why are grains in a maize always borne in even numbers in a single row?

I think your teacher expects you to look it up in your text.

no even the same kind of apple can have a different number of seeds it is basically luck of the draw

First, note the word "true-breeding".  That indicates each plant is homozygous for all those traits, which means that you don't have to worry about that plant being het for any of those genes.  And it means that they only make a single kind of gamete with regard to thsoe 4 genes.\n\nTechnically, these loci might all be linked to each other, you would need F2 data to know for sure.  But you are supposed to assume that four traits are controlled by 4 genes.\n\nNow, since the parents were homozygous for all their genotypes, the offspring will all be identical, they will all be het for those genotypes.  And which ever phenotype they are, that's the dominant one for that trait.  So purple, green, terminal, and yellow are the dominant phenotypes.\n\nAnd there are 16 different gametes to be made, because there are 4 genes (presumably) and each is het in the F1.\n\nThe only way for an F2 to show all 4 recessive phenotypes would be for it to get a gamete from each parent taht also had all four recessive alleles.  So 1 in16 gametes will fit the bill, so the odds of getting that gamete from on parent is 1 in 16, the odds of getting it from the other parent is 1/16, so the odds of getting it from both is 1/256.

Same plane and not parallel as other answers have said, but the reference to moving balls complicates things. The balls are not guaranteed to meet, and since they are in unidirectional motion, their paths will not cross if they diverge initially. Such paths are not extended in both directions as the definition of a line requires.

odd numbers added to another odd number will always equal an even number.

Corn is a generic English term that predates the discovery of America and means basically "cereal grain".  In American English these days it means the specific cereal grain Zea maize, or maize,that was grown by Native Americans, and is now grown world-wide.  So if you are American, the answer is "they are the same thing".

there are two ways they make them out here, the first and least labor intensive is when they plant the corn with a tractor they use a computer program to spray the seeds in a predetermined pattern and it grows up and the maze is there ...... the other is when the field is planted and the corn stalks are 2 to 3 feet high, you go out with a sickle and hoe and make the maze buy hand and eye .......the most complex corn maze's are generated but computer and planted by a tractor spreading seed in a pattern .....

Two of those, C and D are very weak analogies.\n\nFish can live in rivers but might not.  Tractors can be used on farms but might not.\n\nSo, you're left with A and B.  A foot is on the end of a leg.  An auto is stored in a garage.\n\nYou might not know what "granary" means, so guess.  Does it sound like grain is on the end of a granary or like grain is stored in a granary.\n\nEither way, you've now got a 50/50 shot instead of 1 in 4.  And that's a great improvement.

1, 11, 21, 1211, 111221, 312211, 13112221, ....\n\nthe odd terms (reading from left to right) enumerate the number of times the same figure (which will be specified to its right) appears in the last term of the sequence.\nSo there can be at most three consecutive equal figures in a term: this happens when a figure appears a number of times equal to itself in the previous term, and also the consecutive figure (different from it) appears the same number of times. As the next figure must be different, it cannot give the same figure as a fourth after the first three.\nFor the same reason, the figure before a sequence of three equal must denote a figure different from the one which has been repeated three times, otherwise the count of that figure would have been different.

This is an archaic measure which is equal to:\n\n480 grains to 1 troy ounce (apothecaries' ounce)\n\nor \n\n437.5 grains to 1 avoirdupois ounce\n\n\n1 grain is approximately 0.0648 grams

Even numbers are divisible by 2 (2,4,6,8,10, etc) whereas odd are not (1,3,5,7,9, etc)

I can't see the rest of your question, but even numbers can be multiples of three. Like 6 (2x3). They are not mutually exclusive.

Combines are equipped with removable heads (called headers) that are designed for particular crops. While a grain platform can be used for corn, a specialized corn head is ordinarily used instead. The corn head is equipped with snap rolls that strip the stalk and leaf away from the ear, so that only the ear (and husk) enter the throat. \n\nS.S.

Have a play in game between the 8 and 9 seeds.\n\nThen:\nRound one\n1 v. 8/9\n2 v. 7\n3 v. 6\n4 v. 5\n\nRound two:\n<1/8/9> v. <4/5>\n<2/7> v. <3/6>

A way of visualising this is to think of soldiers on parade. If there are 7 soldiers in a row and 7 rows of soldiers (making a square formation on the parade ground) how many soldiers are there in the square formation?\n\nClearly it is the number of soldiers per row x the number of rows (as it would be for a rectangle) but in the special case of a square formation, these two numbers are the same, so multiply 7 by itself

about a gazillion kernels per row of at least 20 meters wide.

Like rand uses between 0 and 1, and all real numbers in between have the same probability to appear the distribution is uniform. If it were not the case then the numbers generated could not be named "random".
