Answer:

1.) Genotype = Ff

2.) Phenotype = having freckles

3.) Possible Genotypes = FF, Ff, ff

Probability of each Genotype = 25% FF, 50% Ff, and 25% ff

4.) Possible Phenotypes = Freckles and no freckles

Probability of each Phenotype = 75% freckles and 25% no freckles

Explanation:

1.) A genotype is the specific combination of alleles which give rise to a trait. Alleles are represented by the letters (F and f).

Heterozygous individuals have one of each type of allele. Therefore, the genotype of the couple is Ff.

2.) Phenotypes are the trait which the genotypes are expressing. When an allele is said to be dominant (like the F allele), it means that individuals with at least one of these alleles will express the associated trait. Remember, heterozygous individuals have one dominant allele (F) and one recessive allele (f). Because there is at least one dominant allele, the phenotype of the couple is to have freckles.

What is the starch indicator, and how does it change?

slamgirl [31]

Answer:

Starch is a indicator in the iodometric titration and it turns deep dark blue when iodine is present in a solution. The starch under warming condition forms amylose and amyl pectin's which combine with iodine to produce dark blue color. In absence of iodide ion starch indicator is colorless.

Explanation:

Starch is a viable indicator in the titration process because it turns deep dark blue when iodine is present in a solution. When starch is heated in water, decomposition occurs and beta-amylose is produced. Beta-amylose combines with iodine, resulting in a dark blue color change. The iodine-starch test is a chemical reaction that is used to test for the presence of starch or for iodine. The combination of starch and iodine is intensely "blue-black". The interaction between starch and triiodide is the basis for iodometry. In an iodometric titration, a starch solution is used as an indicator since it can absorb the I2 that is released. This absorption will cause the solution to change its color from deep blue to light yellow when titrated with standardized thiosulfate solution. This indicates the end point of the titration. Aside from their basic nutritional uses, starches are used in brewing and as thickening agents in baked goods and confections. Starch is used in paper manufacturing to increase the strength of paper and is also used in the surface sizing of paper. When starch is heated in water, various decomposition products are formed, among which is beta-amylose which forms a deep blue-black complex with iodine. The starch indicator solution must be freshly prepared since it will decompose and its sensitivity is decreased.

Describe the central dogma of molecular biology, briefly describe the processes of transcription and translation.

Otrada [13]

The central dogma of molecular biology describes the two-step process, transcription and translation, by which the information in genes flows into proteins: DNA → RNA → protein. Transcription is the synthesis of an RNA copy of a segment of DNA. RNA is synthesized by the enzyme RNA polymerase.

Which technique could be used to evaluate the primary amino acid sequence of a protein?

Softa [21]

Answer:

Hundreds of proteins have been sequenced by Edman degradation of peptides derived from specific cleavages. Protein Mass Spectrometry is an analytical technique that measures the mass-to-charge ratio of charged particles for determining masses of particles and the elemental composition of a sample of molecules as well as for elucidating the chemical structure of molecules such as peptides. Protein mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.

Which factors are common to both gradualism and punctuated equilibrium? Migration, genetic drift, speciation, and natural select

FinnZ [79.3K]

<span>The factors which are common to both gradualism and punctuated equilibrium are found in the first option - migration, genetic drift, speciation, and natural selection. Both gradualism and punctuated equlibrium go through these 4 phases. Gradualism, as opposed to punctualism, is a theory that proposes that evolution is a process created through gradual changes, as opposed to immediate ones.</span>
