In 1973, biologist Theodosius Dobzhansky wrote an essay titled "Nothing in Biology Makes Sense Except in the Light of
Evolution." Why is evolution so important for understanding biology? Explain your answer in 1-2 sentences. (2 points)
Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
What is the purpose of the theory of evolution?The Theory of Evolution states that it is the environment, through natural selection, that determines the importance of the individual's characteristic or its variations, and the organisms best adapted to this environment have a greater chance of survival, leaving a greater number of descendants.
With this information, we can conclude that Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.

Suppose the stereocilia of one hair cell become permanently bent toward the kinocilium. What will most likely happen as a consequence
Answer:The options are not given, here are the options from another website.
a. A single pitch will be constantly perceived
B. A single pitch will no longer be perceivable
c. A or B depending on the hair cell's location
d. A or B depending on the bending's direction.
The correct option is d.
A or B depending on the bending's direction
Explanation:
This is because stereocilia are normal bent where there is a shearing force that occur when there is a up and down movements of the basilar membrane . When stereocilia bend towards the kinocilium, it make it depolarizes the cell and lead to the afferent activity to rise up and when the stereocilia bend away from the kinocilium , it hyperpolarizes the cell and lead to a reduction in afferent activity.
The consequences of this are that a single pitch will be noticed, or no pitch will be noticed. This will depend on the direction the stereocilia have bent.
We can come to this answer because:
Stereocilia are cellular accessories that help cells move around.They can curve up or down, generating different but very important effects.If the curvature is made towards the kinocilium, we can notice the formation of a pitch, as the cell becomes polarized.If the curvature is in the opposite direction to the kinocilium, the cell will be depolarized and it will not be possible to visualize the pitch.In this case, we can state that the consequences of the curvature of the stereocilia will depend on the side towards which this curvature is directed.

Which characteristic could help you distinguish between types of fungi
Answer: The correct answer would be the spores made by the fungi.
The major phyla of the fungi are usually classified on the basis of characteristics of sexual structures.
For instance, the chytridiomycota produce zoospores, the blastocladiomycota undergo sporic meiosis, the ascomycota forms ascospores et cetera.
Fungi are mainly classified into seven phyla:
Microsporidia
Chytridiomycota
Blastocladiomycota
Neocallimastigomycota
