Desmids move by using extensions of their cell called pseudopods, which help them glide along surfaces or through water. These pseudopods are temporary projections that can be retracted and extended to change direction and move the desmid around.

The three main parts of the scientific process are hypothesis formation, experimentation, and data analysis. Scientists use these steps to test ideas and theories, gather evidence, and draw conclusions based on their findings.

Mass does not change with changes in altitude or elevation. Weight on the other hand does change. However, on earth the change from sea level to the top of a mountain would be extremely small.

The planet with a surface covered three fourths in water and ice is Earth.

The ancient Greek philosopher Thales is credited with proposing that everything in the world is made of water. Thales believed that water was the fundamental substance underlying all matter, a concept known as the "principle of water."

A location that is 60 degrees north and 100 degrees west is in Canada, specifically in the northern part of the province of Saskatchewan. This would be north of the city of Saskatoon in a remote, sparsely populated area.

When salt particles dissolve, they form bonds with the water particles. If you're looking at NaCl ... the Na and Cl will separate and hang on to other separated particles in the solution. If we're looking at salt dissolving in the water, the Na will bond with an OH... so they're NaOH, and the Cl will bond with an H. Reasons for this bonding is because of they're charges, Na having a positive charge, OH with a negative charge... opposite attract and BAM! They bond. Cl- ion will have a negative charge and the H+ is a proton thus a positive charge and BAM! They bond.

Color, luster (appearance of light reflecting off the surface), streak (color of a mineral in powdered form), hardness (ability to resist scratching), cleavage (tendency to break along flat surfaces), and specific gravity (density compared to water) are physical characteristics used to identify minerals.

DNA base pairs, genes, chromosomes, nucleus.

The water that flows in streams and rivers into the ocean and lakes is called runoff or freshwater.

When plates move laterally past each other, it can result in earthquakes along plate boundaries. The lateral movement can lead to friction and stress along the plate boundaries, which are eventually released in the form of seismic waves during an earthquake. This type of plate movement is commonly associated with transform plate boundaries.

The mass movement that makes a pattern of wrinkles or terraces on hillsides is called creep. Creep is the slow, gradual movement of soil and rock downhill due to gravity, causing a step-like pattern on the hillside.

The formal charge on the oxygen atom in NO is 0. Nitrogen contributes 2 valence electrons, and oxygen contributes 6 electrons. Since there are no formal charges assigned to N and O in NO, the formal charge on O can be calculated as 6 valence electrons - 6 non-bonding electrons - 2 bonding electrons = 0.

If you'll go to the main page for the SCIENCE category on WikiAnswers and look

under the big word SCIENCE at the top of the list of sub-categories, you'll see a

statement there that nicely wraps up the essence of Science. Past that, it's really

not the purpose of WikiAnswers to do your homework for you. That would be a

terrible thing to do to you, because it would ruin your chance to learn something.

The crops typically grown in steppes include wheat, barley, oats, and sunflowers. These crops are well-suited to the dry and windy conditions found in steppe regions, making them ideal for agriculture in these areas. Additionally, some fruits such as apples and apricots may also be cultivated in fertile steppes.

When hot magma pushes up from the Atlantic ridge, (A large,under water volcanic mountain range in the middle of the Atlantic Ocean) it has to go somewhere, so it pushes out and slowly forces the continents to move over the magma below it. Tey only move about as fast as fingernails grow, though.

A ground via is a type of via used in printed circuit boards (PCBs) to connect a signal or component on one layer to the ground plane on another layer. This helps to provide a low impedance path for returning currents and preventing signal interference. Ground vias are essential for maintaining signal integrity and reducing electromagnetic interference in high-speed digital circuits.

Yes, With a really big ruler? No, not quite. There are two ways in which scientists quantify the size of earthquakes: magnitude and intensity.

Magnitude is a measure of the amount of energy released during an earthquake, and you've probably heard news reports about earthquake magnitudes measured using the Richter scale. Something like, "A magnitude 7.3 earthquake struck Japan today. Details at ten." Did you ever wonder why, if it's that important, they just don't tell you right away?

The Richter scale was invented, logically enough, in the 1930s by Dr. Charles Richter, a seismologist at the California Institute of Technology. It is a measure of the largest seismic wave recorded on a particular kind of seismograph located 100 kilometers (about 62 miles) from the epicenter of the earthquake.

The majority of the Earth's water is saltwater found in oceans. Only a small percentage, about 2.5%, is freshwater. However, much of this freshwater is frozen in ice caps and glaciers, or stored underground in aquifers, making only a small percentage of freshwater readily available for human use.

There is no specific place on earth known as "heaven." The term "heaven on earth" is often used metaphorically to describe a place or experience of extreme beauty, joy, or happiness. The perception of what constitutes a heavenly place can vary greatly from person to person.

When another charge is added to the system, the electric field due to the first charge will be affected. The electric field will combine or interfere with the new charge's field, resulting in a new overall electric field in the region. The strength and direction of the electric field at a point will be determined by the superposition of the fields due to each individual charge.

pChanges in bonding arrangements between atoms and molecules result in absorption or release of heat (called latent heat). For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.

There is always 50% of the Earth facing the sun and 50% NOT facing it. If you
happen to be on the half that's not facing the sun, you would call that "night".

Stratovolcanoes are considered the deadliest type of volcano in the world because they are capable of producing explosive eruptions with pyroclastic flows, ash clouds, and lahars. These eruptions can cause significant destruction to surrounding areas and have resulted in some of the most devastating volcanic disasters in history.

1. Contour lines: These lines connect points of equal elevation on a map and help depict the shape of the land surface.

2. Latitude and longitude lines: These lines form a grid on a map to establish the precise location of a point on Earth's surface.

3. Borders: These lines define the boundaries between different countries, states, or regions on a map.
