Answer:
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.
That field is called taxonomy (biology)
Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min
Answer:
The correct answer is a. where it reproduce
Explanation:
Lizard is a reptile and salamanders are amphibians and they both reproduce in different way. Female amphibians mainly lay their fertilized eggs in water, therefore, the reproduction in amphibians takes place in water and moist area not on land.
The eggs of amphibians are not covered from the shell and they have a larval stage which have gills to respire in the water. While lizards are reptiles that lay eggs on land because their shells have a protective outer shell of calcium carbonate.
Therefore difference in reproduction behavior best distinguishes the saladizard as either a lizard or a salamander. So the correct answer is a.
