What do we know about heredity and sickle cell disease?
Sickle cell disease is the most common inherited blood disorder in the United States. Approximately 100,000 Americans have the disease.

In the United States, sickle cell disease is most prevalent among African Americans. About one in 12 African Americans and about one in 100 Hispanic Americans carry the sickle cell trait, which means they are carriers of the disease.

Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.

In people with sickle cell disease, abnormal hemoglobin molecules - hemoglobin S - stick to one another and form long, rod-like structures. These structures cause red blood cells to become stiff, assuming a sickle shape. Their shape causes these red blood cells to pile up, causing blockages and damaging vital organs and tissue.

Sickle cells are destroyed rapidly in the bodies of people with the disease, causing anemia. This anemia is what gives the disease its commonly known name - sickle cell anemia.

The sickle cells also block the flow of blood through vessels, resulting in lung tissue damage that causes acute chest syndrome, pain episodes, stroke and priapism (painful, prolonged erection). It also causes damage to the spleen, kidneys and liver. The damage to the spleen makes patients - especially young children - easily overwhelmed by bacterial infections.

A baby born with sickle cell disease inherits a gene for the disorder from both parents. When both parents have the genetic defect, there's a 25 percent chance that each child will be born with sickle cell disease.

If a child inherits only one copy of the defective gene (from either parent), there is a 50 percent chance that the child will carry the sickle cell trait. People who only carry the sickle cell trait typically don't get the disease, but can pass the defective gene on to their children.





Sickle Cell Disease
An inherited disease in which the red blood cells have an abnormal crescent shape, block small blood vessels, and do not last as long as normal red blood cells. Sickle cell anemia is caused by a mutation (change) in a gene.

Mendel performed a cross between individuals heterozygous for three different traits: green versus yellow seeds (green is dominant), red versus white flowers (red is dominant), and green versus yellow pods (green is dominant). what fraction of the offspring would have been expected to have green seeds, red flowers, and green pods?

Answers

Probability of Green seed * Red flowers * Green pods

3/4 * 3/4 * 3/4 =27/64

The fraction of offspring expected to have green seeds, red flowers, and green pods would be 27/64.

Assuming that the seed shape, flower color, and pod color are represented by A, B, and C alleles respectively.  

Since the parents involved in the cross are heterozygous for each trait, their genotypes would be AaBbCc each.

                 AaBbCc     x     AaBbCc

See the attached image for the Punnet's square analysis of the cross that results in the offspring with the phenotypic ratio.

The proportion of the offspring with parental phenotypes is 27/64.

Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and __________.

Answers

The answer would be: cell lysis due to the effect of osmotic pressure
Cell membrane is important for microorganism because of it separate things outside cells and inside cells. This way, the cell can keep electrolyte and other useful things like carbohydrate and proteins. The cells also dump toxins and dangerous chemical that it produce outside the membrane so it won't damage organs inside the cells. 
Final answer:

Bacitracin inhibits the movement of peptidoglycan precursors, therefore interfering with cell wall synthesis and leading to weak cell walls. This results in bacterial cells being more susceptible to osmotic lysis, causing them to rupture due to a water concentration imbalance.

Explanation:

Bacitracin is an antibiotic that inhibits the movement of peptidoglycan precursors from the cytoplasm to the cell wall, interfering with cell wall synthesis in bacteria. Consequently, this results in the creation of weak cell walls and renders the bacterial cells more susceptible to osmotic lysis. This condition refers to the rupture or disintegration of the cell due to an imbalance in water concentration through the cell membrane. Osmotic lysis may occur in bacteria if too much water moves into the cell, causing it to burst. Essentially, bacitracin creates an environment in which it is difficult for bacteria to maintain their cellular structure, hence aiding in their elimination.

This is a dna fingerprint exhibiting samples from a victim, two suspects, and the crime scene. which of these dna fragments is common to both the victim and suspect 1? question #9 this is a dna fingerprint exhibiting samples from a victim, two suspects, and the crime scene. which of these dna fragments is common to both the victim and suspect 1? question #9 a b c d e

Answers

The question shows the results of a gel electrophoresis, which shows DNA fragments of the victim and two suspects, suspect 1 and suspect 2. A comparison of the five DNA fragments of the victim, A to E, reveals that the victim and suspect 1 both have the DNA fragment b.

A visual comparison of the gel electrophoresis results should reveal that Suspect 1 has a DNA fragment that matches victim DNA fragment B.The visuals can be seen in the attachment.

Final answer:

Without a visual reference, it's not definitive to say which DNA fragment is common between the victim and suspect 1. However, in DNA fingerprinting, common fragments are visible as aligned bands in the same position in both samples.

Explanation:

The process of identifying the DNA fragments in a sample is known as DNA fingerprinting. Without an image or graphical representation of the DNA fragments from the question, it's impossible to definitively say which fragments are common between the victim and suspect 1. However, in a typical DNA fingerprinting procedure, common fragments would be represented as bands in the same position in both the victim's and suspect 1's DNA samples.

This procedure is based on the concept of gene loci where each individual has unique DNA sequences. The comparison, in this case, is done by looking at the bands' positioning in each sample. If multiple bands, or even a single significant band, aligns between the victim and suspect 1, there could be a link suggesting that suspect 1 might be related to the crime scene.

Death usually occurs within hours upon poisoning with usual symptoms of gastrointestinal such as nausea, vomiting, diarrhea. Others experience burning, tingling sensation and numbnes. In large dose of poisoning, motor weakness can be expected some hypotension, bradycardia, arrhythmia. Treatment is usually supportive and patients must be closely monitored.
Final answer:

Woman's bane or wolf's bane refers to Aconitum, a plant that produces a deadly poison. This can be related to Batesian mimicry, where a highly toxic species resembles a less toxic one, discouraging predators.

Explanation:

The term Woman's bane or wolf's bane is another name for the plant Aconitum, which produces a deadly poison. This fits under the concept of Batesian mimicry because it involves a highly toxic species (Aconitum) that resembles a lower toxic one. Batesian mimicry is when a harmless species imitates the warning signals of a harmful species to fend off predators. For instance, a plant like Aconitum might look visually similar to other less toxic plants, tricking potential predators into avoiding it due to the perceived risk of poisoning.

Why do you think there are earthquakes in mid-America where there are no known fault lines?

Answers

Earthquakes are mainly known to occur at plate boundaries where plates converge, diverge or slide past each other. Earthquake activity sometimes accompany volcanic eruptions but these too are concentrated around some plate boundaries (convergent, divergent). 

Smaller earthquakes are known to occur in intra-plate regions, away from margins. These occur simply because of stresses being built up in rocks. The crust is solid and rigid and it floats on the mantle which is a curved surface like the crust. 

A large tract of land is purchased by a commercial agricultural company. The land is cleared of its native flora, and a single crop is planted instead. What is the effect of this action?

Answers

Final answer:

Clearing land for a single crop in commercial agriculture can result in the loss of biodiversity, changes in rainfall patterns, and increased vulnerability to pests and diseases.

Explanation:

When a large tract of land is purchased by a commercial agricultural company and cleared of its native flora to plant a single crop, it has several effects. One of the main effects is the loss of biodiversity as native plants and animals are displaced. This type of agricultural practice can also lead to changes in rainfall patterns and frequency and contribute to deforestation. Additionally, relying on a single crop can make the land more vulnerable to pests and diseases.

Answers

the earliest living organisms were microscopic bacteria, which show up in the fossil record as early as 3.4 billion years ago. As their numbers multiplied and supplies of their chemical fuel were eaten up, bacteria sought out an alternative energy source. New varieties began to harness the power of the sun through a biochemical process known as photosynthesis—a move that would ultimately lead to simple plants and which opened the planet up to animal life.

How did darwin use the fossil record to support descent from common ancestors and natural selections?

Answers

According to Darwin related organisms have common ancestors. As adaptive characteristics become more widespread in a population through successive generations, the result is natural selection. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. They serve as important evidence of evolution since they show that life on earth was once different from what exists on earth today.
