I agree to this statement. This is because one organism benefits the interaction and the other organism is neither harm or benefited. This is called as commensalism because human befits from the gray wolf population but they are neither benefited nor harm.
The part of the Human body that is most similar in function to the spongy mesophyll layer in a leaf is A) Alveoli in the lungs.
The cytoskeleton provides energy to cilia
Explanation:
The motion of hair-like structures or axonemes called cilia or flagella are done through sliding movements of one another. This motion needs energy and motor protein molecules called dynein.
Dynein is a cytoskeletal motor protein present in the cytoskeleton and moves in the microtubules and converts the chemical energy in the ATP to mechanical energy to power the sliding and bending movements of cilia.
Apart from facilitating movement, cytoskeleton also contains other proteins which helps it to provide shape and support.
Answer :Erwin Chargaff a Biochemist
Explanation:
He formulated the base paring of double helix of DNA. He reasoned that since the percentage of four DNA bases are of this proportions in human;
Adenine=30.9% and Thymine =29.4%;
Guanine=19.9% and Cytosine =19.8%
Then, the amount of adenine will always be equal to thymine,
And the amount of Guanine equals to cytosine based on this percentages of distribution.
(Adenine and Guanine are large, molecule of Purines, while thymine and Cytosine are Pyrimidine)
He concluded (although scientist believed, he did not explicitly stated this) that this should be the base paring patterns in DNA molecule. This is the first Chargaff Rule.
His second rule is that the DNA composition, in the relative amount of the four bases Adenine, Thymine, Cytosine and Guanine varies in proportion from one organisms to another. And this is the basis of molecular diversity.
