Which scientist disprove the idea that life comes from non life?

The scientist that disproved the idea that life comes from non-life was <em>Luis Pasteur</em><em />

The scientist who tried to prove that life comes from non-life was John Needham. To do this, he took an open flask and put broth in it, heated it up, then sealed it, finding signs of life in it days later. He used that experiment to try and prove that life could come from non-living things.

Luis Pasteur disproved this theory by placing broth in a swan-necked flask, so that it was open to air and bacteria, and heating it up to sterilize it. After a few days the broth did not have any signs of life in it, but if the neck  was cut off, then within a few days the broth began to mold and bacteria started growing. This proved that spontaneous generation does not occur, otherwise the broth in the swan-necked flask would have molded over as well.

Thank you for your question! I hope this helped! Have an amazing day! :D

The mean resting pulse rate for men is 72 beats per minute. a simple random sample of men who regularly work out at mitch's gym
tamaranim1 [39]

Claim: the mean resting pulse rate for men is less than 72 bpm.

Symbolic form would be: μ < 72

Step 1: null hypothesis  : μ > =  7 2 b p m

Step 2: alternative hypothesis:  μ <  7 2 b p m



Step 3: the test statistic is z = mean – μ / standard dev/sqrt (n) = -3/4 / 1.7639 = -1.92


Step 4: c v method: since z α = -1.645, the test static is z = -1.92 is less than the CV, we reject null hypothesis


            P Value method: area is 0.0274, since the p value is <= α, reject null hypothesis.

Step 5: the sample data support the claim that the mean resting pulse rate for men is less than 72 bpm.

Why Do More Species Live Near the Equator? 5 reason why
PtichkaEL [24]

Answer:Species Dynamics. This theory is quite straightforward: species that can colonize new areas faster and reproduce in greater number than they become extinct have the greatest chances to thrive. The tropics offer favorable conditions for these conditions to be met.    

There Is More Diversity Near the Equator. ... Another argues that more solar energy is received around the equator, allowing for greater species richness. A third points out that equatorial tropics are the largest biome, so it makes sense that there would be more species.
