1. Newton's first law of motion projects that a object at rest will remain at rest, and a object in motion will remain in motion with a constant velocity, until or unless a force is acted upon by the external environment.
2. Newton's second law of motion projects that the acceleration of an object is considered to be directly proportional to the net force acting on the object and generally inversely proportional to its mass.
3. Newton's third law of motion projects that for every action, there is an equal and opposite reaction.
The first law is also renowned as the law of inertia. The second law thoroughly distinguishes the relationship between applied force and the rate of change of momentum. And finally the third law is also know as the law of action and reaction because it depends on the type of stimulus that is experienced from the environment when the individual is applying force.

15. Two Siamese and three Persian cats survive a shipwreck and are carried on driftwood to a previously uninhabited tropical island. All five cats have normal ears, but one carries the recessive allele for folded ears (his genotype is Ff). Calculate the frequencies of alleles F and f in the cat population of this island. If you assume Hardy-Weinberg equilibrium for these alleles (admittedly very improbable), about how many cats would you expect to have folded ears when the island population reaches 16,000?

Scenario the island kingdom viti levu had a rat problem. How would you describe changes in the rat population over time by reffering to the actions of slow changing and fast changing variables
In the case of the rat problem on the island kingdom of Viti Levu, we can describe changes in the rat population over time by referring to the actions of slow-changing and fast-changing variables.
What is the rat problem?Long-term and rather slowly fluctuating variables have an impact on the rat population. Examples of slow-changing variables in this environment include the temperature of the island, the appearance of new predator species, or changes in land use that affect the amount of food and shelter available to the rats.
Although these slow-changing elements might not have an immediate impact on the rat population, they could have a significant one in the long run.

HELP ME PLEASE I NEED THIS Write in complete sentences to explain what a budget is, how to make one, and how to balance it
(No passage)
Answer: A budget is a financial plan that outlines expected income and expenses for a specific period of time. To make a budget, you need to list all sources of income and all expenses, including fixed expenses such as rent or mortgage payments and variable expenses such as groceries and entertainment. Once you have listed all income and expenses, you can calculate the difference between the two to determine if you have a surplus or deficit.
To balance a budget, you need to ensure that your expenses do not exceed your income. If you have a surplus, you can allocate the extra money towards savings or paying off debt. If you have a deficit, you will need to find ways to reduce your expenses or increase your income to balance your budget. This can be done by cutting back on discretionary spending, finding ways to save on necessary expenses, or finding additional sources of income.

which set of terms best describes a cell membrane
The cell membrane can be described using the following terms:
1-Phospholipid bilayer: The cell membrane is composed of a double layer of phospholipid molecules arranged with their hydrophilic (water-loving) heads facing outward and their hydrophobic (water-repelling) tails facing inward.
2-Selectively permeable: The cell membrane is selectively permeable, meaning it allows the passage of certain substances while restricting the movement of others. This property helps maintain the cell's internal environment and regulate the exchange of molecules with the external environment.
3-Fluid mosaic model: The cell membrane is described by the fluid mosaic model, which suggests that it is a dynamic structure composed of various components, including phospholipids, proteins, carbohydrates, and cholesterol. These components are not fixed in place but rather move and interact within the membrane.
4-Barrier: The cell membrane acts as a barrier, separating the cell's internal environment from the external environment. It helps protect the cell's contents and regulates the movement of molecules, ions, and other substances in and out of the cell.
5-Receptor sites: The cell membrane contains receptor sites that can recognize and bind to specific molecules or signals, such as hormones or neurotransmitters. This allows the cell to respond to external stimuli and initiate various cellular processes.

The laws of Mendel are three fundamental principles of inheritance that were discovered and described by the scientist Gregor Mendel in the 19th century. These laws describe how traits are passed down from parent to offspring and provide the foundation for our understanding of genetics.
The three laws of Mendel are:
The Law of Segregation: This law states that during the formation of gametes (sperm and egg cells), the two copies of each hereditary factor (allele) segregate so that offspring inherit one allele from each parent. This is also known as the principle of dominance, where one allele can be dominant over the other and determine the observable trait.
The Law of Independent Assortment: This law states that during gamete formation, the segregation of one pair of alleles is independent of the segregation of other pairs of alleles. This means that the inheritance of one trait is not influenced by the inheritance of another trait.
The Law of Dominance: This law states that when two different alleles for a given trait are present in an individual, one allele (the dominant allele) is expressed and the other allele (the recessive allele) is not expressed in the phenotype of the organism.
These laws help to explain the patterns of inheritance observed in sexual reproduction and have practical applications in the field of genetics, such as in predicting the likelihood of inherited genetic disorders and in breeding programs for plants and animals.
