Answer:

The tree of life refers to a conventional model, which illustrates the origin of Eukaryotes and the relationship amongst the organisms. On the basis of this model, the Archaea and Eukaryotes are the sister lineages, as both descended from the bacterial ancestors.  

On the other hand, the ring of life is a present time model on the basis of which, the emergence of Eukaryotes took place due to the combination of two other domains, that is, Eubacteria and Archaea. The ancestors of Eubacteria and Archaea combined their genomes to produce the initial Eukaryote. That is, two distinct branches of the tree of life were combined to produce the ring of life.

A "ring of Life" is more appropriate to describe the relationship between archaea, bacteria, and eukaryotes than a “tree of life “, because each group of single-celled prokaryotic organisms produces something that is a necessity to another group of single-celled prokaryotic organisms. so therefor it is not like a tree of life which is more of a hierarchy than an everyone, and everything is equal Ring of Life.

Marizza181 [45]
Shortness of breath or difficulty in breathing is also called dyspnea and can be acute or chronic. It has various causes, but mainly can be caused by a problem in the heart or the lungs. Since your heart and lungs are both involved in the transportation of the oxygen to the tissues and the removal of carbon dioxide, any problems occurring to these systems can affect breathing.
B-type Natriuretic Peptide (BNP) reflect the systolic and diastolic activity of the heart and its blood levels can show any heart failure. A BNP test and can help the nurse decide whether the cause of the dyspnea is a heart failure or some respiratory problem.

The normal range of blood glucose is 70–120 mg/dL. A person has a blood glucose level of 170 mg/dL. Based on your knowledge of t
kifflom [539]

Answer:

The normal range of blood glucose is 70–120 mg/dL. A person has a blood glucose level of 170 mg/dL. Based on your knowledge of the endocrine system and hormones, explain the likely cause for the person's condition.

It could be as a result of high sugar intake which increases the individual's blood glucose level

Explanation:

From the assertion above, it could be deduced that the individual pancrease is no more functioning hence; no control of blood glucose level. Furthermore, the continuous intake of sugar or food materials with high sugar content contributes excessively to increase the blood glucose level in the body.

The brain volumes ​(cm cubed​) of 20 brains have a mean of 1116.2 cm cubed and a standard deviation of 127.7 cm cubed. Use the g
Shkiper50 [21]

Answer:

Yes

Explanation:

Range rule of thumb predicts the Range to be  a multiple of 4 of the standard deviation or to be four times  the standard deviation. Making the usual values equal to 2 standard deviations distanct of the mean of the data distribution.

In a given distribution with mean and standard deviation that is obtained, the usual values in mean (as seen in the attached image).

2*standard deviation and mean + 2*standard deviation.

If the data point is not up to the mean

- 2* standard deviation is taken to be significantly low.

If the data point is more than the mean

+ 2*standard deviation is taken to be significantly high.

Let's take the xbar to be the mean and s as standard deviaiton

Given,

mean, xbar = 1116.2

standard deviation, s =127.7

The range rule of thumb shows that the usual values are within 2 standard deviations from the mean

Lower boundary

      = xbar - 2s

       = 1116.2 - 2(127.7)

       = 860.8

Upper boundary

      = xbar + 2s

       = 1116.2 + 2(127.7)

       = 1371.6

We should note that 1411.6 is not between 860.8 and 1371.6, which connotes that 1411.6cm^3 is unusually high.

elena-s [515]

Answer:

A person can have normal chromosomes in number and structure, but still have a disease or condition caused by a mutation in one or more of the genes on the chromosomes. A single gene defect usually does not cause the chromosome structure or number to be abnormal.
