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.

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.

The 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.

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.

Photosynthesis occurs in the chloroplast of plant cells. Thylakoid is a membrane-bound compartment in the chloroplast, which is the site of the light-dependent reaction of photosynthesis.

Answer:

The light dependent reaction of photosynthesis takes place in the thylakoid membrane of the the organelles called chloroplast.

The light dependent reaction uses light energy( sunlight) to make molecules required for the process of photosynthesis. Out of two one is ATP molecule and the other one is NADPH.

These two molecules along with carbon dioxide and water starts the process of photosynthesis.

During chemical reactions, the chemical bonds between the atoms in the reactants are transformed. Bonds are broken in the reactants and new ones are created in the products, leading to the transformation of substances.

During chemical reactions, the chemical bonds between atoms in the reactants undergo changes.

This occurs because chemical reactions involve processes that break down the bonds in the reactants and form new ones in the products.

This is important for the transformation of substances. For instance, water forms due to a chemical reaction where two hydrogen atoms bond with an oxygen atom.

Hence, chemical bonds play a critical role in the process of chemical reactions, facilitating the transformation of one chemical substance into another.

The parts of the alimentary canal listed in order are the mouth, pharynx or throat, esophagus, stomach, small intestine and large intestine. The alimentary canal is the digestive system and includes the parts of the body with which food comes in contact from eating to waste elimination.

The alimentary canal is the whole passage along which food passes through the body from mouth to anus. It includes the esophagus, stomach, and intestines. The intestines carry the food most of the way down, breaking down the food along they way. The intestines carry food from the esophagus to the stomach.

rocks can become soil in multiple different ways one could be primary succession which means some algae or moss grows onto rocks with out soil then they slowly gain moisture which attracts some other plants like flowers which then breaks down the rock into smaller things then grasses come in and turns it into soil.

Hello...

According to evolutionary scientists, animals that arose later in evolutionary history share which characteristic?

Answer - B. Cells organized into tissues

Living things are made of types of molecules, known as macromolecules.

There are four major classes of biological macromolecules:

carbohydrates

lipids

proteins

nucleic acids

Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.

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.

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.

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.
