Say that I have a child. I'm homozygous for my big eyes which is the dominant trait and my husband is heterozygous for his small eyes. Is it possible for my child to inherit small eyes b/c i did the punnette sqare and it turned out like this. EE,EE,Ee,Ee. E=dominant and e= recessive. Obviously the E took over all so is it still possible though?

in spite of beign an intelligent creatures and be able to think,create and talk we are week physically and vulnerable,we are not as fast as cheetahs,not as strong&frosious as tigers,not able to fly as falcons,swim like dolphins.If we get attacked on a street or by animals we (humans) we be dead in matter of seconds,if we are bitten by sharks or tigers or snakes,or even other human we can't survive.
so im thinking that all humans should stop wearing those stupid clothes and wear what provide protections at least aganist normal threats (.pollution) because a belive that there will be a time where you can't go out unless you wear protection suit

a) It activates the complement cascade.
b) It binds to TCRs and MHC molecules outside the normal sites of interaction.
c) It inhibits presentation of antigen by macrophages and B-cells.
d) More than one answer is correct.

I do not think its C. I believe B is a right answer. I'm not sure about A. If A is also correct, then the answer would be D =)

We all hear about coffee and tea having caffeine, and that we shouldnt drink them before bed as they are stimulants... but do they really have a big effect on you?

Ok perhaps they may give you a boost for like 10 minutes, but after that is it much again back to zero? I doubt the 'doses' of caffeine in these drinks are really strong.

I always have a cup of tea or some coffee around 1/1.5/2 hours before I go to bed, and often have it when I get home from Uni. Usually what it does is make me feel snug and warm, almost relaxing me instead of stimulating me. But it only lasts for around 10 mins, and I dont see why people make such a fuss.

Please explain the facts! Thanks!

If God made the world in 6 days and it would have come to that state itself through many years of evolution how would we know the difference? Even if evolution were true it does not mean that an all powerful being did not make the world in the way described by the bible.

I know Euglena have eyespots, as do Volvox. Two queries:
What other species of protists move towards light?
Do any of these three--amoeba, paramecium, or stentor--move towards light?

What will be the charactheristic of that boy ?

And are there any possibility that this phenomena may happen (by clone, or genetic recombination)?
If it could happen, will the morule grow well (into foetus, baby, and finally a human being)?

Thanks 4 ur answer, sorry if my English is bad.
