Hello!
Red stars have a larger radius and luminosity than a main sequence (aka dwarf) star of the same surface temperature.
Many fruits contain specialized structures that are adaptations for The answer is D. aiding in seed dispersal.
Maple trees have fruits with "Wings" that help the gale disperse the seeds. Some flowering plants grow fleshy fruit that benefits disperse their seeds. When animals eat the fruit, the seeds pass through an animal's digestive tract undamaged.
<h3><u>Answer</u>;</h3>
- The amount increases as the object is lifted higher
- The amount varies according to the mass of the object
<h3><u>Explanation</u>;</h3>
- Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
- The equation for gravitational potential energy is mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
- <em><u>The factors that affect an object's gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in</u></em>.
If you do not perceive a color change, or the emission of light or heat, it is still possible a chemical reaction has taken place.
A chemical change involves a change in the composition of a substance. It leads to the rearrangement of atoms and formation of a new substance.
Some cues may help us to know when a chemical change has taken place such as;
- Change in color
- Formation of a solid
- Evolution of heat
- Evolution of a gas
It is possible for a chemical change to occur without noticing these cues. For instance, two colorless solutions may react with each other and the product of the reaction remains colorless.
In this case, there is no physical cue signifying that a chemical change has taken place even though it actually happened.

The two types are Alcoholic fermentation and lactic acid fermentation.
