Answer:
Option D, at the branch tips
Explanation:
Phylogeny tree is just like a family tree in which the roots of the tree that are its base represents the ancestral lineage. While moving towards the branches , the time is considered to be moving forwards as the organism which lie at the tip of the branches are the ones which have evolved from the ancestral lineage lying at the base. Thus, the branches at the end of a tree are the ones which have the most recently evolved organism.
Thus, option D is correct
Answer:
i believe C
Explanation:
the layers propose a volcanic eruption along with the crystals such as how an agate forms.
You use inductive reasoning to propose a process that explains observed facts. You use deductive reasoning to propose what facts you would observe if a known process took place.
Deductive reasoning, or deduction is a type of reasoning used in scientific method. It starts out with a general statement (called hypothesis is scientific method), and examines the possibilities to reach a logical conclusion about it. If the theory is correct, what observations should be. Inductive reasoning is the opposite. It is a type of reasoning when you start from specific observations to the general statement.
Answer:
Myelination
Explanation:
Myelin is a fatty substance composed of lipids which surrounds the axons of the nerve cells in the central nervous system. The myelin is formed by the oligodendrocytes in CNS and Schwann cells in PNS.
The plasma membrane of the oligodendrocytes containing the myelin covers the axons of the neurons in spiral fashion thus proving a sheath around through the process called "myelination".
This myelin sheath protects the neurons from the external environment as well as insulates the neuron which increases the efficiency of the impulse.
Thus, Myelination is the correct answer.
