Chap wanted to see if planting seeds deeper into the soil had an effect on plant height. He took ten containers and planted radish seeds at varying depths. He used the same type of soil, kept the plants in the same location, and gave them each 20 milliliters (mL) of water each day. Then, he measured the height of the sprouts every day for two weeks. What are the independent (test) and dependent (outcome) variables in Chap's experiment?
Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.
how are elliptical galaxies diffrent from spiral galaxies
Answer:
While spiral galaxies are bright, elliptical galaxiesare dim. Spiral galaxiesare hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born.

Answer:
The first box would be the pH will decrease, and the acidity will increase, and for the second box, the pH will increase, and the acidity will go down.
Explanation:
As the hydronium concentration increases, the pH decreases, and therefore if the hydromnium concentration decreases, the pH will increase. pH is sort of backwards, as the level increases, the acidity will go down, and as it decreases, the acidity will go up.

Precipitation is one of the main processes involved in the water cycle. It involves the formation of water falling to the ground from clouds and transforming into either rain, snow, sleet, or hail. Which of the following properties of water can be used to explain why when water falls from clouds it is able to form a rain drop? *
A. cohesive ability
B. universal solvent
C. expansion upon freezing
D. moderation of temperature
Answer: A
Explanation: Hydrogen bonds between the water molecules on the liquid surface are relatively strong and pull on each other more than air molecules. This bond strength results in surface tension that tends to minimize the liquid surface area and produce a spherical raindrop.
Precipitation is the one of the main processes in the water cycle. It involves the formation of clouds and transforming into either rain, snow, sleet, or hail. This is possible due to the property of cohesive ability of water molecules. Thus, the correct option is A.
What is Precipitation?
Precipitation is one of the main processes involved in the water cycle. It is the liquid or frozen water which forms into the atmosphere and falls back to the Earth in the form of rain, sleet, snow, or hail. It comes in many different forms. Along with the evaporation and condensation of water, precipitation is one of the three major parts of the global water cycle.
Precipitation is achieved by the cohesive ability of the water molecules which explains the formation of clouds and rain drops. Cohesive forces are responsible for binding the compounds together such as a rain drop containing water molecules.
Therefore, the correct option is A.

Which of the following indicates that an endothermic reaction has occurred?
O Heat is released
O water is formed
O Salt is produced
O Temperature decreases
The following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.
What is the significance of the endothermic reaction?There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.
Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

A certain chocolate bar contains 6 mg of caffeine in a 1.5 oz. Serving. The king-size version of the chocolate bar is 85 grams. How much caffeine, in mg, would you consume if you eat the entire king-size bar?Fill in the answer in the blank provided. Mg of caffeine
Answer:
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg
Explanation:
This question can be reframed in the manner below for better understanding.
If 1.5 oz or ounce of a chocolate bar contains 6 mg of caffeine, how many milligrams (mg) of caffeine is contained in 85 grams of the same chocolate bar.
Firstly, the ounce should be converted to grams
If 1 ounce = 28.35g
1.5 ounce = ?
= 1.5 × 28.35/1
=42.53g
Hence, 42.53g of the chocolate bar contains 6 mg of caffeine
85g of the chocolate will contain
42.53g = 6mg
85g = X
where X is the amount of caffeine that will be consumed in mg
X = 85 × 6/42.53
X = 11.99 mg
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

Repeat the demonstration on a paved surface such as a driveway or sidewalk and document the differences. With no soil to absorb this water, what would happen in a heavy rainstorm? How would an engineer in charge of a city's flood control system prepare for the runoff generated on paved parking lots and roads in a heavy rainstorm?
Answer:
Explanation:
Without soil to absorb the excess water, a heavy rainstorm will cause massive flooding. The water will accumulate over the pavement and keep rising until it finds soil or a runoff since water always levels itself out. To prevent situations such as this one an engineer should implement drainage tunnels between the road and the sidewalks. This would allow the water to be drained and flow to the nearby body of water. This would easily prevent flooding during a heavy rainstorm.
Answer:The rate of absorption into the soil was very slow, which meant that some of the water flowed over it and was either absorbed in a different area, or ran onto the driveway and down into the street. It was a warm sunny day, so after a while the wet patch of water on the sidewalk had dried up (evaporation). Once the soil got wet from absorbing the water, the rate of absorption got even slower – like the soil was “full” – and more water ran over onto the driveway. The water on the driveway moved very quickly, since the concrete didn’t absorb it. Our street has never flooded before, but I have seen heavy rainstorms where the water was moving down the street like a big stream, carrying fallen leaves and trash down into the storm drains.

Explanation:
. If a suggested daily protein consumption of .8 grams / Kg. Body weight is recommended, how many protein Kcals would be represented in the diet of a 220 lb. Individual with no suggested health concerns or limitations? (Kgs. = lbs. / 2.2 ; The caloric density of protein is 4 Kcals / gm.)
Answer:
The correct answer would be - 320 kcal.
Explanation:
Given:
Required protein amount is - .8 grams/kg
kg = lbs/2.2
weight = 220
then, weight in kg = 220/2.2 = 100 kg
solution :
requied amount of protein in normal individual:
= 100* 0.8
= 80 grams.
Now kcal by this amount of protein would be :
= 80*4
= 320 Kcal
Thus, the correct answer would be - 320 kcal.
The amount of protein Kcals in the individual's diet would be 320 Kcals.
The recommended daily protein consumption = 0.8grams / Kg body weight
The body weight of the individual is given as 220 lbs.
The weight of the individual would need to be converted to Kg.
Conversion factor between Kg and lbs is given as: 1 Kg = 2.2 lbs
The weight of the individual in Kg = 220 lbs * 1 kg /2.2 lbs ) = 100 kg
Amount of recommended protein intake of the individual based on body weight will be: 0.8 grams/ Kg * 100 Kg = 80 grams
Caloric density of protein per gram = 4 Kcals / gram
Therefore, protein Kcals in the individual's diet will be 4 Kcals / gram * 80 grams = 320 Kcals
The amount of protein Kcals in the individual's diet would be 320 Kcals.
