Correct Completed Questions; Susan, a 67 year old female is experiencing ataxia, or poor muscle coordination. Doctors perform a neurological exam and they find that Susan is not positive for the Romberg test. Describe what these findings suggest about the sources of Susan's ataxia.
Answer:s
In order to test for balance and positioning(proprioception) as a measure of neurological function, or to test level of intoxication alcohol during driving, Romberg test is usually conducted,which can be negative or positive.It is generally used to investigate the cause of loss of motor control in individuals.
Explanation:
A positive result showed that her ataxia was due to loss of positioning due to loss of sensory from sensory neurons.However if negative as in the case of Susan, then it is to due to abnormality/dysfunctions in the cerebellum, and not due to loss of sensory functions,
Answer:
Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules.
Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.
Explanation:
The answer is A.The calcium atom must bond with an atom of high electronegativity (like fluorine) because the higher electronegativity atom will bully the low electronegativity atom and take away its electrons.
These are the choices:
A. an atom with a high electronegativity, like fluorine
B. another atom with a low electronegativity, like lithium
C. another atom that would like to share electrons
D. no other atoms because it's too weak to bond with anything
