Answer:

The correct answer would be "it would decrease the transpiration pull".

Transpiration pull is a type of suction force by which water is being pulled from the roots to reach the leaves.

The cohesion force between the molecules of water help in keeping the water molecules together which also aids in maintaining the suction pull.

Formation of the air pocket in any part of the xylem would decrease the intensity of transpiration pull.

Thus, it would decrease the efficiency of the plant in pulling water and minerals from the roots.

The vascular system of the plants are responsible for transporting water and needed nutrients for the plant to survive. Hence, when this is disturb certain transpirational pull is also disrupted, rendering the plant unable to collect water effectively. Thank you for your question.

Water Cycle 1. How is water stored on Earth during the water cycle? 2. Water moves into the atmosphere through ____________ and
Naily [24]
Water Cycle:


1. It is stored in the ground.

2. Evaporation, transportation, precipitation

3. Runoff comes straight from precipitation. Infiltration is from the ground while run off never went in the ground.

4. It will usually end up in the same place, the ocean

5. Water levels rise, temperatures rise, CO2 in atmosphere increases


Carbon Cycle:

1. Carbon is important because it is one of the basic building blocks of life.

2. Trees, animals, grass, decomposition, combustion, fossil fuels

3. Carbon enters as photosynthesis.

4. Carbon enters water to the soil decomposition. Aquatic plants have plenty of water to work with, so their main challenge is getting enough sunlight and air.

6. By breathing in the oxygen from plants.

7. Two ways carbon return from animals into water is through cellular respiration and decomposition.

8. Combustion is when we dig up the fossil fuel and burn it, then what is left goes into the air starting the cycle again.

9. Deforestation reduces the capacity of forests to be carbon sinks.


Nitrogen Cycle:

1. Nitrogen is important because it helps us grow crops, and it produces grass for animal.

2. It comes from lightning and is named nitrogen fixation.

3. Ammonification and then transitions into nitrification and then to assimilation.


Phosphorus Cycle:

1. It forms part of life sustaining molecules like DNA and RNA.

2. Phosphorus is never found in the atmosphere.

The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in wa
olga55 [171]

Answer:

Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.

Explanation:

Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.

Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer

GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.

Leno4ka [110]

Answer:

No it is not a scientific theory.

Explanation:

An explanation of any aspect of the natural phenomenon of the world that can be tested several times and well supported by the evidence, and follows the scientific method. Furthermore known as scientific theory.

Presently, a logical hypothesis must meet a few rules, and one of those is that it must be upheld by a few (and free) strands of proof.  

For this situation, we have just one hypothesis, that bulldogs are great pet and Meatball is great among bulldogs, and it isn't sufficient, at that point it can not be a scientific theory.
