Cornelius Agrippa (1486-1535) was a German mystic who practiced a "science" that combined alchemy, magic, mysticism, and astrology. Two of his books are Three Books of Occult Philosophy and On Calling Spirits. Through the writing of Agrippa, Frankenstein becomes very interested in alchemy, which is a pseudoscience whose main object is to find a way of turning base metals into gold. You could say that Frankenstein adapted the thinking of the alchemists and instead of transforming other metals into gold attempted to transform a corpse into a living being.

An interesting story about Agrippa concerns sightings of him after his death:

There were rumors that Agrippa had summoned demons on his death bed, and that a black dog roamed the countryside as his familiar. The black dog appears in tales as Faustus, Mephistopheles, and even as a grim in the Harry Potter series.

In pea plants, purple flowers are dominant to white flowers, and the purple and white alleles are represented with P and p, resp
amm1812

Answer: 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.

Explanation:

Heterozygous means that its genotype has two distinct alleles, i.e. a dominant and a recessive one. So the genotype of the plants is Pp, and each plant has two alleles since<u> they are diploid organisms, which have two copies of each gene. </u>

<u>Each plant produces gametes, which are haploids cells. That is, they only have one copy of each gene (one allele)</u>. So, the gametes produced by Pp have a P or p genotype.  During fertilization, the maternal and paternal gamete are fused to form a diploid zygote where their genotype will have one allele from the father and one from the mother.

By making this monohybrid cross, we cross the gametes of each parent in the punnett square (see picture)

In the offspring, we see one PP genotype (homozygous dominant), two Pp genotypes (heterozygous) and one pp genotype (homozygous recessive). <u>Since we know the P allele is dominant and it codes for purple color, a genotype only needs one P allele to express that phenotype</u>. So Pp and PP organisms are purple, and only pp is white. That means 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.

An organism has a metabolic pathway that is controlled by an inducer through negative regulation. When this organism is grown in
beks73 [17]

Answer:

The inducer will combines with the repressor and inactivates the pathway.

Explanation:

Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.

In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.

Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.
