I believe the answer is A) only semantic memories
Answer:
Allele frequency
Normal allele 
Mutant r allele 
Genotype frequency
Homozygous normal bugs 
Homozygous mutant bug 
Heterozygous normal bug with one mutant r allele and one normal allele 
Explanation:
It is given that 99% of the bugs were killed after the spray of pyrethrum. This suggests that 1% of the bugs that were not killed must be homozygous for the mutant type allele "r"
Thus, the frequency of homozygous "rr" species i.e 
From this we can evaluate the frequency of mutant "r" allele.
Thus, 
As per Hardy-Weinberg first equilibrium equation, 
Substituting the value of q in above equation, we get
Thus, the frequency of homozygous normal bug is equal to
As per Hardy-Weinberg second equilibrium equation-
Substituting all the available values we get -
Allele frequency
Normal allele
Mutant r allele
Genotype frequency
Homozygous normal bugs
Homozygous mutant bug
Heterozygous normal bug with one mutant r allele and one normal allele
"Replication" MUST occur before mitosis and meiosis can occur. :)
Complete question:
In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p). Stem length is controlled by another pair of alleles where tall (T) is dominant to short (t). These two allele pairs segregate independently. Suppose you have a pea plant that has purple flowers and tall stems and you wish to carry out a testcross in order to determine its genotype. Complete the predictions using the correct terms.
1. In order to carry out the testcross, you should cross your original pea plant with another pea plant whose phenotype is -------
2. If you examine 100 F₁ plants from the testcross and find that they all have purple flowers with tall stems, you should conclude that the genotype of your original pea plant is -------
3. If you examine 100 F₁ plants from the testcross and find that 44 have purple flowers with tall stems and 56 have purple flowers with short stems, you should conclude that the genotype of your original pea plant is -------
4. If you examine 100 F₁ plants from the testcross and find that 53 have purple flowers with tall stems and 47 have white flowers with tall stems, you should conclude that the genotype of your original pea plant is
-------
5. If you examine 100 F₁ plants from the testcross and find that 23 have purple flowers with tall stems, 26 have white flowers and tall stems, 24 have purple flowers with short stems, and 27 have white flowers with short stems, you should conclude that the genotype of your original pea plant is

B. Detrital, which basically comes from the word “Detritus”, which means dead materials.
