I asked this question about 9 years ago when I discovered what the true effect of smoking a joint was. I haven't smoked in 8 years and this question always stuck with me.

I have an egg but I'm supposed to pretend I don't know its an egg. I have one hour. How do I prove that it is living? (and not non-living or dead). Eggs only have one cell so I can't look at it under a microscope right?

Conjugation mapping can be used to locate genes on a bacterial chromosome. In this example, the F+ strain is able to synthesize methionine, valine, leucine, and histidine. The F- strain is unable to synthesize these amino acids; therefore, they must be supplied in the growth medium. Use the results from replica-plating to answer the questions.

1. Heating ice is an endothermic process which increases the internal energy of the system

2. Evaporation is an endothermic process because the system is absorbing energy.

3. The water in the system is undergoing a reversible process at 273K and 1 atm pressure. Under these conditions, both melting and freezing may occur.

4. Condensation is an exothermic process because the system gives off energy.

5. The melting of ice is an exothermic process because the system absorbs energy.

6.The freezing of water is an endothermic process because the system absorbs energy.

7. As steam condenses, the surroundings are absorbing energy from the system.

I said 1,2,3,4 are trues and 5,6,7 are falses.
But these are wrong answers.
Could anyone please help me with this ASAP??

My doubt is clear in the question. But still i need to add some more details. As we genetically mutate human genes and change characters, why can't we add a few characters of spider to become a spiderman?

I have also heard that hemophlia stems from families that intermarry.
e.g long ago kings and queens would marry closley related cousins, half brother or sister.
So does that also mean that it is a genetic issue as well?
