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.
What is the significance of the animals and plants?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.

What happened as the mass of the sun increased during the formation of the solar system?
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.
What is the 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.

Both species benefit in the type of symbiosis called parasitism. Please select the best answer from the choices provided T F
The statement “both species benefit in the type of symbiosis called parasitism” is false.
Parasitism is a type of symbiosis where one organism is harmed while the other benefits.
An example of parasitism is a dog infested with ticks.
The ticks benefit from drinking the dog’s blood, harming the dog in the process.

What is the effect is a beam of light hits a green leaf?
When light strikes a green leaf, most of the green spectrum is reflected and most of the other colors are absorbed.
what is light?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.
What is reflection?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.

Which statement explains why hydrogen bonds are able to form between water molecules?
Water molecules are polar.
Water molecule atoms have weak atomic bonds..
Water molecules show adhesion.
Water molecules are large.
Answer:
Water molecules are polar.
Explanation:
Hydrogen Bonds - Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.
This bond is very weak. Hydrogen bonds are formed easily when two water molecules come close together, but are easily broken when the water molecules move apart again. They are only a small fraction of the strength of a covalent bond, but, there are a lot of them
The fact that water molecules are POLAR makes it possible for hydrogen bonds to form between them.
HOW IS WATER POLAR?
Water is a chemical compound made up of two hydrogen atoms and one oxygen atom i.e. H2O. The hydrogen atoms are electropositive while the oxygen atom is electronegative. The electronegativity of the oxygen atom allows the positive hydrogen ions to be attracted towards it. This makes water molecules polar. Hydrogen bonds form when hydrogen ions (H+) are attracted to an electronegative ion like 02-, S2- etc. Hence, in the interaction of water molecules, the hydrogen ion of one water molecule gets attracted to the oxygen ion of another water molecule, hence, forming HYDROGEN BOND.In a nutshell, hydrogen bonding is possible in water due to its polariry.

Pls help due soon: Why is the moisture of cirrus clouds mostly in the solid state?
The moisture of cirrus clouds mostly in the solid state as the higher altitude allows for lower temperatures, leading to frozen water crystals. The correct option is A.
What are cirrus clouds?These clouds indicate that the weather is favorable. They are distinguished by their high altitudes, which reflect the direction of the wind, which moves them and constantly changes their shapes.
The higher they are, the lower the temperatures; son water vapor condenses into crystals, which are blown in different directions by the wind.
Cloud formation occurs when humid air ascends and experiences adiabatic cooling due to the high temperature.
Because the density and pressure of the air decrease as altitude increases, the air tends to expand with elevation in response to the reduced pressure.
Gases in expansion experience adiabatic cooling, losing caloric energy as their molecules move further apart. As the air rises, it becomes colder and thus denser.
Thus, the correct option is A.
