Q: Answer the following question given this paragraph: Q: Cells in a biofilm secrete what to recruit nearby cells? A:

OPTIONS:
- signaling proteins
- harnessing molecules
- signaling neurons
- signaling molecules

A: signaling molecules

input: OPTIONS:
- rovers
- shuttles
- sensors
- satellites Now, answer this question: Answer the following question given this paragraph: One of the first uses of rockets in space was to launch satellites. A satellite is an object that orbits a larger object. An orbit is a circular or elliptical path around an object. Natural objects in orbit are called natural satellites. The Moon is a natural satellite. Human-made objects in orbit are called artificial satellites. Q: What did rockets help launch into space during their beginning? A:
A:
output: satellites

Answer the following question given this paragraph: make up the middle layer and the bulk of the heart wall. The outer layer of cells is called the epicardium, of which the second layer is a membranous layered structure called the pericardium that surrounds and protects the heart; it allows enough room for vigorous pumping but also keeps the heart in place to reduce friction between the heart and other structures. The heart has its own blood vessels that supply the heart muscle with blood. The coronary arteries branch from the aorta and surround the outer surface of the heart like a crown. They diverge into capillaries where the heart muscle is supplied with oxygen before converging again into the coronary veins to take the deoxygenated blood back to the right atrium where the blood will be re-oxygenated through the pulmonary circuit. The heart muscle will die without a steady supply of blood. Atherosclerosis is the blockage of an artery by the buildup of fatty plaques. Because of the size (narrow) of the coronary arteries and their function in serving the heart itself, atherosclerosis can be deadly in these arteries. The slowdown of blood flow and subsequent oxygen deprivation that results from atherosclerosis causes severe pain, known as angina, and complete blockage of the arteries will cause myocardial infarction: the death of cardiac muscle tissue, commonly known as a heart attack. Q: What is the term for the blockage of an artery by the buildup of fatty plaques? A:

OPTIONS:
- fibrosis
- cancers
- clumps
- atherosclerosis

Answer: atherosclerosis

Problem: OPTIONS:
- naturally dioxide
- carbon monoxide
- liquid dioxide
- carbon dioxide
Q: Answer the following question given this paragraph: Gas exchange is the movement of oxygen into the blood and carbon dioxide out of the blood. Q: In gas exchange, oxygen flows into the blood, and what flows out? A:
Answer: carbon dioxide

Problem:OPTIONS:
- bent
- trigonal planar
- linear
- tetrahedral

Answer the following question given this paragraph: As for methane and ammonia, the domain geometry for a molecule with four electron pairs is tetrahedral. In the water molecule, two of the electron pairs are lone pairs rather than bonding pairs. The molecular geometry of the water molecule is bent. The H-O-H bond angle is 104.5, which is smaller than the bond angle in NH 3 (see Figure below ). Q: The domain geometry for a molecule with four electron pairs is called what? A:
****
A: tetrahedral

Problem:OPTIONS:
- chromosomes
- electrons
- cells
- ribosomes

Answer the following question given this paragraph: The nucleus of many cells also contains a central region called the nucleolus . The job of the nucleolus is to build ribosomes. These ribosomes flow out the nuclear pores into the cytoplasm. Ribosomes are organelles that make proteins in the cytoplasm. See the composition of the nucleus pictured below ( Figure below ). Q: The job of the nucleolus is to build what? A:
****
A:
ribosomes
