Answer:
b. aaBb x AAbb
Explanation:
According to the information in this question, the trait for magic ability is controlled by two genes, each comprising of two alleles i.e. A,a and B,b. However, to be able to perform magic, a person would need to carry at least one copy of the dominant allele (A and B) on each of the two loci.
Hermione Granger has magical ability but neither one of her parents does. This means that although Hermione can perform magic, none of her parents can. Genetically, it means that Hermione posseses at least one copy of the dominant allele on each of the two loci i.e. her genotype is A_B_.
This is only possible in Hermione if her parents transferred a dominant allele at each loci to her. This means that the possible genotypes for Hermione Granger’s parents are aaBb (no magical ability) x AAbb (no magical ability). See the punnet square attached where the probability of producing offsprings with magical ability is 1/2 or 50%.
Answer: b) organelles must interact with each other to synthesize and transport proteins.
Explanation:
The DNA is a genetic material which is converted into mRNA by the process of transcription in the nucleus. The protein synthesis takes place in ribosomes where the translation of mRNA to protein takes place. The proteins are transferred to rough endoplasmic reticulum for the packaging into membrane structures called as cisternae. The proteins are transferred to the golgi apparatus where they are modified, sorted and packed in vesicles. The vesicles take away proteins outside the cell. In golgi apparatus the proteins are tagged with the aminoacids so that they can be targeted to the particular cell.
Enteropeptidase (also called enterokinase) is an enzyme produced by cells of the duodenum and involved in human and animal digestion.
In accordance with evolutionary theory, male aggression and competition as well as female nurturing develop in childhood as a precursor to their adult responsibilities.
<h3>What is the theory of evolution?</h3>
Within the framework of evolutionary theory, the genesis of the human species is looked at.
According to this theory, people in the current world have qualities that have been passed down through the generations that have been genetically affected and have aided in successful reproduction.
<h3>What key principles guide evolutionary theory?</h3>
According to Darwin's Theory of Evolution, individuals within a species are not all alike, characteristics are passed down through generations, more offspring are born than can live, and only the survivors of the competition for resources will reproduce.
