How do artificial and natural selection contribute to biological diversity?
selection processes always reduce diversity. processes modifying genes increase diversity.
How does the storage of energy in ATP molecules benefit a cell?
atp stores energy for maintaining life processes. These life processes result in work being done whenever molecules atoms or ions are rearranged.ATP metabolism is the oldest known cellular metabolism developed by evolution. It may even go back before the existence of proteins, fats, and carbohydrates!
Why is natural variation important when it comes to evolution?
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
How does the geological time influence the theory of evolution?
Geological " deep " time gives ample time for evolutionary processes to occur.
What are the steps are involved in the formation of life on earth include ideas about chemical evolution and biological evolution?
The formation of life on earth has little to do with evolutionary sciences, which deal how lifechanges, not how it begins. The formation of life has as little to do, specifically, with evolution as it does with cell theory, or biogeography, or diet of organisms, or photosynthesis... it's a prerequisite for these processes.
How do artificial and natural selection contribute to biological diversity?
selection processes always reduce diversity. processes modifying genes increase diversity.
How does mutation fit into Darwin's theory of evolution?
It is one of several means of producing diversity on which the several mean of selection that drive evolution can act. Darwin knew nothing of mutation and only discussed diversity (without any mechanism to produce it) and what he called natural selection. There have been many of both types of processes discovered since Darwin.
What processes have shaped the diversity and quantity of life on your planet?
ask powers
What processes led to the evolution of multicellular organisms?
cell differentiation
What is the idea developed by Charles Lyell which states that the geologic processes that shaped Earth in the past continue to operate in the same way today?
The concept of gradualism. Also called uniformtarianism.
Natural processes such as speciation and gradualism provide the genetic basis for what?
evolution
Natural processes such a speciation and gradualism provide the gentic basis for?
evolution
How much natural selection leads to evolution?
All natural selection results in evolution. But natural selection is not necessarily the only mechanism leading to evolution. There are processes at work on a molecular level, such as intragenomic conflict-type processes, that also result in differential reproductive success, but aren't exactly related to the kind of processes Darwin first described.
What principles is not part of Darwin's original theory of evolution by natural selection?
Random processes are not part of the theory of evolution by natural selection.
What are the four processes that lead to evolution?
Mutation, Natural Selection, Migration, and Genetic Drift.
How does geologic and organic evolution compare?
There isn't really such a thing as "geologic evolution". Geology describes processes by which geological features may form or alter, but these are not in any way even remotely similar to the processes by which lifeforms develop over time. The changes wrought by geological processes can be (summarily) described in terms of mechanical forces acting on a single body of mixed composition; the processes involved in evolution require populations of self-replicating organisms. So really, they don't compare. At all.
What molecules exert primary control over basic life processes of all living processes of all living things forming a chemical link between the generations?
water
