A cell membrane is compared to a window screen because of its translucent properties. Like it allows oxygen to come through or it resists invader who tries to come into the cell.
Your answer is Cell membrane.
Upon crossing BB with bb, we will get a hybrid of Bb.
- Codominance is a phenomena in genetics where two alleles (different forms of the same gene) express themselves equally in an organism. As a result, characteristics linked to each allele are shown at the same time.
- The MN blood group system in humans is an illustration of codominance. M and N alleles control the MN blood type. Red blood cells from people who are homozygous for the M allele carry a surface molecule known as the M antigen. On their red blood cells, those who are homozygous for the N allele contain the N antigen. A heterozygote is a person who carries both antigens.
- (a) Genotype of blue scales fish will be BB.
- (b) Genotype of blue scales fish will be bb.
- (c) Genotype of blue scales fish will be Bb.
So, in this case B and b alleles will express equally.

Five cellular targets of antibiotics were exploited withinside the improvement of antimicrobial drugs: cell wall synthesis, protein , ribonucleic acid , (DNA) , and middleman metabolism.
<h3>How do antibiotics acts as resitance?</h3>
The principal mechanisms of resistance are: proscribing uptake of a drug, amendment of a drug target, inactivation of a drug, and lively efflux of a drug. These mechanisms can be local to the microorganisms, or received from different microorganisms.
In principal, there are 3 principal antibiotic objectives in bacteria: The cell wall or membranes that surrounds the bacterial mobileular. The machineries that make the nucleic acids DNA and RNA. The equipment that produce proteins (the ribosome and related proteins).

C 1650 Because you have to factor in the difference of BC and AD. you must get 1200 BC to 0 first, and then go to 450, therefore getting 1650
