Why is gel used in electrophoresis and what purpose does it serve in separating molecules based on size and charge?
Gel is used in electrophoresis to create a matrix through which molecules can move. The gel serves to slow down the movement of molecules based on their size and charge, allowing for separation based on these characteristics.
How does gel filtration work to separate molecules based on their size and shape?
Gel filtration separates molecules based on their size and shape by passing a mixture through a column filled with porous beads. Smaller molecules can enter the beads and take longer to travel through the column, while larger molecules move more quickly and are eluted first. This process effectively separates molecules based on their size and shape.
A scientist separates a specific protein from all other components of a yeast cell. Next she searches for a small molecule that binds to the isolated protein. What type of experimental design is being?
The experimental design being used is a target-based drug discovery approach. In this approach, the scientist is targeting a specific protein for drug development by isolating it and searching for small molecules that bind to it.
When a system of classification is based on observation of a predetermined set of factors it is called a natural system an artificial system an objective system a subjective system?
When a system of classification is based on observation of a predetermined set of factors, it is called a natural system. This system organizes organisms based on their evolutionary relationships and shared characteristics.
What are the two main types of non cellular synthetic blood products?
The two main types of non-cellular synthetic blood products are perfluorocarbons and hemoglobin-based oxygen carriers. Perfluorocarbons are synthetic molecules that can carry oxygen and carbon dioxide, while hemoglobin-based oxygen carriers are derived from purified hemoglobin to serve as an oxygen carrier in the blood.
Is an empirical evidence the same as a qualitative observation?
No, empirical evidence is based on observation and inference. Qualitative observation is an observation of the qualities of an object. Quantitative observation, on the other hand, is an observation based on some sort of numerical measurement of the object.
Hypothesis it is a--------- based on observation and the knoledge of the topic.?
An hypothesis is a theory based on observation and the knowledge of the topic.
How did the space-based observation of the earth started?
As early as the mid-19th century, early cameras were sent on balloons to observe the Earth from above.
What is the explanation for songs on all Milan that is based on observation experimentation and reasoning?
The science method is all based on the observation experimentation. It is to do different studies.
What is a conclusion based on observation?
Hypothesis
What is an inerence?
A Conclusion or deductions based on an observation.
Is observation a conclusion made based on data?
An observation is a review of what happened. A conclusion is the reselts.
What was the new scientific method based on?
Scientific methods were based on observation and experimentation
What is differrent betweenobservation and inference?
An observation is something that you see or measure. An inference is a conclusion usually based on the observation.
What an interpretation based on observation and prior knowledge?
Hypothesis
A guess about a pattern relationship based on observation?
conjecture
What interpretation based on observation and prior knowledge?
