I think that the bright light would be the "stimulus" and the pupil constricting would be the "response".
The question is incomplete. The complete question is:
Question: Select the correct statement about the special fetal blood vessels.
A The umbilical vein becomes the ligamentum teres.
B The distal parts of the umbilical arteries form the superior vesical arteries.
C The hepatic portal vein forms from the umbilical artery.
D The fossa ovalis becomes the f
oramen ovale.
Answer:
C) The umbilical vein becomes the ligamentum teres.
Explanation:
After birth, many vascular changes occur in the newborn child as the pulmonary, renal and digestive systems start functioning. As the umbilical cord is tied off and severed, the blood does not flow through the umbilical arteries. The umbilical vein in the child collapses but remains as the ligamentum teres. Ligamentum teres is a round ligament and serves to attach the umbilicus to the liver. It is present in the free border of the falciform ligament of the liver.
Answer:
Reforestation and afforestation
Explanation:
Reforestation is planting trees to restore the forest area while the process of afforestation refers to plantation on a new barren land that is devoid of ant trees. Trees reduce the air pollution by taking in carbon dioxide for photosynthesis and releasing oxygen gas in air. Hence, reforestation and afforestation are effective strategies to reduce the air pollution.
Yes, but some micro organisms that are like that are either too small for scientists to always spot, plus some of them don't just eat the cancer cells. They continue on. You have to realize that decomposes eat and eat on at decaying bodies to the extent that they are just a skeleton. Injecting micro organisms like that into the body is highly dangerous and fatal. A person could slowly die of blood loss if scientists and doctors don't figure out where the organism is and how to get it out of the body. That organism would be in the blood stream making it harder to get out than a tapeworm, that usually hang out in the stomach and taking medication can get them out.
So I would not suggest you tamper with decaying animals. You could get sick without gloves.
Answer:
Explanation:
The relative ages of rocks are important for understanding Earth's history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
