Suppose in a species of petunia, locus A determines petal color and locus B determines whether the petals can express any pigment. At locus A, purple petal color (A) is dominant over yellow petal color (a). At locus B, pigmentation (B) is dominant over lack of pigmentation (b). If an AA BB plant is crossed to an aa bb plant, what is the ratio of purple- to yellow- to white-flowered petunias expected in the F2 progeny?
A. 9:3:4
B. 15:1
C. 9:4:3
D. 12:3:1
E. 9:7

Answers

Answer 1

9:3:4, Although it's not as straightforward as just producing pigment, flower color is the consequence of pigment molecules gathering in cells. The location, type, and quantity of the pigment are all crucial factors.

What genotype determines flower color?

The P locus genotype influences whether flowers are purple or red-pink in hue. PP or Pp individuals have purple flowers, whereas pp people, depending on the genotype at the I locus, have pink or red flowers.

Does a single gene determine the color of a flower?

Mendel came to the conclusion that the color of the pea flowers was governed by a single locus or gene after doing numerous additional tests with cross-breeding subsequent generations of flowers. That gene requires two known components in order to produce two distinct hues.

Answers

Rosalind Franklin produced critical x-ray crystallography data for the modern model of DNA.

The DNA double helix was first conceptualized by British physicist Francis Crick and American biologist James Watson in the early 1950s. In this scientific "marathon," they were the first to reach the finish line, while others like Linus Pauling (who discovered protein secondary structure) were also looking for the right model.

Watson and Crick gathered and analyzed previously obtained data, combining it in novel and illuminating ways, rather than doing brand-new tests in the lab. Rosalind Franklin, a scientist working in physicist Maurice Wilkins' lab, provided them with some of the most important hints about the structure of DNA. Franklin was a master of X-ray crystallography, a potent method for figuring out the structure of molecules. When a molecule, like DNA, is subjected to X-rays in its crystallized form, part of the rays are refracted by the crystal's atoms, creating a diffraction pattern that reveals information about the structure of the molecule.

he chemical equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is shown.

Mg + 2HCl → MgCl2 + H2

Fiona weighs the magnesium and hydrochloric acid before the reaction and finds a total mass of 55 grams. After the reaction, she measures the mass of the products, magnesium chloride (MgCl2) and hydrogen (H2), and finds a total mass of 55 grams again. Does Fiona's data support the law of conservation of matter, and why?

a
Yes, because the mass of the reactants is lower than the mass of the products in her data.
b
No, because the mass of the reactants is the same as the mass of the products in her data.
c
No, because the mass of the reactants is lower than the mass of the products in her data.
d
Yes, because the mass of the reactants is the same as the mass of the products in her data.

Answers

D) Yes, because the mass of the reactants is the same as the mass of the products in her data.

The law of conservation of matter states that matter cannot be created or destroyed, only transformed. This means that the total mass of the reactants in a chemical reaction should be equal to the total mass of the products. Fiona's data supports this law because she found that the total mass of the reactants is the same as the total mass of the products. This suggests that the magnesium and hydrochloric acid were transformed into magnesium chloride and hydrogen, without any loss of mass.

According to the rule of conservation of mass, in a chemical process, mass neither creates nor destroys itself. When coal is burned, for instance, the carbon atom in it transforms into carbon dioxide. Although the carbon atom's shape changes from solid to gas, its mass remains constant. Thus option D is correct.

What law of conservation of matter in chemical reaction?

This implies that the total masses of the reactants and products in a chemical reaction should be equal.

The data collected by Fiona shows that the total masses of the reactants and products are equal, which lends support to this law. This implies that there was no mass loss during the conversion of the magnesium and hydrochloric acid into magnesium chloride and hydrogen.

Therefore, Yes, because the mass of the reactants is the same as the mass of the products in her data.

Question 28 Gatsby's car symbolizes A. the pursuit of wealth through illegal means B. a moral center in the novel C. the emotional turmoil and feelings of the characters D. the growing economic prosperity through industry​

Answers

The correct answer is d. the growing economic prosperity through industry. In F. Scott Fitzgerald's novel The Great Gatsby, Gatsby's car is a symbol of the growing economic prosperity and industrialization of the United States during the Roaring Twenties. The car is described as a "rich cream color, bright with nickel, swollen here and there in its monstrous length with triumphant hat-boxes and supper-boxes and tool-boxes, and terraced with a labyrinth of windshields that mirrored a dozen suns." This description emphasizes the car's wealth and opulence, and suggests that it is a product of the thriving economy of the time.

Gatsby's car also symbolizes the excess and decadence of the era, as it is described as being "swollen" and "monstrous" in its size and extravagance. This reflects the excesses of the time, as many people became wealthy through illegal means, such as bootlegging, and spent their money on lavish parties and extravagant possessions. Gatsby's car, with its "triumphant hat-boxes" and "terraced" windshields, represents this excessive lifestyle.

Overall, Gatsby's car symbolizes the growing economic prosperity and industrialization of the United States during the Roaring Twenties, as well as the excesses and decadence of the era.

If variation in a species was only due to meiosis, how would that limit the evolution of that species?

Answers

Meiosis occurs in a diploid sex cell and results in four cells (gametes). All these four haploid/cell gametes are genetically different from each other. The characters of the parent are distributed at random because

These four arms of chromosomes are randomly distributed in the gametesThese arms are novel lengthwise due to the crossing over that has taken place (see fig below). These variations increase further after the union of gametes during fertilization creating offspring with unique characteristics. Thus, it creates a diversity of life and is responsible for evolution.

Genetic mutation is the primary basis of fresh genes. Without mutation, you will ultimately run out of different gene pairings, which puts that species in a bit of an evolutionary bind. For a species to survive, it has to maintain genetic variety. Less genetic diversity greatly reduces potential adaptations that might boost reproductive success, which increases the likelihood that the species will become extinct due to disease or competition for food or mates.

Dilution is the process of lowering a solute's concentration in a solution. It usually just involves mixing the solution with more solvent, such more water.

A solution is diluted when more solvent is added without increasing solute. The final mixture is thoroughly mixed to make sure that every component is the same.

Gases and vapors diluted in air, for instance, are directly related in the same way. However, it could be more difficult to achieve thorough mixing of gases and vapors.

For instance, a solution has a given salt concentration if 10 grammes of salt (the solute) are dissolved in 1 litre of water (the solvent) (molarity).

Neurogenesis causes the formation of a new generation of nerves that give a psychological impact that gives it a different character.

3. Nucleus uses the mRNA codons and the genetic code to determine the amino acids.

A codon was thought to code for the same amino acid regardless of the organism or source, according to the old theory of the genetic code. The genetic code evolves, it is now understood, and as a result, there are differences in how a codon is translated depending on the genetic source. For instance, it was found in 1981 that the coding system in mammalian mitochondria used codons AUA, UGA, AGA, and AGG differently than the universal code. Stop codons can also be impacted; for example, the universal stop codons UAA and UAG in ciliated protozoa code for glutamine.
