input: OPTIONS:
- primordial follicle
- liberated ovum
- secondary ovum
- corpus luteum Now, answer this question: Answer the following question given this paragraph: Following ovulation, the ovarian cycle enters its luteal phase, illustrated in Figure 43.15 and the menstrual cycle enters its secretory phase, both of which run from about day 15 to 28. The luteal and secretory phases refer to changes in the ruptured follicle. The cells in the follicle undergo physical changes and produce a structure called a corpus luteum. The corpus luteum produces estrogen and progesterone. The progesterone facilitates the regrowth of the uterine lining and inhibits the release of further FSH and LH. The uterus is being prepared to accept a fertilized egg, should it occur during this cycle. The inhibition of FSH and LH prevents any further eggs and follicles from developing, while the progesterone is elevated. The level of estrogen produced by the corpus luteum increases to a steady level for the next few days. If no fertilized egg is implanted into the uterus, the corpus luteum degenerates and the levels of estrogen and progesterone decrease. The endometrium begins to degenerate as the progesterone levels drop, initiating the next menstrual cycle. The decrease in progesterone also allows the hypothalamus to send GnRH to the anterior pituitary, releasing FSH and LH and starting the cycles again. Figure 43.17 visually compares the ovarian and uterine cycles as well as the commensurate hormone levels. Q: The cells in the follicle undergo physical changes and produce a structure called a what? A:
A:
output: corpus luteum

Q: Answer the following question given this paragraph: An example of a disaccharide is sucrose (table sugar), which consists of the monosaccharides glucose and fructose ( Figure below ). Other common disaccharides include lactose ("milk sugar") and maltose. Monosaccharides and disaccharides are also called simple sugars . They provide the major source of energy to living cells. Q: What are monosaccharides and disaccharides also called? A:
Answer: simple sugars

Answer the following question given this paragraph: The bonfire from the opening image has a lot of thermal energy. Thermal energy is the total kinetic energy of moving particles of matter, and the transfer of thermal energy is called heat. Thermal energy from the bonfire is transferred to the hands by thermal radiation. Thermal radiation is the transfer of thermal energy by waves that can travel through air or even through empty space, as shown in the Figure below . When the waves of thermal energy reach objects, they transfer the energy to the objects, causing them to warm up. This is how the fire warms the hands of someone sitting near the bonfire. This is also how the sun's energy reaches Earth and heats its surface. Without the energy radiated from the sun, Earth would be too cold to support life as we know it. Q: How does heat travel from the sun to the earth? A:
OPTIONS:
- through sound waves
- through light waves
- secondary radiation from the sun
- thermal radiation from the sun
thermal radiation from the sun

Answer the following question given this paragraph: Algae are like plants mainly because they contain chloroplasts. This allows them to make food by photosynthesis. Algae are important producers in water-based ecosystems such as the ocean. On the other hand, algae lack other plant structures. For example, they don't have roots, stems, or leaves. Also unlike plants, some algae can move. They may move with pseudopods or flagella. Q: Algae are like plants mainly because they contain what? A:
OPTIONS:
- organelles
- cells
- cell wall
- chloroplasts

Answer:
chloroplasts
