Answer the following question given this paragraph: The 24 human chromosomes. The autosomes are numbered 1 - 22, based on size, with chromosome 1 being the largest. The X and Y sex chromosomes are shown in the box. Q: X and y are the labels of what specialized human chromosomes? Choices: - carb chromosomes - exotic chromosomes - protein chromosomes - sex chromosomes A:
sex chromosomes
Answer the following question given this paragraph: A cyclic hydrocarbon is a hydrocarbon in which the carbon chain joins to itself in a ring. A cycloalkane is a cyclic hydrocarbon in which all of the carbon-carbon bonds are single bonds. Like other alkanes, cycloalkanes are saturated compounds. Cycloalkanes have the general formula of C n H 2n . The simplest cycloalkane is cyclopropane, a three-carbon ring. Q: What is a hydrocarbon in which the carbon chain joins to itself in a ring? Choices: - asymmetrical hydrocarbon - circular hydrocarbon - acid hydrocarbon - cyclic hydrocarbon A:
cyclic hydrocarbon
Q: Answer the following question given this paragraph: The yellow subunits are identical in structure, as are the gray subunits. A smaller organic structure called a porphyrin ring is attached to each protein subunit and contains the iron ion used to bind oxygen. Q: The iron ion used to bind oxygen is on what type of "ring"? Choices: - DNA ring - petrarchan ring - reagent ring - porphyrin ring A:
A: porphyrin ring
Question: Answer the following question given this paragraph: Sometimes cancer cells break away from a tumor. If they enter the bloodstream, they are carried throughout the body. Then, the cells may start growing in other tissues. This is usually how cancer spreads from one part of the body to another. Once this happens, cancer is very hard to stop or control. Q: How do cancer cells typically spread from one part of the body to another? Choices: - plasma - kidneys - liver - bloodstream A:
Answer: bloodstream

Answer the following question given this paragraph: A proton is one of three main particles that make up the atom. The other two particles are the neutron and electron. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67 10 -27 kilograms. Together with neutrons, they make up virtually all of the mass of an atom. For an excellent video on protons and other fundamental particles in atoms, go to this URL:. Q: Which atomic particle has a positive charge? Choices: - the electron - the nucleus - the neutron - the proton A:
**Answer**
the proton
Q: Answer the following question given this paragraph: Superior Rotation and Inferior Rotation Superior and inferior rotation are movements of the scapula and are defined by the direction of movement of the glenoid cavity. These motions involve rotation of the scapula around a point inferior to the scapular spine and are produced by combinations of muscles acting on the scapula. During superior rotation, the glenoid cavity moves upward as the medial end of the scapular spine moves downward. This is a very important motion that contributes to upper limb abduction. Without superior rotation of the scapula, the greater tubercle of the humerus would hit the acromion of the scapula, thus preventing any abduction of the arm above shoulder height. Superior rotation of the scapula is thus required for full abduction of the upper limb. Superior rotation is also used without arm abduction when carrying a heavy load with your hand or on your shoulder. You can feel this rotation when you pick up a load, such as a heavy book bag and carry it on only one shoulder. To increase its weight-bearing support for the bag, the shoulder lifts as the scapula superiorly rotates. Inferior rotation occurs during limb adduction and involves the downward motion of the glenoid cavity with upward movement of the medial end of the scapular spine. Q: Inferior rotation occurs during limb adduction and involves the downward motion of what? Choices: - choroidal cavity - pelvic cavity - dialysate cavity - glenoid cavity A:
A: glenoid cavity
