As a result of the seed growing in a field with a different population of plants, we can witness how gene flow works in action.
It will have introduced its alleles into that population once this plant reproduces there. Any movement of people from one group to another—also known as migration—and/or the genetic material they carry is referred to as gene flow. Pollen being carried to a new location by the wind or individuals relocating to new cities or nations are just a few examples of the many different types of events that contribute to gene flow.
Vertical and horizontal gene flow are two different types of gene transfer. Gene flow describes the transfer of genetic material between groups.

Answer: d. Y=2
Step-by-step explanation:
The diagram shows two squares constructed on the sides of a rectangle. What is the area of square A?
The area of the square A is 19.98 square feet
Calculating the area of square A?From the question, we have the following parameters that can be used in our computation:
Two squares constructed on the sides of a rectangle.
Let the side lengths of square C be x
Let the side lengths of rectangle B be x and y
So, we have
x² = 5
xy = 10
Solving for x and y, we have
x = 2.24 and y = 4.47
The area of square A is
Area = y²
So, we have
Area = 4.47²
Evaluate
Area = 19.98
Hence, the area of the square A is 19.98 square feet

Solving a system of equations we can see that:
She needs to use 56 oz of the 85% solution.She needs to use 14 oz of the 60% solution.How many ounces of each solution should she use?We can use the variables:
x = mass of the 60% solution.
y = mass of the 85% solution.
We can write a system of equations.
x + y = 70
x*0.6 + y*0.85 = 70*0.8
We can isolate x on the first equation to get:
x = 70 - y
Replace that in the other one:
(70 - y)*0.6 + y*0.85 = 70*0.8

They are similar because AB is four more than ED, AC is three more than DF, and BC is three more than EF.
To determine if two triangles are similar, we need to compare the ratios of the corresponding sides.
In this case, the given information allows us to compare the lengths of the corresponding sides of triangle ABC and triangle DEF.
We have:
AB = 16 and ED = 12 (AB is four more than ED)
AC = 12 and DF = 9 (AC is three more than DF)
BC = 1 and EF = 9 (BC is three more than EF)
The corresponding sides are proportional because the ratios of the lengths are consistent:
AB/ED = 16/12 = 4/3
AC/DF = 12/9 = 4/3
BC/EF = 1/9
Since the ratios of the corresponding sides are the same, we can conclude that triangle ABC and triangle DEF are similar

What is the equation of the parabola shown in the graph?
The equation for the parabola in the graph is the one in option C:
y = (-1/4)x² -2x - 7
Which is the equation of the parabola?Remember that a parabola with leading coefficient a and a vertex (h, k) can be written as:
y = a*(x - h)² + k
Here the vertx is at (-4, -3), then:
y = a*(x + 4)² - 3
And we can see that it passes through the point (0, -7), replacing that we will get:
-7 = a*(0 + 4)² - 3
-7 = a*16 - 3
-7 + 3 = a*16
-4 = a*16
-4/16 = a
-1/4 = a
The quadratic is:
y = (-1/4)*(x + 4)² - 3

help? A crayon is shaped like a triangular prism. The base of the crayon is shown. If the crayon is 90 millimeters long, how many cubic millimeters of wax is used to make a box of 8 crayons?
Answer:
Unknown but formula (Check step by step solution)
Step-by-step explanation:
Without the image of the base of the crayon, I cannot determine the exact dimensions of the triangular prism or calculate the volume of a single crayon. However, I can give you a general formula for calculating the volume of a triangular prism and use it to find the total volume of wax needed to make a box of 8 crayons.
The formula for the volume of a triangular prism is:
Volume = (1/2) x base x height x length
where base is the area of the base of the triangular prism, height is the height of the triangular prism, and length is the length of the triangular prism.
Assuming all the crayons in the box have the same dimensions, let's say the base of the triangular prism has a length of L and a width of W. We can calculate the area of the base of one crayon as:
Base area = (1/2) x L x W
Since the crayon is 90 millimeters long, its height is 90 millimeters. Therefore, the volume of one crayon is:
Volume of one crayon = (1/2) x L x W x 90
To find the total volume of wax used to make a box of 8 crayons, we can multiply the volume of one crayon by the number of crayons:
Total volume of wax = Volume of one crayon x 8
Total volume of wax = (1/2) x L x W x 90 x 8
Total volume of wax = 360 x L x W
Again, without knowing the exact dimensions of the triangular prism, I cannot calculate the total volume of wax used to make a box of 8 crayons. But you can use the formula above and substitute the values of L and W based on the dimensions of the base of the crayon to find the answer.

Answer:
(-5, -5)
Step-by-step explanation:
Given system of linear inequalities:
[tex]\begin{cases}y < \dfrac{1}{2}x+5\\\\y\leq-3x-2\end{case}[/tex]
When graphing inequalities:
< or > : dashed line.≤ or ≥ : solid line.< or ≤ : shade under the line.> or ≥ : shade above the line.To graph linear inequalities, treat them as equations (swap the inequality sign for an "equals" sign). Plug in two values of x to find two points on the line to help draw the lines.
Graphing the line y < (1/2)x + 5Substitute x = 0 and x = 6 into the equation of the inequality to find two points on the line.
[tex]\begin{aligned}x=0 \implies y&=\dfrac{1}{2}(0)+5\\y&=5\end{aligned}[/tex] [tex]\begin{aligned}x=6 \implies y&=\dfrac{1}{2}(6)+5\\y&=8\end{aligned}[/tex]
Plots points (0, 5) and (6, 8).
As the inequality sign is <, draw a dashed line through the plotted points and shade below the line.
Graphing the line y ≤ -3x - 2Substitute x = 0 and x = 2 into the equation of the inequality to find two points on the line.
[tex]\begin{aligned}x=0 \implies y&=-3(0)-2\\y&=-2\end{aligned}[/tex] [tex]\begin{aligned}x=2 \implies y&=-3(2)-2\\y&=-8\end{aligned}[/tex]
Plots points (0, -2) and (2, -8).
As the inequality sign is ≤, draw a solid line through the plotted points and shade below the line.
SolutionThe solution set is the set of points contained within the overlapping shaded region and on the solid line.
Therefore, a point in the solution set is (-5, -5).

A $6.83
B $65.00

D $1,365.00
Michelle pays $1365 in total.
Option D is the correct answer.
We have,
To calculate the total amount Michelle pays for the T-shirts, we need to consider the cost per shirt and the shipping fee.
The cost per shirt is $6.50, and she ordered 200 shirts, so the cost of the shirts alone is:
= $6.50 x 200
= $1300
The shipping fee is 5% of the total order, which is:
= 5% x $1300
= $65
To find the total amount Michelle pays, we add the cost of the shirts and the shipping fee:
= $1300 + $65 = $1365
Therefore,
Michelle pays $1365 in total.

The family then travelled 38km from Camp Carol and reached Phoenix in 27minutes. Determine the average speed they travelling at?
The family traveled from Camp Carol to Phoenix at an average speed of approximately 84.44 kilometers per hour.
How to calculate average speed?Speed is simply referred to as distance traveled per unit time.
It is expressed mathematically as:
Speed = Distance / time
Given that the family traveled 38 km from Camp Carol to Phoenix in 27 minutes:
Distance traveled = 38 kilometers
Time taken = 27 minutes
First, convert the time from minutes to hours:
Time taken = ( 27 / 60 ) hours
Time taken = 0.45 hour
We can now calculate the average speed using the above formula as follows:
Average speed = Distance / time
Average speed = 38 km / 0.45 h
Average speed = 84.44 km/h
Therefore, the average speed is approximately 84.44 km/h.
