Breeding rabbits-- determine the relative positions of these three genes and the rfs between the first and second gene, and between the second and third gene.

h+ rightarrow one (dom), h rightarrow two heads (rec) e+ rightarrow long ears (dom), e rightarrow short ears (rec)
c+ rightarrow black (dom), c rightarrow white (rec)

cross e+ h c+ x e h c rightarrow 1000 offspring
e h+ c e h c
(gene order is drawn arbitrarily, and is unknown)
260 black, two-headed, long eared
280 white, one-headed, short eared
16 white, two-headed, long eared
14 black, one-headed, short eared
70 white, one-headed, long eared
80 black, two-headed, short eared
130 black, one-headed, long eared
150 white, two-headed, short eared

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
