3 Malaria is a tropical disease characterized by severe chills, headache, and fever.
Malaria is caused by protists in the genus Plasmodium. The disease is spread from
human to human when mosquitoes bite an infected person and transfer Plasmodium
sporozoites to another person. Hoping to develop a product that prevents malarial
infection, a scientist researches chemicals that kill different types of organisms. How
might the scientist use a chemical to prevent the transmission of malaria from person
to person?
A. The scientist might develop a chemical that kills either the mosquito that trans-
fers the protist or the protist itself.
B. The scientist might develop a chemical that kills all Plasmodium sporozoites
found in water and food sources.
c. The scientist might develop a chemical that kills the protist after it has been
transmitted from one person to another.
D. The scientist might develop a chemical that treats the more severe symptoms of
malaria, such as chills, headache, and fever.

Before the can be observed by using a transmission electron microscope, cells are sliced into very thin sections. what disadvantage does this procedure present in the study of cellular parts

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
