D: Cells come from pre-existing cells.
This cannot be true as some cells die, meaning they cannot come from pre-existing cells.
In regards to B and C most are undiffereniated and any living thing has at least one cell in them.
During osmosis, solvent particles move from an area of ____________ concentration to an area of ____________ concentration. When there is a higher concentration of solvent particles inside the cell, most solvent particles will move ____________ the cell and the cell will ____________. When there is a higher concentration of solvent particles outside the cell, most solvent particles will move ____________ the cell and the cell will ____________.
Answer:
During osmosis, solvent particles move from an area of lower concentration to an area of higher concentration. When there is a higher concentration of solvent particles inside the cell, most solvent particles will move outside the cell and the cell will smaller. When there is a higher concentration of solvent particles outside the cell, most solvent particles will move inside the cell and the cell will larger .
Explanation:
OSMOSIS -: Osmosis is the spontaneous net migration of solvent molecules into a area of higher solute concentration through a selectively permeable membrane in the direction that appears to equalize the concentrations of the solution on both sides. It is possible to produce osmosis to do work.
For several purposes, osmosis is essential for cells. It assists in the movement within and out of the cell of essential materials. By the mechanism of osmosis, the nutrients, water and other solutes pass in and out of the cell.
An example of osmosis happens when a semi-permeable membrane separates a sugar solution and water at the surface. The big sugar molecules of the solution can't move into the water through the membrane. Until equilibrium is formed, at the bottom , small water molecules pass through the membrane.
Solvent particles move from an area of Lower concentration to
An area of Higher concentration
Most of the solvent particles will move outside of the cell and
The cell will become smaller .
Most solvent particle will move inside the cell and
The cell will become Turgid .
Osmosis is the movement of solvent molecules from a region of lower solute concentration ( i.e. high solvent potential ) to a region of higher solute concentration through a semipermeable membrane. When the concentration inside a cell is higher than the concentration ( solvent concentration ) of the environment in which the cell is placed in, the solvent particles will move outside the cell into the environment and this will cause the cell to experience plasmolysis ( shrinking of the cell ). while
When the solvent concentration in the cell is lower than the solvent concentration of the environment in which the cell is placed the solvent particles from the cell will move into the cell causing the cell to become turgid.
Hence we can conclude that the correct answers that fills up the missing spaces are ; Lower, Higher, outside, smaller, Inside and Turgid

C. The cell membrane contains proteins and lipids, but not carbohydrates.
D. A phospholipid bilayer forms the semipermeable cell membrane.
I hope that this helps you!
The correct statements that describe the structure of cell membrane are:
Proteins, lipids, and carbohydrates are found in and on the cell membrane.A phospholipid bilayer forms the semipermeable cell membrane.The plasma membrane or cell membrane of organisms is made up of a bilayer of phospholipids in which proteins, carbohydrates, glycoproteins, and glycolipids are embedded. In animal cells, there is cholesterol too.
The biological membranes of cells are made up of two layers of phospholipid. Each layer contains a lipid tail attached to a polar head. The head is polar in nature directed both outward toward the environment of the cell and inward toward the cytosol.
In this way, a hydrophobic region of lipid tails separates the solution into two parts. That makes it a semipermeable membrane.

Using the weather data in Table 1, create a 12-hour general weather forecast for the next day following the data collected.
Questions and Conclusion
1. Write a summary of the weather that occurred during the 24 hours in Table 1.
2. What are the possible sources of error in the weather data?
3. What relationships do you notice between temperature, dew point, humidity, cloud cover, and air pressure? Provide evidence for these relationships from data in Table 1.
4. In conclusion, how did your graphs support or contradict your 12-hour forecast for the following day?
5. Describe additional data you could collect to make your forecast more reliable.
6. What did you learn about weather forecasting by completing the activity(optional to answer, but an idea for something to write as a response would help)
Explanation:
1. During the day, the earth is heated by the sun. If skies are clear, more heat reaches the earth's surface (as in the diagram below). This leads to warmer temperatures.However, if skies are cloudy, some of the sun's rays are reflected off the cloud droplets back into space. Therefore, less of the sun's energy is able to reach the earth's surface, which causes the earth to heat up more slowly. This leads to cooler temperatures.When forecasting daytime temperatures, if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.At night cloud cover has the opposite effect. If skies are clear, heat emitted from the earth's surface freely escapes into space, resulting in colder temperatures.However, if clouds are present, some of the heat emitted from the earth's surface is trapped by the clouds and reemitted back towards the earth. As a result, temperatures decrease more slowly than if the skies were clear.When forecasting nighttime temperatures, if cloudy skies are expected, forecast warmer temperatures than you would predict if clear skies were expected.
2. The possible sources of error are human error and misreading the data.
3, As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases. High relative humidity of the air occurs when the air temperature approaches the dew point value.
4. When forecasting if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.
5. A more reliable approach to weather forecasting is known as the steady-state or trend method. This method is based on the knowledge that weather conditions are strongly influenced by the movement of air masses that often can be charted quite accurately.
6. Weather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes (through meteorology) to determine how the atmosphere evolves in the future

The evolution of a species is dependent on changes in the genome of the species. Identify two mechanisms of genetic change, and explain how each affects genetic variation.
Answer:
Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.
Explanation:
There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:
1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.
2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.
Two mechanisms or vehicles through which genetic change occurs are;
Mutation and Gene flowMutation occurs when there is a mistake in the DNA sequence of an organism. When an egg and a sperm bearing the faulty DNA sequence mate, a mutated organism is formed.
A standing genetic variation is formed through mutation because of the differences in the organisms of a population.
Phenotypes that indicate the physical appearance of organisms change during mutation.
Gene flow is another channel for genetic change. It occurs when two populations with different allele frequencies unite in the same environment and then assume similar allele frequencies.
When mating occurs, the allele frequencies of these populations can assume similarity.

what are the photosynthesis and respiration reactions? (i need a short answer)
Answer:
Reactions to respiration is -Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products.The reaction to photosynthesis is -process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

compare an contrast inner planets and outer planets
Answer:
Both the inner and outer planets must have created using an intense amount of force and collision
Explanation:
Collisions between bodies have occurred continually up to the present day and have been central to the evolution of the Solar System. The positions of the planets might have shifted due to gravitational interactions
The inner and outer planets differ in position, size, compositions, densities, atmospheres, and moon.
The four planets in our solar system that are closest to the Sun are referred to as inner planets, sometimes known as terrestrial planets or rocky planets. Mars, Venus, Mercury, and Earth are among these planets.
The four planets in our solar system that are furthest distant from the Sun are referred to as outer planets, gas giants, or Jovian planets. These planets include Neptune, Jupiter, Saturn, and Uranus.
The positioning, sizes, compositions, densities, atmospheres, and moon systems of inner planets differ significantly from those of outer planets. Inner planets have fewer moons, are smaller, more rocky, denser, have a variety of atmospheres, and are located closer to the Sun. The sun-farther, bigger, gaseous, less dense, widespread, hydrogen- and helium-dominated atmospheres, and numerous moons of the outer planets all contribute to their distance from the sun.
Hence, the inner and outer planets differ in position, size, compositions, densities, atmospheres, and moon.
