Each member of a family of 5 has eye color that is different shade of brown. The fathers eye are a very dark brown, while the mo

Answer:

It is codorminace.

Explanation:

Codorminace is a type of inheritance relationship in which the offspring receive one allele or gene from the father and another gene from the mother and the two allele inherited are not receive rather they are dorminant in the offspring or they are not masked but they are both expressed in the offspring.

From the question, it could be discovered that the offsprings inherit dark brown gene from the father and golden brown from the mother , the two are expressed at they same time and that is why the children shades from light to dark brown.

Radda [10]

Answer:

The correct answer is: Clostridium Tetani.

Explanation:

Clostridium tetani is a Gram-positive bacteria found in soil.

<u>C. tetani may grow and generate </u><u>tetanospasmin</u><u>, a powerful toxin that interferes with </u><u>motor neurons</u><u>, producing </u><u>tetanus</u><u>, if introduced into a </u><u>wound</u>.

Tetanospasmin travels throughout the body via the lymphatic and bloodstream, where it is taken up by different sections of the nervous system. Tetanospasmin inhibits the release of the inhibitory neurotransmitters glycine and gamma-aminobutyric acid at motor nerve terminals in the nervous system. <u>This blockage causes </u><u>extensive motor neuron activation and muscular spasming</u>. These muscle spasms usually start at the top of the body and work their way down, starting about 8 days after infection with lockjaw and progressing to spasms of the stomach muscles and extremities. The muscle spasms last several weeks.

Tetanus toxoid vaccinations, which are often given to children around the world, can inhibit the toxin's activity.

Define embryonic stem cells. Explain the pros and cons of Embryonic Stem Cells
just olya [345]

Answer:

Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells.

Explanation:

 

 Adult Stem Cells  

Embryonic Stem Cells      

Induced Pluripotent Stem Cells      

Pros

Trans differentiate and and reprogramming of these cells is possible but is not well studied

Thought to be less likely to be rejected if used in transplants

Success has already been demonstrated in various clinical applications  

Can maintain and grow for 1 year or more in culture

Established protocols for maintenance in culture

ESCs are pluripotent cells that can generate most cell types

By studying ESCs, more can be learned about the process of development

 

Abundant somatic cells of donor can be used

Issues of histocompatibility with donor/recipient transplants can be avoided

Very useful for drug development and developmental studies

Information learned from the “reprogramming” process may be transferable for in vivo therapies to reprogram damaged or diseased cells/tissues  

Cons

Limitations on ASC ability to differentiate are still uncertain; currently thought to be multi or unipotent.

Cannot be grown for long periods of time in culture

Usually a very small number in each tissue making them difficult to find and purify

Currently there is no technology available to generate large quantities of stem cells in culture

 

Process to generate ESC lines is inefficient

Unsure whether they would be rejected if used in transplants.

Therapies using ESC avenues are largely new and much more research and testing is needed

If used directly from the ESC undifferentiated culture prep for tissue transplants, they can cause tumors (teratomas) or cancer development    

Methods for ensured reproducibility and maintenance, as differentiated tissues are not certain.

Viruses are currently used to introduce embryonic genes and has been shown to cause cancers in mouse studies

The statement above is FALSE.
Glomerular filtration is the process by which the kidneys filter the blood by removing excess wastes and fluid. Glomerular filteration rate [GFR] is a measure of how well the blood is filtereed by the kidney. If the value of a GFR test is too low that indicates that the kidney is not working well.  <span />
