Answer:
- The independent variable is the concentration of sucralose present in the plant.
- The dependent variable is the growth rate of the plant.
Explanation:
The study designed through the steps of the scientific method would be done as follows:
Observation: Sucrose is a very important molecule for the development and growth of plants, based on which sucralose, which is formed from sucrose, can be important for the same factors.
Question: Can sucralose influence plant growth as well as sucrose?
Hypothesis: Sucralose may establish some influence on plant growth.
Experimentation: Select a number of seeds inoculated with sucralose molecules and select the same number of seeds that were not inoculated with anything. Provide the same type of soil and environmental factors so that seeds can grow in the same way. Weekly evaluate the growth of the plants generated by each seed for a certain period of time. After this period of time, measure the weight of the plants and their roots. Place the plant and root to dry in an oven and measure the weight of the plant and root once again.
Analysis of results: compare the average weekly growth of plants generated by inoculated seeds, with plants generated from uninoculated seeds. Compare the average weight of plants generated by seed inoculated before and after kiln-dried. Compare the weight average between plant roots generated by inoculated seeds before and after kiln-dried. Assess whether there was a significant difference between the means.
Conclusion: Using the data presented in the evaluation of the experiment, state whether the hypothesis developed provides true or false information.
<u><em>Note: it is important that the seeds are from the same species of plant.</em></u>
Answer:
This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.
The answer is: 30grams
Explanation:
According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M
Molarity or Molar concentration is calculated using the formula:
M= n/V
Where; M= Molarity (M) = 0.5M
n= number of moles (mol)
V= Volume (V) = 1L
Hence, number of moles (n) = M × V
n = 0.5 × 1
n = 0.5 moles.
To calculate the mass in grams of CH3COOH, we say;
Number of moles (n) × molar mass (MM)
Since atomic mass for (C= 12, H= 1 and O=16)
Molar mass of CH3COOH:
= 12 + 1(3) + 12 + 16 + 16 + 1
Molar mass of CH3COOH = 60g/mol
Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol
Mass = 30grams.
Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.
Producers could not survive without consumers. Produces rely on consumers to purchase their product, if no one buy their product, then the producer has no money to even produce anything. This like a car, the car is the producer, and the gas is the consumer, the car will not work unless there is gas. So a producer will not survive without the consumer.
Inbreeding is simply defined as the mating of relatives. It is a mating system in which individuals carry alleles that originated from a common ancestor. Inbreeding is considered a problem in humans because inbreeding increases the chances of receiving a deleterious recessive allele inherited from a common ancestor.
A group of organisms
aka animals
u can just look this up
its like a group of certain animals
like monkeys but like a whole lot of one kind
