Describe the process used for harvesting adult stem cells

Biology
1 answer:
Tomtit [17]3 years ago
5 0

Answer:

Stem cell is taken either from bone marrow or from the blood directly

Explanation:

Stem cells are derived from two locations primarily a) Bone Marrow and b) Blood

The first step in this process is to remove the stem cell from its parent location and it is done in the following ways –  

A) For deriving stem cell from blood – A drug with growth factor s is injected. Here no anesthesia is given to the patient. The growth factors leads to the movement of stem cells from bone marrow into the bloods. Blood with stem cells is taken out from the veins and filtered through the apheresis machine.  

B) From Bone marrow – Bone marrow is removed from the pelvic bone through a needle and prepared for transplantation.

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d). A pigment-eye
Ivenika [448]

Answer:

PpDD and PpDd

Explanation:

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).

The <u>possible genotypes of a pigment-eyed, dimple-chinned person</u> would be  PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.

The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.

In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).

<em>Hence, the genotype of the father is now limited to </em><em>PpDD</em> <em>and </em><em>PpDd</em>.

elena55 [62]
Hello.

M*Cp*(T’-Tf)=MCp(T'-T)

M*= Mass of Water. ; M= Mass of ice.

Cp*= Specific heat of water

Cp= Specific heat of ice

T= Temp. Of Ice

T'= Temp. of water

Tf= Equilibrium Temp.
