Abacteria called e. coli is found in different kinds of foods, including beef. thoroughly cooking beef can prevent infections caused by e. coli.

which conclusion is best supported by this information?

1.e. coli is a harmful bacteria that can be killed by exposure to oxygen.
2.e. coli is a bacteria that can be killed by exposure to oxygen.
3.e. coli is a harmful bacteria that can be killed by high temperatures.
4,e. coli is a bacteria that can be killed by high temperatures.

3.E. coli is a harmful bacteria that can be killed by high temperatures.

Explanation:

extreme heat in beef kills bacteria, like in other foods. This is why we put food in an oven.

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).

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.
