What bones are connected to the clavicle?

The human body has two clavicles, as well as a pair of scapulas. Clavicles are normally prominent in thin people. The clavicle, which belongs to the class of long bones, is the only long bone in the human body that lies horizontally. It can be divided into three parts: the sternal or medial end, the acromial or lateral end, and the shaft. The acromial end of each clavicle attaches to the acromion of each scapula, while each sternal end attaches to the sternum.

What is an example of a lab for finding the molar volume of a gas?

Another example of a lab for finding the molar volume of a gas uses the reaction 2KClO3(s) --> 2KCl(s) + 3O2(g), in which potassium chlorate is heated to a point where it decomposes and produces gaseous oxygen. The properly measured reaction produces known mass of oxygen gas, which can then be used to measure temperature, volume and pressure. Those values are necessary to calculate the molar volume of the oxygen with the formula V = RT/P, where V is the volume at standard temperature and pressure conditions divided by the moles of oxygen.\nEquipment needed for these labs include a 1,000-millil..

What are some common questions about science?

According to TheGuardian.com, adults have more complex questions and look to science for the answers. Such questions are:\n"What is the universe made of?"\n"Are we alone in the universe?"\n"What is consciousness?"\n"What makes us human?"\nand "What is at the bottom of a black hole?"\nSome of these questions already have scientific answers that are widely accepted. Some questions are topics of fierce debate, such as the question of what consciousness consists of. Most answers are still only theories without absolutely proof.

What is the path the blood follows through the human body starting at the right atrium?

One circuit of the circulatory system is called the pulmonary branch, and it carries blood from the heart to the lungs so that the blood receives oxygen in exchange for carbon dioxide. The systemic branch of the circulatory system transports the blood from the heart to the major components of the body. Blood travels from the heart in blood vessels called arteries, while it returns to the heart through blood vessels called veins. Capillaries are small vessels that connect arteries with veins.\nThe heart has several valves that help to ensure the blood flows in the correct direction at all times..

What law says that energy is neither created nor destroyed?

One example of this principle is the way a car changes the chemical energy of burning gasoline into the mechanical energy used inside the engine, which makes the vehicle accelerate. Another example is how the electrical energy created by a windmill is transformed from the mechanical energy of the turning blades. Since this conversion process isn't always perfect, sometimes a significant amount of energy is wasted when some energy is turned into wasted heat.

What kind of ions do metals form?

The octet rule states that atoms with eight electrons in their outermost energy levels have the most stable configuration. Atoms achieve this type of configuration by gaining or losing electrons depending on the number of electrons in their outermost energy levels called valence electrons. Atoms with few valence electrons lose them; atoms with larger numbers of valence electrons tend to gain electrons.\nNeutral atoms have no charge because the number of positively charged protons in the nucleus balance the number of negatively charged orbiting electrons; these atoms have no net charge. Metals ..

What is soil pollution?

Soil contamination occurs in several different ways. Humans sometimes bury liquids or solids in the earth as a means of waste disposal. At other times, humans pollute the ground by industrial activities, as when pollution from a smokestack spreads to the surrounding area polluting the soil as it falls to the ground. Runoff water, contaminated by the misuse of agricultural chemicals, pollutes the ground as is runs over and through it. Soil pollution affects plants, animals and humans. Plants growing in contaminated soil take up hazardous waste through their root systems. The health of humans an..

What happens when a neuron is at rest?

When a neuron is at rest, potassium ions (K+) have an easy passage through the membrane. It is difficult for Chloride ions (Cl-) and sodium ions (Na+) to cross. The negatively charged protein molecule (A-) is unable to pass through the membrane. Accompanying the selective ion channels is a pump which three sodium ions out of the membrane for every two potassium ions that enter. After all of the forces balance out and the voltage differences between the inside and outside of the neuron have been measured, then the resting potential is achieved.\nThe resting potential contains information about ..

Where did cyclops live?

Though Homer described Polyphemus' home as the island of Hypereia, that area has now been identified as Sicily, a large island in southern Italy. Some versions of the cyclops myth are much less worldly, with the one-eyed humanoids serving as godly helpers, helping to fashion lightning bolts for Zeus or helping Hephaestus work his forge.

What is the opening at the top of a volcano called?

Volcanoes are ruptures on the crusts of planets, such as the Earth. These ruptures allow hot gases and lava, as well as volcanic ash, to leave the magma chamber under the planetary surface. Volcanic vents come in a variety of shapes and sizes, depending on the gas content of the magma that leaves the volcano. Examples of these shapes and sizes include spatter vents, cinder cones and satellitic shields.
