hazards.
c) she should have checked each student group before letting them begin work as well as monitored each lab station during class. two students should modify their appearance to maximize safety and they should organize their work space.
d) ms. sung should reconsider what is appropriate for the students to be wearing. instead of lab aprons, it would be best if the students wore lab coats as well as gloves. depending on the chemicals being used, they may also need face masks.

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
