Answer the following question given this paragraph: Chloroplasts Like the mitochondria, chloroplasts have their own DNA and ribosomes, but chloroplasts have an entirely different function. Chloroplasts are plant cell organelles that carry out photosynthesis. Photosynthesis is the series of reactions that use carbon dioxide, water, and light energy to make glucose and oxygen. This is a major difference between plants and animals; plants (autotrophs) are able to make their own food, like sugars, while animals (heterotrophs) must ingest their food. Like mitochondria, chloroplasts have outer and inner membranes, but within the space enclosed by a chloroplast's inner membrane is a set of interconnected and stacked fluid-filled membrane sacs called thylakoids ( Figure 4.17). Each stack of thylakoids is called a granum (plural = grana). The fluid enclosed by the inner membrane that surrounds the grana is called the stroma. Q: Like the mitochondria, chloroplasts have their own dna and ribosomes, but chloroplasts have an entirely different function. chloroplasts are plant cell organelles that carry out what? Choices: - reproduction - digestion - growth - photosynthesis A:
photosynthesis

Answer the following question given this paragraph: Temperature is the quantity measured by a thermometer. Temperature is related to the average kinetic energy of atoms and molecules in a system. Absolute zero is the temperature at which there is no molecular motion. There are three main temperature scales: Celsius, Fahrenheit, and Kelvin. Temperatures on one scale can be converted to temperatures on another scale using the following equations:. Q: What does a thermometer measure? Choices: - oxygen - precipitation - size - temperature A:
temperature

Answer the following question given this paragraph: Like other female vertebrates, all female mammals have ovaries. These are the organs that produce eggs (see Figure below ). Therian mammals also have two additional female reproductive structures that are not found in other vertebrates. They are the uterus and vagina. Q: The organs of female mammals that that produce eggs are called what? Choices: - testes - Uterus - fallopian tubes - ovaries A:
ovaries

Answer the following question given this paragraph: To grow and develop, you must form new cells. Imagine how often your cells must divide during a growth spurt. Growing just an inch requires countless cell divisions. Your body must produce new bone cells, new skin cells, new cells in your blood vessels and so on. Q: A growth spurt requires constant divisions of what? Choices: - hairs - seeds - proteins - cells A:
cells
