The correct answer is: 1. meiosis.
In animal and plant cells, unique genetic combinations are created by chromosome recombination during the process of meiosis. Meiosis is a special type of cell division that produces gametes (sperm and eggs) with half the number of chromosomes. During this process, genetic material is exchanged between homologous chromosomes, leading to genetic diversity in the resulting gametes.

Advantage – Asexual Reproduction: Does not require the organism to find a mate, so it takes less energy and time to produce offspring.
Explanation: Asexual reproduction allows an organism to reproduce independently, which can be advantageous in stable environments where finding a mate may not be feasible.
Advantage – Sexual Reproduction: Allows for more genetic variation which increases the ability to survive and adapt.
Explanation: Sexual reproduction combines genetic material from two parents, leading to offspring with diverse traits that may enhance survival in changing environments.
Disadvantage – Asexual Reproduction: Allows for little to no genetic variation, which decreases its ability to survive and adapt.
Explanation: The lack of genetic diversity in asexual reproduction can make populations more vulnerable to diseases and environmental changes.
Disadvantage – Sexual Reproduction: Requires more time and energy to produce offspring.
Explanation: Sexual reproduction often involves finding a mate and engaging in courtship behaviors, which can be time-consuming and energetically costly.

To find out how long each member of the committee will spend making flowers, we will follow these steps:
1. Calculate the total time to make 525 flowers.
Each flower takes about 4.5 minutes (or 4 1/2 minutes).
Total time = Number of flowers × Time per flower
Total time = 525 flowers × 4.5 minutes/flower = 2362.5 minutes.
2. Convert the total time from minutes to hours.
There are 60 minutes in an hour, so:
Total time in hours = 2362.5 minutes ÷ 60 minutes/hour ≈ 39.375 hours.
3. Distribute the total time among the 6 committee members.
Time per member = Total time in hours ÷ Number of members
Time per member = 39.375 hours ÷ 6 members ≈ 6.56 hours.
So, each committee member will need to spend approximately 6.56 hours, which is about 6 hours and 34 minutes making flowers.
The closest answer to your options would be:
“525 flowers, 4 1/2 minutes ≈ 7 hours per person.”

To find the total height of the hotel, we need to multiply the number of levels by the height of each level.
1. We have 5x² – 2 levels.
2. The height of each level is 2x² + 1 inches.
So, the total height ( H ) can be calculated as follows:
[ H = (text{number of levels}) times (text{height of each level}) ]
[ H = (5x² – 2)(2x² + 1) ]
Now, we can use the distributive property to expand this:
[ H = 5x² cdot 2x² + 5x² cdot 1 – 2 cdot 2x² – 2 cdot 1 ]
So, calculating each term gives us:
– ( 5x² cdot 2x² = 10x^4 )
– ( 5x² cdot 1 = 5x² )
– ( -2 cdot 2x² = -4x² )
– ( -2 cdot 1 = -2 )
Now, combine the like terms:
[ H = 10x^4 + 5x² – 4x² – 2 ]
That simplifies to:
[ H = 10x^4 + (5x² – 4

To find the sum of the two missing terms in the equation ((m + 3)(m – 1) = m² + ____ + ____ – 3), we’ll first expand the left side:
[
(m + 3)(m – 1) = m(m) + m(-1) + 3(m) + 3(-1) = m^2 – m + 3m – 3 = m^2 + 2m – 3
]
Now, we can match this with the right side of the equation:
[
m^2 + ____ + ____ – 3
]
By comparing, we see:
– The term that corresponds to (m^2) is already present.
– The two missing terms in the right expression need to correspond with the (+2m) on the left.
Thus, (2m) can be written as:
[
2m = m + m

So the two missing terms are both (m). Now, we add them together:
[
m + m = 2m
]
Therefore, the sum of the two missing terms is (2m). So, the correct answer is:

To determine which polynomial is NOT equivalent to ( (5x – 2)(-2x + 4) ), we first need to expand this expression.
1. Use the distributive property (FOIL method):
[
(5x)(-2x) + (5x)(4) + (-2)(-2x) + (-2)(4)
]
This simplifies to:
[
-10x^2 + 20x + 4x – 8
]
Combine like terms:
[
-10x^2 + 24x – 8
]
Now, let’s compare this result with the provided options:
1. (-10x + 20x + 4x – 8 = 14x – 8) (not equivalent)
2. (-8 + 24x – 10x^2) (equivalent)
3. (4x + 20x – 10x^2 – 8 = -10x^2 + 24x – 8) (equivalent)
4. (-10x^2 + 24x – 8) (equivalent)
The polynomial that is NOT equivalent to ( (5x – 2)(-2x + 4) ) is:
-10x + 20x + 4x – 8.

For the list of facts, it does not make sense to add the cost of a pass, the area, and the employees because these quantities cannot be expressed using the same unit. The number 168 has meaning for the list.
Explanation: When considering a list of different types of data (cost, area, number of employees), you cannot simply add them together because they are measured in different units (e.g., money, square units, counts). However, if 168 pertains to a particular quantity (like the number of employees), then it holds meaning within that specific context. Make sure each value you add is in the same measurement category for meaningful aggregation!
See lessA state department of public safety added 1/3 x² + 5x miles of highway to connect CoolTown and Bragville. It cost the department 3x² – 9 thousand dollars to complete each mile of interstate. Which expression shows the total cost, in thousands of dollars, of creating this highway?
To find the total cost of creating the highway, we will multiply the length of the highway (in miles) by the cost per mile. 1. The length of the highway is given by the expression:(frac{1}{3}x^2 + 5x) miles. 2. The cost per mile is given by:(3x^2 - 9) thousand dollars.Now, we need to multiply theseRead more
To find the total cost of creating the highway, we will multiply the length of the highway (in miles) by the cost per mile.
1. The length of the highway is given by the expression:
(frac{1}{3}x^2 + 5x) miles.
2. The cost per mile is given by:
(3x^2 – 9) thousand dollars.
Now, we need to multiply these two expressions together to find the total cost:
[
text{Total Cost} = left(frac{1}{3}x^2 + 5xright) times (3x^2 – 9)
]
Let’s distribute:
1. (frac{1}{3}x^2 times 3x^2 = x^4)
2. (frac{1}{3}x^2 times (-9) = -3x^2)
3. (5x times 3x^2 = 15x^3)
4. (5x times (-9) = -45x)
Now combine these results:
[
x^4 + 15x^3 – 3x^2 – 45x
]
However, the question asks for an expression in thousands, so we can adjust the combined expression to show only the required terms related to the cost without focusing heavily on linear terms related
See lessJames knows that when he walks, he takes about 120 steps per minute and that each step is 2.75 feet long. Which calculations is most reasonable for James to use to find out his walking speed in miles per hour? 120 steps 1 minute 2.75 feet 5,280 feet 1 mile 60 minutes 120 steps 1 minute 2.75 feet 1 step 5,280 feet 1 mile 60 minutes 120 steps 2.75 feet 1 mile 60 minutes 1 minute 5,280 feet 1 hour 120 steps 1 minute 2.75 feet 1 step 5,280 feet 1 mile 60 minutes
To find James's walking speed in miles per hour, we need to calculate how far he travels in one hour.

To find James’s walking speed in miles per hour, we need to calculate how far he travels in one hour. The first step is to calculate the distance he covers in one minute and then convert that to miles per hour.
1. Steps per minute: 120 steps
2. Distance per step: 2.75 feet
First, calculate the distance covered in one minute:
– Distance in one minute = 120 steps × 2.75 feet/step = 330 feet.
Next, calculate the distance covered in one hour (60 minutes):
– Distance in one hour = 330 feet/minute × 60 minutes = 19,800 feet.
Now, convert feet to miles:
– Since 1 mile = 5,280 feet, we can find miles by dividing the total feet by the number of feet in a mile:
– 19,800 feet ÷ 5,280 feet/mile = 3.75 miles.
Since we’re looking for the most reasonable calculation, the correct choice is:
120 steps . 1 minute . 2.75 feet . 5,280 feet . 1 mile . 60 minutes.
This calculation clearly lays out the relationship between steps, distance per step, time in minutes and hours, and the conversion to miles.

To accurately compare the populations of Utah and Wyoming, we need to refer to their estimated population statistics.
As of recent estimates, the population of Utah is approximately 3.3 million, while the population of Wyoming is around 580,000.
To compare:
– The population of Utah (3.3 million) is roughly 5.7 times the population of Wyoming (580,000).
– Conversely, the population of Wyoming is about 0.18 times the population of Utah.
Based on the options provided:
– O The population of Wyoming is about 2 times the population of Utah. (Incorrect)
– O The population of Utah is about 5 times the population of Wyoming. (Closest, but not exact)
– O The population of Wyoming is about 20 times the population of Utah. (Incorrect)
– O The population of Utah is about 0.5 times the population of Wyoming. (Incorrect)
Therefore, while “The population of Utah is about 5 times the population of Wyoming” is not exact, it is the closest option available. However, both states have populations that do not fit neatly into those comparisons due to their actual counts.

Explanation:
To find the relative size of the larger cell to the smaller cell, you need to divide the coefficients (4 by 8) to get 0.5. Then, when you divide the powers of ten (10⁻⁶ by 10⁻⁵), you subtract the exponents, resulting in 10⁻¹. Finally, multiplying these results (0.5 × 10⁻¹) gives you 0.05, indicating that the larger cell is 0.05 times the size of the smaller cell.

The correct answer is: It can affect the price and availability of goods and services.
Explanation: The law of supply and demand describes how the price of a good or service is determined by the relationship between its availability (supply) and the desire for it (demand). When demand for a product increases and supply remains constant, prices tend to go up, making the product less affordable or accessible to consumers. Conversely, if there is a surplus of a product and demand decreases, prices may drop, making the product more affordable. This interplay affects consumers directly in terms of what they pay and whether they can find the goods and services they want.
