If the water cycle were to stop, lakes, rivers and groundwater sources would dry up, glaciers would disappear and precipitation would stop falling. All freshwater resources would be negatively impacted, and life on Earth would completely cease. The lack of freshwater would make it impossible to grow food.
Hope this helps!!!
We will plug in x = 24, and y = 6:
All is wrong except:
6 = 1/4 · 24
Answer: D ) y = 1/4 x
Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
These antimitotics (i.e. taxanes) target microtubule proliferation. The stage of mitosis where it acts is at the M-phase, particularly in the metaphase. The phases of mitosis are prophase, metaphase, anaphase, and telophase. Microtubles first appear at the metaphase.
I believe the biosphere is fragile, because over time all of the pollution us humans have made; If its from air pulloution, acid rain or even water pollution. the toxic acids over time have made the biosphere and the ozon layer weaker and more thin. which causes the biosphere to become weaker.
