Q: Answer the following question given this paragraph: Radiation is the transfer of energy by waves. Energy can travel as waves through air or empty space. The Sun's energy travels through space by radiation. After sunlight heats the planet's surface, some heat radiates back into the atmosphere. Q: Through what form of energy transfer does the sun's energy travel? A:

OPTIONS:
- solar burst
- convection
- Fusion
- radiation

A: radiation

input: OPTIONS:
- metabolism
- digestion
- respiration
- cardiovascular Now, answer this question: Answer the following question given this paragraph: Cardiovascular System: Arteriosclerosis Compliance allows an artery to expand when blood is pumped through it from the heart, and then to recoil after the surge has passed. This helps promote blood flow. In arteriosclerosis, compliance is reduced, and pressure and resistance within the vessel increase. This is a leading cause of hypertension and coronary heart disease, as it causes the heart to work harder to generate a pressure great enough to overcome the resistance. Arteriosclerosis begins with injury to the endothelium of an artery, which may be caused by irritation from high blood glucose, infection, tobacco use, excessive blood lipids, and other factors. Artery walls that are constantly stressed by blood flowing at high pressure are also more likely to be injuredwhich means that hypertension can promote arteriosclerosis, as well as result from it. Recall that tissue injury causes inflammation. As inflammation spreads into the artery wall, it weakens and scars it, leaving it stiff (sclerotic). As a result, compliance is reduced. Moreover, circulating triglycerides and cholesterol can seep between the damaged lining cells and become trapped within the artery wall, where they are frequently joined by leukocytes, calcium, and cellular debris. Eventually, this buildup, called plaque, can narrow arteries enough to impair blood flow. The term for this condition, atherosclerosis (athero- = "porridge") describes the mealy deposits (Figure 20.14). Q: The heart and the arteries and veins are associated with what system of the body? A:
A:
output: cardiovascular

Answer the following question given this paragraph: An alkyl group is a group of atoms that results when one hydrogen atom is removed from an alkane. The group is named by replacing the -ane suffix of the parent hydrocarbon with -yl. For example, the CH3 group derived from methane (CH4) results from subtracting one hydrogen atom and is called a methyl group. The alkyl groups we will use most frequently are listed in Table 12.4 "Common Alkyl Groups". Alkyl groups are not independent molecules; they are parts of molecules that we consider as a unit to name compounds systematically. Table 12.4 Common Alkyl Groups. Q: A group of atoms that results when one hydrogen atom is removed from an alkane is referred to as what? A:

OPTIONS:
- chloride group
- hyrdrogen group
- nitrate group
- alkyl group

Answer: alkyl group

Problem: OPTIONS:

Answer the following question given this paragraph: Humans can see in three dimensions and color. Q: How many dimensions can humans see in? A:
****
A: three

Problem:OPTIONS:
- an article
- a particle
- an enclave
- an organelle

Answer the following question given this paragraph: The nucleus is an example of an organelle . An organelle is any structure inside a cell that is enclosed by a membrane. Eukaryotic cells may contain many different organelles. Each does a special job. For example, the mitochondrion is an organelle that provides energy to the cell. You can see a mitochondrion and several other organelles in the animal cell in Figure above . Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Q: Any structure inside a cell that is enclosed by a membrane is called? A:
****
A:
an organelle
