Answer:
The pesticide measurements were the dependent variable
Explanation:
According to this question, an experiment to determine if pesticide used at local farms was causing fish kills in a local pond was conducted by two students. They followed the following steps:
- Select one location to collect water samples in the pond.
- Collect a 5-mL water sample at 8 am for two days.
- Measure the amount of pesticide present in each sample using the same measurement tools
However, after analyzing the data, they concluded that "runoff from farms is not causing the fish to die in the pond". The students' conclusion is not reliable because THE PESTICIDE MEASUREMENTS WERE THE DEPENDENT VARIABLE.
Note that, the dependent variable in an experiment is the measured variable while the independent variable is the manipulated variable. In this case, the students ought to measure the death RATE OF FISH KILLS as the dependent variable instead. The PESTICIDE is the independent variable of the experiment not dependent variable. This was the reason for the unreliability of the conclusion.

a student observed a food sample that’s left a greasy spot on paper and also gave a positive test for starch. which two organic compounds are present in the food sample ?
Answer:
The correct answer is - fats and carbohydrates are two organic compounds that are present in the sample.
Explanation:
The greasy spot present on paper shows that there are fats present in the food sample that can be butter, ghee, or oil. Fats are the organic compound that provides energy to the organism that eats fat, however, more than a limit fat is harmful to any person.
The starch test suggests that food samples have starch present in the sample, starch is nothing but a polymeric carbohydrate. Carbohydrate is a basic organic compound that provides energy to the body or different organism.
Thus, the correct answer is - fats and carbohydrates.

Answer:500
Explanation:density=mass/volume.
Just substitute 50 and 10 in your equations and you’ll get your answer (mass).
50=m/10
(10)50= m/10 (10)
500=mass
Answer:
500
Explanation:
M=D*V, so 50 times 10.
Which statement about the relationship between the ocean and the rest of Earth's water is true

C. Freshwater sources are connected to each other through evaporation and precipitation.
D. Ocean waters are connected to each other through circulation. Salt water and freshwater are not linked in any way
please help me asap
Answer:
Choice A
Explanation:
The water cycle connects all types of water, since the clouds of sea water or fresh water are moved then become rain somewhere else.
The statement about the relationship between the ocean and the rest of Earth's water is true, is the ocean is connected to all of Earth's freshwater through evaporation and precipitation. The correct option is A.
What is the ocean?About 71 percent of the surface of the Earth is covered by the ocean, a vast body of saltwater. The abundance of water on Earth is truly exceptional.
Water helps link the Earth's lands, oceans, and atmosphere into a cohesive system, which is essential to sustaining life.
The oceans not only contribute evaporated water to the water cycle, but they also permit water to travel throughout the world as ocean currents. Oceans serve as nature's reservoirs for water, which it uses to power the water cycle.
Therefore, the correct option is A. The ocean is connected to all of Earth's freshwater through evaporation and precipitation.
