What are mutations? Variation in population

Which of these is true of mutations?-introducing variation

FYI; A change in gene (DNA)=mutations. Mutations introduce variation in populations

There are beneficial mutations that help an organism (think about a white fur gene for a rabbit living in the arctic). There are also mutations that harm and can kill an organism (think about diseases like Sickle Cell Anemia). Remember, for evolution to work you need mutations. The white fur mutation for the rabbit helps it to survive in the snow of the Arctic because it is camouflaged.

RNA molecules are synthesized from DNA template

Note: The nucleus of a cell contains the cell’s DNA (with few exceptions-i.e. Blood cell) The DNA contains all of the instructions to make any protein needed to replace any cell in the body. So what takes place in the cell is the RNA reading & transcribing the directions of the type of protein needing to be made; it’s like going to the library and studying the information you need to know from a book. To do this the specific double helix shaped chromosome containing this information is unzipped by the RNA molecule so it can be copied

There is an answer choice that is similar: overpopulation of plankton, don’t get mixed up.

Also NoteEl Niño also reduces the upwelling of cold water off the coast of the Americas. When this happens, fish either die or migrate into areas where they'll find more to eat. With the fish gone, seabirds that depend on them many die or go elsewhere. Kelp forests are often destroyed by storms and ocean swell

No phytoplankton word in the answer- It disrupts the whole food chain- warm waters

Also Note phytoplankton = no fish bc they have no (phytoplankton) food to eat. No fish= no seagulls bc they have no fish to eat. Fisheries have no fish

Losses of phytoplankton-small fish starve

You jog 2/3 of 6 miles = 4 miles = 120x4 calories = 480

12,800 students

If it asks for percent it will be 64%

Steps:

1. Multiply 1 million x .02 (2% gifted students) = 20,000 gifted students

2. 20,000 gifted students x 0.8 (80% bachelor’s) = 16,000

3. 16,000 gifted students x 0.8 (80% masters) = 12,800

352

Steps:

1. Need to find number of students in 11th and 12th grade. If 56% are 9th or 10th, then 44% are 11th and 12th. 1200x0.44=528

2. Of the 528 remaining students, 1/3 are 11th grade therefore 2/3 are 12th. 528x2/3=352

3. Multiply by 50 to get how long 50 would be end to end. 50x15.5956=779.78cm

When adding fractions you need to make the denominators the same. In this case you can divide 4/8 by 2/2 to get 2/4.

3/4+2/4=5/4. Turn this into a mixed number and you get 1 1/4. The numerator is therefore 1.

Another version of this is 3/4+2/5. (Make both fractions have 20 as the denominator. Giving 15/20+8/20=23/20=1 3/20. The numerator here would be 3.)

Another version is 3/4+4/5. (Again make both fractions have 20 as the denominator. Giving 15/20+16/20=31/20=1 11/20. The numerator here would be 11.)

This will be an upwards parabola. Find either x or y for each point. Put that into the equation to get the other point for each coordinate. For example to get where it crosses the x-axis, put in y=0.

x=+3 or -3

Another version has y=9-x² as the parabola. This is a downwards parabola, but just do the same thing.

The triangle goes from the center of each circle. This means that the radius of each circle is half the length of the triangles side. This is an equilateral triangle as all the angles are 60 degrees. All the sides are equal.

Perimeter of a triangle is side length x 3.

side length = 20.

Radius of the circle is half side length. 20/2=10

BUT - the question wants to know the perimeter of the circle that isn't the arc inside the triangle.

The length of that arc is angle of the arc/360 x circumference

=10.47

Our final answer is 62.83-10.47=52.36

52.4cm

an alternative way to find out the perimeter of the circle is to find the angle of the arc outside of the triangle (360-60=300)

Now do 300/360 x 62.83 = 52.4
