Answer: If crossing over did not occur during meiosis, there would be less genetic variation within a species. ... Also the species could die out due to disease and any immunity gained will die with the individual. Two types of gametes are possible when following genes on the same chromosomes. If crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes.

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.
Because of strong adhesion , a property of water which directly contributes to capillary action.
<h3>What is adhesion and what is capillary action?</h3>
- See in the plants there is always a need of cohesion and adhesion as we all know already which is the only way water can be up to the plants aerial parts.
- Though there are two more ways called transpiration pull and root pressure theory.
- Cohesion is the property of water which depicts its attraction properties.
- Adhesion is the property of the water which mean water molecules can stick to other particles or molecules.
- And is the same reason that is adhesion which gives a boost to capillary action.
