Answer:
Unlike typical mammalian red blood cells, those from amphibians, such as frogs, contain a DNA-bearing nucleus that is visible in the center of the cell. The circulatory system of amphibians is rather unusual, their hearts having three chambers, two atria, and a single ventricle.
NegativePositive
Positive
The design of the amphibian circulatory system is curious because blood accumulates oxygen in the lungs and is then returned to the heart before being pumped into the rest of the circulatory system. Therefore, a mixing between oxygenated and deoxygenated blood occurs as blood returning to the heart from the lungs is mixed with incoming blood from the body. Frogs handle this situation by having a very slow metabolism and by absorbing some oxygen through their skin. In addition, the ventricle does have some directional control over the distribution of the blood.
Negative
The presence of a nucleus in amphibian red blood cells allows researchers easy access to large quantities of amphibian DNA. Frog blood has both a solid and a liquid portion. The liquid plasma carries solid elements such as red and white blood cells. Blood can be collected from frogs and the red blood cells isolated by centrifugation. After removal of the residual plasma, purified cells can be treated with specific enzymes and detergents to digest the cellular envelope and release DNA from its protein complex. The DNA is then useful for scientific studies and experiments.

Answer:
i think the answer is A if its wrong im sorry
Explanation:
With the given results, in order for the nurse to identify
the clinical manifestations of diabetic ketoacidosis in which the client would
likely have, she needs to observe the following manifestations such as; rise of
the blood glucose level which beyond the normal range, there is a rapid
breathing which would likely occur that he or she finds it difficult to breathe
normally, there is a presence of pain in the abdomen, excessive need of fluids
as he or she manifest excessive thirst and lastly, his or her results in the
plasma bicarbonate is in the low level. These manifestations could indicate
that the client has diabetic ketoacidosis.
It contributes to global warming by wastage of food produces carbon dioxide which releases more green house gases so the more wastage the more carbon dioxide being released.

Answer:
The dotted line most likely represent C NADH and FADH2
Explanation:
NADH is a reducing agent formed during glycolysis and TCA cycle. FADH2 also act as electron donor or reducing equivalent generated only during TCA cycle.
NADH and FADH2 are reduced form of coenzyme NAD+ and FAD. NADH and FADH2 formed during glycolysis or TCA cycle, enters into the electron transport chain(ETC) to perform oxidative phosphorylation that deals with reduction of oxygen(O2) to water(H2O) along with the formation of energy in form of ATP.
