Ok! I’m going to go watch Monty Python with my lady. I don’t know if I’ll be back later. If not, then lots of love.
"Would you, um—would you prefer I leave you alone or, like, is company helping? I don’t want to, like, intrude, and I totally get it either way, I just—yeah. I’m rambling."
"I honestly don’t know. But I suppose it’s best if I’m not left alone," Helena admitted. The last time she had been left alone with thoughts like these, she’d decided to try and restart the planet.
What if we could see how the Jovian moon Europa would look like if its ocean weren’t frozen over? This may just be a mere illustrative depiction as done by an artist but it still raises our curiosity and imagination. If creatures lived on such an ocean world without the freezing temperatures who knows what kind of species would rise what kind of intelligence they’d have, adaptation skills, and size! But let me not downplay the fact that species have been shown to survive even on freezing temperatures. This is why I love artistic representations on observations we’ve witnessed in nature. The 'what if' sensations shoot through the roof, and that’s okay.
Europa as It Is Today: Jupiter’s icy moon Europa is slightly smaller than the Earth’s Moon. Like the Earth, Europa is thought to have an iron core, a rocky mantle and a surface ocean of salty water.
Unlike on Earth, however, this ocean is deep enough to cover the whole surface of Europa, and being far from the sun, the ocean surface is globally frozen over.
And why do you not tell us where. You any hold back this perfect information!
My deepest apologies fellow Gail Peck lover, I was distracted by my overwhelming excitement about finding it. Which you can enjoy here http://www.dailymotion.com/RBGPRB
So I found a place where someone uploaded every single Gail Peck scene from Rookie Blue. SO that’s where I’m going to be.
"What did you just call me?" (Cause reasons? XD)
“My main squeeze”
Helen nodded. “I’ll have to agree with you. Perhaps we could listen to music together sometime. I’ve met quite a lot of musicians between our time and now, and I’ve accumulated quite the record collection.”
"That sounds wonderful! I haven’t seen a gramophone in quite some time. I had thought that they’d gone extinct or were cloistered away in museums." Helena grinned. "I’d always tinkered with the idea of trying to improve on Edison’s original when it came out, but I was 11 and I ended up breaking the one my family had." She chuckled at the memory. "I never tried to mess with sound again."
Yeah! So I’ve been doing this for a long time and there are a bunch of you on here. Which is nice. So I’m going to kill two birds with one stone here and practice ma photoshop skillz and reward people for being awesome.
So if you want like a sidebar or a header for your blog then…
Eukaryotes: A Breakdown of Organelles
Organelles are unique to eukaryotes and act like organs in the cell, each performing their own specific functions to keep the whole cell running. Since they’re all in their own little sealed-off membrane-bound areas, they can provide the ideal environment for whatever function they perform—for example, they can adjust the pH or temperature—and thus this allows for much more complexity in the cell.
Most organelles fit into a single functional unit called the Endomembrane system, because they evolved in the same way. The only organelles that don’t fit into this category are the mitochondria and chloroplast—for reasons that will become clear in the next article.
So let’s take a look at the functions of the organelles in the Endomembrane system:
- Nuclear envelope: This compartment contains the cell’s genetic material—the DNA. Its main function is to protect and package the DNA, but it also synthesises RNA, another kind of genetic material.
- Endoplasmic reticulum: Interconnected with the outer membrane of the nuclear envelope, the ER consists of flattened tubes and sacs called cisternae. The endoplasmic reticulum is subdivided into two: the rough ER, where protein synthesis and packaging takes place, and the smooth ER, where lipid and carbohydrate synthesis takes place. Basically, the endoplasmic reticulum uses the information in DNA to create the building blocks of the cell.
- Golgi body: This is composed of a group of flat, membranous sacs that deal with the goods produced in the endoplasmic reticulum. Proteins are transported by vesicles from the cis face (the part facing the nucleus) and a trans face (the part facing away from the nucleus), being packaged, modified and matured along the way. When they emerge the proteins are sent out into the wider environment.
- Lysosome: This is the recycling plant of the cell, containing digestive enzymes that sort, degrade and recycle waste products. It’s actually a perfect example of how organelles can create niche environments: the lysosome maintains an acidic pH of 5, which is ideal for the breakdown of products.
- Vesicle: Membrane-bound sacs used to store and transport material.
- Vacuole: A large, fluid-filled “bubble” in plant cells, where food and waste products are
- Cell membrane: Made mostly of lipids, this encloses the cell and separates it from the outside world. It’s selectively permeable, meaning that only some substances are allowed passage in and out.
And now the functions of those loners not in the Endomembrane system:
- Mitrochondria: This is where cellular respiration takes place—where the cell’s energy (ATP) is extracted from glucose (a sugar). It’s present in all plant and animal cells.
- Chloroplast: Present in plants, the chloroplast takes in light energy and converts it into chemical energy through the process of photosynthesis, ready for use in the mitochondria.
I know I’ve just dumped a whole host of terms onto you, and if they’re totally unfamiliar then they might be difficult to juggle. But trust me, we’ll come back to almost all of these in more detail later, so you’ll have time to digest and memorise.
