asexual reproduction differs from sexual reproduction in that, in asexual reproduction
(1) new organisms are usually genetically identical to the parent
(2) the reproductive cycle involves the production of games
(3) nuclei of sex cells fuse to form a zygote
(4) offspring show much genetic variation
o offspring show much genetic variation
o
nuclei of sex cells fuse to form a zygote
the reproductive cycle involves the production of gametes
new organisms are usually genetically identical to the parent

Option 1

Explanation:

In asexual organism, there is only one parent involved hence there is no crossing over or homologous recombination of genetic material from another parent hence the offsprings are genetically identical to the parent without any genetic variation. No gametes are involved and common modes of asexual reproduction includes budding etc.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.
