It looks like your answer is luminosity.
According to https://sciencing.com/characteristics-star-5916715.html ,
"Luminosity is the amount of light that a star radiates. The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth."
The answer is B because natural selectionis about the organism that is better suited to its environment. Essentially Survival of the fitest, so B made the most sense to me.
hope this helps fam ✌️
The answer is: Carnivores
Organisms at the third trophic level are secondary consumers. These secondary consumers prey on the primary consumers which are animals that eat plants or herbivores. Secondary consumers are best described as carnivores because they don't eat plants. They only eat animals that consume plants like cows and chicken.
Virus’s are not considered living organisms because:
1. they cannot reproduce by themselves.
2. are structurally very simple.
3. can only be visualized using an electron microscope.
4. typically are associated with diseases.
As the phase changes occur, the freedom of motion of the particles increases.
