The statements that accurately describe the recombinant plasmid are:
1. This molecule was made using EcoRI and ligase.
2. This is a DNA molecule that contains foreign DNA.
3. It can be taken into a bacterial cell and used to produce foreign proteins.
Explanation:
– EcoRI is a restriction enzyme that cuts DNA at specific sites, allowing foreign DNA to be inserted into plasmids. Ligase is used to join the DNA fragments together.
– A recombinant plasmid is indeed a DNA molecule that contains foreign DNA.
– Once inside a bacterial cell, the plasmid can be replicated and translated to produce foreign proteins.
The other statements, “This is a transformed bacteria” and “This is a recombinant endonuclease,” are not accurate. The first describes the bacterial cell that has taken up the plasmid, rather than the plasmid itself, and the second confuses the concept of plasmids with the enzymes that cut DNA.

The statements that accurately evaluate the DNA technology presented are:
1. Gel electrophoresis is used to compare DNA fragment lengths to determine relatedness between two individuals.
– This statement is correct. Gel electrophoresis allows for the separation of DNA fragments based on size, which can help analyze genetic similarities and differences.
2. Recombinant plasmids are used to produce transformed bacteria that can produce large amounts of human protein.
– This statement is also correct. Recombinant plasmids can carry human genes into bacteria, enabling the bacteria to produce human proteins in large quantities.
3. Polymerase Chain Reaction (PCR) is used to produce large amounts of DNA for gel electrophoresis.
– This statement is correct as well. PCR amplifies specific DNA sequences, making it possible to produce enough DNA for analysis through gel electrophoresis.
The other statements are inaccurate:
– PCR is used to produce large amounts of protein. (Incorrect, as PCR amplifies DNA, not proteins.)
– Recombinant plasmids are used to produce large amounts of DNA. (Incorrect, recombinant plasmids are primarily designed for producing proteins, not large amounts of DNA.)

The correct answer is D. (x + 4)² + (y + 5)² = 6.
To find the equation of a circle with a given center and radius, we use the standard form of the equation:
[
(x – h)² + (y – k)² = r²
]
where ((h, k)) is the center of the circle and (r) is the radius.
In this case, the center is ((-4, -5)) and the radius is (sqrt{6}).
1. Substitute (h = -4) and (k = -5):
[
(x + 4)² + (y + 5)²
]
2. Next, square the radius (sqrt{6}):
[
(sqrt{6})² = 6
]
3. Combine the results:
[
(x + 4)² + (y + 5)² = 6
]
Thus, the equation of the circle is ((x + 4)² + (y + 5)² = 6), which matches option D.

To predict how many times the spinner will land on yellow after spinning it 72 times, we first need to know the probability of landing on yellow. If the spinner has 4 equal sections (for example, red, blue, yellow, and green), then the probability of landing on yellow is 1/4.
Now, you would calculate the expected number of times it lands on yellow by multiplying the total spins by the probability:
Expected times on yellow = Total spins × Probability of yellow
If the probability of landing on yellow is 1/4, then:
Expected times on yellow = 72 spins × (1/4) = 18 times
So the best prediction for the number of times it will land on yellow is 18 times.

To find the distance you will drive on Street B from the movie store to your friend's house, we can break down the distances based on the information provided. 1. You drive from your house to the movie store on Street A, which is 1 mile.2. From the movie store, you will drive to your friend's houseRead more
To find the distance you will drive on Street B from the movie store to your friend’s house, we can break down the distances based on the information provided.
1. You drive from your house to the movie store on Street A, which is 1 mile.
2. From the movie store, you will drive to your friend’s house on Street C, which is given as 3 miles.
To find out the distance you will drive on Street B, you can assume that Street B is the direct route from the movie store to your friend’s house, which we need to find.
Using the Pythagorean theorem, since the scenario involves a right triangle (with distances representing the legs of the triangle), we can calculate it as follows:
– Let ( a = 1 ) mile (to the movie store),
– Let ( c = 3 ) miles (to your friend’s house via Street C).
We need to find ( b ):
[
b^2 = c^2 – a^2
]
Substituting the values:
[
b^2 = 3^2 – 1^2
]
[
b^2 = 9 – 1
]
[
b^2 = 8
]
[
b = sqrt{8} approx 2.83 text{ miles}

To determine the correct equation that relates the number of cones sold (x) to the profit (y), we need to analyze how profit changes with the number of cones sold.
Typically, profit can be expressed in a linear form, where the profit increases with each cone sold. If the table shows a consistent increase in profit as the number of cones sold increases, we can identify the coefficients in a potential equation.
Since we don’t have the specific data from the table, I’ll guide you through the logical approach:
1. Identify a pattern in profit increase related to the number of cones sold.
2. Look for the slope (rate of profit per cone) and y-intercept (profit when no cones are sold).
3. The equation of the line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
From the options given:
– If profit increases consistently, “y = 2x” (meaning $2 profit per cone) might be a candidate if that reflects the data.
– If there’s some fixed cost or starting profit, the y-intercept would change accordingly.
Based on common scenarios, “y = 2x” may likely express a profit of $2 for each cone sold without additional fixed costs.
Check your table to confirm this pattern, and let me know if you need further help analyzing it!

The statement that is NOT true is: The product of the slopes of line c and line b is -1.
Explanation: Since lines a and b are parallel, they have the same slope, let’s call it ( m ). Line c is perpendicular to both lines a and b, which means its slope, let’s call it ( m_c ), is the negative reciprocal of ( m ). Therefore, the product of the slopes of lines b and c is:
[
m cdot m_c = m cdot left(-frac{1}{m}right) = -1
]
However, since line c is perpendicular to both lines a and b, the statement about lines b and c needs to reflect that one of these will retain a product of -1, but the given statement incorrectly implies a relationship that doesn’t exist in the context of both lines. The correct statement should reflect that ( m_b cdot m_c = -1 ) holds true.
