Adding and removing energy can change the physical properties of a substance.
A) true
B) false
Answer: True.
Explanation: Energy is being removed from the substance as it changes state. As energy is added to the liquid, particles throughout the liquid move faster. Boiling. When particles move fast enough to break away from other particles, they evaporate and become gas.

What is Carbon cycle?
Carbon cycle is describes as the process in which carbon atoms travel from the atmosphere to the Earth and return back into the atmosphere. This cycle is important for maintaining a stable climate and carbon balance on the planet.
Carbon cycle affect the net amount of carbon in the atmosphere at given period of time and the rate of carbon exchange between different reservoirs on the Earth’s surface. Carbon modulates the climate change by the regulation of atmospheric CO[tex]_2[/tex] which represents one of the most important ecosystem services of value to human.

Answer:
adhesion
Explanation:
The term used to describe the attraction of water molecules to other molecules is referred to as adhesion.
Generally, adhesion or adhesive forces is a term used to describe the force of attraction between molecules of different substances. This is as opposed to cohesion or cohesive forces which refers to the force of attraction between the molecules of the same substance.
Hence, when molecules of water attract or stick to other molecules, the force at play is an adhesive force or simply adhesion.

Which of the following is TRUE about the polarity of water?
(1 Point)
only H atoms have electrons
electrons are more strongly attracted to the H atom
electrons are more strongly attracted to
the O atom
electrons are shared equally between all atoms within the molecule
Answer:
electrons are more strongly attracted to the O atom
Explanation:
It is true that in the in the polarity of water, electrons are more strongly attracted to the oxygen atom compared to the hydrogen atom.
In a water molecule, there are two atoms, hydrogen and oxygen. These atoms are bonded together by covalent bonding. Oxygen is more electronegative compared to Hydrogen. It pulls the shared electron more itself compared to hydrogen. This leaves a net negative charge on the oxygen and net positive charge on the hydrogen. The charge separation makes water polar.The properties of a substance are not affected by chemical reactions.
A) true
B) false
Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Explanation:
The statement "the properties of a substance are not affected by chemical reactions" is false.
What are physical and chemical properties?A substance's physical property is a quality that can be seen or quantified without affecting the substance's identity. Color, density, hardness, and melting and boiling points are examples of physical qualities.
A quality of matter that is unrelated to a change in its chemical makeup is called a physical property. Density, color, hardness, melting and boiling points and electrical conductivity are a few common examples of physical qualities.
Chemical changes result in new compounds with different properties from the original ones, as well as new particles and maybe altered particle numbers.
Therefore, the statement is false.

Transcription copies DNA into RNA. Messenger RNA is transcribed DNA that encodes proteins. Therefore, a new mRNA strand is synthesized here and the process is transcription.
What is transcription?The act of producing a copy of the genetic information that is contained in a strand of DNA and converting it into a complementary strand of RNA (also known as messenger RNA or mRNA) with the assistance of RNA polymerases is referred to as transcription. This process is carried out in the cytoplasm of prokaryotic cells. This process takes place within the nucleus of eukaryotic cells.
There are three stages that make up the process of transcription: initiation, elongation, and termination.

If a fault is currently locked, it is not moving. True O False
Answer:
if it is not slipping, then no
Explanation:
A locked fault is a fault that is not slipping because frictional resistance on the fault is greater than the shear stress across the fault (it is stuck). Such faults may store strain for extended periods that is eventually released in an earthquake when frictional resistance is overcome. Have a great day! :)
Which activity uses ATP to raise body temperature?
shivering
storing fats
panting
hibernating
Answer:
shivering it creates energy, 60% of which is wasted on heat
Shivering uses ATP to raise body temperature. So the correct option is A.
What is shivering?Without your conscious involvement, your body controls how it reacts to stress, illness, heat, cold, and other situations. When you are too hot, for instance, you sweat to cool the body, but you don't have to think about it. And you shiver naturally when you're chilly.
Your muscles quickly contract and release, which results in a shudder. Your body naturally tries to warm up as it becomes cooler, which is why you are experiencing this uncontrollable muscular activity.
The only reason you shiver, though, is in response to the cold. You may tremble and shiver due to a variety of factors, including illness. You could start to shiver as the temperature falls below what your body considers comfortable. Your body's surface heat production might increase by around 500% when you can see yourself shivering. However, shivering will only temporarily warm you up.
Your muscles will eventually run out of glucose (sugar) to use as fuel and become too exhausted to contract and relax after a few hours. The temperature during which shivering begins varies depending on the individual. Children, for instance, may shiver more readily in reaction to higher temperatures than an adult with greater body fat would.
Therefore the correct option is A.

Answer:
Convert solar energy to chemical energy stored in sugar
Explanation:
Photosynthesis is the process whereby green plants manufacture their food, which is in the form of a sugar (glucose). The photosynthetic process, generally, combines carbon dioxide (CO2) and water (H2O) in the presence of sunlight, which provides energy used.
The sugar (glucose) produced stores chemical energy in its chemical bonds. In a nutshell, photosynthesis converts SOLAR ENERGY (from sun) into CHEMICAL ENERGY (in glucose), which is the purpose of the process for organisms that undergo it.

Which explanation accurately describes how matter is transformed within the process of photosynthesis?
A) In the light reactions, carbohydrates release hydrogen atoms and form carbon dioxide. The hydrogen atoms join with oxygen to form water molecules in the Calvin cycle.
B) In the Calvin cycle, carbohydrates release hydrogen atoms and form carbon dioxide. The hydrogen atoms join with oxygen to form water molecules in the light reactions.
C) The hydrogen and oxygen atoms of water are split in the Calvin cycle, and oxygen is released. In the light reactions, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Answer:
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Explanation:
Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.
Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.
Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
