2.Physical change; Physical property of flammability
3.Chemical change; Physical property of heat of combustion
4.Chemical change; Chemical property of heat of combustion
Answer:
Answer: Chemical change; Chemical property of heat of combustion
Explanation:
A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.
Explanation:
Answer:
: Chemical change; Chemical property of heat of combustion
Explanation:
A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.
Example: Melting of ice
Physical property is defined as the property of a substance which becomes evident during physical changes. Example: Melting point
A chemical change is defined as a change in which a change in chemical composition takes place. A new substance is formed in these reactions.
Example: combustion
Chemical property is defined as the property of a substance which becomes evident during chemical changes. Example: Reactivity with other substances
Thus when a piece of coal and a piece of wood is burnt , there is formation of new substances and thus is a chemical change. Combustion is a chemical property as it is reactivity of a substance with oxygen.

Answer:
75% straight
50% bent
Explanation:
because the Punnett Squares work that way
think of it as a multiplication table...when 2 numbers come to the middle, they give you the answer just like these squares (they're just smaller)
R + R = RR
R + r = Rr
R + r = Rr
r + r = rr
RR is 25%
Rr is 50% because there are 4 boxes and 2 of them is Rr
rr is 25%
Simpler answer:
I know because 25% + 50% = 75% for the straight root. 25% + 25% = 50% for the bent toot.

Explain the correlation between chemical properties and chemical changes. (plz i not sure on the answer so it would mean a lot if you could help me.)
Answer:
Explanation:
A chemical property describes the ability of a substance to undergo a specific chemical change.
A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.
Differences
Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.
Physical properties are properties that can be observed without bringing a chemical change.
Another one
chemical properties; can be used to predict how substances react.
chemical changes; It is mostly used in identifying or describing the substance.

photosynthesis occurs and extra food is stored in which plant tissue\
dermal

ground
don't just do for points or i will report and whoever answer get's brainliest
Answer:Ground
Explanation:The roots help soak up moisture fromthe ground and can also store extra food made from photosynthesis
Photosynthesis occurs and extra food is stored in ground plant tissues in the form of sugars.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.What does she need from the food she ate and the air she breathes so that she can go on her run? (Sentence starter: The molecules Rosa needs from the food she eats and air she breathes are...
Answer: What does she need from the food she ate and the air she breathes so that she can go on her run?
A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).
B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.
How do Rosa's body systems work together to get the molecules she needs into her cells?
Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).
How do hair cells use these molecules to release energy for her body to run?
The substrates (glucose and oxygen) enters the bloodstream and then taken up to the cell. Then they are provided to the mitochondria for the release of energy in the form of ATP. This is why mitochondria are known as the powerhouse of the cells. Within the cell, energy is released in a three-step process, i.e. glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. In the end, aerobic respiration per reaction run produces 36 molecules of ATP which are sufficient to meet intensive energy needs. During excrcise, the supply of oxygen and glucose is also faster due to faster lungs and heart actions.
PS: Anaerobic respiration cannot meet energy demands faster because the reaction produces only 2 ATP molecules per reaction run.
Explanation:
The molecules Rosa needs from the food she eats and air she breathes are
Food which are rich in carbohydrate to help her jog. This is because she is on a weight loss program which needs her to avoid proteinFurthermore, she would need oxygen so that she can successfully have aerobic respiration where there would be maximum release of energy to enable her complete her run better
According to the given question, we can see that Rosa wants to lose weight and she takes peanut butter which she takes and she is breathing normally which helps her perform aerobic respiration.
As a result of this, we can see that there is a need for Rosa to have the right diet which would help her with her jogging and weight loss program.
This would need foods that are rich in carbohydrate which would enable her to lose weight better and oxygen so that she could be efficient with her jogging and burn fat.

Answer:
conduction is the transfer of heat between two objects that are next to each other and in direct physical contact, or touching . It is caused by a temperature difference between the objects. Conduction is one way that heat is transferred from Earth's surface to air. In nature, heat always moves from a warmer object to a cooler object. When air molecules touch the warm ground or water on the surface, heat is conducted from the ground or water to the air molecules, heating them up.
