The correct answer is scanning electron microscope and scanning tunneling microscope.  

The SEM refers to a kind of electron microscope, which generates three-dimensional images of a specimen by scanning the surface with a focused beam of electrons. The electrons associated with the atoms in the specimen, generating different signals, which comprise data regarding the composition of the specimen and the surface topography.  

An STM refers to an apparatus for imaging three-dimensional image surfaces at the atomic level. In this, good resolution is regarded to be 0.01 nm depth resolution and 0.1 nm lateral resolution.  

The STM can be utilized not only in a high-ultra vacuum but also in water, air, and numerous other gas or liquid ambient, and the temperatures spanning from 1000 degree Celsius to zero Kelvin.

Ivan

Answer:

The correct answer is D. How closely related the two species are to each other

Explanation:

Genome maps of every individual is unique. Genome map is the order of sequence of nucleotide which is present in an organism. Comparison of genome map allow the scientist to know how much closely related two organisms are.

The map of two individuals of the same species is almost the same. Similarly, the two same species have a more similar genome map than two distantly related species because they share most recent common ancestor.

For example, humans and chimpanzees are more similar than other apes so  96% of the genome are identical between them. So the right answer is D.

Which stage of processing occurs when the stimulus activates one or more sensory receptor nerves, and the resulting sensations g
marusya05 [52]

Answer:

Stage III Interpretation

Explanation:

There are three stages of perception process

• Exposure

• Attention

• Interpretation

During perception, the sensory receptors are active and they receive stimulus from their surroundings.  However, the complete perception of any stimulus is interpreted  by the brain because only brain is capable of differentiating between the sensory stimulus based on the pathway followed by them. On the basis of perceived information, action potential signals are generated that are sent back to the sensory organ (perceiving the stimulus at their end) for further responses.
