fossils are the remains of the living organisms that existed a long time ago. They are well preseerved by nature and are vital for us as they enable us to know about the living conditions in which they existed. They tell us about the phases of evoultions through which they must have undergone in order to sustain themselves in the competetive environment. The fossils can tell us about the species's evolution and its adaption towards the environmental condition and thus help us in understanding the natural selection easily. natural selection is the theory given by Darwin about the evolution of species.fossils are the remains of the living organisms that existed a long time ago.

You can usually find Fisheries Science O level past papers on educational websites, bookstores, or online platforms that offer educational resources. Contacting your school or educational institution's examination office may also be helpful in obtaining past papers.

Blinking helps to spread tears evenly over the surface of the eye, keeping it moist and preventing dryness. It also helps to clear debris and dust particles from the surface of the eye, reducing the risk of irritation and infection. Additionally, blinking helps to reset and rejuvenate the eyes, providing a quick break from staring at screens or other objects for prolonged periods.

Volume is measured in cubic metres, because the unit is cubed it means that the normal prefixes can be confusing; there are 100 cm in 1 m, but 1 000 000 cm3 in 1 m3. This means that the non-SI unit of the litre is used in most cases. 1 m3 is 1000 litres.

Voyager 1 and 2 were launched by the USA in 1977 and after 34 years are still sending back valuable information. Their mission is now to explore interstellar space and should be beyond the influence of the sun in a few more years.

Increased pulse rate means faster blood, and when blood goes from a vessel with a larger diameter to a smaller ones such as capilaries, it naturally speeds up. It would speed up more and depending on the vessel's wall resistance, might rupture the capilary.

Contrails are the white, cloudlike trails left behind jets flying in the sky. They form when water vapor, a byproduct of the combustion taking place in the jet engines, condenses into water droplets (or ice crystals, if the temperature is low enough) after it has cooled down from the colder temperature high in the sky. This is similar to how clouds form.

In space, there is no atmosphere, so there is no air to breathe or sound to carry. Objects in space experience microgravity, causing them to float. Space is also extremely cold and exposed to radiation from the sun and other cosmic sources. Astronauts need special suits and equipment to survive in space.

The effect is called "atmospheric refraction." It occurs when light rays passing through air at different temperatures are bent, causing objects to appear shifted from their actual position. This is why stars and the Sun can appear slightly higher in the sky than they actually are when near the horizon.

If Earth were farther from the sun, its year would be longer because it would take more time for the planet to complete one orbit. This would result in longer seasons and potentially colder temperatures overall.

Originally they were used to grip food with your mouth,

but in humans they are just used to chew.

My choice of a 3 syllable word to describe science is objective.

Time does not go quicker in space, but it can appear to be faster in certain circumstances due to time dilation effects predicted by the theory of general relativity. Near a massive object like a black hole, time can appear to pass more slowly compared to an observer in a different gravitational field, leading to the perception of faster time passage.

The largest living single organisms are the giant sequoia of the plant kingdom. Creatures, however, are generally considered animals, of the Animal Kingdom. Both plants and animals are metazoans, in the "Kingdom of Eukaryotes."

Scientists such as Isaac Newton and Albert Einstein successfully explained the observations of the physical world through their groundbreaking theories of physics. Newton's laws of motion and universal gravitation, as well as Einstein's theory of relativity, helped to provide comprehensive explanations for a wide range of phenomena in the universe.

Materials such as aluminum, titanium, carbon composites, and other lightweight yet durable metals are commonly used in spacecraft construction. These materials need to withstand the extreme conditions of space, including temperature variations, radiation, and vacuum. Additionally, specialized components such as solar panels, heat shields, and advanced electronics are necessary for a spacecraft to function properly.

The photo receptors that enable us to see in dimly lit conditions are called rods. Rods are highly sensitive to light and are responsible for detecting low levels of light, allowing us to see in dim lighting situations.

The sensory layer in the back of the eye is called the retina. It contains cells that are sensitive to light and is responsible for capturing visual images that are sent to the brain via the optic nerve for processing.

You could use a dynamic model that considers the aerodynamic forces acting on a bird in flight, such as an ornithopter model that simulates the flapping motion of bird wings. You could also use a computational fluid dynamics (CFD) model to study the airflow around bird wings during flight.

The scientific name for fear of heights is acrophobia.

pathway that a celestial body follows. Planets, comets, asteroids orbit the Sun. Moons orbit their planets. The Solar System orbits the Galactic Center.
It is the imaginary pathway that a body in space follows as it moves around another body. The earth and the other planets orbit the sun, and various moons orbit their host planets.

A malacologist studies mollusks, which include animals like snails, slugs, clams, and octopuses. They research various aspects of mollusks such as their biology, ecology, behavior, and diversity.

Gravity causes all orbits. It is believed that there is a "super massive" black hole at the center of the Milky Way, and most or all other galaxies, that serves as the primary source of gravity.

We see object from the light they either produce or reflect. The Sun gives off light waves. An object absorbs all colors but what you see. The reflected light then travels to your eyes where it is interpreted.

The tube that leads to the bladder is called the ureter.
