Inheritance of dibetes mellitus

Hundreds of human diseases are characterized by a genetic component, such as familial breast cancer. These diseases may run in your family and can currently be tested for. Prepare a 200-word report for your own family members about the current state of knowledge on any such diseases and the tests available. Describe the disease,

NEED HELP COMPOSE AN ARGUMENT OF HEALTHY DIET

Discuss why you would or would not choose the reduced-fat product as part of a healthy diet. Include in your discussion the RDA guidelines recommending less than 30% of total calories come from fat.

Supporting or Refuting Taxing High-Fat Foods

In the United States, many states now impose taxes on tobacco to discourage smoking and to help offset the health costs associated with smoking. However, heart disease, which has been linked to a high-fat diet, is the country's number one killer. In addition, more cancer cases in the United States are related to diet than to smo

How do physical and chemical laws limit animal form?

Explain how physical and chemical laws affect a living organism. Also, provide an example of how an organism has evolved to adapt to its physical or chemical environment. Then, answer the following question: Why do you think physical and chemical laws relate functions to structures and vice versa?

Nutritional Caloric Content

In lab, you try burning marshmallows to estimate their caloric content. a) if a large marshmallow, when burned completely, raises the temperature of 1L of water 40 degrees, what is the approximately caloric content measured in nutritional calories (kcal or Cal)? b) how many calories would be required to raise 500g of water 3 de

Genetic Technology

One of the concerns mentioned in the chapter regarding the use of genetic technology centers around privacy issues such as "genetic discrimination." Once we improve our ability to screen the human genome for disease susceptibility, is there any level of testing that should be required by society as a means of reducing health car

Sport supplements are examined.

Companies that sell sport supplements make billions of dollars each year claiming by consuming their products the person can lose or gain weight. Assume the body weight is genetically determined and that any gain or loss in weight will cause the body to activate homeostatic mechanisms to cause the body to return to the original

Sports Srinks, Electrolytes and Hydration.

When it replenishes these nutrients, it can rehydrate and regulate its body temperature. Once the body temperature returns to normal, it can then return to physical activity. Explain why sports drinks might or might not aid in thermo regulation. Why do you think knowing abut thermo regulation can help you make informed choices a

Negative Feedback Loops

How might negative feedback loop explain why people who lose large amounts of weight chain that weight back? Explain the weight cycle in perms of the negative feedback loop. Do you think that weight in humans is regulated by a negative loop? Why or why not? Do you think weight is controlled by a negative feedback loop that is ge

Sickle-Cell Anemia

The text notes that an alternate allele of the hemoglobin gene can cause sickle-cell anemia when a person is homozygous for this allele, but that a person who is heterozygous for the allele actually can derive a benefit from it--protection from malaria. In the United States, 8 percent of African Americans are carriers for the si

Protein Production in Down's Syndrome

People who are born with the condition called Down syndrome generally have three copies of a certain chromosome (chromosome 21), rather than the usual two copies. In 200 words, what can you deduce from this regarding the proteins produced by a person with Down syndrome?

The debate of taxing high-fat foods is included.

In the United States, many states now impose taxes on tobacco to discourage smoking and to help offset the health costs associated with smoking. However, heart disease, which has been linked to a high-fat diet, is the country's number one killer. In addition, more cancer cases in the United States are related to diet than to smo

Physiological changes occur during exercise

Many physiological changes occur during exercise. a. Design a controlled experiment to test the hypothesis that an exercise session causes short-term increases in heart rate and breathing rate in humans b. Explain how at least three organ systems are affected by this increased physical activity and discuss interactions among t

Classifications of Organisms

There are many areas of disagreement about the classification of organisms. For example, there is no consensus about whether the red wolf is a species distinct from the gray wolf or about how many kingdoms are within the domain Bacteria. What difference does it make whether biologists consider the red wolf a species, or into w

Physiological Changes

The human body manifests physiological changes in every organ system throughout the process of eating, from the time a person first anticipates food to the elimination of waste. a) design a controlled experiment where you test the hypothesis that the body's reaction to eating begins before food enters the body. b) descri

What must I do to live forever?

Introduction We know the features of our physical lives that determine they will be finite; they will die. Scripture clearly teaches that a small remnant of people with these bodies will be given new ones that cannot die. Perhaps you have imagined that these future bodies will be so "bionic" as to be unrecognizably amazing in

Categorizing groups of organisms

I have already categorized the following "Groups of Organisms," except for DOLPHINS. Where would it be placed in the problem below? bats monkeys Euglena lemurs sponges amphibians dolphins Ginkgo biloba jellyfish reptiles birds beavers echinoderms tarsiers photosynthetic bacteria a) production of mi

Function of the kidneys in blood pressure control

Evaluation: Blood Pressure Control Sometimes during traumatic injury, the kidneys must take action to regulate blood pressure in order for the individual to survive. When would this action necessary? Explain in detail how the kidneys regulate blood pressure. Some people have high blood pressure. How do the drugs (cal

Classification of Animals in general and humans in particular

Listed below are several characteristics that are used to classify animals in general and humans in particular: a) production of milk for the young (reproductive, physiological) b) high cognitive ability, to reason, to fashion tools (neurological) c) inability to generate carbohydrates by means of photosynthesis (metabolic)

OW TO ASSIST A NON-MEDICAL WORKER IN AN INSURANCE OFFICE

You work in an orthopedic physician's office as a medical assistant and are responsible for filling out insurance forms and following through on denials. You have become friendly with an insurance company representative in the office of an insurance company with whom you regularly submit claims. You are finding that many of th

This job reacts to human evolution.

This job considers the following statements about human evolution. Which are well supported by scientific evidence and which are misconceptions? a. Humans evolved from apes. b. Human evolutionary history is more like a multibranched bush rather than a single unbranched ladder, our species being the tip of one human branch th

Describe the relative shape of three fatty acids.

Since you forgot to label the fatty acid and the only experimental apparatus you have is a freezer how could you tell which one is which, explain? You have three fatty acid in your kitchen but you forgot to label them. They are all the same length (they all have 20 carbons each)One is a saturated fatty acid, the other two yo
