What is the normal phase of aluminum?

Aluminum is found in period three and group 13 on the periodic table. The element is the most abundant metallic element found in the Earth's crust, but it is never found freely in nature. For this reason, all of the aluminum that is used in industry or manufacturing is man-made from other metallic elements. Potassium aluminum sulfate and aluminum oxide are two man-made sources of aluminum.

Where is bile secreted?

The gallbladder is next to the liver, and the duodenum connects the stomach to the small intestine. About 600 to 900 milliliters of bile is secreted every day. The gallbladder can store very little of the bile, but it processes the bile quickly. This process takes place continuously. Bile is acidic and helps to dissolve the fats in the food.

What is a constant in science?

Any experiment conducted according to the scientific method will have constant variables and experimental variables. Experimental variables are those variables a scientist chooses to change so she may study the effects of the change. Constants are variables that are kept the same to ensure all effects being studied and measured are the result of an experimental variable.\nIf a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent..

What is a good pH level?

Aquarium keeping is an example of a hobby where knowing the ideal pH is important. Freshwater community aquariums should have a pH of 6.5 to 7.5 because most fish are comfortable in conditions that are either neutral, slightly basic or slightly acidic. Hobbyists can use water conditioners to control pH and ensure that it is within the right range.

What do sperm whales eat?

Sperm whales dive deep for their food. Female sperm whales are known to dive down to a kilometer under the surface, and males dive deeper still in search of prey. They can remain submerged for up to an hour while they hunt. Sunlight doesn't penetrate the depth at which sperm whales hunt, so they probably don't use their disproportionately small eyes. They do, however, have a keen sense of echolocation that works to isolate prey animals in total darkness. Blind yet healthy sperm whales have been captured, which suggests that eyesight is of secondary importance to the whales in gatheri..

What is spherical symmetry?

While spherical symmetry typically involves man-made structures and geometric shapes, there are some examples that occur in nature. These examples typically include small organisms, such as Volvox, a form of freshwater alga. Spherical symmetry also depends on color patterns and other properties. While the earth is in the shape of a sphere, it would only be symmetrical if all the atmospheres, land structures and colors were symmetrical.

When do poppies flower?

California poppies grow wild and flower all summer long, but each flower only lasts a few days. Oriental poppies bloom for a very short period during late spring and early summer, with each bloom lasting about one month. Poppy mallows bloom for about ten weeks during the summer. Celandine poppies flower from April to June and are easy to propagate. So-called "super poppies" flower in June, then have a second blooming in August or September.

How are bacteria classified?

The majority of bacteria are in the cocci, bacilli or spirilla categories. In nature, bacteria can exist either as single cells or in pairs, clusters or chains. A colony of bacterial cells of a certain shape is named based on how the cells are arranged within the group. For example, the term diplococci refers to a coccus, or spherical, bacterium arranged in pairs. Meanwhile, streptococci are spherical bacteria arranged in chains, and staphylococci are spherical bacteria arranged in clusters.\nStreptococcus pyogenes and Streptococcus pneumoniae are examples of cocci that can cause illness in hu..

What are four roles that proteins play in living things?

Proteins are complex molecules that perform many critical functions in the body. They are made up of chains of amino acids, and the sequence of these amino acids determines both the type and function of the protein. Proteins are diverse are in structure, characteristics and function. Some proteins are hydrophilic, while others are hydrophobic. Some proteins frequently change shape, while others remain intact.

What are some facts about sapodillas?

Sapodilla is grown chiefly for its fruit, which is popular in the parts of Latin America where it is grown. It is eaten raw or processed into ice cream or jam. Parts of the plant, such as the leaves, have also been used in traditional medicine to treat digestive problems.\nThe other major product of sapodilla is the sap. Sapodilla sap, called chicle, is the original source of chewing gum. As of 2015, very few commercial chewing gums actually contain any chicle, but the tree is still cultivated for its rubbery sap.\nSapodilla is rarely used as lumber, although it is strong and very durable. The..
