Introduction:
Blood is an integral part of our circulatory system made up of the cellular components (red blood cells, white blood cells, and platelets) and the plasma. The main functions of the blood include the transport, protection and the regulation. It carries oxygen and nutrients to every cell in the body and in turn, carries back carbon dioxide and other waste products.
It also helps in the transport of the hormones to their target cells. The white blood cells are involved in rendering immunity to our body by fighting against the invading pathogens. The platelets are involved in the process of blood clotting; thus, preventing blood loss. Blood also regulates the pH, temperature and the water content in the cells.

- What did the Cre-lox system used in the Kikuchi et al. 2010 heart regeneration experiment allow researchers to investigate? What was the purpose of the cmlc2 promoter? What is CreER and why was it used in this experiment? If constitutively active Cre was driven by the cmlc2 promoter, rather than an inducible CreER system, what color would you expect new cardiomyocytes in the regenerated area to be no matter what? Why?arrow_forwardWhat kind of organ size regulation is occurring when you graft multiple organs into a mouse and the graft weight stays the same?arrow_forwardWhat is the concept "calories consumed must equal calories burned" in regrads to nutrition?arrow_forward
- You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick. 1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side? 2) What would be the internal (within the embryo) control for this experiment? 3) How can you be sure that the electroporation method itself is not impacting the embryo? 4) What would you do to ensure that the electroporation is working? How can you tell?arrow_forwardDescribe a method to document the diffusion path and gradient of Sonic Hedgehog through the chicken embryo.
