The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.

Scientists bred the moths and figured out that the light-colored form of the peppered moth has different genes from the dark form. The black color of the dark form was due to a mutation in the DNA of the light-colored form.

I believe that I know what you are talking about however a better layout or source would be nice.
3:I’m sorry I’m not really sure how to answer this one but I’m going to assume that you mean from dark to light. So they liked this time period because the trees were darker due to pollution, this made the darker moths survive from predators while the lighter color moths would be eaten, over time, natural selection would do its course and the whole population of moths would be dark.
4:Well I kind of already answered this but the majority of them were dark because the lighter ones would not be camouflaged therefore making them be easier target for predators and makes the darker moths breed out the lighter ones.
5:Well giraffes cannot live without food so the giraffes with shorter necks would slowly die off making it so only the long necked one would be able to reproduce with babies which would also have long necks, over a long course of time, the shorter necks would be completely gone.
6:Well I wouldn’t say they “grow” longer necks. It’s more like genetic mutation made it so random giraffes would get longer necks then others, since giraffes live in an environment where they have to have long necks only the giraffes with that genetic mutation would survive, and as a said, the longer neck giraffes could only breed with the other Long necked giraffes cause those are the only ones that could survive.

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.

Why is bacteria placed in the kingdom prokaryotes
sukhopar [10]
Prokaryotes are chiefly defined as cells without a nucleus to contain the genetic information. Bacteria do not have a nucleus but, like prokaryotes, a nucleoid region in the center where the DNA can be found. Bacteria also do not have membrane-bound organelles, but they do have ribosomes to synthesize proteins. Bacteria vary a lot in the different structures they can have, but these basic factors make bacteria prokaryotes.

Hope this helps! :)
