Explain how amino acid sequence data can help scientists infer patterns of evolutionary relationships between species. ... A gene's DNA sequence determines the order of amino acids that make up a protein, so changes in the DNA sequence often result in changes in the amino acid sequence as well.

Design an experiment to determine whether the pink flower of petunia plants results from incomplete dominance.

anzhelika [568]

Answer:

To cross petunia plants/lines with pink flowers (F1) which were obtained by crossing plants with red and white flowers (parental generation). The presence of petunia plants with red or white flowers in F2 would evidence that this trait is under incomplete dominance.

Explanation:

Incomplete dominance is a type of relationship in which both alleles are expressed in heterozygous individuals, thereby resulting in a new phenotype. This type of allelic interaction is commonly referred to as 'the dilution of the dominant allele' in heterozygous individuals. Moreover, codominance refers to a type of allele relationship in which both alleles are expressed to an equal degree in heterozygous individuals.

Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other

Sholpan [36]

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.

<h3>What is plasma?</h3>

It is an aqueous solution that is thick in consistency, straw-colored, and somewhat alkaline. Fifty five percent of the blood is formed by it.

It is made up of a variety of organic and inorganic components, including 90–92% water and 6–8% solutes.

It includes fibrinogen, globulins, albumins, a trace quantity of sodium, calcium, magnesium, chloride, bicarbonate, glucose, amino acids, lipids, and other coagulation-related substances.

Plasma's primary function is to transport proteins, hormones, and nutrients to the body's many organs. Additionally, plasma is where cells dump their waste. The plasma then aids in the body's elimination of this waste. All components of the blood are also transported through your circulatory system by blood plasma.
