there are 5 questions am not sure about...

OpenStudy (abhisar):

Ask

OpenStudy (anonymous):

@Lovelarap post them and I will help

OpenStudy (anonymous):

Which of the following has improved its fecundity? A rabbit that has longer ears A stingray that is well-camouflaged A wood duck with brighter, vibrant coloration than the others A tree frog with a more toxic poison

OpenStudy (anonymous):

i think A

OpenStudy (abhisar):

Ok, Do you know the meaning of fecundity?

OpenStudy (anonymous):

not really... (i stink in bio D :)

OpenStudy (abhisar):

Bio is fun :O

OpenStudy (abhisar):

Fecundity means rate of reproduction!

OpenStudy (anonymous):

that's what my mom tells me.

OpenStudy (anonymous):

the ability to produce offspring frequently and in large numbers. In demography, the physiological ability to reproduce, as opposed to

OpenStudy (anonymous):

soooo that means D?

OpenStudy (abhisar):

So we have to find which of the given adaptations help in increasing rate of reproduction. Let's see each of the options one by one. You may get to learn fun facts.

OpenStudy (abhisar):

Q.1 Why would a tree frog have toxic poison?

OpenStudy (abhisar):

Any guess?

OpenStudy (anonymous):

so it can prevent it's self from preditors?

OpenStudy (abhisar):

Correct!!

OpenStudy (anonymous):

yay

OpenStudy (abhisar):

So if a frog has more toxic poison he would be able to survive their predators well, but it wouldn't necessarily mean increased rate of reproduction.

OpenStudy (abhisar):

Cool?

OpenStudy (abhisar):

Q.2 Why would a rabbit have longer ear?

OpenStudy (anonymous):

it is kinda cool :)

OpenStudy (anonymous):

to hear enemies from far

OpenStudy (abhisar):

Correct! So suppose if a rabbit (the creature in ur pfp) has longer ear than other rabbits he would be able to hear predators from far and thus it will increase his chance of survival. But would it help in increasing repro rate? No!

OpenStudy (abhisar):

Cool?

OpenStudy (anonymous):

definitely!

OpenStudy (abhisar):

Q.3 Why stingray camouflage? What is camouflage?

OpenStudy (abhisar):

brb

OpenStudy (anonymous):

Camouflage is the ability to blend in with your surroundings.

OpenStudy (anonymous):

like chameleons

OpenStudy (abhisar):

I am back...sorry i had to go

OpenStudy (abhisar):

Yes...!!

OpenStudy (abhisar):

So sting rays camouflage iin order to do two things 1) Protect them self from predators 2) To trick their pray But does it help in increasing rate of repro? No!

OpenStudy (anonymous):

ok

OpenStudy (abhisar):

Now million dollar question! What does bright coloration help to wood duck?

OpenStudy (anonymous):

no idea!

OpenStudy (anonymous):

attract males?

OpenStudy (abhisar):

That helps them to attract partner! If a wood duck has better, bright color than others, they will be able to attract partners better and hence will increase rate of repro

OpenStudy (anonymous):

ooohhhhh so it's C

OpenStudy (abhisar):

Yes

OpenStudy (abhisar):

More questions?

OpenStudy (anonymous):

2 more

OpenStudy (abhisar):

Ok let's do them in new post
