Red-green color blindness is a sex-linked recessive traits in humans. Two people with normal color vision have a color blind son. What are the genotypes of the parents?

In mice, apricot eyes is recessive to black eyes. Tail length is governed by another gene, linked to the eye color gene. Long tails is dominant to short tails. To determine the distance between the two genes, a double heterozygote is mated in a testcross and the classes of progeny produced were as follows:

Apricot eyes, Long tails 33

Apricot eyes, Short tails             20

Black eyes, Long tails                17

Black eyes, Short tails                30

Determine the map distance between the two genes

Description

The Home pregnancy test strips are classified under “Rapid immunological tests”; the strips are a form of a solid phase immunoassay. It follows the basic immunological principles of binding of an antigen to an antibody.

Instructions

Describe what an immunoassay is. Describe how this strip works. Describe what the antigen in this test is, and how this antigen binds only to its antibody and nothing else. What is the region of an antigen that reacts with an antibody called? What happens during the test? There are two lines on the strip-what do these two lines indicate, and what does the change in color of the control line validate? Sometimes, using this test too early in the pregnancy will not yield an accurate test result. Why would this be? What is the earliest point in pregnancy that such a test can be used reliably? Rapid tests have a shelf life leading to inaccuracies past the “use by” date. What would be the reason for this “use by” limit? Which the materials could cause inaccurate results?

Looking for a little insight, Thanks in advance

David defeated Goliath (according to the bible): triumph of the weak against the strong and/or the struggle between faith and science. Please search first, what type of vision is present in a person that has a tumor compressing the optic chiasm.

Is there a possibility (moving a little bit away from faith) that Goliath suffered from gigantism (a hypophyseal tumor) producing an excess of growth hormone and compressing the optic chyasm and could not see where David was??

You get a phone call that changes your life: your child or a relative's child has in a car accident. He has been taken to the hospital, but is unable to move his legs. Many times, having as much knowledge as possible on a medical topic better prepared you to talk to medical professionals. This is we will dig deeper into learning about our body systems. this discussion i will explore spinal cord injuries and their prognoses. You will need to conduct research and document evidence.

1. Describe the process of nerve healing in peripheral nerves and the difference between central and peripheral nerves.
2. Explain how the nervous system grows with us and how that supports it's function.
3. Suggest a reason why most neurons are amitotic.
4. Explain why neurons very rarely become cancerous.
5. Express how the symptoms mentioned in the letter demonstrate the connection between anatomy and physiology, based on injury location.
6. Provide insight into new research, perhaps with stem cells, and describe why specific new research may , or may not , be the answer to cure these injuries.
7. Discuss why medical professional should never guarantee an outcome with a nervous tissue injury.

A missionary couple, living in West Africa bought their 4-year old son to the Emergency room as he had fever and a pinkish rash has been developing on his hands and feet at first then it spread to both arms and legs. There are no other symptoms that the child feeling very fatigued. 1. This disease is most likely caused by what bacteria? Name the disease. 2. How would epidemiology assist you in finding the sources of this illness? 3. The boy had all of his vaccines so why does he have such a disease? 4. What course of treatment would you order and why? What type of antibiotic would you use and why? 5. What are the virulence factors for the causative agent? Explain the mode of action of these factors

A white-eyed Drosophila female would have the genotype:

Cinnabar eyes is a sex-linked recessive trait in Drosophila. If a cinnabar female is mated with a normal male, what percentage of the F1 males will have cinnabar eyes?

Gene S controls the sharpness of spines in a species of cactus. SS and Ss individuals have sharp spines and ss individual have dull spines. A second gene determines whether the cactus has spines at all. NN and Nn individuals have spines and nn individuals have no spines.

What is the difference between microevolution and macroevolution?

1. Microevolution is proven fact, and macroevolution is just a guess (a theory).

2. Microevolutionary processes are always faster than macroevolutionary processes.

3. Microevolution describes changes in allele frequencies within populations/species; macroevolution describes processes occurring above the species level.

4. Microevolution is about small changes, and macroevolution is about big changes.

What is the proper relationship between the terms “fact” and “theory”, as they are used in science?

1. Theories are guesses, but if they turn out to be correct, they become facts.

2. A hypothesis, after passing many tests against facts, becomes a theory.

3. Many facts, when added together, become a theory.

4. Theories provide systematic explanations of diverse classes of facts.

A boy falls off his bike and skins his knee. In thinking about the structure of the lower leg and specifically the knee, it quickly becomes apparent that the knee is a good example of a location in the body where many types of tissues work together to perform a function – in this case movement. Identify at least four different types of tissues that are present in the lower leg and knee area. You must include at least 3 of the 4 categories (i.e. connective, epithelial, nervous, muscle) of the tissues you select. For each tissue you identify include the following information: name of tissue tissue category function of that tissue in the lower leg and knee region
