Answer:
C Biology
even though the correct answer is ecology, ecology is a branch of Biology
Explanation:
The study of how food interacts with genes is known as Nutritional Genomics, that encompasses nutrigenomics, which explores the effects of nutrients in the genome, proteome and metabolome, as well as nutrigenetics, whose main goal is to elucidate the effect of genetic variations on the interaction between diet and disease.
Dissolved O2 conc. in flask with algae will be higher since photosynthesis produces O2.
IAIARr is the genotype of the mother.
<h3><u>Explanation</u>:</h3>
The blood groups are the heredity characteristics of the individual which governs what antigen will be present in blood and what antibody will be present in the blood plasma.
The blood group has the genetic characteristics where A and B are dominant characters and O is the recessive character. Co Dominance is seen in case of blood grouping. Similar characteristics is seen with Rh character too where Rh positive is the dominant character and Rh negative is recessive.
The father has both the recessive characteristics. So he needs to be genetically homozygous which means that he has genetic setup of IoIo and rr.
Two child born has character of A blood group and rh positive, but the other child is A blood grouped and rh negative.
So the mother ought to be heterozygous with respect to Rh group, but she is homozygous with respect to blood group.
So her genetic setup is IAIARr.
Answer: C. Black snakes will not prey on cane toads in areas where cane toads have been present for 40–60 years.
Explanation:
Cane toad secret a toxin called bufotoxin which is a defense mechanism against predators. These defense mechanism is capable of killing black snakes if they eat cane toads. Within a period of 40 to 60 years, the black snakes in these area will be aware of the presence of a toxin capable of killing them in cane toads and will not prey on them. This phenomenon is termed learned behavioral adaptation.
