What is the difference between diffusion and osmosis?
Answer:
Osmosis is the movement of solvent particles across the a semipermeable membrane from a dilute solution into a concentrated solution.
Diffusion is the movement of particles from an area of higher concentration to lower concentration.
Explanation:
The overall effect is to equalize concentration throughout the medium.

During photosynthesis and cellular respiration, plant cells carry out processes that involve both light energy and chemical energy. Sort each tile into the correct column. Light energy, Chemical energy. Released through cellular respiration, used to directly power photosynthesis, captured by chlorophyll, used to directly power cell growth
Answer:
Light Energy: used to power photosynthesis, captured by chlorophyll
Chemical energy: Released through cellular respiration, used to directly power cell growth
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions.
Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms. ATP is then transported throughout the chloroplast and used to provide the chemical energy necessary to power other metabolic reactions.They take sunlight and combine carbon dioxide (CO₂) and water (H₂O). They create glucose (C₆H₁₂O₆) and oxygen gas (O₂). By this process, plants change energy from the sun into glucose. The reverse of this process is cellular respiration.Thus, Light energy is used to directly power photosynthesis and Chemical energy is released through cellular respiration.

What type of light is trapped in the Green House
Answer:
infrared light
Explanation:
The Earth absorbs this energy from the Sun and reemits it in the form of invisible infrared light. This energy is trapped by the greenhouse effect. Greenhouse gases have various shapes that make them effective at absorbing infrared radiation emitted by Earth.
It is a light called an infrared light.
Only the light in the visible spectrum can penetrate into the greenhouse whereas incoming infrared light, which is also known as heat radiation, is blocked by the glass or plastic.

PLEASE HElp 15 points If a scientific idea has been proven 100% of the time, like gravity, it becomes a blank
whereas an idea that is generally believed but has not been proven to be 100% true would be called a blank
Answer:
If a scientific idea has been proven 100% of the time, like gravity, it becomes a theory, whereas an idea that is generally believed but has not been proven to be 100% true would be called a hypothesis
Explanation:
In scientific research, a hypothesis is an idea put forward before any research has been completed. It is based on previous data, and requires scientific testing before it is confirmed and becomes a theory.
A theory is a principle put forward to explain a range of observations. For example, multiple lines of evidence support the theory of evolution. There is no significant data that refutes the theory.

What must match between a virus and a host cell?
A)DNA= Cell DNA
B)RNA=ribosome
C)envelope proteins= cell receptors
D)blood types
Answer:
C)envelope proteins= cell receptors
Explanation:
To enter the cell, the virus must bind to receptor proteins on the cell surface It does so via its envelope proteins. When the receptors and the envelope proteins match, the virus can become engulfed into the cell.
Once it enters the cell, the hijacks the cell's transcription and translation machinery and causes the viral proteins to be expressed. The viral proteins assemble into viral particles. Eventually, the cell bursts and the viral particles are released.
A virus has a nucleus and other organelles
True
False
Answer:
False it just have a false nucleus surrounded by a protein
Answer:
False
Explanation:
A strain of bacteria possesses a temperature‑sensitive mutation in the gene that encodes the rho subunit. At high temperatures, rho is not functional. When these bacteria are raised at elevated temperatures, what would you expect to observe?
a. All RNA molecules are shorter than normal because the absence of functional rho would derail the transcription.
b. Transcription does not take place because mutant rho would interfere with the RNA polymerase binding to the template.
c. Some RNA molecules would be longer than normal because these RNA came from the gene with rho-dependent terminator.
d. Some RNA molecules would be normal length because not every terminator in bacterial genes would be rho-dependent.
e. All RNA molecules are longer than normal because the absence of functional rho means the transcription continues beyond the proper termination point.
Answer:
d. Some RNA molecules would be normal length because not every terminator in bacterial genes would be rho-dependent.
Explanation:
Rho is a prokaryotic protein which is required at the end of transcription (termination) of dependent rho-terminator sequences. During transcription, Rho binds at the end of the single-stranded RNA sequence in a site known as 'transcription terminator pause site'. This factor has helicase activity dependent on the hydrolysis of Adenosine triphosphate (ATP) to ADP. The Rho binding site consists of a cytosine-rich region (∼ 70 nucleotides) that lacks RNA secondary structure.

What is evolution?
Answer:
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Explanation:
What prevents a lake or ocean from freezing solid?
Answer:
The surface layer of the water freezes solid creating a barrier that insulates the ice below so that it keeps a steady temperature usually a few degrees above freezing (32 degrees).
Explanation:
Mrs. Strunk's Earth Science class used an erosion model to investigate the relationship between the slope of a hill, or incline, and the amount of soil that washes off of the incline. The class increased the slope of the incline from 1 to 5. Then, they poured 100 ml of water down the incline. Finally, they collected the soil from a tray at the bottom of the incline, dried the soil in an oven, and used a balance to find the mass of the soil. The data from their study is shown below. Based on the graph, more soil is washed away when A. there are fewer rocks in the soil. B. the slope of the incline is steeper. C. the soil is made mostly of sand. D. the slope of the incline is less steep
Answer:
B. the slope of the incline is steeper.
Explanation: Cause i guessed and got it right.
Answer: it would be, b the slope of the incline is steeper.
