Answer the following question given this paragraph: Hormone levels during the follicular phase, ovulation, and the luteal phase are compared. During the follicular phase, LH and FSH secreted from the pituitary stimulate several follicles to grow. The follicles produce low levels of estradiol that inhibit GnRH secretion by the hypothalamus, keeping LH and FSH levels low. Low levels of estradiol also cause the endometrial arteries to constrict, resulting in menstruation. During the time leading up to ovulation, LH and FSH stimulate maturation of one of the follicles. The growing follicle begins to produce high levels of estradiol, which stimulates GnRH secretion by the hypothalamus. As a result, LH and FSH levels rise, resulting in ovulation about a day later. Estradiol also causes the endometrium to thicken. After ovulation, the ovarian cycle enters the luteal phase. LH from the pituitary stimulates growth of the corpus luteum from the ruptured follicle. The corpus luteum secretes estradiol and progesterone that block GnRH production by the hypothalamus and LH and FSH production by the pituitary. Estradiol and progesterone also cause the endometrium to further develop. Figure 43.15 The ovarian and menstrual cycles of female reproduction are regulated by hormones produced by the hypothalamus, pituitary, and ovaries. Q: What causes the endometrium to thicken during a menstrual cycle? A:
OPTIONS:
- testosterone
- blood
- ovulation
- estradiol

Answer: estradiol

Question: Answer the following question given this paragraph: The Sun and all the objects held by its gravity make up the solar system. Q: The sun and all objects held by it's gravity make up the? A:
OPTIONS:
- milky way
- planet
- atmosphere
- solar system
Answer: solar system

input with options: Answer the following question given this paragraph: Reactivity is how likely an element is to react chemically with other elements. Some nonmetals are extremely reactive, whereas others are completely nonreactive. What explains this variation in nonmetals? The answer is their number of valence electrons. These are the electrons in the outer energy level of an atom that are involved in interactions with other atoms. Let's look at two examples of nonmetals, fluorine and neon. Simple atomic models of these two elements are shown in the Figure below . Q: The number of valence electrons determines variation of what property in nonmetals? A:
OPTIONS:
- permeability
- density
- turbidity
- reactivity
output: reactivity

Q: Answer the following question given this paragraph: In many species, including humans, circadian rhythms are controlled by a tiny structure called the biological clock . This structure is located in a gland at the base of the brain. The biological clock sends signals to the body. The signals cause regular changes in behavior and body processes. The amount of light entering the eyes helps control the biological clock. The clock causes changes that repeat every 24 hours. Q: The amount of what entering the eyes helps control the biological clock? A:

OPTIONS:
- air
- energy
- heat
- light

A: light

input: OPTIONS:
- ambers
- chelicides
- maxillae
- chelicerae Now, answer this question: Answer the following question given this paragraph: Subphylum Chelicerata includes animals such as spiders, scorpions, horseshoe crabs, and sea spiders. This subphylum is [4] predominantly terrestrial, although some marine species also exist. An estimated 103,000 described species are included in subphylum Chelicerata. The body of chelicerates may be divided into two parts and a distinct "head" is not always discernible. The phylum derives its name from the first pair of appendages: the chelicerae (Figure 15.23a), which are specialized mouthparts. The chelicerae are mostly used for feeding, but in spiders, they are typically modified to inject venom into their prey (Figure 15.23b). As in other members of Arthropoda, chelicerates also utilize an open circulatory system, with a tube-like heart that pumps blood into the large hemocoel that bathes the internal organs. Aquatic chelicerates utilize gill respiration, whereas terrestrial species use either tracheae or book lungs for gaseous exchange. Q: Chelicerata are know for their first pair of appendages, also know as what? A:
A:
output: chelicerae

Question: Answer the following question given this paragraph: A food chain is a simple diagram that shows one way energy flows through an ecosystem. You can see an example of a food chain in Figure below . Producers form the base of all food chains. The consumers that eat producers are called primary consumers. The consumers that eat primary consumers are secondary consumers. This chain can continue to multiple levels. Q: What term is used to describe a simple diagram that shows one way energy flows through an ecosystem? A:
OPTIONS:
- water cycle
- food pyramid
- fuel chain
- food chain
Answer:
food chain
