Some species of spider use the wind to carry them to new environments. If a spider's environment becomes overpopulated with
other spiders, the spider will spin a long, thin strand of web and attach itself to it When a strong wind comes along, it will catch the
strand and carry the spider to a new location, sometimes many miles away
Four egg-carrying spiders leave a pine forest on the wind and land in four different locations. At which location is a new species
spider most likely to evolve from the traveling spider?
A.
a tropical island 240 miles away
B.
a deciduous forest 2 miles away
C.
another pine forest 12 miles away
D.
a small town 4 miles away

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

not sure if this is what you'r looking for eubacteria and archaebacteria

if you know your abc's you should be able to get your answer or just use google
