11.) State two possible reasons the deer population has grown so large. [4]
________________________________________…
________________________________________…
12.) Describe one problem the deer may cause in the community. [2]
________________________________________…
________________________________________…
13.) How is the bait and shoot method similar to population control in nature? [2]
________________________________________…
________________________________________…
14.) State one possible problem with the bait and shoot method. [2]
________________________________________…
________________________________________…
15.) Two other proposed methods for population control are:
> trapping and relocating some deer
> treating the deer with birth control drugs
For each of these methods, suggest one possible reasons it was not chosen. [4]
________________________________________…

Pregnant On The Pill?


I’ve been taking the 3 month pill for close to 2 years now. I’m not very good at taking them at the same time everyday and me and my boyfriend have sex regularly. Does anyone know what the chances of me getting pregnant are? Or when a good time to take a test is? Its hard for me to know since I have to wait a month and a half for my next period. If there are any people that may have any information please help. The reason I’m concerned is because I have been feeling nauseous the last few days but I am not sure if its affiliated with that. Anything will help. Thanks!

Olympus Om-d E-m5 — What Are The Olympus Secrets Behind The “world’s Fastest Autofocus System”?


http://olympusamerica.com/corporate/corp…
“World’s Fastest*2 Autofocusing System . . . *2 As of November 2011. Among interchangeable-lens digital cameras on the market, and using Olympus’ in-house test conditions”
1) Do you think that when this camera is tested by organizations such as dpreview.com, that it will prove to have the “world’s fastest auto-focus” ? ?
[bhphotovideo.com says “Expected availability: April 10 2012”]
2) If true, how can a mirrorless camera possibly claim this crown? . . . Any tech-ideas as to what has Olympus may have discovered that Canon/Nikon have not ? ?
3) If the Olympus OM-D E-M5 lives up to all of its pre-release specs [and I’ll venture that Olympus has a pretty good reputation in this regard] — is this camera a good buy at $1000 (body-only)?
