A science class takes a field trip to a rock formation known for the many fossils it holds. A student finds a fossil that shows a plant with leaves that look like those of a plant that grows nearby. The student tells his classmates that the plant fossil must be from an ancient species that has not changed much over time. Which statement BEST describes the student’s claim? 1) The claim is reasonable because plants do not change over time.

2) The claim is reasonable because fossils often show similarities between extinct and similar modern species.

3)The claim is not reasonable because plants must change over time.

4)The claim is not reasonable because fossils can be made from recently living organisms.

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically

According the inverse square law, doubling the distance from the source of the sound, a speaker, for example, will drop the sound 6 db each time. if you were standing in the back of an auditorium, 32 feet away from a speaker not using any amplification, would you be able to hear a speaker clearly? why or why not?
