Answer: social and economic
The development of new technologies such as installation of solar panels or the use of geothermal energy to prevent global warming is a social and economic effect. The energy being generated by these processes are useful for human society. This is a social and economic effort done by society in favor of mankind. The energy generated by this process is used in electricity generation and for industrial and commercial needs.
Answer:
The answer is to this question is D.
Explanation:
The situation described in the question is an example of the founder effect. It can be described as "when a small amount of people leave their habitats and form a smaller population elsewhere, there is a decrease in genetic diversity and this change is called the founder effect."
"In a reduced population" in the question points to the founder effect. Although if the reduction of the population is dramatic and immediate, it can also be an example of the bottleneck effect.
I hope this answer helps.
Answer:
B
Explanation:
They all have the same amount of proteins
That would be an example of a decomposer consuming dead organic matter. I hope that answered your question, my friend. :)
Answer:
Concentrations:
1. 12 g salt in 3 L water = 0,4 g salt / 100 ml water
2. 12 g salt in 6 L water) = 0,2 g salt / 100 ml water
3. 30 g sugar in 5 L water) = 0,6 g sudar / 100 ml water
Explanation:
The given data are expressions to deal with the concentration of solutions (a kind of homogeneous mixtures).
There are many forms or units to express the concentrations of the mixtures.
The three cases show mass of solute (salt or sugar) in volume of solvent (water).
One form to express the concentration of the solutions is as mass of solute per 100 mililiters of solvent, which is useful to compare with solutibility tables.
You can do that using the formula:
- (mass of solute in grams / volume of solvent in mililiters) × 100.
To find the concentrations of the given solutions, first you need to convert the volume of the solvent to mililiters (ml):
- 3 L water × 1,000 ml / L = 3,000 ml water
- 6 L water × 1,000 ml / L = 6,000 ml water
- 5 L water × 1,000 ml / L = 5,000 ml water
Concentrations:
1. (12 g salt / 3,000 ml water) × 100 = 0,4 g salt / 100 ml water
2. (12 g salt / 6,000 ml water) × 100 = 0,2 g salt / 100 ml water
3. (30 g sugar / 5,000 ml water) × 100 = 0,6 g sugar / 100 ml water
