Some herbicides, such as 2, 4-D are believed to make plant cells divide more rapidly than normal. Why would this kill plants? Why might this be dangerous to humans if it had the same effect on human cells?

I am an amateur, so my answer might not be correct. If I understand this right, you are talking about a non-shaded box, 8x2, inside a larger, shaded box, 10x4. The area of the inner box is 16. The area of the outer box, 40. 40/100 = 16/x x = 1600/40 x = 40 The area of the inne...

In yeast, ethanol is produced from glucose under anaerobic conditions. What is the maximum amount of ethanol (in millimoles) that could theoretically be produced under the following conditions? A cell-free yeast extract is placed in a solution that contains 3.50 × 102 mm...
trig
I see. A trailing ,numer; works. For asin(.8), asin(.8)*180/%pi, numer; produces 53.13... I also found that writing numbers with a trailing .0 forces approximation. And for the built-in constants, float() forces approximation. For example: a: 4.0/5.0$ disp(a)$ b: asin(a)$ prin...

Using b+0 doesn't phase it. The problem is getting wxMaxima to make 4/5 into a decimal. If I use a: 0.8$ b: asin(a)$ print("the angle is ", b)$ Then it works. It gives me the angle is 0.92729521800161 But if I try to convert that to degrees: c: b*180/%pi$ print(&...

I am trying to get wxMaxima to give me arcsin(4/5), either in radians or degrees. I am using a: 4/5$ b:asin(a)$ print("the angle is ", b)$ But it returns the angle is asin(4/5) How do I get wxMaxima to give me the angle? I want .927 radians or 53.1 degrees.
Physics
I am not an expert. I am a very rusty amateur, so this has to be checked. But I think the difference in light travel distance you are talking about measuring is 2mm. That is, 1mm out into some 1mm deep feature in the object, and 1 mm back. Plus the 2 km there and back. But for...

Ok.. "The strongest recorded earthquake in the world took place in Child on May 22, 1960. It had a magnitude of 9.5 on the Richter scale. The strongest quake actually recorded in Canada was magnitude 8.1 on August 22, 1949 and occurred off the Queen Charlotte Islands. a)H...
