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: 28.5 Adjustments of the Infant at Birth and Postnatal Stages The first breath a newborn takes at birth inflates the lungs and dramatically alters the circulatory system, closing the three shunts that directed oxygenated blood away from the lungs and liver during fetal life. Clamping and cutting the umbilical cord collapses the three umbilical blood vessels. The proximal umbilical arteries remain a part of the circulatory system, whereas the distal umbilical arteries and the umbilical vein become fibrotic. The newborn keeps warm by breaking down brown adipose tissue in the process of nonshivering thermogenesis. The first consumption of breast milk or formula floods the newborn's sterile gastrointestinal tract with beneficial bacteria that eventually establish themselves as the bacterial flora, which aid in digestion. Q: The first consumption of breast milk or formula floods the newborn's sterile gastrointestinal tract with beneficial what? Choices: - disease - oxygen - pathogens - bacteria A:
bacteria
Q: Answer the following question given this paragraph: Sequencing the human genome has increased our knowledge of genetic disorders. These are diseases caused by mutations. They may be caused by single gene mutations or the failure of chromosomes to separate correctly during meiosis. Q: What causes genetic disorders? Choices: - parasites - proteins - pollution - mutations A:
A: mutations

Answer the following question given this paragraph: The muscular system consists of all the muscles in the body. This is the body system that allows us to move. You also depend on many muscles to keep you alive. Your heart, which is mostly muscle, pumps blood around your body. Q: What body system allows humans to move? Choices: - digestive system - abnormal system - lung system - muscular system A:
**Answer**
muscular system
