does anybody have an idea for a hypothesis?....?

Question

ok I'm doing a science project and we're trying to figure out why blonde, black, brown , red, grey, and white are the only natural hair colors... does anybody have an idea why that I can make my hypothesis?

Answer 1

A hypothesis is just a statement that can be tested (experiment). Sometimes hypotheses are true, and sometimes they are false. The more important issue is how are you going to test it.

Hypothesis: Blonde, black, brown, red, grey and white are the only natural hair colors.

Then design experiment to test this statement.

However, this is an experiement that is impossible to test with any reliability.

I would suggest a twist on the question, and narrowing down the scope...like...the frequency of natural black hair is higher than the frequency of red hair in . Then you could take a sample of the population and correlate this to the entire population. This would use some principles from ecology.

Answer 2

Actually that's not a bad science project to get into, why is that we don't see green or blue hair colors? All the colors that we see are limited to warm hues, that is to say, reds, oranges, yellows, and all the shades and saturated versions of them, which produces the other colors like brown, tans, greys, even black. Saturation could be caused by textural qualities of the hair itself, in that if unabsorbed white is scattered, that would tend to saturate the natural color of the hair, making it more ashy, for example. Decreased or lack of natural color of the hair can produce the same results, and greys as well. Black is actually an highly absorbtive natural color, which is why as one ages, it tends to fade into greys and finally white. So, main question is, "why is the natural hue of the color only warm colors?" For that, I would check into the melanins in the hair, which is also responsible for human skin colors. I'm not sure if melanins absorb blue-green region of the light spectrum, leaving the warm region, or if melanins absorb the full light spectrum and only emit the warm region. For that, analysis of the electron orbital energy levels in the excited melanin molecule would be needed. If I were to make up an hypothesis at this stage, I would say, "Because black is a naturally occuring hair color, melaninn is likely to be naturally absorbtive of the entire visible light spectrum, and what gives it color is its photoemissive spectrum", rather than non-uniform absorptive spectrum.

You're not going about it the right way. First, do all your research and plan out what you want to write, THEN do your hypothesis, not other way around. It's lot more difficult to get data to suit your hypothesis than to suit your hypothesis to the data.

Answer 4

In statistical s prognosis you could group your documents utilising your convey variables. on your question your documents are top and Foot length. the specific variables are 3 hundred and sixty 5 days and place. you could verify if there are modifications in top or foot sizes in different 3 hundred and sixty 5 days tiers and/or place. you ought to use t-attempt for 2 propose assessment or ANOVA (for testing different skill). you additionally can use the non-parametric equivalent.

Answer 5

I'd guess anything that could cause those pigments would be fatal to humans. Find what allows for the coloration in parrots, lizards, and squid and ingest to prove!
