Answer:
1,250,000 shrimps per m³
Explanation:
Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;
Population density = population (N)/volume
According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;
Population density of the lake = population of shrimps ÷ volume of lake
Population density = 600,000,000 ÷ 480
Population density = 1,250,000 shrimps per m³
Hi there! It is definitely not a law. A is our. It’s not a hypothesis, because it’s been proven numerous times. B is out. Speaking of which, that leads to theory, which makes sense, because it’s been proven numerous times, and it doesn’t exactly fit the definition of an observation. Theory definitely fits best out of all of these answers. The answer is C: A theory.
The main pigment of plants is "chlorophyll," which gives the green color characteristic of most vegetables, absorbs very well the light in the bands of red and violet, reflecting the green light.
Answer: The correct answer is- D certain factors are dominant and other factors are recessive.
Mendel was interested in knowing the offspring that is produced from the cross pollination (that is from two different plants) as he wanted to study different traits of pea plant.
For doing so, he first removed the anthers of one plant (to prevent self pollination) and then transferred the pollens of one plant into the stigma of another plant.
When he allowed the cross pollination of purebred pea plant with other plant, he observed that some factors are dominant (such as tall height of pea plant, which masks the expression of recessive factors) and other are recessive (such as dwarf height of pea plant).
Thus, option D) is the right answer.
