The density of a liquid that has a volume and mass is calculated first to understand the mass and density of the liquid.
If 500 mL of a liquid has a density of 1.11 g/mL,
what is its mass?
VOLUME
The density of a liquid may be a measure of how heavy it's for the quantity measured. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is denser.
If a liquid that's less dense than water is gently added to the surface of the water, it'll float on the water.
The degree of loudness or the intensity of a sound also :
- loudness
- the amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters).
Therefore, The density of the liquid is 555g.

Answer:
: If 500 mL of a liquid has a density of 1.11 g/mL, what is its mass? m = d×V = 500 mL × 1.11g1mL = 555 g. VOLUME. d = mV. We can rearrange this to .

Bacterial Population
Time
Which of these most likely explains why the bacterial population stopped growing?
The bacteria mutated from photosynthetic to carnivorous organisms and consumed one another until all the individuals were dead.
The bacteria reproduced in the system but eventually died due to limited resources
The bacteria became diseased and were unable to survive in the closed system
The bacteria competed for nutrients and died after all the nutrients were consumed
Answers
The statement that most likely explains the stop of bacterial populations to grow is the bacteria competed for nutrients and died after all the nutrients were consumed.
What do you mean by Bacterial Growth?
Bacterial growth may be defined as the proliferation of bacterium into two daughter cells, in a process called binary fission.
When there are enough nutrients in the petri dish, a rapid increase is shown in the graph, but during the course of time when nutrients become limited, it affects the growth of the bacterial population.
Therefore, the statement that most likely explains the stop of bacterial populations to grow is the bacteria competed for nutrients and died after all the nutrients were consumed.

Answer:
The answer is "Choice b".
Explanation:
In the given question diagram is missing. so first, we define the diagram after that we explain why the above given choice is correct.
In the attached file the food pyramid can be a divide into the level, in which the D pesticides use the "dichloro-diphenyl-trichloroethane ", which concentration is higher than its entities from the level of A because DDT is transferred with species at level D by levels A, B, and C, that's why the choice "b" is correct.

Answer:
In the population of the study, mutation in the achondroplasia gene is unusually high
Explanation:
In this population, the incidence of genetic mutation that leads to achondroplasia would be 6 children for every 30,000 births. In the general population, achodroplasia has an incidence of 1 per 30,000 births, which indicates that in this specific population, the mutation rate is high above average, which can be explained by a high prevalence of the gene in the population.
Achondroplasia is a genetic disease with inheritance of an autosomal dominant pattern and to suffer from the disease, only one copy of the defective gene is necessary.However, in recent years after several studies it has been possible to demonstrate that even achondroplasia could be generated even in new mutations in the germ cells of the parents.
