Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

The EKG is hooked up, and Mr. M's trace looks very abnormal. His heart rate is low. The T wave, which indicates repolarization o

azamat

Answer:

This question lacks options, options are: Mr. M's cells are depolarizing too easily. Blocking Nat channels will make it harder for them to depolarize, bringing their sensitivity back to normal O Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Kt channels can stay open and his cells can repolarize properly. Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Na /K+ ATPase can move Kt out of the cell effectively O Blocking Na* channels cannot help- it will only make his cells fire less, and he already has a weak heartbeat. Mr. M's cells are not repolarizing properly. Blocking Nat channels will help them repolarize normally, bringing their resting potential back to normal.

The correct answer is ''Mr. M's cells are depolarizing too easily. Blocking Na+ channels will make it harder for them to depolarize, bringing their sensitivity back to normal.''

Explanation:

Calcium administration is an emerging treatment modality aimed at restoring the transmembrane electrical gradient of cardiac myocytes. It probably achieves this goal by reducing the resting membrane potential of cells. Calcium antagonizes the effect of hyperkalemia on cardiac conduction, that is, it antagonizes the effects of K on the heart. Its onset of action is immediate, in a few minutes. Calcium gluconate antagonizes the excitability of the cardiac membrane, that is, it decreases the excitability of the membrane and it does not affect serum levels, it is generally accepted that calcium should be administered when there are ECG changes associated with hyperkalemia.

Loop of Henle concentration gradient

nadezda [96]

Answer:

The Loop of Henle serves to create a concentration gradient throughout the nephron which helps increase the reabsorption of water and certain ions. In the thin descending limb, water is very permeable and is reabsorbed due to the existing concentration gradient in the medulla.

At Kroger you can get 6 strawberry and 4 cherry together for $6.90. At Sams Club you can get 5 strawberry and 9 cherry for $9.15

Novay_Z [31]

Answer:

Strawberry = $0.75

Cherry = $0.6

Explanation:

x= Strawberry

Y=Cherry

6x + 4y = 6.9 = -1.5x - 1y = -1.725 x 9 = -13.5x - 9y = -15.525

5x + 9y = 9.15

+ -13.5x - 9y = -15.525

--------------------------------

-8.5x = -6.375

x = $0.75

5(0.75) + 9y = 9.15

9y = 5.4

y = $0.6
