Somebody once told me the world is gonna roll me
I ain't the sharpest tool in the shed
She was looking kind of dumb with her finger and her thumb
In the shape of an "L" on her forehead

Well the years start coming and they don't stop coming
Fed to the rules and I hit the ground running
Didn't make sense not to live for fun
Your brain gets smart but your head gets dumb
So much to do, so much to see
So what's wrong with taking the back streets?
You'll never know if you don't go
You'll never shine if you don't glow

Hey now, you're an all-star, get your game on, go play
Hey now, you're a rock star, get the show on, get paid
And all that glitters is gold
Only shooting stars break the mold

It's a cool place and they say it gets colder
You're bundled up now, wait till you get older
But the meteor men beg to differ
Judging by the hole in the satellite picture
The ice we skate is getting pretty thin
The water's getting warm so you might as well swim
My world's on fire, how about yours?
That's the way I like it and I never get bored

Hey now, you're an all-star, get your game on, go play
Hey now, you're a rock star, get the show on, get paid
All that glitters is gold
Only shooting stars break the mold

Hey now, you're an all-star, get your game on, go play
Hey now, you're a rock star, get the show, on get paid
And all that glitters is gold
Only shooting stars

Somebody once asked could I spare some change for gas?
I need to get myself away from this place
I said yep what a concept
I could use a little fuel myself
And we could all use a little change

Well, the years start coming and they don't stop coming
Fed to the rules and I hit the ground running
Didn't make sense not to live for fun
Your brain gets smart but your head gets dumb
So much to do, so much to see
So what's wrong with taking the back streets?
You'll never know if you don't go (go!)
You'll never shine if you don't glow

Hey now, you're an all-star, get your game on, go play
Hey now, you're a rock star, get the show on, get paid
And all that glitters is gold
Only shooting stars break the mold

And all that glitters is gold
Only shooting stars break the mold

Dwarf mistletoes are flowering plants that grow on certain forest trees. They obtain nutrients and water from the vascular tissu

Galina-37 [17]

Answer:

C) commensalism

Explanation:

Commensalism is an interaction in which one organism benefits without causing any harm to the other. The other organism derives no benefit from the relationship.

The scenario above in which the dwarf mistletoe obtains nutrients from the vascular tissues of trees is a perfect example of such a relationship.

Parasitism is similar to this but the other organism is harmed in the process.

Which kingdom would include organisms that are all heterotrophic and motile?

zlopas [31]

Answer:

Animalia, essentially

Explanation:

First, let's define our terms -

Heterotrophic: consumes other organisms to survive, as opposed to autotrophic

Motile: can move around, as opposed to sessile

There is debate on what constitutes a kingdom, but I generally go with the 6 kingdoms model, which includes animalia, plantae, fungi, protista, eubacteria, and archaebacteria.

Fungi, though heterotrophic, include mushrooms, which are obviously stationary (sessile). So we can rule them out.

Plantae are your traditional plants, which clearly fit neither of the categories, being sessile and phototrophic (they get energy from light, not other organisms.)

Archaebacteria are mostly autotrophs. I doubt they would be considered anyway.

Eubacteria, your traditional bacteria, include cyanobacteria, which are photosynthetic, and other exceptions. I don't think this is what the question is going for.

Protista are essentially the spare parts drawer of the kingdom system. They vary widely in being hetero- or autotrophic, so they certainly don't fit the criteria.

I can only conclude that this question is asking for animalia, which for the most part are heterotrophic and motile. (An exception is the most primitive, sponges or porifera, which are sessile and can't move around, but I expect this is what the question is looking for.) Because heterotrophy and motility are two defining features of animalia, most likely this is what the question is asking. This is a difficult question, because biologists themselves aren't real decided on the right answer.
