Answers

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...

Answers

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 protein

Furthermore, 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.

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.)

Answers

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.

A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.[1] Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected greatly for its chemical properties to be investigated. When a substance goes under a chemical reaction, the properties will change drastically, resulting in chemical change.


Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

75% straight roots and 50% bent roots. sorry bb i’m not good at explaining why, but i promise it’s correct! <3

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.

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.
