The client with chronic kidney disease and congestive heart failure is weak and dyspneic. Lab work reveals a hemaglobin of 6.5 g
inysia [295]

Answer:

packed RBC

Explanation:

  • Packed red blood cells consist of red blood cells that are separated from the rest of the blood components and are used for transfusion.
  • When the hemoglobin of a person falls below 70–80 g/L (7–8 g/dL), then the person is usually transfused with packed RBC.
  • In the given situation, the client has chronic kidney disease and congestive heart failure and as a result of this, the hemoglobin levels of the client has fallen down 6.5 g/dL (65 g/L) and thus, there is an immediate need for the provider to perform a transfusion of packed RBC of appropriate blood type as RBCs are a carrier of hemoglobin in the body.

What is the advantage of radial symmetry for sessile animals such as hydras and bilateral symmetry for mobile animals such as pl
Juliette [100K]

Answer:

- Radial symmetry is advantageous because sessile animals can "sit down", take food, or sense harmful environmental conditions from different directions.  

- Bilateral symmetry allows motile animals to move straight forward.

- The major evolutionary advantages of bilateral symmetry include cephalization, the formation of a head and tail area and a more directional motion.

Explanation:

Radial symmetry is advantageous for sessile organisms since it enables the uniform distribution of the sensory receptors around the body. In consequence, sessile organisms can react to environmental stimuli from every direction. On the other hand, bilateral symmetry allows motile organisms the arrangement of a specialized nervous system from the anterior end of the organism (i.e., the 'head'). Moreover, another important advantage of bilateral symmetry is the ability to equalize environmental pressures on both sides of the body, thereby enabling a rectilinear motion.

skelet666 [1.2K]
Diploid cells are like daughter cells coming from a mother cell called a haploid cell. So the more daughter cells are born, the greater the chance of getting hybrids and creating more diversity on the genetic races existing. In this case, the answer would have to be honeybees.
