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.

How do you think scientific method can be used to measure the rate of photosynthesis
Answer:
Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening.
Release of O2: The amount of O2 produced during photosynthesis can be measured.
Dry matter content: Dry matter is comprised of all the solids in a plant minus the water content. These solids are all produced as a result of photosynthesis. So, dry matter can be used to measure this process.
Carbohydrate production: This is an indirect way of measuring photosynthesis by its products. Parts of a plant can be harvested, dried and weighed at intervals. The difference in weights gives the increase in carbohydrates (sugars) due to photosynthesis.
Measure light-dependent photosynthesis using Hill’s reaction: In the first step of photosynthesis, oxygen is produced by chloroplasts by splitting water molecules using energy from light. Using dichlorophenolindophenol (DCPIP) as the terminal electron acceptor of oxygen atoms, Hill’s reaction measures the light-dependent phases of photosynthesis.
Chlorophyll fluorescence: When chlorophyll absorbs light, its molecules are raised to an “excited state”. It returns to its normal state by releasing the energy. Part of this is used to power photosynthesis; another portion is emitted as radiation called flourescence radiation. Since flourescence radiation is complementary to photosynthesis it is used to measure it in higher plants as well as algae and bacteria.

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.

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
