Answer:
The correct answer is DNA or RNA. Viral chromosomes exist in a variety of conformations and can be made up of <u>DNA or RNA</u>
Explanation:
The hereditary material of viruses is organized into chromosomes of different types. From the genetic point of view, viruses can be classified into DNA or RNA viruses, double helix or single helix, and circular or linear, that is, viral chromosomes are linear or circular molecules of DNA or RNA. Viruses can be classified according to the type of organism they parasitize in: Bacteriophages or phages, animal viruses and plant-type viruses. Viral chromosomes are also subject to the recombination process, this happens when an individual cell is infected simultaneously by two mutant strains of a virus.
Orthopneic
The client's paroxysmal dyspnea was probably caused by sleeping in bed with the legs at the level of the heart; this position increases venous return from dependent body areas, increasing the intravascular volume. Sitting up and leaning forward while keeping the legs dependent slows venous return as well as increases thoracic capacity. Although the contour position elevates the client's head, it does not place the legs in a dependent enough position to substantially decrease venous return. The recumbent position is contraindicated. Venous return increases when the lower extremities are at the level of the heart. Also, the pressure of the abdominal organs against the diaphragm decreases thoracic capacity. The Trendelenburg position is contraindicated. Venous return increases when the lower extremities are higher than the level of the heart. Also, the pressure of the abdominal organs against the diaphragm decreases thoracic capacity.
Magnitude and direction
Explanation:
A vector quantity has both magnitude and direction. This is different from a scalar quantity that has only magnitude but no direction.
- Examples of vectors are velocity, acceleration, displacement, momentum e.t.c
- These quantities are physical quantities in which their magnitude has specific directions through which they are channeled.
