Bactrian camels, dromedaries, llamas, and alpacas are all members of the same taxonomic
family, Camelidae. Members of this family all have two toes, no hooves, true canine teeth, and
a split upper lip. The family Camelidae originated in North America. The physical features of
animals in this family and the family's geographical origin provide evidence that all these
animals -
A. live in the same type of ecosystem
B. have a common ancestor
C. exchanged DNA at some point in the past
D. have slowly evolved to become herbivores

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.

Which mechanism of transport takes place when solute particles move from a region of high concentration to a region of low concentration? active diffusion isotonic osmosis

Can bacteria reproduce in a way such that when you start out with two bacteria, you get five bacteria? why or why not? * a. yes, because bacteria reproduce sexually, and can produce any number of offspring, just as humans do. b. no, because bacteria grow at an exponential rate. c. no, because when bacteria reproduce, they split into two parts, and two bacteria splitting would result in four bacteria.
