Determine whether the following species are extinct, endangered, or threatened.
The Tasmanian tiger, the largest known carnivorous marsupial, was wiped out of the wild due to constant
hunting:
The Amur leopard is now gone from most of its original habitat due to human activity. Only twenty to
thirty Amur leopards remain in the wild:
Western Lowland gorilla populations have dropped sixty percent in the past twenty-five years due to
poaching, habitat loss, and, mainly, disease. Their numbers are expected to keep dropping, and the
species could soon disappear:
The Eastern gemfish population has declined due to commercial fishing. New protection efforts seem to
be helping the population slowly recover:
The golden toad was forced from its breeding sites when erratic weather caused pools to dry up. No
frogs have been found in over two decades:

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
