Which of these statements is true of using melting and boiling points to identify a substance? Text to speech A:A. It is an effective method to identify gas molecules. B:B. It is the most affordable way to identify a substance. C:C. It is a property that changes based on the amount of a substance you have. D:D. It is a property that does not change regardless of the amount of a substance you have.
Answer:
D:D. It is a property that does not change regardless of the amount of a substance you have.
Explanation:
Melting and boiling points are two chemical properties of a substance. These are used to identify whether a substance is solid, liquid, or gas.
The melting point is the temperature at which solid-state changes into liquid state. The boiling point is defined as the temperature at which liquid changes to gas.
The melting and boiling point are intensive properties that are independent of the amount of substance to be identified.
Hence, the correct answer is "D. It is a property that does not change regardless of the amount of a substance you have."

The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. Why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. The available energy from one trophic level to another increases b. Energy is lost at each level as heat, which increases randomization c. The amount of biomass decreases from one trophic level to another d. The available energy at each level may either increase or decrease, creating randomization.
The quantity of entropy in a food chain differs among trophic tiers the best choice is "B" strength is misplaced at every degree as heat, which will increase randomization.
The amount of entropy is the energy required for the movement from one trophic level to another and when strength is misplaced at every degree as heat, which will increase randomization then the amount of entropy increase from one trophic level to another in a food chain or energy pyramid.
What are the ten in line with the cent regulation of strength?
The 10% Rule shows that after strength is flowing in surroundings from one trophic level to the next, the best ten in line with cent of the strength could be exceeded. The trophic level is the placement of an organism in a food chain or strength pyramid.
Thus, strength is misplaced at every degree as heat, which will increase randomization.

7. This tortoise is eating cactus on a sunny day. Is carbon moving into the air, moving out of the air, or both? a Carbon is not moving into the air; it is only moving out of the air. B With this information, there is no way to know for sure. C Carbon is only moving into the air; it is not moving out of the air. D Carbon is moving into the air and out of the air at the same time.
Answer:
Id say that carbon is moving into the air, since the turtle is inhaling oxygen and exhaling carbon dioxide.
Explanation:
Carbon is moving into the air and out of the air at the same time. So, the correct option is D.
What is the Carbon cycle?The exchange of carbon between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth is called as the carbon cycle. Most biological compounds and many minerals, like limestone, primarily comprise carbon.
The carbon cycle explains how an ecosystem's both biotic and abiotic constituents interchange this element. For biological systems to survive in the natural world, the carbon cycle is essential. Carbon is moving into the air and out of the air at the same time in the given example by the Tortoise. Carbon cycle consists of four phases into Photosynthesis, Decomposition, Respiration and Combustion
Therefore, the correct option is D.

All cells are surrounded by a cell membrane. Which statement is NOT an accurate description of a cell membrane? a Regulates what enters and leaves the cell. b Responsible for the formation of ATP c Provides protection and support for the cell. d Flexible and made up of smaller molecules such as lipids and proteins
Answer:
The correct answer is - b. Responsible for the formation of ATP
Explanation:
The cell membrane is the outer membrane of all types of the cell including eukaryotic, and prokaryotic cell. The cell membrane surrounds the cytoplasm and cell organelles.
The cell membrane is made up of phospholipids that have a hydrophilic and hydrophobic region in the lipid bilayer. The main function of the cell membrane is to protect the cell, provide support, and regulation what enters and leaves the cell. ATP formation is not produced by the cell membrane.

Mendel bred an unknown plant displaying a dominant phenotype with an individual showing the recessive phenotype; then, he analyzed the offspring to determine the unknown genotype. This experiment is called a(n)
What Mendel did according to the illustration would be called test-crossing.
Test-crossingIn genetics, test crossing is a procedure through which the zygosity of an individual can be determined - whether it is homzygous or heterozygous.
Test crossing requires that an organism who displays a dominant trait but whose zygosity is unknown is crossed with another organism of the same species but who displays the recessive version of the same trait.
By so doing and using the knowledge of probability, the resulting offspring from the cross will be used to determine the zygosity level of the parent.

Answer:
No, this is because the work itself of creating/constructing new developments may cause danger to the society. This may also cause environment issues and pollution in the air and many animals may be harmed. Also, by removing trees for developments, this may decrease the amount of oxygen and nature in the area.
