If a portion of a strand of DNA bases reads 5' AGCTAGCGT 3, what would the sequence of bases on the complementary strand read?

Independent assortment occurs during metaphase I when homologous chromosome pairs line up randomly at the cell’s equator. This randomness contributes to genetic variation because the distribution of maternal and paternal chromosomes into gametes is different each time meiosis occurs.

The correct answer is C. The digestive system is responsible for breaking down complex food molecules, including proteins, into simpler components such as amino acids that can be absorbed and utilized by the body.

The experiment involves dissolving different substances in water and observing how these solutions cool. The primary variable being tested is how the type of solute (salt, sugar, baking soda) affects the cooling rate, rather than solubility or volume effects.

The correct answer is C. The renal vein is responsible for draining oxygen-depleted blood from the kidneys. After the kidneys filter waste and excess substances from the blood, the deoxygenated blood is carried away from the kidneys by the renal vein

The correct answer is C. Psoriasis is a chronic autoimmune skin condition characterized by the rapid buildup of skin cells, and it is considered a noninfectious disease. Chikungunya, dengue, and brucellosis are infectious diseases caused by specific pathogens.

The correct answer is C. The complementary strand of DNA will have bases that pair with the original strand according to the base-pairing rules. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Therefore, the complementary strand reads 3’ TCGATCGCA5’.

The correct answer is C. Lysosomes are membrane-bound organelles containing enzymes that break down cellular waste, debris, and foreign materials through intracellular digestion.

When a proton is emitted from the nucleus of an atom, the atomic number (Z) decreases by 1 because a proton has a positive charge, and it's effectively removing one positive charge from the nucleus. However, the atomic mass (A) remains the same because protons and neutrons contribute to the atomic mass, and the emission of a proton does not affect the number of neutrons.

The correct answer is B. Atoms become cations by losing electrons. Potassium has one electron in its outermost shell, and it is more likely to lose that electron to achieve a stable, cationic state. Fluorine, helium, and oxygen are more likely to gain electrons and form anions.

The correct answer is C. A spectrophotometer measures the amount of light absorbed or transmitted by a substance in a liquid. Turbidity, caused by suspended particles, can be assessed by measuring the reduction in light transmission through the sample. The other tools listed are not specifically designed for measuring turbidity.
