Answer 12

Adenosine Triphosphate

Question 13

“This structure’s split deactivation is responsible for the tortoiseshell and calico patterns on some cats. This structure’s lyonization creates a remnant Barr body. A child will always inherit a copy of colorblindness on this chromosome if the mother is red-green colorblind. For the point, name this sex ____________ which female mammals have two copies of.

Answer 13

Chromosome

Question 14

__________ is a protein in red blood cells that transports oxygen from respiratory organs throughout the body.

Answer 14

Hemoglobin

Question 15

“The name of this group is taken from the tendency of its members to form salts when reacting with metals. The elements in this group are so highly reactive that they are not found free in nature but instead in compounds or in a diatomic state. The reactivity of this group is due to its seven valence electrons. For the point, what is this seventeenth group of the periodic table which includes chlorine, fluorine, bromine, and iodine?”

Answer 15

Halogens

Question 16

“The centimorgan unit maps loci on these structures, consisting of p and q arms. Crossing over occurs between homologous pairs of these structures. A karyotype can show the diploid number of these, 46 in humans, as well as the presence of three of number 21 in a Down syndrome patient. Lining up along the equator during the metaphase of mitosis, for the point, what are these DNA structures?”

Answer 16

Chromosome

Question 17

The earliest estimate of this quantity depended on indirect estimates of the number of particles of latex. Jean Perrin defined this constant, denoted capital N, as the number of atoms in 16 grams of oxygen. For the point, name this constant, approximately 6 times 10 to the 23rd power, that equals the number of particles in a _____.

Answer 17

Mole, avagadro number

Question 18

Organisms in the root nodules of legumes break down the strong triple bond holding this molecule together. This compound is broken down using an iron catalyst in the Haber process, which produces two molecules of ammonia. For the point, name this gas “fixed” by some plants, the most abundant in the atmosphere

Answer 18
