What if the bunnie i wa breeding had the genotype of WW and WWLL. How many generation would I need to wait to get a hort haired black bunny?

Answers

Answer 1

The generation that must be waited for the offspring of the short-haired black rabbit is the second generation with a probability of 6.25% or 1/16

WW white rabbit genotype, ww black rabbit genotype, LL long hair, ll short hair. If the genotype of a WWll rabbit is crossed with a wwLL then:

Parents: WWll >< wwwLL

Gametes: Wl><wL

Filial: WwLl

100% of their offspring will be white with long hair (WwLl)

If we cross two offspring to create a second generation (both WwLl), we get the following punnett squares:

Parents: WwLl >< WwLl

Gametes:  WL, Wl, wL, w   ><   WL, Wl, wL, wl

Second Filial:

WWLL (white with long hair)

WWL (white with long hair)

WwLL (white with long hair)

Wwll (white with short hair)

WWL (white with long hair)

WWll (white with short hair)

Wwll (white with short hair)

Wwll (white with short hair)

WwLL (white with long hair)

WwLl (white with long hair)

wwLL (black with long hair)

wwLl (black with long hair)

WwLl (white with long hair)

Wwll (white with long hair)

wwlL (black with long hair)

wwll (black with short hair)

The phenotypic ratio of the second generation is 9 (white with long hair) : 3 white with short hair): 3 (black with long hair) : 1 (black with short hair)

Which of the following is the correlation coefficient a researcher would most likely obtain between scores on a measure of exposure to media violence and scores on a measure of aggressive behavior?
- 0.80
- 0.00
- 0.30
- 1.00

Answers

A moderate correlation between exposure to media violence and aggressive behavior, with correlation coefficients often falling between 0.30 and 0.80. 0.80 is correct .

It is likely that a researcher would obtain a correlation coefficient between 0.30 and 0.80 between scores on a measure of exposure to media violence and scores on a measure of aggressive behavior. This is because research has consistently found a moderate correlation between exposure to media violence and aggressive behavior. However, it's important to note that correlation coefficients can vary depending on the specific measures used and the population being studied. A correlation coefficient of 0.00 would indicate no correlation between the two variables, while a correlation coefficient of 1.00 would indicate a perfect positive correlation.

Therefore, 0.80 would be the most likely correlation coefficient obtained by researcher.

Propose an explanation for how a single amino acid substitution could cause such a dramatic difference in the final shape of red blood cells

Answers

A single amino acid substitution in a protein can cause a dramatic difference in the final shape of red blood cells through changes in the protein's conformation.

Proteins are composed of a sequence of amino acids and their three-dimensional structure is determined by the interactions between different regions of the protein, such as the hydrogen bonds, electrostatic interactions, and hydrophobic interactions. These interactions help to keep the protein in its specific conformation, which is essential for its function. A single amino acid substitution can alter these interactions and disrupt the protein's conformation. This can lead to changes in the shape and properties of the protein.

In the case of red blood cells, a single amino acid substitution in a protein that is responsible for maintaining the shape of the cell can cause the cell to change shape. For example, a substitution in the protein spectrin, which is a component of the cell membrane, could cause the membrane to be more or less flexible and thus resulting in a change in shape of the red blood cell. This change in shape can affect the mechanical properties of the cell and can have a significant impact on its ability to flow through capillaries and deliver oxygen to tissues.

Answers

Emphysema is a severe form of COPD that can lead to several serious complications, such as alveolar wall breakdown, reduced respiratory membrane surface area and gas exchange, increased vital capacity, hypoxemia, hypercapnia, and respiratory acidosis, and polycythemia Cor pulmonale.

Emphysema is a chronic obstructive pulmonary disease (COPD) that is characterized by the destruction of the alveolar walls and a reduction in the surface area available for gas exchange.

As a result, individuals with emphysema may experience a decrease in vital capacity, which is the amount of air that can be expelled from the lungs after a deep inhalation.One of the most common complications of emphysema is hypoxemia, which is a condition in which the body does not receive enough oxygen.

This can lead to hypercapnia, a condition in which there is too much carbon dioxide in the blood, and respiratory acidosis, a condition in which the blood becomes too acidic. Another complication of emphysema is polycythemia, which is an increase in the number of red blood cells.

Humans are classified into what group of mammals because their developing embryo grows within the mother before a live birth?

Answers

Humans belong to the group of mammals known as placental mammals, because the developing embryo grows within the mother before a live birth.

Placental mammals are any of a group of mammals in which the embryo and later the fetus, is nourished in the uterus by an organ called the placenta. The placenta is an organ that attaches the embryo to the uterine wall and is the site of exchange between the mother’s and the fetus’s blood in order to provide nourishment to the developing fetus.

Placental mammals are the most highly evolved group of mammals and include monkeys, apes, and humans. In contrast to other mammals, such as marsupials whose embryos are nourished in the uterus for a short time before being born, placental mammals develop within the mother until they are fully developed. This prolonged period of development in the mother gives the fetus time to fully develop its organs and to grow to a larger size before birth.

In E. coli the tryptophan operon is controlled by attenuation. The beginning of the Trp mRNA has several codons for Trp in a row. When Trp amino acid is limiting, the mRNA ________?
a. is destroyed and the operon is not transcribed
b. basepairs to itself, allows RNA polymerase to continue transcribing the operon
c. basepairs to itself, blocking RNA polymerase from transcribing
d. attaches to the promotor sequence to activate RNA polymerase

Answers

When Trp amino acid is limiting, the mRNA basepairs to itself, blocking the RNA polymerase from transcribing the operon. So option c is correct.

Attenuation works by causing the mRNA to form a stem-loop structure that is recognized by the RNA polymerase. When the mRNA contains this loop, the RNA polymerase is blocked from transcribing the operon. This blocking mechanism turns off the production of proteins related to tryptophan, such as enzymes for its synthesis and transport, when tryptophan is in short supply.

The loop structure also prevents the mRNA from attaching to the promoter sequence, which normally activates the RNA polymerase. In other words, when tryptophan is limiting, the mRNA does not attach to the promotor sequence and the operon is not transcribed. The result is that the transcription of the tryptophan operon is inhibited when the cell senses that tryptophan is in short supply.

The concept of spontaneous genesis holds that live things could appear miraculously from inanimate matter.

But Pasteur's findings presented evolutionary biologists with a fresh conundrum: if life could only develop from life, how did living things first originate on the planet?

The solution was presented in the 1920s by A.I. Oparin of Russia and J.B.S. Haldane of England, who independently made compelling cases that the origin of life could be explained by a lengthy and gradual process of chemical evolution rather than by the rapid spontaneous generation of complete organisms in a matter of weeks.

Elements  primitive earth

An atmosphere developed when Earth cooled, primarily from gases released by volcanoes. It contained methane, hydrogen sulphide, and ten to 200 times as much carbon dioxide as the atmosphere we are surrounded by today. The Earth's surface began to cool and solidify after roughly 500 million years, allowing water to accumulate there.

A biologist used the radioisotope tritium (3H) to label thymine and the radioisotope carbon-14 (14C) to label uracil. She then incubated a growing bacterial culture with both labeled bases. After five hours of incubation, the biologist extracted polynucleotides from the cells and separated them into three groups, each containing a range of different polynucleotide lengths. The first group contained the shortest polynucleotides. The second group contained polynucleotides of midrange length, and the third group contained the longest polynucleotides. Then she determined the percentage of each radiolabel in each fraction. Her data are summarized in the table above. Which statement represents a reasonable hypothesis that could explain these results?Uptake of 3H label resulted from DNA replication, and uptake of 14C label resulted from transcription.
