In a closed system, the total energy prior to an energy transformation is _______ the total energy after. A. equal to B. unrelat
nikklg [1K]
Hey there mate!

Based on my information to this, I believe sense (it would be a closed system), this would most likely be considered to be (equal to) the total energy after.

But, if it was not a (closed system), it would not be unrelated because the energetic system would not be that greatly increased.

So, it really depends whether the system closes up, or whether it would be free of energy.

So, in this case, your correct option to this answer would be (option A).

<span>In a closed system, the total energy prior to an energy transformation is unrelated to the total energy after. 

I hope this helps you!</span>

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,

You breed a plant that has purple flowers with a plant that has orange flowers and the resulting offspring has purple and orange
gayaneshka [121]

Answer:

Incomplete dominance

Explanation:

Incomplete dominance is the expression of phenotype of two paired alleles (i.e dominant and recessive allele) all together.

Usually when two alleles get paired, the characteristics of the dominant allele is expressed while the characteristics associated with recessive alleles are expressed only when the two recessive allele get paired.

Here in this case the characteristics of both type of allele are expressed i.e. both orange and purple strips appear in the offspring. Hence, this case shows the incomplete dominance.
