Answer:
The correct answer is A. Intramembranous ossification forms the bones of the roof of the skull.
Explanation:
Intramembranous ossification is one of two types of bone formation and is responsible for the development of flat or laminated bones, especially those in the skull.
This type of ossification occurs within the connective tissue membranes, the so-called primary ossification center. Mesenchymal cells differentiate into osteoblasts. These, in turn, synthesize osteoids (newly synthesized bone matrix), which mineralize, giving rise to osteocytes. Several of these ossification centers happen simultaneously within a connective tissue membrane. Thus, the formed bone beams give a spongy aspect to the bone, allowing the penetration of blood vessels in these formed cavities, originating the bone marrow. The part of the connective membrane that does not ossify becomes the endosteum and periosteum, inwards and outwards.
While bone end-to-end ossification occurs from center to extremity, intramembranous bone develops differently from ossification nuclei, which expand and join over time. The skull, for example, ossifies in this way. For this reason, care should be taken when striking the head of newborns so as not to affect the brain that is not yet fully protected.
Answer:
In the absence of a vaccine, prevention of WNV disease depends on community-level mosquito control programs to reduce vector densities, personal protective measures to decrease exposure to infected mosquitoes, and screening of blood and organ donors.

The nurse should report Hyperkalemia if it occurs immediately after burn injury.
<h3>Hyperkalemia </h3>
Patients with electrical burns have traditionally been thought to develop hyperkalemia as a consequence. The breakdown of red blood cells, rhabdomyolysis, metabolic acidosis, and the onset of renal failure are all contributing factors to hyperkalemia. In this study, the prevalence of hyperkalemia within the first 24 hours following electrical burn injury was examined, as well as any potential relationships between serum potassium concentration and cutaneous burn size (percent TBSA) and serum creatine phosphokinase (CPK) concentration.
First off, hyperkalemia is a rare occurrence in patients who are hospitalized to our burn center with electrical injury along with extensive skin and muscle injuries. Second, whether or not is present is unrelated to the degree of rhabdomyolysis or the size of the burn.

Answer:
Pressure on the head from birth canal
Explanation:
According to scientific findings, the women birth canal is narrow and considered to have muscle, and because of this, during childbirth, the newborn baby while passing through the birth canal, tend to receive a lot of pressure, which can cause the head of the newborn baby to have a shape in accordance to the birth canal.
Hence, in the case, the right answer is "pressure on the head from birth canal" can be attributed to the cone shape of the newborn baby.
