Answer the following question given this paragraph: The endoplasmic reticulum (ER) is an organelle that helps make and transport proteins and lipids. It's made of folded membranes. Bits of membrane can pinch off to form tiny sacs called vesicles. The vesicles carry proteins or lipids away from the ER. Q: What is the name of the organelle that helps make and transport proteins and lipids? Choices: - plasma membrane - nucleus - mitochondria - endoplasmic reticulum A:
endoplasmic reticulum
Answer the following question given this paragraph: The plasma membranes of cells that specialize in absorption are folded into fingerlike projections called microvilli (singular = microvillus). This folding increases the surface area of the plasma membrane. Such cells are typically found lining the small intestine, the organ that absorbs nutrients from digested food. This is an excellent example of form matching the function of a structure. People with celiac disease have an immune response to gluten, which is a protein found in wheat, barley, and rye. The immune response damages microvilli, and thus, afflicted individuals cannot absorb nutrients. This leads to malnutrition, cramping, and diarrhea. Patients suffering from celiac disease must follow a gluten-free diet. Q: People with celiac disease have an immune response to what, which ultimately leads to malnutrition, cramping, and diarrhea? Choices: - fish - lactose - seeds - gluten A:
gluten
Q: Answer the following question given this paragraph: The density of matter can be calculated by dividing its mass by its volume. Q: How can you calculate the density of matter? Choices: - by subtracting mass from volume - by multiplying its mass by its volume - by dividing its volume by its mass - by dividing its mass by its volume A:
A: by dividing its mass by its volume
Question: Answer the following question given this paragraph: glands in the skin that produce sweat, a salty fluid that helps cool down the body. Q: What do glands in the skin produce to cool down the body? Choices: - lactic acid - saliva - mucus - sweat A:
Answer: sweat

Answer the following question given this paragraph: The outer ear catches sound waves and funnels them to the middle ear. The middle ear amplifies the sound waves and passes them to the inner ear. The inner ear changes the sound waves to electrical signals. The signals travel to the brain, which interprets the sounds. Q: Which part of the ear amplifies the sound waves? Choices: - eardrum - ear canal - cochlea - middle ear A:
**Answer**
middle ear
Q: Answer the following question given this paragraph: Fossils are preserved remains or traces of organisms that lived in the past. Most fossils form in sedimentary rock. Fossils can also be preserved in other ways. Fossilization is rare. It's very unlikely for any given organism to become a fossil. Q: What is the term for preserved remains or traces of organisms that lived in the past? Choices: - deposits - bones - remains - fossils A:
A: fossils
