The benefits of consuming the placenta after giving birth by many female mammals.
Introduction:
The word ‘mammals’ is originated from the Latin word ‘mamma’ means ‘breast’. Mammals are covered with fur or hair. The characteristic feature of the mammal is that they feed their babies with milk which is produced by the mother’s mammary glands.
The ‘placenta’ is the temporary organ that is attached to the lining of the uterus during pregnancy. It provides oxygen and nutrients to the embryo and helps in removing other waste products and carbon dioxide. It produces hormones that help to grow and developing baby. It protects the embryo against some infection mostly and specifically bacteria, not against viruses, during the pregnancy. The placenta is connected to the fetus (or embryo) through the umbilical cord.

- 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.

- The following figure is from Caterina et al. The capsaicin receptor: a heat activated ion channel in the pain pathway. Nature, 1997. Black boxes indicate capsaicin, white circles indicate resinferatoxin. You are a chef in a fancy new science-themed restaurant. You have a recipe that calls for 1 teaspoon of resinferatoxin, but you feel uncomfortable serving foods with "toxins" in them. How much capsaicin could you substitute instead?arrow_forwardWhat protein is necessary for packaging acetylcholine into synaptic vesicles?arrow_forward1.
