Compare and contrast qualitative and quantitative data. Provide an example of each to support your
answer.

Answers

Answer:

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings. Quantitative methods allow you to test a hypothesis by systematically collecting and analyzing data, while qualitative methods allow you to explore ideas and experiences in depth.

The main difference between qualitative and quantitative data is that qualitative data is descriptive while quantitative data is numerical. For example, qualitative data are gender, country, city, nationality, etc. while quantitative data are length, width, height, weight, area, speed, age, etc.

Explanation:

The pathophysiology of primary open-angle glaucoma is still largely unknown, although a joint contribution of vascular, biomechanical, and biochemical factors is widely acknowledged. Since glaucoma is a leading cause of irreversible blindness worldwide, exploring its underlying pathophysiological mechanisms is extremely important and challenging. Evidence from recent studies appears supportive of the hypothesis that a “glymphatic system” exists in the eye and optic nerve, analogous to the described “glymphatic system” in the brain. As discussed in the present paper, elucidation of a glymphatic clearance pathway in the eye could provide a new unifying hypothesis of glaucoma that can incorporate many aspects of the vascular, biomechanical, and biochemical theories of the disease. It should be stressed, however, that the few research data currently available cannot be considered as proof of the existence of an “ocular glymphatic system” and that much more studies are needed to validate this possibility. Even though nothing conclusive can yet be said, the recent reports suggesting a paravascular transport system in the eye and optic nerve are encouraging and, if confirmed, may offer new perspectives for the development of novel diagnostic and therapeutic strategies for this devastating disorder.

WHAT HAPPENS TO OUR BODIES WHEN WE EXERCISE?

What is happening to her circulatory system?

When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the FOOD to produce ENERGY) more faster than they would normally, so the demand for OXYGEN and GLUCOSE is increased.

As the muscles are performing cellular RESPIRATION quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their CO2 (products of cellular respiration are CARBON DIOXIDE and WATER) so the HEART is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.

What is happening to her breathing system?

{Relates to explanation given} The requirement for oxygen is increased so now the respiratory system (in particular the LUNGS) have to work harder and faster to take in more oxygen and to exhale more CO2, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of DIFFUSION is increased.

Many factors affect rigor mortis, such as the type of clothing the person was wearing. Experts from different sciences agree that the definition of death is the end of life. Blowflies are one of the first insects to arrive at a dead body and are very useful in determining the time of death. Livor mortis refers to the color of a dead body. The only two manners of death are natural death and homicidal death. Mechanism of death describes what has occured in the body to cause death. The presence of drugs in a corpse cannot be determined by a chemical analysis of larvae found feeding on the body. In the first 12 hours, a dead body cools about 1 degree F per hour. Within minutes of a death, certain insects are attracted by the smell of the first stages of decomposition. The Body Farm is a fictional account of the work of a country coroner.

Answer:

- Many factors affect rigor mortis, such as the type of clothing the person was wearing. True

- Experts from different sciences agree that the definition of death is the end of life. True

- Blowflies are one of the first insects to arrive at a dead body and are very useful in determining the time of death. True

- Livor mortis refers to the color of a dead body. True

- The only two manners of death are natural death and homicidal death. False

- Mechanism of death describes what has occured in the body to cause death. True

- The presence of drugs in a corpse cannot be determined by a chemical analysis of larvae found feeding on the body. True

- Within minutes of a death, certain insects are attracted by the smell of the first stages of decomposition. True

- The Body Farm is a fictional account of the work of a country coroner. False

Explanation:

Death refers to the permanent cessation of the biological activities in an organism as a whole. Rigor mortis refers to a recognizable sign of death, which is caused by different changes in the muscles after death. Blowflies are insects that can be attracted by the smell of dead and decomposing bodies because they need to identify warm-moist and protein-rich sources to develop their eggs. Livor mortis is the red/blue/purple discoloration in the body skin after death. The manners of death can be divided into 1-accidental, 2-natural, 3-suicidal, 4-homicidal, and 5-undetermined. The mechanisms of death refer to the specific physiological derangements that can lead to the cessation of life (e.g., a heart attack), whose understanding can be essential to elucidate a criminal case. The presence of drugs in a dead body can be determined by an autopsy. The rate at which a dead body cooling depends on the relationship between the body temperature and environmental temperature (e.g, elevated body temperatures and cool environmental conditions are known to increase this value). A body farm can be defined as a research facility where the decomposition of dead bodies can be examined.

In a haplodiploid mating system, how can the coefficient of relatedness between two sisters be 0.75 (75%)? Females are haploid, and they pass on 100% of their genes, whereas males are diploid and pass on 50% of their genes, meaning that the coefficient of relatedness is 0.75. Females can reproduce asexually, meaning they produce clones, and those clones share on average 75% of the genes of their sisters. If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes. Male and female bees are both diploid. The males contribute 100% of their genes to their offspring, and females contribute 50%. Therefore, each female offspring shares 75% of her genes with her sister siblings on average.

Answers

Answer:

If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes

Explanation:

Haplodiploidy is a type of sex-determination system where males are haploid (i.e., they contain only a set of chromosomes 'n') and develop from unfertilized eggs, whereas females are diploid (i.e., they contain two complete sets of chromosomes '2n') and develop from fertilized eggs. The bees show this haplodiploid system of sex determination, which is quite common to many hymenopterans. In bees, workers and queens are diploid (2n) females and contain 32 chromosomes, a set of 16 chromosomes is contributed by the queen's egg, and another set of 16 chromosomes is contributed by the drone sperm (16 + 16 = 32 chromosomes). On the other hand, drones are haploid (n) males and contain only one set of 16 chromosomes, which is exclusively contributed by the queen's egg.
