The purpose of this study is to determine the experimental group, the control group, the dependent variable, and the independent variable.
Designing and carrying out an experiment is the best approach to prove whether a hypothesis is true or incorrect. To ensure that an experiment examines exactly what the hypothesis claims, scientists must be cautious in how they construct it.
To ensure that only one factor is being altered in an experiment, the independent variables are therefore divided into two groups.
The control groupThe experimental groupThe control group does not experience any changing variable.
The experimental group receives all of the experiment's circumstances, changes as well as the one variable that the experiment is testing.
In Ashley's experiment:
The experimental group:
Seedlings grown with coffee grounds.The control group:
Seedlings grown without coffee grounds.The dependent variable:
Seedling heightThe independent variable:
SoilTherefore, we can conclude that we understand the concept of the experiment carried out by Ashley.

Nitrogen-fixing bacteria are prokaryotic organisms that transform nitrogen gas into nitrogen compounds like ammonia and nitrates.
The graph that correctly shows the nitrogen-fixing bacteria in the soil is graph 2.
Nitrogen-fixing bacteria can be explained as:
Nitrogen-fixing bacteria are the organisms that fix the atmospheric nitrogen into the compounds of nitrogen as ammonia and nitrates.The conversion of the atmospheric nitrogen is done in two steps, the first step involves the conversion of atmospheric nitrogen to ammonia. The second step involves the conversion of ammonium to usable nitrate. Graph 2 represents the amount of atmospheric nitrogen decreasing with an increase in the amount of ammonia. It indicates that atmospheric nitrogen is utilized and converted into nitrogen compounds.
Thus, the correct answer is graph 2.

If the seawater carbonate ion concentration is 250 µmol/kg, a) what is the approximate rate of calcification, and b) approximately how many days would it take 1 square meter of reef to accumulate 30 mmol of calcium carbonate?
a) The approximate rate of calcification = 10 mmol CaCO₃ per m² per day
b) The approximate number of days for 1 m² of reef to accumulate 30 mmol = 0.3 days
a) Determine approximate rate of calcification
making use of the calcification rate map attached when the seawater carbonate ion concentration = 250 µmol/kg the rate of calcification = 10mmol CaCO₃ per day
b) determine number of days
using the relation below
Amount accumulated = Area * rate of calcification * time taken
where amount = 30 mmol
rate = 10 mmol
Area = 1 m²
time = ?
∴ Time = amount / ( Area * rate )
= 30 / ( 10 * 10 )
= 0.3 days

What do you think is the most
dangerous time period for a patient with
CF? Justify your answer.
I think that the most dangerous time period for a patient with cystic fibrosis is;
Age 35 - 44.Cystic fibrosis is a disease that results when there is a malfunctioning of the epithelial cells that line the walls of the sweat glands, lungs, digestive, and reproductive systems.
It causes the skin to taste salty. The patient suffers from shortness of breath and recurrent pneumonia.
In the graph shown, ages 35-44 seem most dangerous for patients with cystic fibrosis because that is the time when the various bacteria that affect the lungs of patients reach their peak and maintain a constant rate.
Therefore, the patients have a high rate of succumbing to the disease during this period.
