Population

Population is the number of people who inhabit a particular place. Population is influenced by physical environment, settlement patterns, economic activities, and the history of an area.

Before the 19th Century

  • Climate changes around 10,000 years ago led to the Neolithic Revolution. As agriculture developed and population became more sedentary, towns and cities were established. Population grew slowly because it was dependent on the resources available.
  • Wars, epidemics, and large-scale migration also either limited or promoted population growth. In the first century A.D. the world population was about 256 million. It increased until the Black Death of 1342. By the mid-17th century, the world population surpassed 500 million, and in 1800

THE MILLER-UREY EXPERIMENT

  1. They introduced the gases Oparin believed existed in the primitive atmosphere into a chamber.

  2. Then they ran electric currents through it to simulate the energy from lightning.

  3. The products created by the chemical reactions that took place in the chamber collected in a container that imitated the 'primitive ocean'.

  4. When they extracted the liquid of the 'primitive ocean' and analyzed it, they observed biomolecules that had formed from the simple inorganic products.

Blood: Functions and Composition

Blood is a type of connective tissue. It is a thick red liquid made up of specialized cells suspended in a watery solution of molecules and ions. Blood transports nutrients and oxygen to the cells and carries waste residues to where they can be eliminated. Besides that, it regulates body temperature, pH and water volume, transports hormones, and defends our body from infections or from excessive blood loss when we get wounded. Blood is the only liquid tissue in our body because the matrix in which blood cells are immersed is liquid. The liquid component of blood is called plasma and it represents about 55% of blood volume.

Plasma: Composition and Role

Plasma is a pale yellow liquid. About 90% of it is water. The... Continue reading "Human Blood: Composition, Functions, Cardiac Cycle & Edema" »

Classified in Chemistry

Written on in English with a size of 3.52 KB

Chemical Change vs. Phase Change

Chemical change: Produces new substances that didn't exist before.

Phase change: The substance remains the same before and after the process.

Dissolving: It is only a homogeneous mixture; no new substances appear.

Identifying Chemical Changes

How do we know if a chemical change is occurring?

  • Gas release: Gases may not be visible; we identify them by bubbles in a liquid.
  • Color change
  • Thermal energy change
  • Energy release as light

Understanding Chemical Reactions

A chemical reaction occurs when the starting substances, called reactants, transform into other new substances, called products.

The appearance of new substances is due to the rearrangement of the reactant's atoms, forming the products. The information about a chemical... Continue reading "Chemical Reactions and Their Impact on Industry" »
