Do your own homework- that is what school is for. I can understand posting some questions that you are having difficulty with, but this is just pure laziness. Put down the video game controller, and do your own homework. I don't have a problem helping people with concepts they have difficulty understanding, but you haven't even made an effort here.
Reply:That's totally going to get someone to help you.


I doubt it was really 18 out of 100 of your questions...


This just looks to me like you forgot to do your homework.


Good luck on your next test. Report It

Dynamics of Life...help?
No can do! ...My day's of college and studying for botany finals have long been over..Time for you to get "your" homework done. Proceed by opening up your botany or biology book! But what I can do though... is wish you a "Merry Christmas" ..Good luck.

Study for your test beforehand using the textbook and your notes that you took in class.


Plant Reproduction?

I have 3 muliple choice questions i need help with





1- In apple blossoms, the function og the stigma is to?


a) form sperm nuclei


b) Pollinate the ovule


c) Produce the pollen


d) Receive the pollen ( I think this is the right answer)





2- Which reproductive structures are produced within the ovaries of plants?


a) Pollen grain


b) Sperm Nuclei


c) Egg nuclei


d) Pollen tubes (I think this is the right answer)





3) Two flowering plants grew in the same yard. Each fruit developed on one plant, but never on the other. A correct explanation for this observation would be that the plant that never produced fruit...


a) Had flowers with stamens only ( I think this could be the answer)


b) Had flowers with pistils only


c) Produced cones


d) Produced Spores

Plant Reproduction?
You get 2 out of three! The correct answer to number 2 is c ... egg nuclei. Egg nucleus is in the ovule inside the ovary; the pollen tube grows down the style and enters the ovule through the micropyle.

i would say complete because it has pistin( female) and stamens (malepart). it is also completely formed. lol im answering all yur questions.


How do you define perfect and what impact has it had on your view of the world, life, and god?

per·fect





adj [púrfəkt]


1. without faults: without errors, flaws, or faults


in perfect condition





2. complete and whole: complete and lacking nothing essential


We had a perfect day together.





3. excellent or ideal: excellent or ideal in every way


That’s the perfect word to describe him.





4. especially suitable: having all the necessary or typical characteristics required for a given situation


the perfect candidate for the job





5. skilled: very proficient, skilled, or talented in a particular area


a perfect host





6. flawless: without any flaw or blemish


perfect teeth





7. utter, absolute, complete: used to emphasize the extent or degree of something


a perfect nuisance





8. exactly reproducing something: exactly reproducing an original


a perfect likeness





9. botany with stamens and pistils together: used to describe a flower that has functional stamens and pistils in the same flower

How do you define perfect and what impact has it had on your view of the world, life, and god?
I once worked in a sewing factory and they gave us a course in Industrial Psychology. We learned how to place tools where they could be reached quickly and lots of other tricks to improve performance. I now apply this to my personal life. For instance, I have scissors on both sides of the room, so they're right there when I need a pair. Getting things done quickly is something I obsess over and it has caused me problems.


I used to make Funnel Cakes and homemade lemonade for large crowds. I had a system down that could get 6 funnel cakes out the window in less than 3 minutes, plus the lemonade. It was very effective except for one thing. The customers generally screwed up the whole process most of the time. It took a long time, but I finally realized you cannot work with people like you do machines. When I started making allowances for the imperfection of the people who didn't know my system, I was able to relax, make allowances for screw ups and actually enjoy my work.


I think God makes allowances for our imperfections and screw ups and we should make those allowances both for ourselves and for others.
Reply:My point was that while machines are expected to work perfect, people and life cannot. If we make allowance for, even plan for the imperfections, our lives run smoother.


"Perfection is not an option" Report It

Reply:God's definition is the one that matters. either "sinless" or "covered by the blood". Since I'm not sinless, I have to trust in the sacrifice Jesus made for all of us.
Reply:My definition:


"nobody's perfect, not even the perfect fool."





Followed by:


"Impossible"
Reply:Perfection, like any other infinities ascribed to God, results in numerous paradoxes.





I use this on occasion, when I use my argument that proves that God cannot exist because my toaster does not speak Italian.
Reply:My husband is perfect for me. But he is not flawless.
