Answers
Answer:
A. heredity, environment, and culture
Wellness is a daily struggle that is influenced by heredity, environment, and culture.
What is Heredity?The genetic heritage that our biological parents have left behind is referred to as heredity. That's why we resemble them. In more detail, it refers to the passing down of traits from one generation to the following.
These characteristics can be behavioral or physical, such as eye color, blood type, or an illness. For instance, honeybees' hygienic behavior, which motivates them to remove unhealthy larvae from the nest, is a hereditary trait.
Genes, which can contain several alleles, are responsible for determining hereditary features.
Therefore, Wellness is a daily struggle that is influenced by heredity, environment, and culture.

A. Turn the raw sewage into pure water,
B. Remove the organic materials from the sewage,
C. Transfer the raw sewage to a larger body of water,
D. Dilute the raw sewage with water,
Answers
Answer:
The correct option is;
B. Remove the organic materials from the sewage
Explanation:
In water treatment plants, floating the and settling solid wastes (by gravity) materials are removed and further process of sedimentation, screening grit removal are performed, to segregate and remove form solid wastes. Sedimentation tanks known as primary clarifiers are used to remove suspended solid wastes.
The soluble organic materials that pass through primary treatment are removed in the secondary treatment
The reduction and removal of the soluble and insoluble organic matter serves to preserve the amount of oxygen available in the final destination of the treated sewage waste water including a lake or stream.

The Frackile Power Plant combusts methane to produce electricity. The plant burn 37,500,000 cubic yards of methane each year. The plant produces 61,626,000 kWh of electricity. Calculate the effciency of this power plant.
Answers
The energy contained in the 37,500,000 yd³ of methane and the energy
produced of 61,626,000 kWh, give an efficiency of approximately 19.5%
How can the efficiency of a power plant be found?The given parameters are;
The volume of methane combusted by the Frackile Power Plant = 37,500,000 yd³
The energy produced by the plant = 61,626,000 kWh
Required:
The efficiency of the power plant.
Solution:
The calorific vale of methane = 55.4 MJ/kg
37,500,000 yd³ = 28,670,807,174 L
The number of standard volumes are therefore;
\(\dfrac{28,670,807,174 \, L}{22.414 \, L} \approx \mathbf{1279147281.79}\)
Mass of the methane = 16.04 g × 1279147281.79 ≈ 2.05175224 × 10⁷ kg
Energy produced = 2.05175224 × 10⁷ kg × 55.4 MJ/kg = 1,136,670,740.96 MJ
1 kWh = 3,600 kJ
61,626,000 kWh = 61,626,000 × 3,600 kJ = 221,853,600 MJ
\(Efficiency = \mathbf{\dfrac{Energy \ put \ out }{Energy \ value \ put \ in}}\)
The efficiency is therefore;
\(Efficiency = \dfrac{221853600}{1136670740.96 } \times 100 \approx \mathbf{19.5\%}\)
The efficiency of the power plant is approximately 19.5%

Answers
Answer:
To find out how long it will take for the balance in the account to reach $10,000, you can use the following formula:
n = log(10000 / 4000) / log(1 + (0.09 / 12))
This formula calculates the number of periods (in this case, months) required for the balance to grow from $4,000 to $10,000 at a 9% annual interest rate compounded monthly.
Plugging in the values, we get:
n = log(10000 / 4000) / log(1 + (0.09 / 12))
= log(2.5) / log(1.0075)
= 0.964 / 0.0075
= 128.53
So it would take approximately 128 months, or just over 10 years, for the balance in the account to reach $10,000.
Note: This is just an approximation and the actual time required may vary slightly due to the way that the interest is compounded.

Two cells have the same volume but significantly different surface area values due to differences in their shapes. The cell with the greater surface area is likely to
a:take in nutrients more rapidly than the other cell
Scientists have two samples of cells from the same patient. They find the endoplasmic reticulum of the liver cells have more folds than the endoplasmic reticulum of the skin cells. Which of the following is the best explanation?
a:The greater number of folds allows for greater surface area for synthesizing lipids.
As a cell grows, its demand for nutrients increases. Which of the following best describes how the cell's ability to absorb nutrients through diffusion changes as it grows?
this answer is wrong: It increases because the cell now has more volume to store acquired nutrients.
The following table presents data on the extent of diffusion of iodine into cubes of potato over a period of five minutes:
Cube Volume (cm3) Percent of Total Cube Volume That Absorbed Iodine
0.25 75.2%
1 51.3%
4 21.2%
The potato cubes act as a representation of cells of different sizes. The iodine represents diffusion of nutrients into the cell. What does the data indicate about the relationship between cell volume and nutrient absorption?
a: The smallest cell was most successful at nutrient uptake.
Two cells are measured under a microscope, and their dimensions are used to calculate their surface area and volume. The cells are examined again after a period of growth, and their measurements are recorded in the table below.

your welcome :)
Answers
Cells are so small that you need a microscope to examine them. Why?
To answer this question we have to understand that, in order to survive, cells must constantly interact with their surrounding environment.
Gases and food molecules dissolved in water must be absorbed and waste products must be eliminated. For most cells, this passage of all materials in and out of the cell must occur through the plasma membrane (see diagram above).
Each internal region of the cell has to be served by part of the cell surface. As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
Finally, at some point, there is just enough surface available to service all the interior; if it is to survive, the cell must stop growing.
Surface Area to
Volume Ration The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.

A company issued 6,000 shares of stock at $10 each, with a par value of $2 what amount is credited as common stock
Answers
The answer provided below has been developed in a clear step by step manner. Step: 1
Number of shares issued = 6,000
Issue price per share = $10 Par value per share = $2
Debit to cash = Number of shares issued x Issue price per share
= 6,000 x $10 = $60,000
Credit to common stock = Number of shares issued x Par value
per share 6,000 x $2
= $12,000
Credit to paid in capital in excess of par = Number of shares issued x (Issue price per share - Par value per share)
= 6,000 × ($10-$2) = 6,000 x $8
= $48,000
The amount is credited as paid in capital in excess of par = $48,000

Answers
To calculate the percent change in the total wind power capacity in the United States from 2000 to 2015, we can use the following formula:
Percent Change = (Final Value - Initial Value) / Initial Value * 100
Given:
Initial Value (2000) = 2540 MW
Final Value (2015) = 72,500 MW
Applying the formula:
Percent Change = (72,500 - 2540) / 2540 * 100
= 69,960 / 2540 * 100
≈ 2757.48%
Therefore, the percent change in the total wind power capacity in the United States from 2000 to 2015 is approximately 2757.48%.

A large company is being sued for false advertisement because 18% of the flashlights in its shipping boxes are defective, but the company claims that only 8% are defective. You plan to use hypothesis testing to determine whether there is significant evidence that the company is falsely advertising.
Part A: State the null and alternate hypotheses for the significance test. (2 points)
Part B: In the context of the problem, what would a Type I error be? A Type II error? (2 points)
Part C: If the hypothesis is tested at a 10% level of significance instead of 5%, how will this affect the power of the test? (3 points)
Part D: If the hypothesis is tested based on the sampling of 100 boxes of flashlights rather than 1,000 boxes of flashlights, how will this affect the power of the test? (3 points)
Answers
1. Null hypothesis: The proportion of defective flashlights in the company's shipping boxes is 8%.
Alternative hypothesis: The proportion of defective flashlights in the company's shipping boxes is greater than 8% (i.e., the company is falsely advertising).
2. A Type I error in this context would be to reject the null hypothesis (i.e., conclude that the company is falsely advertising) when the null hypothesis is actually true (i.e., the proportion of defective flashlights is indeed 8%).
A Type II error would be to fail to reject the null hypothesis (i.e., conclude that the company is not falsely advertising) when the alternative hypothesis is actually true (i.e., the proportion of defective flashlights is greater than 8%).
3. Increasing the significance level from 5% to 10% would increase the probability of rejecting the null hypothesis when it is actually true
4. If the hypothesis is tested based on the sampling of 100 boxes of flashlights rather than 1,000 boxes of flashlights, the power of the test is likely to be lower
How to explain the hypothesisThe power of a statistical test is the probability of rejecting the null hypothesis when the alternative hypothesis is true. Generally, the power of a test increases with sample size. Therefore, if the hypothesis is tested based on the sampling of 100 boxes of flashlights rather than 1,000 boxes of flashlights, the power of the test is likely to be lower.
With a smaller sample size, the estimate of the population parameter is less precise, and the variability in the data is higher. This reduces the power of the test to detect a true difference between the null and alternative hypotheses. In addition, the smaller sample size may limit the ability to detect small effects, which may lead to a higher probability of a type II error (failing to reject the null hypothesis when it is false).

Assume a country's banking system has limited reserves. Suppose that the central bank buys $400 billion worth of
government securities from the public. If the required reserve ratio is 20 percent, the maximum increase in the
money supply is
(A) $1,600 billion
(B) $1,800 billion
(C) $2,000 billion
(D) $2,200 billion
(E) $2,400 billion
Answers
Answer:
(C) $2,000 billion.
Explanation:
The maximum increase in the money supply is determined by the money multiplier formula, which is:
money multiplier = 1 / reserve requirement
In this case, the reserve requirement is 20%, or 0.2, so the money multiplier is:
money multiplier = 1 / 0.2
= 5
This means that for every dollar of reserves, the banking system can create up to $5 of new money. Since the central bank bought $400 billion worth of government securities, this means that the banking system now has an additional $400 billion in reserves that it can use to create new money. Therefore, the maximum increase in the money supply is:
maximum increase in money supply = money multiplier x increase in reserves
= 5 x $400 billion
= $2,000 billion
Therefore, the answer is (C) $2,000 billion.
