Hypothesis ALS+ C;
It's phenotype (I think this is correct but i am not 100% sure)
Probably a dark blue bird.But blue and black birds don't mate, they only mate their own kind! or, (second answer) where do you think purple martins come from?
Perform a test cross of two homozygous individuals base on a hypothesis, I usually just guess to begin with. Hypothesis: Example: Purple x White all Purple Then cross the F1 generation (those guys above) Purple x Purple you get the fallowing ratios if the purple allel is dominant 3/4 Purple 1/4 white Usually you are given a number of offspring for problems like this so lets Example: purple x white F1 all purple would mean purple is dominant, you can take it further too. F2 100 offspring= 25 white and 75 purple Note: In real life numbers wont be nice and even like this so you may have to do some chi squared analysis to check your hypotheses.
This is a statement and not a question. Yet, this site can not list every fruit in the world because there are too many. Purple Mangosteen
Purple loosetrife is introduced by Europe.
Contrary to popular belief, the thought that Purple Martins reduce mosquito population was brought up to promote the products that went along with the birds such as housing, and gourds. http://www.purplemartin.org/update/MosCont.html is research that was conducted to back it up. But don't get me wrong, Martins have many advantages. Just hearing that beautiful song they produce makes it worthwhile to attract Martins to your backyard.

Bats eat them. Also, bug zappers are not their friends. Other predators are purple martins, chickens, robins, wrens, blackbirds, guinea hens, and frogs and many fish eat adult insects and larvae.
As bizzare as it sounds. That statement is 100% true. Now, don't get confused and start looking up pictures of the moon scouting for purple spots. It's true only in an if-then statement. IF the moon has purple spots, THEN it is June. If-then statements are made up of two things. A hypothesis, the "if" part, and the conclusion, the "then" part. Now here is where it starts getting confusing. If perhaps the hypothesis should be "illogical" like the moon having purple spots, then the statement would be considered true. On the other hand, if the hypothesis were to be:If it is June, and the conclusion being:then the moon has purple spots. That would be false, because the hypothesis falls under the realm of logic and it's counterpart, the conclusion, is false and illogical.

Purple martins are fairly noisy, chirping and making sounds that have been described as chortles, rattles, and croaks.
yes or no and why is it endangered The purple martin is not an endangered species, and its habitat is still quite good.
Purple martins are completely dependent on humans for nesting boxes. Martins will travel hundreds of miles to return to their nesting boxes as long as they are kept up properly.
Mosquito eggs are needed to feed crayfish, dragonflies and frogs. Flying mosquitoes are food for frogs, bats and birds, especially purple martins. In the bigger scheme of things, mosquitoes help keep ecosystems balanced by transmitting diseases. Diseased animals are easier for carnivores to capture and disease keeps the numbers of certain animals from getting too large for the food supply. That seems kind of cold, but that is the way it is. They probably are not too concerned with their usefulness to humans!
