Answer the following question given this paragraph: The female reproductive organs include the vagina, uterus, fallopian tubes, and ovaries ( Figure below ). The breasts are not shown in this figure. They are not considered reproductive organs, even though they are involved in reproduction. They contain mammary glands that give milk to feed a baby. The milk leaves the breast through the nipple when the baby sucks on it. Q: The breasts contain what to give milk to feed a baby? Choices: - sebaceous glands - primordial glands - fetal glands - mammary glands A:
mammary glands
Answer the following question given this paragraph: There are a variety of substances in foods that the body needs. Any substance in food that the body needs is called a nutrient. There are six major types of nutrients: carbohydrates, proteins, lipids, water, minerals, and vitamins. Carbohydrates, proteins, and lipids can be used for energy. Proteins also provide building materials. Proteins, minerals, and vitamins help control body processes. Water is needed by all cells just to stay alive. Q: What do you call any substance in food that the body needs? Choices: - dietary - antioxidant - beneficial - a nutrient A:
a nutrient
Q: Answer the following question given this paragraph: How many species actually exist in the world? No one knows for sure because only a small percentage of them have already been discovered. Estimates range from 5 to 30 million total species currently in existence. Many of them live on coral reefs and in tropical rainforests (see Figure below ). These two ecosystems have some of the greatest biodiversity on the planet. Q: Coral reefs and tropical rainforests are ecosystems known for what, contributing greatly to the species in existence on earth? Choices: - commensalism - mass migrations - spontaneous mutation - biodiversity A:
A: biodiversity
Question: Answer the following question given this paragraph: As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell's needs. This idea is explained in Figure below . However, large cells have a way of dealing with some size challenges. Big cells, such as some white blood cells, often grow more nuclei so that they can supply enough proteins and RNA for the cell's requirements. Large, metabolically active cells often have lots of cell protrusions, resulting in many folds throughout the membrane. These folds increase the surface area available for transport of materials into or out of the cell. Such cell types are found lining your small intestine, where they absorb nutrients from your food through protrusions called microvilli . Q: As a cell grows, its volume increases more quickly than its what? Choices: - density - age - weight - surface area A:
Answer: surface area
