This article was about the discovery of a odd Bird that had two tails. Scientist think that the bird used one of the tails for flying and the other one for show. scientist called this bird Jeholornis. The scientist thought that because some male birds have striking plumages witch is a bird's feathers collectively, so they think that this bird only had to tails if they where mail birds.










My opinion is that I liked that scientist are still discovering and studying creatures that no longer live because it could help understand new stuff that pops up in the presents. I feel that this discovery will be useful if another type of two tailed creature pops up they will be able to understand the next creature thanks to the discovery of the Jeholornis.

Why Do Leaves Chang Colors

 

He guys I'm back and today I Will be talking about why leaves change coler. A lot of people have different answer and I will tell you some of them. lets go!

 

 

 

 

 

 

 

 

 

I Don't cause it!!!!!!!




There are a lot of rumors of the changing of leaves like for example some people think that the proses is effected by the weather.  Another rumor is that the time of the year which is part of the answer. Some people just thinks it happens. None of these answer are correct. Just like other things in the world there is a reason that this is happening.








This proses could not happen without the chloroplast or the chlorophyll. When it starts to get to Autumn the days start to get shorter and the leaves aren't getting enough sunlight. When they don't get enough sunlight they start to shut down the leaves and the chloroplast aren't making the plants green showing the leaves true color., Yeah. When it is near autumn tree's will stop producing chlorophyll. This happens because the days are shorter. Some of the trees don't lose there leaves because they have adapted to the amount of sunlight.















Carotenoids and Anthocyanin's are the color over masked by the chlorophyll. Some examples of fruit are apples, peaches, and pears. The time of the chlorophyll being gone.
