Which of the following characteristics is unique to angiosperms?
1. pollen
2. vascular bundles
3. thick cuticle
4. lignin present in cell walls
5. a haploid gametophyte retained within tissues of the diploid sporophyte
I thought gymnosperms had pollen, I know they have vascular tissue (and thus vascular bundles?). Thick cuticles are present in some of the earliest plants, I thought. Lignin, as well, is present in early plants. And I thought gymnosperms retained the female gametophyte in a cone, part of the adult sporophyte.
So, by process of elimination, I'm left with... nothing.
Help?

1 AnswerPoetry8 years agoShould I translate a song title into Spanish?
I'm giving an oral presentation for my Spanish class on the band Queen. I'm in High school, and I just wanted to know whether I should translate the band name and/or song title on which I'm doing the presentation into Spanish or just leave them as is. I don't know what the common practice is here, and I just need some advice.
Thanks in advance!
2 AnswersLanguages8 years agoC# Help: How to safely modify Windows Forms Designer code?
I'm writing a Windows Forms project in C# using Visual Studio 2010 Express. I need to make many iterations of a panel, each of which is identical except for name and position. I also need the code to be able to make variable numbers of these (example: one time it runs, it puts 40 on a form, the next time, it might need to put 100 on). I've figured out how to come up with a way of calculating all these properties, but I need a way to actually put them on the form. I've tried building an instance of a class with all the panels I need inside the initialize component routine, but that doesn't work. I've tried creating a second partial class of the Form, but then it gives me this: "The type Form1 is made of several partial classes in the same file."
Any suggestions? Please be detailed in your explanations, I've only been programming for a year or so, and Windows Forms are new territory for me.
Thanks!
2 AnswersProgramming & Design9 years agoIs kexane shopping a legitimite company?
I found an online company called Kexane Shopping. They're selling a calculator for a low (but not unreasonably low) price. They only give an email address for contact, and I can't find any physical address or telephone number for them. The website is http://kexane.com/index.php for their home page. Has anyone heard of them? Are they a real company? Or are they a scam out there to take your money and run?
2 AnswersOther - Internet9 years agoAdvice?? I feel really guilty about this?
Here's the story.
In PE at school, I was playing Capture the Flag. I was chasing this guy to try and get him out, and I was running flat out, and this girl went after the same guy I was chasing. I couldn't stop in time, and I hit her hard enough to knock her over. I got up and made sure she was OK, and apologized over and over, and kept playing. Then, I did it again, this time hard enough to really hurt her. I feel really guilty, and I don't know how to feel better. I apologized over and over, and she forgives me, but it doesn't really help. I feel really guilty and ashamed. Any advice?
PS: she's on my team at school for PE, and in Biology with me, so I can't avoid her, and I don't want to.
