Animals have a “toolkit” called the that regulates the of the developing embryo.

The answer is: Hox genes; anterior-posterior axis.

Animals have a “toolkit” called the Hox genes that regulates the anterior-posterior axis of the developing embryo. Hox genes are a group of genes that regulate the development of anterior-posterior axis (head-tail axis) of the embryo. They determine the type of structures that should be formed on the given segment.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
