Answer: The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties.
Explanation:
Starch and Cellulose flare both polysaccharides which are constructed from the same monomer called glucose. The functions they provide in plants are different which includes the following:
- STARCH is used by plants for energy storage because unlike Cellulose, it's formed from glucose units( oriented in the same direction) connected by alpha linkages which can form compact structures that can easily be broken down.
- Cellulose provides structural support for plant cell wall because unlike Starch, it's formed from glucose units( which rotates 180 degrees around the axis of the polymer backbone chain) connected by beta linkages. This pattern gives Cellulose it's rigid features as is allows for hydrogen bonding between two molecules of Cellulose.
Therefore the statement that best describes why starch and cellulose provide different functions in plants is that (The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties).
Answer:
they are called Mechanical waves and there are two kinds Transverse waves and compressional waves. Where matter in the medium moves back and forth at right angles to the direction the wave travels. I hope dis helps :3
It will be half
A normal cell contains 46 chromosomes.
Gametes only contain 23 because they will be paired with an opposite gamete cell upon fertilisation
- Egg contains 23
- Sperm contains 23
Together they make the normal amount of 46
Answer:
1) A chemical reaction is shown.
SnO2 + H2 → Sn + H2O
What is true about this chemical reaction?
B.
It is unbalanced because the mass of the reactants (number of atoms) is greater than the mass of the products (number of atoms).
2) Read the information about an experiment.
Jadon plans on carrying out an experiment involving the burning of steel wool to illustrate the conservation of mass. Steel wool is made of iron. When it is burned it combines with oxygen to form iron(III) oxide.
Which step in his experiment is the most important if he wants his experiment to correctly demonstrate the conservation of mass?
A.
The steel wool should be burned inside of a sealed jar or other closed system.

The average red blood cell lives for 120 days.
2. There are 2.5 trillion (give or take) of red blood cells in your body at any moment. To maintain this number, about two and a half million new ones need to be produced every second by your bone marrow.That's like a new population of the city of Toronto every second.
3. Considering all the tissues and cells in your body, 25 million new cells are being produced each second.That's a little less than the population of Canada - every second !
4. A red blood cell can circumnavigate your body in under 20 seconds.
5. Nerve Impulses travel at over 400 km/hr (25 mi/hr).
6. A sneeze generates a wind of 166 km/hr (100 mi/hr), and a cough moves out at 100 km/hr(60 mi/hr).
7. Our heart beats around 100,00 times every day.
8. Our blood is on a 60,000-mile journey.
