Answers

Answer 1

Answer:

Explanation:

The presence of the phosphates compound here act as limiting factors for plant growth in aquatic ecosystems, because they do not dissolve easily in water . Then eutrophication( this is the gradual rise in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem.) starts acting wherever there is too much phosphate, it promotes excessive amount of algae and it will exhaust the oxygen.

why are the models of solar systems that you can purchase in stores not to scale?

Answers

Answer:

It's impossible to find a solar system model that is to scale because of how large the solar system is. The solar system is about 287 billion km, making it impossible to purchase or even create a solar system model that is to scale.

The models of the solar systems purchased in stores are not to scale because they are too large to be replicated to scale.

The solar system is a series of planetary bodies which consists of the sun and planetary bodies which orbits around the sun. The solar system is immensely huge with an approximate diameter of about 287.46 billion kilometers.

The entire earth itself has an approximate Circumference of about 40,075 km which is extremely small in comparison to the solar system's diameter.

This means that to produce a model of the solar system to scale, the diameter of the replicated model will be 287.46 billion kilometer which is impossible as it is too large to be replicated to scale even immensely larger Than the diameter of the earth.

What is the range for the following set of measurements?
3.1 mL, 2.7 mL, 4.6 mL, 1.9 mL, 8.7 mL
A. 1.9 mL to 8.7 mL
B. 0.0 mL'to 21 mL
C. 3.1 mL to 8.7 mL
D. 0.1 ml

Answers

Answer:a

Explanation:

1.9 mL to 8.7 mL is the range for the following set of measurements which are 3.1 mL, 2.7 mL, 4.6 mL, 1.9 mL, and 8.7 mL. Therefore, the correct statement is option A.

What is the range?

The range is the difference between the highest and lowest values in a given set of measurements. The range can be calculated from a given set of measurements by subtracting the lowest value which is 1.9 mL and the highest value which is 8.7 mL, thereby, giving a range of 6.8 mL.

In the given set of measurements which are 3.1 mL, 2.7 mL, 4.6 mL, 1.9 mL, and 8.7 mL, 1.9 mL to 8.7 mL is considered to be the range.

Therefore, 1.9 mL to 8.7 mL gives the range of lowest and highest values present in the given set of measurements. However, the range of values cannot be negative and represents the highest and is only represented by the lowest values and highest values in the set.

Therefore, in the 3.1 mL, 2.7 mL, 4.6 mL, 1.9 mL, and 8.7 mL set of measurements, 1.9 mL to 8.7 mL is the range.
