I don't mean the North Star. This one was EXTREMELY close to the moon. Do you know what it was? I called & left a message for the weatherman to call back & tell me. Guess he thought I was "luney"! (Pun intended!)

In April 2004, scientists at Tokyo University of Agriculture used parthenogenesis successfully to create a fatherless mouse.
In theory, artificial human parthenogenesis could be used to reproduce humans, but this is highly unlikely due to ethical concerns. Use of an electrical or chemical stimulus can produce the beginning of the process of parthenogenesis in the asexual development of viable offspring.On August 2, 2007, after much independent investigation, it was revealed that discredited South Korean scientist, Hwang Woo-Suk, produced the first human embryos through parthenogenesis.The offspring of parthenogenesis will be all female if two like chromosomes determine the female gender (such as the XY sex-determination system), but male if two like chromosomes determine the male gender (such as the ZW sex-determination system), because the process involves the inheritance and subsequent duplication of only a single sex chromosome.”

i was wondering if there''ll be any reactions going in between BF3+NaF? since they both contain the same anion, if they do 'exchange anions and cations', wouldnt the product be the same? so is it right to say that as long as the cation/anion of two molecules is the same, no reaction will occur? eg between HCL and H20?

No, I am not a Werewolf. It's uncanny how it affects me. Feel all sleepless. Is this a similar phenomina to the tidal pull due to mass and volume that one spacial body has on another. Is the moon pulling on the juices/water in me? Ha! Really, why is this? Must be a basis in fact on this.

Has anyone heard or know of the fact that apparently, there is a compound not found on earth, that can be processed to become a sort of non lethal fuel. It can be burned or used without polluting.
China has become aware of this and they are working very hard to get to the moon ...and start mining.
I hear a spaceship full of this stuff, will provide electricity for a city the size of New York for six months.
Anybody know about this stuff and what it is called and if this is true? Sounds very Buck Rogers to me. Lemme know

Ones that reproduce through their roots with their roots, and ones that produce seeds under ground?

Also, do both of these need to be pollinated with neighboring plants to do this, or are they strictly asexual?

There has been a lot of research and an equally large amount of money spent on teaching animals ( especially apes) a form of language. Research some of the work done attempting to teach animals to communicate. Write about summarizing the research. What gains and loses have occurred and have we taught animals to communicate with us and to what extent?
