Write a letter to your friend telling him about two reasons he should come to your school
Answer:
Dear, Friend
I am writing to you because I feel that you should really consider coming to my school. When I come to school I think of the new things I may learn and the new challenges I will face. Like most people these new expiriences and challenges may be nerve racking to face, but that's why I want you to join my school . Our school may not be the greatest in the world but the people and staff who make up this school are what make it really special. The enviroment that has been manifested by each and every individual in this school is quite spectacular. It is something so significant yet overlooked. I feel safe to share my opinions and open up to my fellow students and teachers. Another reason to joing my school is the facilites. The facilitiy itself is very appealing and is well kept. A wise man once told me that a clean work enviroment is a productive one. If you come to this school you will feel safe, accepted, and you will be more productive than ever. So if you or anyone is ever on the fence about joining this school just join us. Attending this school will be one of the best decisions you will ever make.

What causes waves to occur in the ocean?
Answer:
Wind
Explanation:
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

The best explanation for the net movement of molecules is that Water is moving at equal rates both and out of the cell. So, the correct option is (C).
What are Different types of Solutions?
There are 3 types of solution. These are:
1. Hypertonic Solution
Hypertonic solutions are those in which the solute concentration is higher than in any other solution. For example, the internal solution of a cell in it.
If these cells are placed in a hypertonic solution, the movement of water outside the cell is greater than inside the cell.
2. Hypotonic Solution
Hypotonic solutions are those in which the concentration of the solute is less than that of the other solution.
If a cell is placed in a hypotonic solution, the movement of water inside the cell is greater than the movement outside the cell.
3. Isotonic Solution
Isotonic solutions are a type of solution whose strength is equal to that of another solution.
If a cell is placed in an isotonic solution, there is an equal rate of movement of water into and out of the cell.
For the above information, isotonic solution is used in the experiment because the movement of water in and out of the cell is the same.
Thus, the best explanation for the net movement of molecules is that Water is moving at equal rates both and out of the cell. So, the correct option is (C).

Which of the following was the major contribution made by Avery, MacLeod, and McCarty that strengthened the argument that the transforming agent in Griffith's experiment was DNA? Multiple Choice Transformation of nonvirulent cells with a DNA extract was successful when DNase was added. Transformation of nonvirulent cells with a DNA extract was blocked only if protease was added. Transformation of nonvirulent cells with a DNA extract was blocked only if RNase was added. Transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added.
The major contribution made by Avery, MacLeod, and McCarty was 'transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added'. This observation supported the idea that the transforming agent in Griffith's experiment was DNA.
The Avery–MacLeod–McCarty experiment showed that DNA was the transforming agent observed in Griffith's experiment.
Griffith's experiment (1928) suggested that bacteria were capable of transferring genetic information (DNA) by a process of horizontal gene transfer called transformation.
While the bacteria were killed by heat, Frederick Griffith observed that the DNA had was taken up by II-R strain bacteria via transformation.
Avery–MacLeod–McCarty experiment observed that protease enzymes did not destroy the transforming agent (but DNAse destroyed this transforming principle), thereby suggesting that the transforming agent in Griffith's experiment was bacterial DNA.

2. What new realizations do you have about solving problems involving sequence? How would you connect this to real life? How would you use this in making decisions?
Answer:
To solve real life problems involving sequences,we use the word 'SEE PLAAN DO AND LOOK BACK, when we have problems, we need to see what is the problem about and what is the cause. Then we plan how we would solve that problem. Next is to do what we have planned. The last thing is to look back to see if we have made errors in the solution and it will familiarize us with method of sulotion and this may be useful for solving a future problem.

A comet has an orbit size of 3.5 AU & its orbit time is 6.54 years. T² = 42.875 years. What does R³ equal?
Answer:
42.875 AU is the answer.
Explanation:
Kepler's third law allows us to find the answer for the orbital radius of the comet's orbit and the relationship of the magnitudes are:
Orbital radio is a = 3.49 AU The ratio of the orbit to the cube to the period squared gives the Kepler constant.
Kepler studied the motion of bodies in the solar system creating mathematical relationships that describe their motion, Kepler's third law which is a direct application of Newton's second law to the orbit of the planets around the sun is
T² = K a³
Where T is the period of the orbit, a is the semi-major axis of the ellipse and K is a constant called Kepler's constant given by
K = [tex]\frac{4 \pi ^2 }{GM_s}[/tex] = 3 10⁻¹⁹ s²/m³
Where G is the constant of gravitation universes, M_s the mass of the Sun
In this case they indicate the size of the orbit tabulated a = 3.5 AU and the period T = 6.54 years, let's reduce the two magnitudes to the international system of measurements (SI)
T = 6.54 years [tex]( \frac{365 d}{1yr} ) ( \frac{24h}{1 d} ) ( \frac{3600s}{1 h} )[/tex] = 2.062 10⁸ s
Let's calculate the radius of the orbit
a = [tex]\sqrt[3]{\frac{ T^2 }{K} }[/tex]
a = [tex]\sqrt[3]{\frac{(2.062 \ 10^8 )^2 }{3 \ 10^{-19}} }[/tex]
a = [tex]\sqrt[3]{0.1417 \ 10^{36}}[/tex]
a = 0.5214 10¹² m
Let's reduce to astronomical units, which corresponds to the distance from the Sun to the earth
a = 0.5214 10¹² m ( [tex]\frac{1AU}{1.496 \ 10^{11}}[/tex] )
a = 3.49 AU
Let's observe that it is practically equal to the tabulated value.
The ratio of the orbit to the cube to the period squared gives the Kepler constant, which is practically invariant for all bodies in the solar system.
In conclusion using Kepler's third law we can find the radius of the comet's orbit and the relationship of the magnitudes are:
Orbital radio is a = 3.49 AU The ratio of the orbit to the cube to the period squared gives the Kepler constant

Is the tamarisk beetle an invasive species? Read the following passage, and use the evidence provided to determine whether or not they would be classified as invasive.
“Tamarisk trees were introduced to the U.S. as an ornamental shrub due to their pretty pink color and ability to provide erosion control. However, they were soon recognized as invasives due to their hoarding of light, water, and nutrients, drying out riparian areas. They also were outcompeting the plants that the Southwestern willow flycatcher nested in. As a result, the tamarisk beetle was introduced because they eat the tamarisk plant. They were extremely effective, except there was one caveat- the flycatcher birds had begun to use the tamarisk to nest in. So, protocols had to be adjusted to allow some tamarisk to remain; no beetles were released within 200 miles of any flycatcher nest, so the bird populations could continue to grow while the beetles continued to remove invasive tamarisk trees in other areas.”
(1 point)
Yes, the tamarisk beetle is invasive, because it is destroying Southwestern willow flycatcher habitat.
Yes, the tamarisk beetle is invasive, as it is not native to the United States.
No, the tamarisk beetle is not invasive, because it is only destroying the intended invasive plants.
No, the tamarisk beetle is not invasive, as they were purposefully introduced
