Question: What effect will adding soap to water have on surface tension?
Hypothesis: If, soap is added to the water slowly dropped on a penny then, the penny will hold more water.
Independent/Dependent/Control Variables: Independent: the amount of soap/oil; Dependent: the penny; Control: amount of oil/water given
Materials: 3 cups, water, canola or olive oil, dish soap, a pipette and or needle/syringe, pennies
Procedure:
· Gather three identical cups
· Add water to the first one (1/3 cup of water in each), add water and soap in the second one, and olive or canola oil in the third.
· Lay out three pennies.
· Take pipette and slowly bring water in from cup #1, drop onto penny until water falls over, record results of how many drops it took.
· Repeat with cup numbers 2-3 and record information/data.
Data/Observations: With the regular water on a penny, I noticed that only 13 regular drops could fit on without falling over.
With the water+soap, it got up to 24 drops before falling over. Then on the 25th drop, the mixture fell off.
With the oil, it was the highest at 29 drops before falling over slowly. Therefore, oil holds the most surface tension in this experiment.

In a population of tree frogs, the allele that causes yellow eyes (Y) is dominant over the allele that causes orange eyes (y). If 85% of frogs have yellow eyes, what is the frequency of the dominant allele?
Hardy-Weinberg Principle
Genotype frequency equation
[tex] p^{2} +2pq + q^{2} = 1 [/tex]
Where p² is the freq of homo dominant genotype, 2pq is the freq of heterozygous genotype and q² is the freq of homo recessive genotype.
Allele frequency equation
p + q = 1
Where p is the frequency of dominant alleles and q is the frequency of recessive alleles.
Yellow eyes in the frog offspring is a phenotype (physical trait) that would be a expressed by a geneotype (YY or Yy). This frequency, 0.85 includes: p² + 2pq
0.85 + q² = 1
q² = 0.15
p = [tex] \sqrt{0.15} [/tex]
Then p + [tex] \sqrt{0.15} [/tex] = 1
1 - [tex] \sqrt{0.15} [/tex] = p
p = 0.613

C. Mining asteroids
D. Creating more fossil fuels
Creating more fossil fuels is not being used or researched to help address the issue of overuse of resources.
Explanation:The practice that is NOT being used or researched to help address the issue of overuse of resources is Creating more fossil fuels. In the quest to address resource overuse, creating more fossil fuels isn't a viable practice or subject of research. The focus, instead, revolves around sustainable alternatives to reduce reliance on finite resources. Efforts prioritize renewable energy sources like solar, wind, and hydroelectric power, promoting efficiency, recycling, and implementing eco-friendly technologies. Research aims to develop innovative methods for conservation, promoting circular economies, and fostering behavioral shifts toward responsible consumption. Creating more fossil fuels contradicts the imperative to mitigate environmental impact and climate change, aligning poorly with sustainable resource management strategies crucial for our future wellbeing.
Final answer:
OPTION D
Creating more fossil fuels is not a practice being used or researched to help with the overuse of resources. Instead, efforts are focused on reducing reliance on fossil fuels and improving renewable energy sources and more sustainable practices like desalination, genetic modification of crops, and potentially mining asteroids.
Explanation:
Overuse of resources is indeed a critical issue affecting sustainability and future generations. To mitigate these concerns, various practices have been implemented or are presently being researched. Desalinating water (A) is a process used to make sea water drinkable, which helps preserve freshwater sources. Genetically modifying food (B) can lead to crops that are more resistant to pests and changing climate conditions, ultimately improving food security. Mining asteroids (C) is being explored as a way to acquire minerals and other resources without further depleting Earth's reserves.
However, creating more fossil fuels (D) is not a practice being used or researched to help with the overuse of resources. The use and extraction of fossil fuels have significant environmental impacts, including habitat destruction and climate change due to excessive greenhouse gas emissions. Instead, there is a focus on reducing reliance on fossil fuels and increasing the use of renewable energy sources that do not produce carbon dioxide as a by-product.
