Mr. jones is admitted to the nurse's unit from the emergency department with a diagnosis of hypocalcemia. his laboratory results

<span>The treatment of hypocalcemia depends on the cause ,the severity and the presence of symptoms.Hypocalcemia generally results from another disease process. Most hypocalcemic emergencies are mild and require only supportive treatment and other laboratory evaluation. In this case the nurse will be looking for severe hypocalcemic symptoms like seizures,tetany,refractory hypotensionn and arrythmias.And other laboratory evaluation tests to find whether hypocalcemia is due to some other systemic problem.</span>

one gene in a population of snails determines whether they are poisonous. being poisonous (P) is dominant over not being poisono
Harlamova29_29 [7]

Answer:

F (pp) = 0.04

F (Pp) = 0.32

F (PP) = 0.64

Explanation:

Studying population genetics, we used the Hardy-Weinberg equilibrium model. In the case of snails, the H-W principle predicts that the total number of cases in the population should follow the following equation: PP + 2.Pp + pp = 200.

If a population has 200 snails and 8 are affected by a recessive condition, we have 4% affected, or 0.04.

This means that 0.04 corresponds to p², and p corresponds to 0.2.

Therefore, P is equal to 0.8 because p + P = 1.

Knowing the allele frequencies, we go to the frequency of the genotypes.

F (pp) = p² = 0.04 = 8 snails

F (Pp) = 2.Pp = 0.32 = 64 snails

F (PP) = P² = 0.64 = 128 snails

____________ is a membrane protein that catalyzes the energy requiring synthesis of ATP from ADP and inorganic phosphate.
olasank [31]

Answer:

The correct answer will be option-C.

Explanation:

The production of ATP from ADP and Pi (inorganic phosphate) catalyzed by an enzyme known as ATP synthase.

ATP synthase is made up of two main regions called F₀ and F₁ in which F₀ is embedded in the membrane and acts as a pump through which proton flux takes place. The F₁ unit is the rotating unit of the ATP synthase which rotates due to energy provides by the protons during proton flux.

When proton moves through F₀  unit down their concentration gradient, it provides energy to the F₁ subunits which bind ADP and inorganic phosphate to release ATP.

Thus, Option-C is the correct answer.

What are the stages of mitosis in detail
disa [49]
Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase. In most species, cohesin is largely removed from the arms of the sister chromatids during prophase, allowing the individual sister chromatids to be resolved.

Prometaphase begins with the abrupt fragmentation of the nuclear envelope into many small vesicles that will eventually be divided between the future daughter cells. The breakdown of the nuclear membrane is an essential step for spindle assembly.

Next, chromosomes assume their most compacted state during metaphase, when the centromeres of all the cell's chromosomes line up at the equator of the spindle. Metaphase is particularly useful in cytogenetics, because chromosomes can be most easily visualized at this stage. Furthermore, cells can be experimentally arrested at metaphase with mitotic poisons such as colchicine.

The progression of cells from metaphase into anaphase is marked by the abrupt separation of sister chromatids. A major reason for chromatid separation is the precipitous degradation of the cohesin molecules joining the sister chromatids by the protease separase.

Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells. The daughter cells that result from this process have identical genetic compositions.
