I’m not exactly sure what your experiment is, but I can make a few guesses. Maybe a substance is being mixed with the baking soda and breaking it up can help with dissolving. Or maybe the baking soda must fit through a small opening and cannot be lumpy. Please message me or comment under my response with further detail if u still need help.

Part A
quester [9]

Answer:

0.2 (or 20%)

Explanation:

The allele frequency can be calculated by counting how many times an allele appears in a population and then by dividing this number by the total number of alleles of the gene. In this case,

- Genotype BB = 30 moths >> 60 copies of the B allele

- Genotype Bb= 12 grey moths >> 12 copies of the B allele and 12 copies of the b allele

- Genotype bb= 3 white moths >> 6 copies of the b allele

The total number of copies of the gene is:

Dominant (B) allele = 60 (BB genotype) + 12 (Bb genotype) = 72 B alleles

Recessive (b) allele = 12 (Bb genotype) + 6 (bb genotype) = 18 B alleles

Then, 72 + 18 = 90 alleles  

Allele frequencies:

Dominant (B) allele = 72/90 =  0.8 (or 80 %)

Recessive (b) allele = 18/90 = 0.2 (or 20%)

Difference in prophase one and prophase two in meiosis
Dmitrij [34]

Answer:

The main difference between prophase I and II is that during prophase 1, the pairing of homologous chromosomes or the synapsis allows the non sister chromatids to cross over at chiasmata, leading to genetic recombination between chromosomes. During prophase II,synapsis does not occur; hence, no genetic recombination takes place between the chromosomes

During Prophase I the Centrosome is duplicated during the interphase, which is a process prior to prophase while in Prophase II, the Centrosome is duplicated during the prophase II due to the lack of an interphase.

Instill refers to the action of pouring or introducing a liquid drop by drop on a mucosal surface or inside a canal or organic cavity, for therapeutic purposes. The most used instillations are: conjunctival, nasal, paranasal, atrial, laryngeal, tracheal, bronchial, bladder and urethral. The instillation can be carried out with the help of a simple common dropper or with an instrument called an instillator, which consists of a probe with a widened end and a syringe with a screw plunger; by activating the screw, the medicine is introduced drop by drop.
