The stratosphere is composed mostly of nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include ozone, water vapor, and trace gases like helium and methane. The exact percentages can vary slightly depending on altitude and location.

Spica is a bluish-white star, visible to the naked eye in the constellation Virgo.

No, red is not the first color on the rainbow. The colors of the rainbow, in order, are red, orange, yellow, green, blue, indigo, and violet. Red is at the top of the rainbow when listed in the order in which they appear in a natural rainbow.

The name "Marisol" is a combination of "mar" (Spanish for sea) and "sol" (Spanish for sun), representing two quintessential elements of summer: the sea and the sun.

Far as scientific research goes, radio carbon dating eruption of El Misti back to 7190 BC ± 150 years.

It is to note: many thing in nature exist before human start recording the history. Volcanic eruption is one of them. El Misti might have been erupt before the 7190 BC but the 7190 BC is the earliest that scientist found the evidence.

one problem is weight gain or loss because of micro gravity and your body is no longer working hard to keep your self upright also bone loss if you stay for long periods of time in space because the micro gravity minimizes the need for bones or supports at all.

You can feel it; you cannot see it.

There is a short beautiful poem discussing this very question:

Who has seen the wind?

Neither you nor I,

But when the trees bow down their heads the

Wind is passing by.

l love the above poem. it is delight ful. a wish to add bit more

air is life, breathe in, inhale full lung to feel strength, exhale..life less i mean .....experiencer is un seen to experience....i heard the state of hyperventilation syndrome is experienced the state of nothing ness..

MY ANSWER IS....SPECTROSCOPE....because stars can seen through spectroscope...:))

sorry kung ganito lang kasimple yung answer ko...im just a grade 6 pupil lang kasi..

nice to meet you all...

-Dulce Dumapias...add me on facebook..ahaha:)) see you there..:))

The Prime Meridian is located at 0 degrees longitude and runs through the Royal Observatory in Greenwich, London, UK. It serves as the starting point for measuring longitude and divides the Earth into Eastern and Western Hemispheres.

Daily life example of rotation can bee seen in various objects such as in opening and closing of the door. When we open or close a door, the plywood or door is rotated on its axis that is on the hinges to which it attached.

Rovers on Mars can stay on the surface due to the red planet's gravitational pull. While gravity on Mars is only about 38% of that on Earth, it is still strong enough to keep objects on its surface. Rovers are designed with wheels and traction systems to navigate and maneuver across the Martian terrain.

Changes can affect particles by altering their behavior, arrangement, or properties. For example, changes in temperature can cause particles to move faster or slower, while changes in pressure can affect the density and arrangement of particles. Additionally, changes in chemical composition can lead to the formation of new particles or the dissolution of existing ones.

The magnification of van Leeuwenhoek first microscope depends on what one considers his "first" microscope.

Over a period of nearly 50 years, Anton van Leeuwenhoek made over 500 optical lenses (though they were used in an estimated 200 different microscopes) and can be said to have constructed at least 25 variations on the basic design of the microscope. Nine of his microscopes still exist.

The lenses he made improved over time and would have started out at the low power of 5x or 10x typical for the time. When he made his discovery of how to make small spherical lenses, there would have been a significant jump in magnification to what power one can only guess, but it was larger than the best compound microscopes of the time which was around 30x. They continued to improve for the next 20 years.

Of the lenses that he made which still remain, one is a 256x power lens. It is guessed, based on the quality of his reported observations, that he may have produced lenses with twice that magnification.

Sound requires a medium, such as air, water, or solid surfaces, to travel through. In outer space, there is no medium for sound waves to travel through, so sound cannot propagate in the vacuum of space.

The nucleus of an elodea cell is suspended in the cytoplasm within the cell wall. When the plant cell is well hydrated, the central vacuole swells with water and pushes the nucleus and chloroplasts toward the outer edge of the cell. In a poorly hydrated cell, the nucleus may be located any where within the cell.

Astronauts conduct experiments, maintain the spacecraft, exercise regularly to combat muscle loss, perform spacewalks to repair and upgrade equipment outside the spacecraft, communicate with mission control, and take part in educational outreach activities.

The second space shuttle was named "Challenger." It followed the first space shuttle, Columbia, in NASA's fleet of reusable spacecraft. Challenger tragically disintegrated shortly after launch in 1986.

Scientific explanations of natural phenomena are based on empirical evidence, logical reasoning, and testable hypotheses. Scientists use the scientific method to formulate and test hypotheses, collect data through observation and experimentation, and draw conclusions that can be replicated and validated by others in the scientific community. They also rely on established theories and principles to explain the underlying mechanisms behind natural phenomena.

I uderstand the cardinal directions to be North, East, South and West

The southern pole star is called Sigma Octantis. It is located very close to the southern celestial pole and serves as a guide for navigation in the Southern Hemisphere, much like Polaris does for the Northern Hemisphere.

Careful observation involves paying close attention to details, patterns, and changes in a certain subject or situation. It often requires patience, focus, and recording of observations to gather accurate information and insights.

Scientists predict that the universe will continue to expand forever based on observations of the universe's current rate of expansion, known as the Hubble constant, and measurements of the universe's overall density. These observations suggest that the expansion is accelerating, driven by a mysterious force called dark energy, which counters the effects of gravity and pushes galaxies further apart.
