Q: Answer the following question given this paragraph: 15.5 Echinoderms and Chordates Echinoderms are deuterostome marine organisms. This phylum of animals bear a calcareous endoskeleton composed of ossicles covered by a spiny skin. Echinoderms possess a water-based circulatory system. The madreporite is the point of entry and exit for water for the water vascular system. The characteristic features of Chordata are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Chordata contains two clades of invertebrates: Urochordata (tunicates) and Cephalochordata (lancelets), together with the. Q: What kind of system do echinoderms possess? A:
Answer: water-based circulatory

Answer the following question given this paragraph: A common sign that labor will be short is the so-called "bloody show. " During pregnancy, a plug of mucus accumulates in the cervical canal, blocking the entrance to the uterus. Approximately 12 days prior to the onset of true labor, this plug loosens and is expelled, along with a small amount of blood. Meanwhile, the posterior pituitary has been boosting its secretion of oxytocin, a hormone that stimulates the contractions of labor. At the same time, the myometrium increases its sensitivity to oxytocin by expressing more receptors for this hormone. As labor nears, oxytocin begins to stimulate stronger, more painful uterine contractions, whichin a positive feedback loopstimulate the secretion of prostaglandins from fetal membranes. Like oxytocin, prostaglandins also enhance uterine contractile strength. The fetal pituitary also secretes oxytocin, which increases prostaglandins even further. Given the importance of oxytocin and prostaglandins to the initiation and maintenance of labor, it is not surprising that, when a pregnancy is not progressing to labor and needs to be induced, a pharmaceutical version of these compounds (called pitocin) is administered by intravenous drip. Finally, stretching of the myometrium and cervix by a full-term fetus in the vertex (head-down) position is regarded as a stimulant to uterine contractions. The sum of these changes initiates the regular contractions known as true labor, which become more powerful and more frequent with time. The pain of labor is attributed to myometrial hypoxia during uterine contractions. Q: Oxytocin, which stimulates the contractions of labor, is a type of what? A:
OPTIONS:
- metabolite
- inhibitor
- steroid
- hormone

Answer: hormone

input with options: Answer the following question given this paragraph: Photosynthesis changes light energy to chemical energy. The chemical energy is stored in the bonds of glucose molecules. Glucose, in turn, is used for energy by the cells of almost all living things. Photosynthetic organisms such as plants make their own glucose. Other organisms get glucose by consuming plants (or organisms that consume plants). Q: What does photosynthesis change light energy into? A:
OPTIONS:
- electrical energy
- carbon energy
- radiation energy
- chemical energy
output:
chemical energy
