Yep! :)

I would advise drawing a diagram for problems like these, it really helps! Without a diagram though: if the picture is 3.5 feet wide and it is 4 ft to the center of the picture from the ceiling then you want to find the center of the picture first. For that take 3.5/2 and then...

If that is the case, just use length x width x height for each side of the pool and the bottom and add them together to get the total, there is probably an easier way to do this but it is just how I have always done it.

Math
Are you looking for the total surface area of the inside of the pool?

Science
How many do you have? With markers or paint you can easily make a mosaic or even a portrait by lineing them up in different colors or patterns. If you have only one pellet, there is not much you can do with it.

Opinion, I need many people to respond
That is exactly what they do. The only reason SeaWorld would ever bring a wild orca into their care is for rehabilitation purposes and they release them whenever possible. It is very rare for a cetacean to be so badly injured that they can't be released. As far as I know t...

That is the problem. No one knows exactly why or how tonic immobility happens. What I put in my first post is what I found from my own research with live sharks at a research facility. I need to include it in a report next Tuesday and I just need to make sure that it makes sense.

Usually you just dilute it with a base until you get to the desired molarity. In most labs NaOH (Sodium Hydroxide) is used to achieve this. I hope this helps.

I would say that both 1 and 2 are true. 1: For example: remove all plants from an ecosystem. Herbivores and most insects would quickly die off, followed by carnivores and insectivores and so on until there is nothing left. 2: No organism is safe from extinction, there are just...

Sorry I responded so late, I had a class tonight. I'm not 100% sure on this one. C is partially correct because organisms do release heat after digesting plants and other materials but the heat does not come from photosynthesis, instead the origional energy for all energy ...

Actually I read you question wrong, the correct one is mitochondrion, sorry

Science
Unless my Biology teacher lied to me that should be right.

Science
I'll give you a hint. Plasma membrane and nucleus are incorrect but either mitochondrion or chloroplast are correct, one of them carries out photosynthesis which produces oxygen and glucose and uses carbon dioxide, the other carries out cellular respiration which produces ...
