The abo blood group in humans is controlled by a single locus with three different alleles. homozygosity for la produces type a blood. homozygosity for ib produces type b blood. homozygosity for l° produces type o blood. type ab blood is produced by the genotype la/ib. io is recessive to ia and 1b, thus ia/l gives type a blood and ib/lo gives type b blood. at another locus, the rhesus or rh factor is also used in blood typing. the rhesus locus also has multiple alleles, but these alleles can be classified into two types, positive and negative. rh+ alleles are dominant over rh- alleles. the allele frequencies of these loci are as follows: for the abo alleles: [lo = .65 [ia] = .27 for the rh factor: [rh+] = .7 [rh-) = .3 18. at what frequency will an individual in this population be type "o", rh positive? e. 0.353 a. 0.210 b. 0.0577 c. 0.424 d. 0.384 19. at what frequency will an individual in this population be type "a", rh positive? e. 0.352 a. 0.210 b. 0.057; 3 c. 0.424 d. 0.386 20. the rarest type of blood is type ab rh negative. how many of these will be expected in 1000 individuals? a. 9.0 b. 10.2 c. 1.94 d. 3.89 e. 21.6

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.

Agenetically engineered corn plant is approved for agricultural use. the plant produces pollen that can make its own toxins. these toxins protect the corn plant against pests and no longer require the application of chemical pesticide. what is a likely impact on the farmer of growing such a variety of corn? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
