Researchers plotted a distribution curve for leg length in a population of birds, with length from short to long on the x-axis. The curve shifts to the right after a disturbance. Which statement is correct about natural selection in this population of birds?
Birds with long legs were selected for.
Birds with long legs and birds with short legs were selected for.
Birds with medium-length legs were selected for.
Birds with short legs were selected for.
In peppered moth populations, light and dark moths are selected for in different environments. Which type of selection is this, and what would a distribution curve for all peppered moths look like?(1 point)
disruptive selection; a tall, narrow peak in the center of the graph
stabilizing selection; a tall, narrow peak in the center of the graph
disruptive selection; two peaks at the extremes of the graph with a dip in the middle
stabilizing selection; two peaks at the extremes of the graph with a dip in the middle
Over generations, female reindeer in a Finnish population give birth to larger offspring. Which type of selection is occurring, and how would a distribution curve for this trait change over time?(1 point)
stabilizing selection; the curve would become shorter in the middle
directional selection; the curve would shift to the left
stabilizing selection; the curve would become taller in the middle
directional selection; the curve would shift to the right
In a population of mice, individuals with medium brown fur are less likely to be seen by predators than light brown and dark brown mice. What type of selection is this, and what would the distribution curve for the mouse population look like?(1 point)
disruptive; a tall, narrow peak in the center of the graph
stabilizing; a tall, narrow peak in the center of the graph
stabilizing; two peaks at either end of the graph with a dip in the middle
disruptive; two peaks at either end of the graph with a dip in the middle
Paleontologists observed changes in the sizes of black bears as their environment changed. During warmer periods between ice ages, most black bears were small. During ice ages, most black bears were large. Which type of selection is this, and how would a graph of the distribution curve of black bear size change as Earth moved out of an ice age?(1 point)
directional; the curve would shift to the right
stabilizing; the curve would become taller in the middle and shorter on each side
directional; the curve would shift to the left
disruptive; the curve would break into two peaks with a dip in the middle
1. C-Birds with long legs were selected for.
2.C-disruptive selection; two peaks at the extremes of the graph with a dip in the middle
3. B-directional selection; the curve would shift to the right
4. C-stabilizing; a tall, narrow peak in the center of the graph
5.C-directional; the curve would shift to the left
1. Birds with long legs were selected for.
2.disruptive selection; two peaks at the extremes of the graph with a dip in the middle
3. directional selection; the curve would shift to the right
4. stabilizing; a tall, narrow peak in the center of the graph
5.directional; the curve would shift to the left
is this right???
ima check
yes just took the quick check
YES @Some who helps IS CORRECT
This website never lets me down
They're right
hi dad
1. Birds with long legs were selected for.
2. DISRUPTIVE selection; two peaks at the extremes of the graph with a dip in the MIDDLE
3. DIRECTIONAL selection; the curve would shift to the RIGHT
4. STABILIZING; a tall, narrow peak in the center of the GRAPH
5. DIRECTIONAL; the curve would shift to the LEFT
Have an amazing day!
(I capitalized keywords to help you find the answer!)
Someone who helps is right but the letters are wrong but the words are right.
no help from my dad
Don't go by just the letters bc they change the order of the answers a lot. Look at the people who write out what the answer says and go by that. That will get you the best grades : )
bob jr is right. ty
Ok, seriously stop using letters for answers on LA and science, the order is automatically randomized.
lol mine or 45 questions-
Yeah I mean other students have said that before that connexus switches up the answer 😐
Someone who helps is correct. Thank you so much for the quick check. I got a 100% on it. The answers are: 1. birds with long legs were selected for. 2. disruptive section; two peaks at the extremes of the graph with a dip in the middle. 3. directional section; the curve would shift to the right. 4. stabilizing section; narrow peak in the center of the graph. 5. directional section; the curve would shift to the left. This is for the Mathematics of Natural selection quick check for science grade 7th in Connexus. 📝📖👍😎
@some who helps is a btc :) but he correct
some who helps and bob jr are right
Someone who helps 100%!!!
im gonna go missing next month
wait nevermind
@Some Who Helps is correct but the last question??
hey @thanks i got 0%
There's a reason we don't do this. The answers´ letters are changed around. the answer could be A one time, then D the next. It isn't that hard to read through some of these.
got 100%
cap
UwU
Please don't say things like that. If you are feeling sad or overwhelmed, please talk to someone. There is always someone who can help you.
Yea mines a unit test..
mine is a unit test 14 questions
bro just put B C OR D its annoying to read through all of this
Some who helps is bad at this
