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).

What is cellular respiration?Cellular respiration is a biochemical process that disintegrate glucose to generate ATP, which can then be used as energy to power a variety of reactions all through the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cellular respiration is the process by which organisms (animals and plants) break down sugar in the presence of oxygen in order to release energy in the form of ATP. As a byproduct of this process, carbon dioxide and water are produced.
Cellular respiration reactions are classified into three stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and electron transport chain.
The correct option is D.

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

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.
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.
