Newton's Universal Law of Gravitation states that each particle in the universe attracts every other particle with a force that is directly proportional to their masses and inversely proportional to the distance squared between them. Newton's formulation is essential for understanding gravitational forces in classical physics and is foundational for calculating planetary orbits and terrestrial gravity.
Understanding Newton's Law of Universal Gravitation
Sir Isaac Newton formulated the Universal Law of Gravitation, which revolutionized our understanding of how objects in the universe interact through gravity. This law states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses. This gravitational force is also inversely proportional to the square of the distance between the particles.
The formula for Newton's universal law of gravitation can be expressed as F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two particles, and r is the distance between them. This law has been key to understanding celestial mechanics and is a cornerstone of classical physics. It is also the fundamental principle understanding the orbits of planets and the behavior of objects under the influence of gravity on Earth.
However, it's important to recognize that Newton's law was later supplemented by Einstein's theory of general relativity, which gives an even more accurate description of gravitational phenomena, especially near very massive objects or at very high velocities. Nonetheless, Newton's law of universal gravitation remains a crucial tool for common gravitational calculations in everyday situations where general relativity has negligible impact.

1. What are things to look for to know if an example or idea is science or nonscience? 2. If the force of gravity on an object increases, what happens to its weight? 3. What would happen to the density of an object if the volume decreased while the mass stayed the same? 4. Explain: What are physical properties? Describe the two types with examples. 5. Why should procedures in an experiment be detailed for each step?
For Question 1, Ideas that are Science based, are often testable, verifiable, can be falsified, and based on evidence.
Ideas that are non-science based are not testable, not verifiable, said to be infallible and are based on belief.
For Question 2, The gravitational force increases as the size of an object increases. On the other hand, the strength of gravity is inversely related to the square of the distance between two objects.
For Question 3, The equation from density is mass over volume.
Changes volume it will change by a inverted proportion. Increases it will decrease the density, decreasing it wil increase the density.
Changes mass it will change directly. Increasing mass it will increase density and vice versa.
For Question 4, Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density.
For Question 5, I'd say it's for proof of their theory.

What is the difference between the axial and appendicular skeleton?
The axial skeleton forms the central axis of the body, consisting of 80 bones that include the skull, spine, and thoracic cage, and is crucial for protection and supporting the head, neck, and back. The appendicular skeleton consists of 126 bones in the limbs and girdles, providing the necessary structure for movement and attaching limbs to the axial skeleton.
Explanation:Difference Between Axial and Appendicular Skeleton
The human skeleton is primarily divided into two key parts: the axial skeleton and the appendicular skeleton. The axial skeleton is the central core of the human body and is comprised of 80 bones. It includes the skull, vertebral column (spine), and the thoracic cage (ribs and sternum).
The axial skeleton serves to protect the brain, spinal cord, and the organs in the chest. It also provides attachment points for muscles that move the head, neck, and back, and those involved in respiration.
The appendicular skeleton, on the other hand, consists of 126 bones and includes all bones of the upper and lower limbs, as well as the pectoral (shoulder) and pelvic girdles. This division of the skeleton is essential for movement, as it encompasses the bones that are responsible for locomotion and manipulation of the environment. The appendicular skeleton connects to the axial skeleton through the girdles.
The pectoral girdle anchors the upper limbs to the thoracic cage, while the pelvic girdle secures the lower limbs to the vertebral column. These girdles function as attachment points for the limbs and facilitate a wide range of motion.
The axial skeleton forms the central axis of the body, including the skull, vertebral column, and thoracic cage, and the appendicular skeleton includes the limbs and girdles that attach limbs to the axial skeleton.
Explanation:Difference Between Axial and Appendicular SkeletonsThe axial skeleton and the appendicular skeleton are two major divisions of the human skeletal system with distinctive functions and structures.
The axial skeleton forms the central axis of the body and primarily includes the skull, vertebral column, and thoracic cage. It supports the head, neck, back, and chest, thus forming the vertical axis of the body. The adult axial skeleton comprises 80 bones that are crucial for protecting the central nervous system and the organs in the chest.
The appendicular skeleton, on the other hand, consists of 126 bones. These include all the bones of the upper and lower limbs, in addition to the pectoral and pelvic girdles which attach the limbs to the axial skeleton. The bones in the pectoral girdle anchor the upper limbs to the thoracic cage, while the pelvic girdle attaches the lower limbs to the vertebral column.
Overall, these divisions allow the body to perform a wide range of movements and provide the necessary support and protection for various bodily functions.

The nose has mucus, a sticky substance. When outside air passes through the nose, the mucus . Bronchitis, an inflammation of the bronchioles, is a condition in which the bronchioles are filled with mucus. When mucus accumulates, .
i need to fill in the blanks
1. The right answer is the mucus filters the air.
Mucus are different viscous and translucent secretions, little or not very soluble in water, produced by specific glands of various organisms, and in these by various internal organs (eg by the goblet cells of the stomach) or internal mucosa or skin (eg fish, some amphibians, slugs, snails ...).
In humans, mucus produced in the lungs helps to protect the respiratory system by capturing and exporting many of the foreign particles that enter the nose or mouth with each inhalation. In response to inhalation of particles or allergens, mucus secretion increases (reflex and neurohumoral control process), excessively sometimes (in allergic or asthmatic patients).
2. The right answer is less air reaches the lungs (or it blocks the passage of air to the lungs).
Bronchiolitis is an acute infection of the lower airways of viral origin, affecting the small bronchi of infants and young children and spreading in a seasonal epidemic mode.
The clinical picture is due to an obstruction of the airways, on the one hand caused by a mucous plug obstructing the light, on the other hand due to inflammation of the wall. The mucous plug is created by the accumulation of dead cells and mucous secretions. The obstruction is only slightly related to the bronchial spasm, the smooth muscles being little developed at this age.
Answer:
filters the air and less air reaches the lungs

Glycolysis provides the pyruvic acid molecules used in fermentation
Glycolysis converts glucose into pyruvate, fueling cellular energy production through fermentation pathways.
Glycolysis is a metabolic pathway that breaks down glucose into pyruvate molecules, providing energy for the cell. In fermentation, pyruvate is converted into other molecules to regenerate NAD+ so glycolysis can continue without oxygen. Fermentation pathways use organic molecules as final electron acceptors derived from pyruvate.
In some instances, humans breed animals that are close relatives to produce desired traits. This is called
Artificial selection refers to the process by which humans selectively breed animals with close relatives to enhance certain traits, a common practice in domestication. This selection can affect genetic diversity and requires careful management to avoid health problems due to increased homozygosity.
When humans breed animals that are close relatives to enhance certain traits, this process is called artificial selection. This selective breeding is a common practice in domestication, where species are bred to accentuate traits that are beneficial to humans. For example, a farmer might only breed sheep with the softest wool or dogs with specific temperaments to create or maintain specific breeds. This is different from assortative mating, which is a natural tendency among species to mate with individuals that resemble themselves in some way.
Artificial selection can lead to a change in genetic diversity within a population, often increasing the prevalence of advantageous traits. However, it can also lead to increased homozygosity and the potential for harmful recessive alleles to surface, which is something that needs to be managed carefully to avoid detrimental health effects in the animals.

There are several mechanisms through which reproductive isolation occurs. Which situation is an example of behavioral isolation? A. Red and purple sea urchins cannot reproduce with one another because the sperm and egg cannot fuse. B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences. C. The reproductive organs of snails only properly align when the male and female belong to the same species. D. Mules, the offspring of a male donkey and a female horse, are unable to reproduce because they are sterile.
Answer: B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.
Reproductive isolation refers to the inability of the members of a species to breed with members of other species. Behavioral isolation is a type of reproductive isolation, in which mating between the members of the species is facilitated by their behavior. It helps members of the same species to identity their mates. It prevents mating between population of distinct species.
Males of different, closely related species of fireflies signal for mates by flashing different light sequences is an example of behavioral isolation because flashing of light by fireflies is the behavioral characteristic which shows their desire for mating. The mates identify the light signals flashed by their partner belonging to the same species.
