Answer:

D. Sound waves can move through a vacuum.

Explanation:

Sound waves can move through a vacuum is an incorrect statement.  

• Sound is a kind of energy produced by vibrations. These vibrations generate sound waves that move via the mediums like water, air, and wood.  

• The sound waves are not visible as it is a form of energy, sound waves generate movement in the object, which continues till the particles run out of energy.  

• A sound wave mediates its energy through particle interaction, and a sound wave cannot travel via a vacuum, this shows that sound is a mechanical wave.  

Thus, sound waves cannot move through a vacuum. Option A is not true.

When light strikes a green leaf, most of the green spectrum is reflected and most of the other colors are absorbed.

We can see light as a sort of energy. The sun provides some illumination. The other light is artificial. Man-made light is created by converting another type of energy, such as electricity, into light energy. From a source, light travels in a wavy beam to whatever it encounters. Each hue is represented by a tiny wavy beam on the beam. A light beam travelling through the air that contains all of the hues appears to be clear.

When a light beam strikes an object, such as tree leaves or an apple, the color of the object influences the smaller color beams inside the light beam. All color rays except green are absorbed by the green leaves. Only the green beam is reflected back, thus the leaves appear green to our eyes. Except for red, the apple absorbs all color beams. Only the red beam is reflected back, thus the apple appears red to human eyes. This is referred to as reflection.

Answer: C. Are made up of one or more cells

Explanation: Good luck! :D

A chimpanzee and a pine tree have very little in common because they are both living things, and made up of one or more cells that is the first and third option, as they are both living forms of nature, and while the chimp is movable, the pine tree is not.

The significance of animals and plants is that both have unique characteristics and equal importance in nature, such as the plants' ability to produce food through the process of photosynthesis and the animals' ability to keep the system clean, such as when some animals help in plant fertilization, maintain the carbon and oxygen cycles, and so on.

Hence, a chimpanzee and a pine tree have very little in common because they are both living things, and made up of one or more cells that is the first and third option, as they are both living forms of nature, and while the chimp is movable, the pine tree is not.

The transport of specific particles down their concentration gradient through a membrane by carrier proteins is known as facilitated diffusion. ... Facilitated diffusion moves molecules and ions against their concentration gradient, while active transport moves molecules and ions down their concentration gradient.

Answer:

The Sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust called a solar nebula about 4.5 billion years ago. Most of the material was pulled toward the center to form our Sun, which accounts for 99.8% of the mass of the entire solar system.

The increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system.

As the mass of the sun increased during the formation of the solar system, several important changes occurred. One of the most significant changes was the increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system. As a result, the temperature and pressure at the center increased, eventually reaching a point where nuclear fusion began and the sun became a star.

The increase in mass also had an impact on the orbits of the planets. As the gravitational force of the sun increased, it caused the orbits of the planets to become more stable and circular, rather than elliptical or irregular. This stability allowed the planets to maintain their orbits over billions of years, contributing to the long-term stability of the solar system.

In addition, the increase in mass allowed the sun to retain more of the lighter elements, such as hydrogen and helium, which were abundant in the early solar system. This abundance of lighter elements contributed to the formation of the gas giant planets, such as Jupiter and Saturn, which have massive hydrogen and helium atmospheres.
