Gregor Mendel used only true-breeding plants. If he had used plants that were not true breeding, do you think he would have discovered dominant and recessive traits? why or why not?

How do I use the following terms to create a concept map?
meiosis, eggs, cell division, X chromosomes, sex cells, sperm, mitosis, Y chromosome
It has something to do with like putting a word in a bubble and then like drawing lines from it to another word but I'm not sure.

If each of the offsprings, TT, TT, Tt, and Tt, were allowed to self-fertilize, what are the next possible genotypes in the next generation?

For the question above this, what is the probability of each genotype?

look at our know universe with all the solar systems and galaxies, stars and everything.
Don't you think there can be the same thing inside a molecule where there are atoms and iside atoms are electrons orbiting the core? could anything live on those tiny electrons?

0.010101cm cubed =x meters cubed
What am I doing wrong?
Step 1.) 0.0101010cm cubed x (1000 cm/1 m) x (1000 cm/1) x (1000 cm/1)
Step 2. I'm stuck with10,100,000
Using significant figures and scientific notation, is 101x10^5meters cubed my answer or....because my initial problem started with 4 sig digits is my answer actually 1010x 10^4 meters cubed?

Thanks in advance

Is there an analytical way to solve equations of degree 5 or above without using iterating techniques or the factor theorem?

I know this is impossible, but why is it so? Can anyone give a simple explanation.


The way you usually solve algebraic problems and get the result in the form of:

x = (some function of the coefficients of the polynomial)

What is time?
Daylight savings (moving the clock an hour back) proves that Time as a function of the hands of a clock is just what we have imposed on the natural world. However this can be taken to the greater extent of day/night cycle, seasons and revolutions around the sun in so much as our measurement of it has formed discreat units of time. But that dose not explain what time is.

Is time a force which can be discribed and measured or is a function of something greater than ourselves, or even could it just simply be the way that our brains percive an event (each action following the last in a sequence we call a timeline).

If all time is is just a way for our brains to process an event then could it not be possible to travel through time just by thinking?
Or if time is a function of something larger than ourselves, what?
Or if time is a force created by our universe then could it not be harnessed and used the way we use other forces?

Please explain your answers. Thank you
