What is a bottom-up systems biology?

The bottom-up approach to systems biology forms detailed models from subunits of data to simulate whole systems under different physiological conditions. To develop an overview of the biological interactions occurring within an organism, various data are integrated into a larger genome-scale model.

What is top-down science?

The top-down approach is a strategy for processing information where a whole system is broken down into component parts, rather than being built up through the contrasting bottom-up approach.

What is a bottom-up approach in science?

A bottom-up approach is the piecing together of systems to give rise to more complex systems, thus making the original systems sub-systems of the emergent system. Bottom-up processing is a type of information processing based on incoming data from the environment to form a perception.

What is top-down sequence?

Top-down sequencing is a MS method of measuring the mass of the intact protein (that is, the “top” part of top-down sequencing ) and then dissociating the gaseous intact protein into product ions (the “down” of top-down sequencing) that allows its sequence to be derived, using software tools.

Is biological evolution top-down approach?

Top-down approach carried out to highlight the direction of evolution of the modern life system into the emergence of life. Molecular evolution would occur in order of biochemical evolution (broken arrow) and biological evolution (solid arrow).

What is top-down and bottom-up biology?

The bottom-up effect means that a lower trophic level in the biological network affects the community structure of higher trophic levels by means of resource restriction [12]. The top-down effect refers to a higher trophic level influences the community structure of a lower trophic level through predation [10].

What is bottom-up vs top-down processing?

Bottom-up processing is when the environment (stimuli) influence our thinking. 2. Top-down processing is when our thinking influences how we see (understand/perceive) the environment.

Is science top-down or bottom-up?

How the Two Approaches Are Different (Yet Complementary) The bottom-up method to data science tends to be unstructured and exploratory. It lets the data lead to a result, while the top-down method defines a problem to be solved and constructs an experiment to solve it.

What is top-down and bottom-up processing?

1. Bottom-up processing is when the environment (stimuli) influence our thinking. 2. Top-down processing is when our thinking influences how we see (understand/perceive) the environment.

What is the difference between top-down and bottom-up implementation quizlet?

Top-down approach is best where there is a dominant program(ex:Law)that is well structured and where the researcher’s resources for studying implementation are limited. Bottom-up approach is best where one is interested in the dynamics of local implementation and where there is no single dominant program.

What is an example of top-down control in ecosystem?

A top-down controlled system focuses on how top consumers influence lower trophic levels. This could be thought of as a predator driven system. One of the classic examples of a top-down trophic cascade is the sea otter story from the Pacific coast. Key players in the food chain are sea otters, sea urchins and kelp.

What is the difference between top-down and bottom-up processing quizlet?

What is the difference between bottom-down and top-down processing? Bottom-up processing is the analysis that begins at the sensory receptors and works up to the brain. Conversely, top-down processing is the analysis guided by higher level mental processes as the brain perceives based on expectation and experience.
