Regardless of the method used to calculate it, sauropods were indeed large. not all groups of animals become large however. this is generally thought to be because of some negative selective pressures against body size. why might large body size not always be advantageous?
a. larger animals have shorter lifespans and so are more susceptible to extinction
b. larger animals tend to be less successful at mating as they are outcompeted by their smaller counterparts.
c. larger animals have a decreased demand for resources and so can expend ess energy
d. larger animals have trouble maintaining their body temperature due to thermal inertia
e. larger animals have lower fecundity rates and so produce fewer offspring

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.

Pink fur (p) is dominant to purple fur (p) in hamsters. two heterozygous pink hamsters are crossed. what is the probability that these two parents will have an offspring with purple fur? 2/4, 1/2 or 50% 1/4 or 25% 3/4 or 75% 4/4 or 100% there is no chance for this type of offspring
