What is a macro environment analysis?

Political factors are used to inspect the political situation of a country and the extent of government intervention. This includes the government policy, laws, trade restrictions or any tariffs established by the government. Meanwhile, economic factors refer to the determinants of an economy’s performance, such as rate of interest, exchange and inflation. The economic factors may affect business decisions of the organization.\nSocial factors include the social environment of the area, such as demographics, cultures or populations. Technological factors deal with several areas, such as the r..

What gives urine a sulfur smell?

Asparagus contains asparagusic acid, which breaks down into various sulfur-containing compounds, such as dimethyl sulfide, upon digestion, says Smithsonian. Similar compounds are responsible for the pungent odor of garlic and skunk spray. These sulfur compounds are volatile and enter their gaseous phase at room temperature, releasing odor as soon as urine comes into contact with air. Asparagusic acid is not volatile, so the vegetable itself does not produce the same odor. Asparagusic acid breaks down quickly, however, and sulfur compounds appear in urine as soon as 15 minutes after consuming a..

What creates the skeletal muscle cell's striated appearance?

PearsonHigherEd.com explains that each sarcomere is separated from its neighbors by Z lines, boundaries to which thin muscle filaments are attached. These thin filaments run from the Z line to which they are anchored toward the center of the sarcomere, but they do not run all the way to the Z line on the opposite side. Thick filaments rest within the center of the sarcomere and touch neither Z line. They partially overlap the thin filaments. The two regions on either end of the sarcomere that contain only thin filaments are called I bands, The region in the center with only thick filaments is ..

How does a potato battery work?

Potato batteries require two different metal electrodes with different electrical qualities to work. The most common materials are zinc and copper. The acids in the potato react with the metals, creating an electron imbalance at each electrode. Because it keeps the ions formed by the reaction separate, but conducts electricity via its water and electrolytes, the reaction forces the electrons in the copper electrode to move. This movement of electrons is an electric current and is sufficient to power small devices.\nSome scientists have actually researched potatoes as a practical form of power...

What happens when dopamine receptors are blocked?

The effects of blocking dopamine receptors range from mild to severe, and the impact varies based on the specific receptor being blocked. Dopamine activates the D1 to D5 dopamine receptors. Of particular interest to researchers is the D2 receptor, because it is thought to play a significant role in addiction. Researchers at the National Institutes of Health, specifically the National Institute on Alcohol Abuse and Alcoholism, found that D2 receptors help to prevent production of excessive behaviors and limit the rewarding effects of food and cocaine. Blocking these receptors, therefore produce..

How fast does the wind blow in a hurricane?

Though very intense tropical systems have occurred in the Atlantic and eastern Pacific basins, the strongest cyclones on record originated in the western Pacific basin. Super Typhoon Nancy in 1961 holds the record for strongest cyclone on record with maximum sustained winds at 215 mph. The strongest cyclone ever in the Atlantic and eastern Pacific basins was Hurricane Wilma in 2005 with maximum winds of 185 mph.

What do stoneflies eat?

There are 3,000 species of stoneflies worldwide, and different breeds have slightly different habitats and preferences. Most stonefly species are very inconspicuous insects. They spend most of the day hiding amongst vegetation. At night, they take flight and look for mates. When depositing their eggs, the females place them in water. Most stoneflies inhabit the rapidly flowing portions of rivers and streams. Such places have higher levels of dissolved oxygen, which the stonefly larvae require for growth. Usually, the larvae will crawl under rocks for protection from predators and the swift cur..

How many valence electrons does oxygen have?

Oxygen is a tasteless, odorless and colorless gas. Its chemical symbol is O and it is atomic number 8 on the periodic table of elements. It is highly reactive and combines with most other elements to form compounds, especially oxides. Some common oxides include carbon dioxide (CO2), nitrous oxide (N20) and iron oxide (Fe3O4).\nAfter hydrogen and helium, oxygen is the third most abundant element in nature, and the mass of the human body is approximately two-thirds oxygen.

What is a distilling flask?

Distilling flasks are typically made from Pyrex, a glass material that can withstand high heat. This makes them ideal for the distillation process, which requires the contents of the flask to be heated. As the components are heated, each changes in turn from a liquid to a gas. The molecules then move through the sidearm of the flask into a condenser.

How do Euglena get rid of waste?

The cytosol of the plasma membrane of euglena makes them always hypertonic to their surrounding aquatic environment. This enables water to flow freely across the plasma membrane, facilitating the expulsion of waste from the vacuole. Contractile vacuoles consist of two sub-compartments, each of which is encircled by a different membrane. One membrane is divided into minute tubules and vesicles containing proton-translocating enzymes that enable active transport of components in and out of the protozoa. This active transport involves the generation of an electrochemical gradient though the membr..
