Problem:OPTIONS:
- electron bond
- magnetic bond
- integral bond
- ionic bond

Answer the following question given this paragraph: An ionic bond is the force of attraction that holds together positive and negative ions. It forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. The Figure below shows how this happens. Q: What is the force of attraction that holds together positive and negative ions? A:
****
A: ionic bond

Answer the following question given this paragraph: When you are cold, what does your body do to keep warm? You shiver to warm up your body. When you are too warm, you sweat to release heat. When any living organism gets thrown off balance, its body or cells help it return to normal. In other words, living organisms have the ability to keep a stable internal environment. Maintaining a balance inside the body or cells of organisms is known as homeostasis . Like us, many animals have evolved behaviors that control their internal temperature. A lizard may stretch out on a sunny rock to increase its internal temperature, and a bird may fluff its feathers to stay warm ( Figure below ). Q: Maintaining a balance inside the body or cells of organisms is known as? A:
OPTIONS:
- ketosis
- equanimity
- consciousness
- homeostasis
homeostasis

Answer the following question given this paragraph: The uterus is a muscular organ shaped like an upside-down pear. It has a thick lining of tissues called the endometrium . The lower, narrower end of the uterus is known as the cervix . The uterus is where a fetus grows and develops until birth. During pregnancy, the uterus can expand greatly to make room for the baby as it grows. During birth, contractions of the muscular walls of the uterus push the baby through the cervix and out of the body. Q: What is the muscular organ shaped like an upside-down pear that has a thick lining of tissues called the endometrium? A:
OPTIONS:
- kidney
- lungs
- liver
- uterus

Answer: uterus

Question: Answer the following question given this paragraph: Q: What basic plant structure can add support and anchorage? A:
OPTIONS:
- lower leaves
- soils
- stems
- roots
Answer: roots

input with options: Answer the following question given this paragraph: membrane gradients was known, Mitchell proposed that energy captured through the absorption of light (by phototrophs) or the breakdown of molecules into more stable molecules (by various types of chemotrophs) relied on the same basic (homologous) mechanism, namely the generation of H+ gradients across membranes (the plasma membrane in prokaryotes or the internal membranes of mitochondria or chloroplasts (intracellular organelles, derived from bacteria see below) in eukaryotes. What makes us think that these processes might have a similar evolutionary root, that they are homologous? Basically, it is the observation that in both light- and chemical-based processes captured energy is transferred through the movement of electrons through a membrane-embedded "electron transport chain". An electron transport chain involves a series of membrane and associated proteins and a series of reduction-oxidation or redox reactions (see below) during which electrons move from a high energy donor to a lower energy acceptor. Some of the energy difference between the two is used to move H+ ions across a membrane, generating a H+ concentration gradient. Subsequently the thermodynamically favorable movement of H+ down this concentration gradient (across the membrane) is used to drive ATP synthesis, a thermodynamically unfavorable process. ATP synthesis itself involves the rotating ATP synthase. The reaction can be written: H+outside + ADP + Pi ATP + H2O + H+inside, where "inside" and "outside" refer to compartments defined by the membrane containing the electron transport chain and the ATP synthase. Again, this reaction can run backwards. When this occurs, the ATP synthase acts as an ATPase (ATP hydrolase) that can pump H+ (or other molecules) against its concentration gradient. Such pumping ATPases establishes most biologically important molecular gradients across membranes. In such a reaction: ATP + H2O + molecule in low concentration region ADP + Pi + molecule in low concentration region. The most important difference between...

Q: Answer the following question given this paragraph: Fixed joints do not allow any bone movement. Many of the joints in your skull are fixed ( Figure below ). There are eight bones that fuse together to form the cranium. The joints between these bones do not allow movement, which helps protect the brain. Q: How many bones fuse together to form the cranium? A:
Answer:
8
