Answer the following question given this paragraph: The embryo, which begins as a flat sheet of cells, begins to acquire a cylindrical shape through the process of embryonic folding (Figure 28.14). The embryo folds laterally and again at either end, forming a C-shape with distinct head and tail ends. The embryo envelops a portion of the yolk sac, which protrudes with the umbilical cord from what will become the abdomen. The folding essentially creates a tube, called the primitive gut, that is lined by the endoderm. The amniotic sac, which was sitting on top of the flat embryo, envelops the embryo as it folds. Q: What sac, which was sitting on top of the flat embryo, envelops the embryo as it folds? A:

OPTIONS:
- uterus
- umbilical sac
- epithelial sac
- amniotic sac

Answer: amniotic sac

Problem: OPTIONS:
- pure element
- solute
- magnetic compound
- molecular compound
Q: Answer the following question given this paragraph: In the first beaker, distilled water does not conduct a current because water is a molecular compound. In the second beaker, solid sodium chloride also does not conduct a current. Despite being ionic and thus composed of charges particles, the solid crystal lattice does not allow the ions to move between the electrodes. Mobile charged particles are required for the circuit to be complete and the light bulb to light up. In the third beaker, the NaCl has been dissolved into the distilled water. Now the crystal lattice has been broken apart and the individual positive and negative ions can move. Cations move to one electrode, while anions move to the other, allowing electricity to flow (see Figure below ). Melting an ionic compound also frees the ions to conduct a current. Ionic compounds conduct an electric current when melted or dissolved in water. Q: In the first beaker, distilled water does not conduct a current because water is a what? A:
Answer: molecular compound

Problem:OPTIONS:
- intestines
- lungs
- esophagus
- kidneys

Answer the following question given this paragraph: The two adrenal glands are glands located just above the kidneys. Each adrenal gland has an outer layer (cortex) and inner layer (medulla) that secrete different hormones. The hormone adrenaline is secreted by the inner layer. It prepares the body to respond to emergencies. For example, it increases the amount of oxygen and glucose going to the muscles. Q: The two adrenal glands are glands located just above the what? A:
****
A: kidneys

Answer the following question given this paragraph: Apocrine secretion accumulates near the apical portion of the cell. That portion of the cell and its secretory contents pinch off from the cell and are released. The sweat glands of the armpit are classified as apocrine glands. Both merocrine and apocrine glands continue to produce and secrete their contents with little damage caused to the cell because the nucleus and golgi regions remain intact after secretion. In contrast, the process of holocrine secretion involves the rupture and destruction of the entire gland cell. The cell accumulates its secretory products and releases them only when it bursts. New gland cells differentiate from cells in the surrounding tissue to replace those lost by secretion. The sebaceous glands that produce the oils on the skin and hair are holocrine glands/cells (Figure 4.11). Q: The sweat glands of the armpit are classified as these? A:
OPTIONS:
- mucus glands
- pineal glands
- adrenal glands
- apocrine glands
apocrine glands

Answer the following question given this paragraph: Natural resource that is limited in supply and cannot be replaced except over millions of years. Q: What type of resource is limited in supply and cannot be replaced except over millions of years? A:
OPTIONS:
- capital resources
- renewable energy
- human resources
- natural resource

Answer: natural resource

input with options: Answer the following question given this paragraph: Imagine scuba diving and coming upon a jellyfish. Would you be startled if the jellyfish suddenly started to glow with bright yellow light, like the jellyfish in the picture above? If so, then the jellyfish would have done its job. Jellyfish give off light to startle possible predators. The light they emit is visible light. Q: What do jellyfish give off to startle possible predators? A:
OPTIONS:
- energy
- plankton
- electricity
- light
output:
light
