COMPARE: How were the outcomes of Pasteur's
and Redi's experiments similar?
Both experiments proved that life can come
from rotting meat.
Both experiments proved that spontaneous
generation occurs.
Both experiments showed that heat kills
microorganisms
Both experiments showed that living things
only come from living things.

Both experiments showed that living things  only come from living things is the right answer.

Explanation:

Redi in his experiment took the jars having rotten meat which attract flies. He covered one jar and left the other open the open jars was swamped with maggots while the covered one remains as such.

However, he went to refine his experiment he closed a jar with pores on the cloth the flies throng the cover by the smell of rotten meat and meat remained untouched. He concluded that flies are necessary to produce more flies and hence rejected spontaneous generation.

A nutrient broth for microbial growth is kept in one long neck and other bent neck flask. He sterilised them and exposed the bottles with air. After several weeks he found a turbid appearance in straight neck bottle. He concluded that air borne microbes have fallen in straight tube and contamination occurred. He said no spontaneous generation occurs because then the bend neck bottle would have microbes on it. Thus, microbes grew after they got nutrient and preexisting microorganism.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
