Answer:
<em><u>Lizard</u></em><em><u> </u></em><em><u>is a poikilothermic animal </u></em><em><u>because</u></em><em><u> </u></em><em><u>lizards</u></em><em><u> </u></em><em><u> </u></em><em><u>are</u></em><em><u> </u></em><em><u>those</u></em><em><u> </u></em><em><u>animals that do not require a fixed body temperature, their temperatures can fluctuate with little to no adverse effects to their overall health. </u></em>
Explanation:
<em>Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. </em><em> By moving in and out of sunlight, reptiles can keep their body temperature at a steady level throughout the day.</em>
An asteroid hitting the earth would cause a lot of dust, ash, and other debris to go into the atmosphere which would block the sun which would cause the temperature to decrease.
Answer:
oxytocin
Explanation:
Oxytocin is a hormone naturally produced by our body to generate contractions of the uterus during labor and the release of milk during breastfeeding. It was synthesized in the laboratory and thus became a very useful medication that can help save lives if correctly indicated.
This hormone can also be used to initiate labor when it does not occur naturally, and can regulate contractions when they are not effective and it is diagnosed that labor is not progressing properly.
In addition, it can also be used to contract the uterus after childbirth or abortion when bleeding is very abundant, preventing bleeding that could lead to loss of the uterus and even death if not properly controlled.
