Answer: There are two types of change in matter: physical change and chemical change.
Explanation:
As the names suggest, physical changes never change the identity of the matter, only its size, shape or state. In a physical change, atoms are not rearranged and the matter's physical and chemical properties are unchanged.
to learn more about matter and how it changes take a look at this website:

Deshawn is conducting an experiment about fermentation. He prepares six bottles. The table shows what he puts in each bottle.
bottle 1 1 cup cold water, 1 packet yeast
bottle 2 1 cup cold water, 1 packet yeast, 2 tablespoons sugar
bottle 3 1 cup lukewarm water, 1 packet yeast
bottle 4 1 cup lukewarm water, 1 packet yeast, 2 tablespoons sugar
bottle 5 1 cup hot water, 1 packet yeast
bottle 6 1 cup hot water, 1 packet yeast, 2 tablespoons sugar
He swirls the bottles until the yeast dissolves and puts a balloon over the neck of each bottle. In 20 minutes, he will check and see what has happened.
6 bottles with balloons stretched over the mouths, balloons are not inflated

List the muscular organs in the muscular system (nothing to do with other organ systems).
HOMEWORK DUE TOMMOROW!
Answer:
A whole skeletal muscle classifies as an organ of the muscular system. Each organ or muscle has skeletal muscle tissue, nerve tissue, blood or vascular tissue, and connective tissue.
The different organs in the muscular system include cardiac muscles, smooth muscles, skeletal muscles, connective tissue, nerve tissue and blood tissue Rhythmic contractions cover the heart’s wall. It is responsible for the beating of the heart. The skeletal system allows the body to extend and contract.

The diagram shows one way that genetic information can be passed from a parent to an offspring.
--
Which statement names and best describes the process in the diagram?
A) Meiosis; occurs during asexual reproduction and will not result in genetic variation among the offspring.
B) Meiosis; occurs before sexual reproduction and will result in offspring with different genetic information from the parent.
C) Mitosis; occurs during asexual reproduction and will not result in offspring with different genetic information from the parent.
D) Mitosis; occurs before sexual reproduction and will result in genetic variation among the offspring.
Victoria and her teacher measured a sample of matter in the science lab. They measured the sample using all of the tools below to make sure the results were correct.
Each time they measured the sample, its shape changed to match the shape of the container. The amount of the sample always equaled 400 mL.
What type of matter did Victoria and her teacher measure?
A. gas
B. liquid
C. solid
Answer:
The answer is liquid
Explanation:
Because liquid is a type of matter that does not have a definitive shape, so it relies on taking its shape from the substances that it settles in.
In this example, the amount of liquid used was 400mL, when they poured liquid in, it took the shape of the container.
While gas can get a shape of a container, its volume is not fixed.
Answer: Your correct the answer is liquid
