Answer:
It is expected to obtain 576 individuals with normal wings and body with normal hair, 192 with normal wings and hairy body, 192 with vestigial wings and body with normal hair, and 64 with vestigial wings and hairy body.
Explanation:
Since only the wild-type of the offspring cross each other and since the parents have antagonistic phenotypic characters for each gene, all the progeny produced in the F1 is heterozygous with VgvgHh genotype, where
Vg: Normal wings.
eg: Vestigial wings.
H: Body with normal hair.
h: Hairy body.
Once F1 reproduces with each other, the Mendelian proportions 9/16, 3/16, 3/16, 1/16 expected in the F2 generation are produced.
Since in total there were 1024 individuals in the offspring, this amount is multiplied by the expected proportions, giving rise to the mentioned result.

Answer:
<em>B and C.</em>
Explanation:
The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.
In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.
<em>In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.</em>
<em>Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.</em>
Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.
<em>The correct options is B and C.</em>
The EPA under the Toxic Substances Control Act also referred to as the TSCA are responsible for setting rules and regulations regarding polychlorinated biphenyl, PCB. Tina should reference the TSCA to help support her protest against the very toxic chemicals and compounds in PCB.
