Are plants unicellular or multicellular?

In addition to multicellularity, all plants share several other characteristics. They are capable of making their own food through a process called photosynthesis, which involves absorbing light energy from the sun and converting it to chemical energy stored in carbohydrates. All plant cells have cell walls comprised of a carbohydrate material called cellulose, and they have the ability to grow larger through cell division. Plants lack motility. They reproduce both sexually and asexually.\nPlants are divided into four main phyla based on shared characteristics.\nThe Phylum Bryophyta contains p..

What is a complete ionic equation?

Ionic equations involve electrolytes that dissolve in water. They include single and double displacement reactions. They sometimes form insoluble salts that precipitate from the solution or gases that bubble out of the water. For example, most carbonates are insoluble with a few exceptions. Sodium carbonate dissolves in water but reacts with barium to form an insoluble precipitate. In double replacement reactions, all the ions from the dissolved electrolytes take part in the reaction, so there are no spectator ions. In these reactions, the net ionic equation and the complete ionic equation are..

What are all the different landforms?

A landform is a part of the Earth's surface that exists naturally, meaning it is not human-made. This makes all natural terrain landforms of one type or another. The type of landforms common to an area are dictated by global geo-history, weather conditions and other factors. Hills, mountains, gulches and bayous are all landforms. The four hierarchical layers of landforms are oceans and continents, landform elements, terrain and elementary landforms.Oceans and continents are the largest and highest-order landforms. Landform elements are features of these high-order landforms that can be mo..

What is blue clay soil?

In the United States, blue clay soil is predominantly found in Utah's southern region. This dried-up layer of earth is composed of extremely small particles that are associated with caliche and bentonite soil formations. The sediments comprising blue clay soil are deposited by prehistoric rivers and lakes, including materials derived from volcanic ash.Blue clay soil causes destructive effects on paved surfaces, walkways and structural foundations. Homes and other buildings that are constructed in a relatively undeveloped area are prone to serious damage.

How do you safely dispose of waste gasoline?

It is never safe to dispose of gasoline in the trash or by dumping it down the drain, into a waterway or onto the ground. This is harmful to the environment and can result in a fire. Gasoline can be safely stored, especially if a fuel stabilizer is added at the beginning of the storage period, though each engine or other gasoline-burning device has a manufacturer's recommended maximum age for the gasoline used. It is important to know that specification before adding gasoline to a car or other piece of equipment.\nThe best way to dispose of gasoline that is too old to be used varies by lo..

How are hurricanes tracked?

Satellite images are extremely important to forecasters. Satellites can put several hours of pictures into motion. This helps meteorologist gather information about the track and the development of hurricanes.\nDoppler radar helps detect rain associated with hurricanes. It covers rainfall surrounding a distance of 200 to 250 miles from the Doppler location. It also helps provide estimated rainfall amounts and helps spot rain bands, the eye and the eye wall within a hurricane.\nAircraft are used to gather information about wind speed, rainfall and the eye of a hurricane. Dropsondes are instrume..

How does algae form?

An algal bloom can occur in saltwater or freshwater sources. The ecological imbalance is caused by the presence of too much organic material from dead leaves, animal waste or grass clippings. If the amount of organic material is too high, the water loses the ability to maintain adequate oxygen levels. The absence of oxygen and the proliferation of nutrients provided by organic material allows algae to thrive. If the lack of oxygen in a body of water is severe, fish and other aquatic animals can die, further promoting algae growth.

Where did Charles Darwin go to school?

In 1809, Darwin was born into a wealthy family driven by scientific endeavors. His father was a doctor, his paternal grandfather was a free-thinking botanist and his maternal grandfather was a famous industrialist. As a child, Darwin was unsatisfied with the Shrewsbury School curriculum, which focused heavily on religion and classical education and discouraged exploratory science.\nDarwin's medical education at Edinburgh was cut short because he strongly detested studying human anatomy, handling blood and performing surgery. In 1831, he graduated from Christ's College with a bachelor..

What are some good soil facts for kids?

Soil consists of horizontal layers that naturally occur as rock breaks down and mixes with organic materials. These layers are called horizons and range from the O horizon, which is the topmost layer, to the R horizon, which is bedrock. The O horizon is made up of fallen leaves and rotted organic matter.\nPedologists – scientists who study soil – rank soil by its texture. Soil can be sandy, silty or clayey. Sandy soil has the largest particles, is not very rich in nutrients, and feels rough to the touch. Silt has the second largest particles and feels soft and powdery to the touch; it is s..

What is the difference between pure and applied science?

Pure science creates and establishes information to understand nature, whereas applied science uses this information to develop technology or techniques to change outcomes. Engineering is a dominant form of applied science, as it utilizes the findings from pure science as the basis of applications. Pure science is often referred to as natural science, basic science or fundamental science.\nExamples of applied sciences include medical sciences such as medical microbiology and genetic epidemiology, and formal sciences such as probability theory and statistics. Other examples include fluid mechan..
