> "When we began, we thought the project would take six to nine months," says Katelyn Larkin, who earned her bachelor's and master's degrees in biology at the UI and has worked in Neiman's lab since she was a sophomore. "Instead, it took more than three years. We learned that these snails grow at a snail's pace."
> The answer may lie in part to a parasitic worm that preys upon the snails. The asexual females are more vulnerable because their offspring's genomes are exact replicas of their own, making them easier to target and wipe out. The sexual females, because they mate, inherit a separate, distinct genomic set that diversifies the gene pool and thus makes them better able to withstand parasitic attacks.
Exactly like in a book on biology I was listening to.
The Red Queen hypothesis, also referred to as Red Queen's, Red Queen's race or The Red Queen Effect, is an evolutionary hypothesis which proposes that organisms must constantly adapt, evolve, and proliferate not merely to gain reproductive advantage, but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment, and intends to explain two different phenomena: the constant extinction rates as observed in the paleontological record caused by co-evolution between competing species and the advantage of sexual reproduction (as opposed to asexual...
Now this is a strange sentence: "The answer may lie in part to a parasitic worm that preys upon the snails."
Maybe the proper form is "the answer may lie in part in a parasitic worm.."

Q: "Everyone working on this together has come to a different conclusion" or "conclusions"?

user142781 Everyone working on this together has come to a different conclusion. Since everyone work on this come to a different conclusions, why "a different conclusion" instead of "different conclusions"?

Everyone doesn't seem to combine well with "together".

A great cartoon:
The Wind Rises (Japanese: 風立ちぬ, Hepburn: Kaze Tachinu) is a 2013 Japanese animated historical drama film written and directed by Hayao Miyazaki and animated by Studio Ghibli. It was released by Toho on July 20, 2013 in Japan, and by Touchstone Pictures in North America on February 21, 2014. The Wind Rises is a fictionalized biopic of Jiro Horikoshi (1903–1982), designer of the Mitsubishi A5M fighter aircraft and its successor, the Mitsubishi A6M Zero, used by the Empire of Japan during World War II.

Q: What is 'explain like I'm five'?

Ruchir MIn my recent question, I got this link in an answer. Here, 'Explain like I'm five' is written. I tried to find its meaning on the Internet, but I got only an acronym ELI5. Is 'explain like I'm five' a phrase or an idiom? What does it mean?

Judging from this and many of my recent answers, answers to easier questions have better chances to get more votes on ELL.
The answers tend to be shorter, and they're easier to read, and it's easier for most users to know whether the answers are correct or not, perhaps.
BTW, I just went outside, and the weather reminds me of Frankfurt!
(And it snowed in Taiwan!)
Oh! It will get even colder next week!

After all, the basic (uninverted) position for a subject in English is to the left of the verb.

So in 2 it's hard to conclude that it's not a subject.

Anonymous
In 1, we have what looks like inversion, with the verb semantically predicating on the right-hand side cold temperatures, and with what appears to be a PP dependent on the left-hand side, where we'd typically find a subject.
 
I wonder if it's really an inversion.

@snailboat I know turns red is more common than turns color, but is there a better substitute for what the OP seeks in the question?
A status bar will turn from "colorless, transparent, or white" to a color. So the status bar (blank).
Of course, turns red is too specific, as it might turn any of a variety of colors (I suppose!)

I liked some of the versions with fade.
 
Anonymous
Is there some reason they can't be more specific, by the way?
 
I read some of the links and saw that "fade in" is used to mean, well, appear or transition from not-something to something.
But it doesn't seem to fit here, and also, it's a specialized term.
 
Anonymous
In software, you commonly fade from one thing to another.
 
So we'd want to know if an audience could be expected to understand it.
Then we need to specify that a color will fade in.
A status bar will transition from some non-colored state to a colored state.

@snailboat Can/should I add this to my answer, snailboat?
I'd like the OP to see it.
@CopperKettle In my mind's eye, @CopperKettle is a whole lot of girl!
That's girl as non-count, isn't it?
 
@JimReynolds Hehe, but it sound unnatural.. Shouldn't it be "a whole lot of a girl" (in a derogatory sense)?

No, it can be very positive.
I mean, not to call a man a girl .. but ..
Oh. No. We would say "a whole lot of girl" where "girl" is "girlness" not a girl.
 
11:55 AM
@JimReynolds Oh! Another example of a mass "girl".
 
It can mean a large girl, jokingly. But not necessarily.
It can mean very girlish. A whole lot of woman makes more sense as a positive term to most people today, I think.
Very womanly in a sense of the goodness or sexiness or whatever it is about womanhood we may like or love.

I am now not very sure if that is a fused relative construction, though it looks like one
WHY?
Refer to page no. 1073 of CGEL
According to the diagram, there should have a gap for the relative modifier clause. But in our sentence that is missing.

His parents lived across the corridor, in another room. All the amenities were down the corridor, and in the middle of the corridor there was a door to a communal kitchen.
I'm not sure how such houses are called in the West, because there are probably no such houses. They resemble hostels, only that people live there for decades.
 
3:38 PM
@Man_From_India Well, CGEL distinguishes "fused relatives" from "embedded questions" (6.2, 1070 ff), a distinction I'm not comfortable with: I think these are not two different constructions but two different uses of the same construction. But there's certainly a gap: for instance, in I don't know whether I will choose A or B the gap is the object of choose; this might be represented as I don't know which of A or B I will choose _.
 
Hmmm...That distinction didn't make much sense to me either.
Yes, your which sentence does have a gap. But the sentence with whether!!! I am not very convinced.
But I still think there is a meaning gap in the original sentence. Is that sentence correct?
 
But that's what whether means: which of either.
 
(though I understand what that sentence mean)
