Answer:

If trees are removed from an area, the environment is negatively effected. Trees are the lungs of this planet because it produces a lot of oxygen and absorbs carbondioxide gas from the environment. One tree produces a lot of oxygen that is enough for 40 peoples. It also provides habitat for millions of species. If trees are removed these species dies and pollution of the environment also increased.

Trees produce oxygen in order for us to breathe. if we cut them down there is less oxygen for us.

in an area of wildlife many different animals survive off of trees. cutting down the trees could lead to the extinction of specific animals.

Suppose that the plasma membrane around a eukaryotic flagellum is opened to reveal the axoneme inside. the radial spokes connect
mash [69]

The flagella of the eukaryotes is composed of the doublet microtubules. The central bundle of these microtubules is known as the anoxeme. In an axoneme, a single pair of the singlet micortubules is surrounded by the nine doublet microtubules. When the plasma membrane of the flagellum is opened to expose the axoneme, and the radial spokes are broken, it will lead to the elongation of the axoneme,

A phenotypic ratio for a dihybrid cross is predicted to be 9:3:3:1. The experimental values are:
Maslowich
Two traits that we are examining are the color (purple/white) and the smoothness. 
In our sample, we have 135 individuals ( 75 +28+24+8= 135).

Since we know that expected ratio of a dihybrid cross, is <span>9:3:3:1 we can calculate what is the expected values of each phenotype is.

So, for the white wrinkled phenotype, we expect that there will be one-sixteenth of the whole sample ( there are 16 parts of the whole sample 9+3+3+1=16).
So, we multiply the whole sample- 135 with one-sixteenth (or </span>0.0625) and get 8,4375.
When you calculate the values for all phenotypes you get results shown in the attached excel table.
When you have your expected and experimental values you compare them with a chi-square test. (The test determines if the difference between the expected and experimental results is statistically significant).
