The Steller sea lion population has been decreasing in parts of Alaska. New evidence suggests that Steller sea lions need herring as a part of their diet in order to survive. Pollock, another type of fish, also feed on herring. Which would most likely help the Steller sea lion population to increase?

Answers

Answer:

Improving the habitats of herring thereby increasing their population.

Explanation:

First, two consumers (Steller sea lion and  Pollock) are both competing for common prey (herring). Since the question only asked what could be done to increase the decreasing Steller sea lion population of Alaska, the focus would be made only on the Steller sea lion.

The Steller sea lion population would increase if:

1. The herring population should be increased by improving the food available for them to feed on, and improving their reproduction capacities to enable them to reproduce efficiently.

2. Since there are 2 predators. If the population of the prey is fixed, then Pollock should be more hunted by farmers or other biological means to eliminate competition.

A beaker contains three solids: flour, sugar, and baking soda. Whichdescribes the contents of the beaker? *

Answers

Answer: It is a Heterogeneous mixture.

Final answer:

The beaker contains a mixture of three solids, namely flour, sugar, and baking soda. These components retain their properties in the mixture and are not chemically combined.

Explanation:

The contents of the beaker can be described as a mixture. A mixture is a combination of two or more substances that are not chemically combined. In this case, the beaker contains flour, sugar, and baking soda. These are solid substances that maintain their own properties in the mixture. They're simply combined in the same space (the beaker), but they are not interacting on a molecular level to form a new substance.

What is the percent by mass of water in Na2SOa 10H20?total mass of element in compoundUse%Elementx 100molar mass of compoundO 5.59%O 11.26%44.08%O 55.92%

Answers

Molar mass Na₂SO₄. 10H₂O = 322.19 g/mol

Molar mass  H₂O = 18.0

% Element =  molar mass / total mass x 100

% Element = 18 / 322,19 x 100 

% Element =  5.59 %

International System of Units (SI Units) are organized body of measurements for physical quantity. They are set to be the norm or global norm scaling for every physical quantity which includes kilogram, meter, second, ampere, kelvin, candela and mole. These measurements then can increase or decrease by the power of ten, multiplied or divided. As said and explained, the SI is helpful in describing objects because 
1.       They give us the idea of how much matter is contained in that single substance or the current state the matter is in or how hot or cold. We measure and can quantify the quality of the specific matter. 
2.       SI Units are a global set of measurement hence, we can communicate with ease from western to eastern countries with these measurements without having problems in terms of portraying or displaying a set of physical quantities.
