When is the hurricane season in Cuba?

The hurricane season affects Cuba as well as other Caribbean countries in this region during this period.\nIn Cuba, there also are two predominant seasons: the rainy season and the dry season. While the rainy season runs from May through October, the dry season is from November through April. In this part of the world, hurricane activity tends to occur during the rainy season.\nCuba is an island in the Caribbean that has a warm climate year-round. Its location is south of Key West, Fla.

What does carbon and oxygen make?

The chemical element carbon exists in nature in several different physical forms called allotropes. Diamond and graphite are the two crystalline structures of carbon while charcoal, carbon black and coke are some of the element's noncrystalline shapes. One of the characteristics of carbon is the formation of strong double and triple chemical bonds with several nonmetallic elements, such as nitrogen, phosphorus, sulfur and oxygen.A binary compound called an oxide is produced when an element chemically reacts with oxygen in a process known as oxidation. When the oxidation process releases h..

What is the head of the carbon family known as the basis of life?

Since carbon is one of the most common elements on earth, it is unsurprising that it is the head of an elemental family. Other elements that are in the carbon family include silicone, lead, germanium, tin and flerovium. These elements are major elements in the world and make up a large part of the environment. These elements also generally stem from the same components as carbon and are in the same family.\n\nThe majority of chemicals that are in the carbon family are used for heating. Tin and lead are metal elements that are found in many applications throughout the world. They are generally ..

What are the basic building blocks of matter?

Atoms are made up of three different particles. Protons and neutrons are found in the nucleus, which is the central core of the atom. Protons have a positive charge, while neutrons have no charge.\n\nElectrons are found in energy shells outside of the nucleus. Each of these subatomic particles has a negative charge. A neutral atom contains the same number of protons and electrons.\n\nCharged atoms, called ions, form when an atom gains or loses at least one electron. If an ion has more protons than electrons, it has a net positive charge. If the ion has more electrons than protons, it has a net..

What is the function of meristematic cells?

Apical meristematic cells are found at the tips of stems and roots and are responsible for the elongation of these structures. These cells have thin cell walls, which makes the cell division process simpler. They are also notably smaller than mature cells, have large nuclei and do not have vacuoles because they do not need to store materials for long periods of time. Apical meristematic cells put all of their resources into dividing to create permanent tissues. The plant protects these delicate meristematic cells by growing leaves at the tips of stems.\nLateral meristematic cells are responsib..

How old is the universe's oldest known star?

The age of the oldest star, officially known as HD 140283, is actually impossible, since current scientific evidence shows that the universe is 13.82 billion years old. But scientists agree that although HD 140283 may actually be slightly younger than its current determined age, the star offers the most reliable age measurement of stars thus far. As new evidence becomes available, scientists continue to reassess the ages of the oldest stars in relation to the universe’s age.HD 140283 is nicknamed Methusaleh, which is also the name given to the second-oldest living tree on earth. Methusaleh r..

What is bleach made of?

A variety of oxidizing and reducing compounds are used as chemical bleaches. Oxidizing bleaches work by breaking the chemical bonds in the stain, changing the molecular structure enough to render it colorless. Reducing bleaches achieve the same result by changing the double bonds in the stain to single bonds. Ultraviolet light bleaches out color by the same process of breaking chemical bonds.

What is the imaginary line around which the Earth spins?

During the summer months, the Earth's North Pole tilts toward the sun, creating warmer weather in the Northern Hemisphere. During the autumn, both hemispheres receive roughly the same amount of sunlight, but when the North Pole tilts away from the sun, the Southern Hemisphere experiences the warmer weather. However, the Earth spins on its axis similar to the movement of a top, and the dates for shifting seasons changes very gradually, on a cycle that lasts 25,800 years. Eventually, the summer and winter seasons for the two hemispheres will switch.

What is the function of the pancreas?

The enzymes and salts in the digestive juices help the body digest proteins, sugars, fats and starches. These enzymes include lipases, which help the body digest fats, proteases, which help it digest proteins, and amylases, which break down starches into smaller sugar molecules. Proteases also help keep the small intestine free of parasites, including yeast, protozoa and parasitic worms.\nThe pancreas also has special cells called the islets of Langerhans. These islets secrete insulin into the blood stream, where it goes into the cells. It's crucial that the pancreas produce the right amo..

What is the formula for tin (IV) phosphate?

This chemical compound is composed of three tin (IV) ions, ionically bound to four phosphate ions. Each tin (IV) ion has a 4+ charge. Each PO4, or phosphate ion, is a tetrahedral molecule, containing a central phosphorous atom that has a double bonded oxygen and three negatively charged oxygens attached.Therefore, each phosphate ion has a 3- charge. For tin (IV) phosphate, the sum of all positive and negative charges equal zero.
