d. make sugars for energy.
and chemical changes as they cook.
One of the ingredients for her main course undergoes physical changes. Which of the
following is a physical change?
boiling water
cooking eggs
O grilling hamburgers
O baking bread
Boiling water is an example of physical change as it does not cause any change in the chemical composition of water.
Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

Answer:
Boiling water
Explanation:
A reference to the Sun! The chemical reaction that results from the energy of light leads the molecules of water and carbon dioxide to disintegrate and then reassemble into molecules of glucose and oxygen gas. After the sugar is created, the mitochondria convert it into energy that can be used for growth and repair. Thus, option B is correct.
Water and carbon dioxide are converted by plants into a sugar called glucose using the power of the sun. Glucose is used by plants as a fuel source and to make substances like cellulose and starch.
Cellulose is used to build cell walls. Starch is preserved in seeds and other plant parts for use as a food source.
Therefore, The sun provides the plants with the energy they need to develop and prosper. The plants would not be able to survive if it were always dark outside.

Answer:
Some differences between primary and secondary succession are:
-Secondary succession happens on a previously existing community that has been cleared.
Another difference would be:
-Pioneer species for secondary succession are adapted differently- they grow quickly, can disperse quickly and have a short life span
And finally:
-Primary succession develops a new community from scratch
