Use your knowledge of osmosis to explain why the mass of each cube increased.
Answers
Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass
The mass of each potato cube increased because they have gained water by osmosis.
Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.
A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).
Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.

Answers
Answer:
It is located in the sun's green zone where habitability was and still is possible, this allowed the earth to develop various types of life. With varying climates this supported adaptations which later morphed the flora and fauna of our home planet.
Scientists use a process called gel electrophoresis to separate DNA fragments. The process involves placing a mixture of DNA fragments at one end of a slab of porous gel. Then a power source is used to generate an electric potential across the gel.
The diagram shows the process of gel electrophoresis. First, DNA fragments, mixed with a restriction enzyme, are placed at one end of a slab of gel. Then a power source is applied; the longer DNA fragments stay near the negatively charged end, and the shorter fragments move toward the positive end.
Gel electrophoresis is successful because of which property of the DNA fragments?
A. The DNA fragments may be positively-charged, negatively-charged, or neutral.
B. The DNA fragments travel at different speeds through the gel.
C. The DNA fragments travel at the same speed through the gel.
D. The DNA fragments chemically react with the gel in different ways.
Answers
Answer:
C. The DNA fragments travel at different speeds through the gel.

The best and most correct answer among the choices provided by your question is the fourth choice or letter D "The thin membrane that closes the cavity of the middle ear from the outside changes position."
Your ears pop in airplanes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down. Your inner ear has air trapped in it and as the atmospheric pressure changes, it causes pressure on your eardrum.

Which of the statements are characteristics of a good hypothesis? -is developed from data that cannot be replicated -relies heavily on cutting edge technology -is created from careful research and logical reasoning -is based only on a presentation by an expert in the field -is able to be tested using validated techniques
Answers
Answer:
is created from careful research and logical reasoning
is able to be tested using validated techniques
Explanation:
A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.
