1) The control /constant in this experiment is the fifth group of plants that are not exposed to any pollutants.

2) The dependent variable is the condition and growth of the plants.

3) The independent variable is the exposure of the plants to various pollutants.

4) The variables are quantitative because they can be measured.

5) Possible sources of unavoidable experimental error include the type of pollutants used, the amount of pollutants used, and the exposure time of the plants to the pollutants.

Further explanation of concepts:

What is a control variable?

A control variable is a variable that is kept constant in an experiment. Keeping the variables constant allows the experimenter to see the effects of the manipulated variable on the dependent variable. In order to control variables, the experimenter must use a controlled experiment. A controlled experiment is an experiment in which only one variable is changed while all other variables are kept constant.

What is a dependent variable?

A dependent variable is a variable that is being measured in an experiment. The dependent variable is the variable that is affected by the independent variable.

What is an independent variable?

The independent variable is the variable that is affecting the dependent variable. For example, in an experiment to test the effect of different fertilizers on plant growth, the independent variable would be the type of fertilizer used. The dependent variable would be the plant's growth.

Quantitative vs qualitative variables

Quantitative variables are variables that can be measured. Qualitative variables are variables that cannot be measured. Quantitative variables are usually numeric, while qualitative variables are usually non-numeric.

The dilution factor in order to end up with 96 colonies of bacteria is 0.23 × \(10^6\) .

For calculating the colony forming unit bacteria;

Colony-forming unit (CFU or cfu) is a measurement of live bacterial or fungi cells and is used to calculate the colony-forming unit of bacteria. CFU counts only viable cells as opposed to direct microscopic counts, which count all cells, both living and dead, using a hemocytometer. Colony-forming units per milliliter (CFU/mL) for liquids and colony-forming units per gram (CFU/g) for solids are used to indicate the results for convenience. The miles and Misra method can be used to compute CFU, which is helpful for assessing the microbiological load and severity of illness in blood and other samples.

∴ cfu/ml = (no. of colonies x dilution factor) / volume of culture plate

  23 x \(10^6\) cells per mL          =  96 × dilution factor

  Dilution factor  = 23 ×\(10^6\) / 96

  Dilution factor  = 0.23 × \(10^6\)

Therefore, the dilution factor in order to end up with 96 colonies of bacteria is 0.23 × \(10^6\) .

Answer:

The answer is in the picture.

Hope this helps!

Explanation:

The distributions of the random variables in the given scenarios are (a) binomial for the water lizards and (b) Poisson for the health center visits. The probabilities can be calculated using the respective formulas for the corresponding distributions.

(a) The distribution of the random variable X, which counts the number of water lizards out of the 25 selected with webbed feet, follows a binomial distribution.

This is because each lizard can be considered as a Bernoulli trial (success: possessing webbed feet, failure: not possessing webbed feet) with a probability of success (p) equal to 61% or 0.61, and the trials are independent.

(b) To compute the probability that exactly 17 of the 25 selected water lizards have webbed feet, we can use the binomial probability formula.

The probability mass function (PMF) for the binomial distribution is given by P(X = k) = C(n, k) * p^k * (1-p)^(n-k), where C(n, k) represents the number of combinations of n items taken k at a time. Plugging in the values, we have P(X = 17) = C(25, 17) * 0.61^17 * (1-0.61)^(25-17).

(c) To compute the probability that at least 17 of the 25 selected water lizards have webbed feet, we need to calculate the cumulative probability from 17 to 25. This can be done by summing up the probabilities for each value of X from 17 to 25: P(X ≥ 17) = P(X = 17) + P(X = 18) + ... + P(X = 25).

(d) The mean (μ) and standard deviation (σ) for the number of water lizards out of 25 who have webbed feet can be calculated using the formulas for the binomial distribution.

The mean is given by μ = n * p, where n is the number of trials (25) and p is the probability of success (0.61). The standard deviation is given by σ = sqrt(n * p * (1-p)).

Moving on to the second scenario:

(a) The distribution of the random variable X, which counts the number of patients that visit the health center during a randomly selected week, follows a Poisson distribution.

This is because the number of patients per week can be modeled as a Poisson process, where events (patient visits) occur independently and at a constant average rate (300 patients per week).

(b) To compute the probability that exactly 310 patients visit the health center during a randomly selected week, we can use the Poisson probability formula.

The probability mass function (PMF) for the Poisson distribution is given by P(X = k) = (e^(-λ) * λ^k) / k!, where λ is the average rate of the Poisson process (300 patients per week) and k is the number of events we are interested in (310 patients).

(c) To compute the probability that more than 280 patients visit the health center during a randomly selected week, we need to calculate the cumulative probability from 280 to infinity. This can be done by summing up the probabilities for each value of X from 280 to infinity: P(X > 280) = P(X = 281) + P(X = 282) + ... + P(X = ∞).

Feedback loops play an important role in regulating the action of hormones in the body. Hormones are signaling molecules that are released by various glands in the body and they travel through the bloodstream to target cells where they bind to specific receptors and cause a response. The feedback loop is a mechanism by which the body maintains the balance of hormones in the bloodstream.

There are two types of feedback loops: positive and negative feedback. In a negative feedback loop, the body detects an increase or decrease in the hormone levels and responds by decreasing or increasing the production of the hormone, respectively.

For example, when the blood glucose level rises, the pancreas releases insulin to lower the glucose level. Once the glucose level reaches a certain level, the pancreas stops releasing insulin.

In a positive feedback loop, the body amplifies the response to a stimulus. This type of feedback loop is less common in hormone regulation.

An example of positive feedback in hormone regulation is the release of oxytocin during childbirth. Oxytocin causes contractions, which then stimulate the release of more oxytocin, leading to stronger contractions until the baby is born.

Overall, feedback loops are crucial for hormone regulation in the body. They help to maintain the balance of hormones and ensure that the body responds appropriately to changes in the environment or internal conditions.

DNA is more stable than RNA because thymine forms more stable hydrogen bonds than uracil, RNA can have secondary structure, and the presence of the 2'OH group on RNA makes it less stable compared to DNA.

DNA is more stable than RNA due to several factors. Firstly, thymine, which is present in DNA, forms more stable hydrogen bonds with adenine compared to uracil, which is found in RNA. The hydrogen bonds between the base pairs contribute to the stability of the double-stranded structure of DNA.

Secondly, while RNA can form secondary structures, such as hairpin loops, DNA is more commonly associated with stable secondary structures like double helices. The presence of secondary structures allows DNA to maintain its stability and protect the genetic information it carries.

Lastly, the presence of a 2'OH group on the ribose sugar of RNA makes it more prone to degradation compared to DNA. This 2'OH group can participate in intramolecular reactions, increasing the vulnerability of RNA to chemical degradation and enzymatic attack.

In conclusion, DNA is more stable than RNA due to the more stable hydrogen bonding ability of thymine, the presence of stable secondary structures, and the absence of the 2'OH group in DNA. These characteristics contribute to DNA's ability to store and transmit genetic information with high fidelity.

Answer:

Carbon dioxide; lower than.

Explanation:

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Radiation is simply the transmission or emission of energy in the form of particles or electromagnetic waves through a vacuum, material medium or space.

Earth’s atmosphere helps to regulate its temperature. However, the addition of gases such as carbon dioxide causes more energy to radiate back toward Earth. As a result, the atmospheric temperature increases over time. If Earth had no atmosphere, it would radiate nearly as much energy as it receives from the Sun. This implies that the temperatures on Earth would be lower than Earth’s current temperature.

The approximate size of the population of trout in the 1,000-acre lake would be 1460 trout.

The total area of the lake covered by the population is 1,000 acres. Three 50-acre area were sampled and the results were as follows:

Sample 1: 88 trouts per 50-acre

Sample 2: 80 trouts per 50-acre

Sample 3: 57 trouts per 50-acre

The average number of trouts per 50-acre of the lake can then be estimated as:

88+80+51/3 = 73 trouts per 50 acres

If the average number of trouts per 50-acre is 73, the population size of trout in the 1,000-acre can be estimated as follows:

50 acre = 73 trouts

1000 acre = 73 x 1000/50

                 = 1469 trouts.

In other words, the approximate population size of the trout in the lake is 1460 trout.
