The right answer is C) vector
In molecular biology and genetic engineering, vectors are DNA molecules that allow the propagation of sequences of interest. These are chimeric DNA molecules such as plasmids or artificial bacterial chromosomes, containing an origin of replication and one or more genetic markers. The origin of replication allows the maintenance of the vector in the target cell during generations.
Dr. Brantz wants to test the part of the brain which is active while lying. For this purpose, he will need to make use of the fMRI (functional magnetic resonance imaging) technique. This technique is used for measuring the brain activity by the means of the detecting changes in the blood flow. The neural activation affects the cerebral blood flow, and this change can be noticed using fMRI.
Hence, the answer is 'fMRI'.
- Analyze: (f) look for relationships of data
- Scientific method: (g) series of steps to solve a problem
- Conclusion: (d) statement based on the results of the experiment.
- Constant: (b) variable that remains the same
- Scientific Law: a) well-tested description of how something works in nature.
- Research: (c) gather information using the library or internet
- Multiple trials: (e) conducting an experiment more than once
Scientific laws explain phenomena that have been proven to be true by the scientific community. In general, theories explain how a phenomenon occurs, whereas laws predict what will happen in a particular scenario based on an equation.
A scientific law foretells the outcomes of particular initial circumstances. It may tell you what color hair your unborn child would have or how far a baseball will travel when launched at a specific angle. In contrast, a theory seeks to offer the most plausible justification for why events take place the way they do.
The five most well-known scientific laws are:
- Bernoulli's law of fluid dynamics.
- Dalton's law of partial pressures.
- Hooke's law of elasticity.
- Fourier's law of heat conduction.
- Archimedes' Principle of Buoyancy.

Answer: cell membrane
such as water, micro-organism
physical process
simple diffusion, osmosis and filtration
such as potasssium permaganate in water,urea a liver waste diffuses from the body and the kidney help in filtering it out
physiological processs
active transport, phagocytosis and pinocytosis
such as soduim-potassium pump, exocytosis
Explanation: transportation in and out of cell is done in different ways listed above but a barrier to this movement is the cell membrane which is an outer covering of the cell. it protect the cell and only some materials can penetrate the cell membrane e.g micro-organism, water e.t.c. the various physical and physiological processes are the various ways substance cna be liquid, solid or gas are transported within or outside the cell e.g food
