Is evolution a random process? Why or why not.
Bingel [31]

Answer: No

But it is crazy. If Evolution was real things would not be the same as it is today.

Explanation: All life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago, a new study seems to confirm.

Evolution is a theory . Charles Darwin came up with it.

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms. An example of evolution is how cell phones have changed over time.

Explain how a crime lab could use paper chromatography to determine if lipstick found at a crime scene matched the lipstick of a
FromTheMoon [43]

Explanation:

The lipstick from the crime would be crushed and dissolved in an appropriate liquid solvent. The lipstick would then be placed in one of the ink spots on the starting / base line of the paper. Another spot would be created for the lipstick with which it is being compared with.

The paper chromatogram would then be placed vertically on a solvent that acts as the mobile phase. After some time, when the solvent reaches the solvent front  of the paper chromatography, by capillary action, the chromatogram can be removed and left to dry.

Bands will have appeared on the chromatography paper formed from the different components of the lipstick. The bands of the lipstick from the crime scene and that with which it is being compared to are observed. If the bands are all aligned, horizontally, then this means it is a complete match. The lipstick must have been the same used at the crime scene.

Answer:

The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now

2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce

The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation
