Answer:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula.
Explanation:
Answer:
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. In a chemical change, the kind of matter changes, and at least one new substance with new properties is formed.
Explanation:
Physical changes are limited to changes that result in a difference in the display without changing the composition.

In addition to the frog, the other organisms that are classified as modern amphibians are toads and salamanders. Therefore, the correct option is A.
What are modern amphibians?Modern amphibians are a class of cold-blooded vertebrates that spend part of their life cycle in water and part on land. They are united under the taxon Lissamphibia. They are divided into three clades which are Urodela, Anura and Apoda. In addition to frogs, the other two groups of modern amphibians are toads and salamanders.
Snakes and lizards are reptiles, which are a different class of cold-blooded vertebrates. Opossums and koalas are marsupials, which are warm-blooded mammals, and sharks and skates are fish, which are cold-blooded vertebrates but are not classified as amphibians. Therefore, the correct option is A.

7. Explain the following: All compounds are substances,
but not all substances are compounds."
Answer:
Below
Explanation:
"All compounds are substances, but not all substances are compounds."
In simpler terms, let us use an example. Look at the image below.
In a big circle, there are substances. And in the small there are compounds. Since the compounds are inside the big circle, they are compounds, but as you can see, the substances are not inside the compounds so they cannot be considered compounds.
If you think about it, a substance is anything. So would you think a bottle, for instance, is a compound? A compound is a mixture of molecules. And a substance is most likely a combination of atoms, which are elements.
are genes for green seeds similar to yellow genes? Explain your answer.
Answer:
Explanation:
There is no “yellow” gene in the peas found on farms. ... Mendel's experiments showed that green is the recessive seed color in pea plants.
Since yellow is dominant to green, all of the offspring were yellow.

When the concentration of ________ in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.
When the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.
OSMOSIS:
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane. Osmotic principle is based on concentration gradient i.e. difference in concentration across a membrane. Electrolytes represent solute such as salts, ions, sugar etc. Therefore, when the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.Learn more at: https://brainly.com/question/2404589?referrer=searchResults
how does an autoimmune disease affect the muscular system?
Answer:
Explanation:
Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body's own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.

Explanation:
The quick trick is that osmosis can only occur in water or insolvent movements!
Think of fish, fish have a lot to do with osmosis because the water will go through the fish's skin/gills which will help them breathe and thrive.
!! hope that helps love you guys !!
The movement of water across cellular membranes through aquaporins is known as osmosis. Water moves down the concentration gradient. The fourth option is the correct answer.
How do molecules move across the cell membrane?Molecules can pass the cell membrane both actively and passively. In passive transport, no energy or ATP is required. Molecules can move from a higher concentration to a lower concentration.
Diffusion and osmosis are examples of passive transports. In diffusion, gases and other small molecules pass the cell membrane from a higher to a lower concentration. Water is a polar molecule, so it doesn't pass the membrane due to its nonpolar nature. Cells have aquaporin channels that are made for water.
Through aquaporins, water passes into the cell. This is called osmosis. In active transport, energy is required. When a molecule passes from a lower concentration to a higher concentration, energy is needed. An example is sodium-potassium ATPase.
Hence, the correct answer is osmosis. The fourth option is the correct answer.

Which of the following is NOT an accessory gland of the male reproductive system?
Answer:
a. Testosterone gland
Explanation:post protected
Testosterone gland is not an accessory gland of the male reproductive system.
What is Testosterone gland?Testosterone is a hormone that is primarily produced in the testicles in males and in small amounts in the ovaries and adrenal glands in females. It is a vital hormone that plays a critical role in the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass, bone density, and body hair growth.
Testosterone is also essential for maintaining sex drive and overall physical health in both men and women. The production of testosterone is regulated by the hypothalamus and pituitary gland in the brain, which release signals to the testes to produce testosterone.
Certain medical conditions, lifestyle factors, and aging can affect testosterone production and levels, which can have significant impacts on health and wellbeing. Treatment options are available to address testosterone deficiencies and imbalances.
