Cellulose is a polysaccharide and therefore a polymer, constructed from many monosaccharide glucose monomers.

Cellulose is a polymer that is made up of many glucose monomers. These glucose subunits are joined together by 1-4, glycosidic bonds.

Cellulose may be defined as a type of complex carbohydrate that is one of the chief parts of the cell walls of plants. It is commonly obtained as a white stringy substance from vegetable matter (such as wood or cotton) which is used in making various products.

The glucose units in cellulose are significantly linked together by β glycosidic bonds. This bond pattern is different from the α glycosidic bonds found in glycogen and starch. Cellulose has more hydrogen bonds between adjacent glucose units, both within a chain and between adjacent chains, making it a tougher fiber than glycogen or starch.

Therefore, cellulose is a polymer that is made up of many glucose monomers. These glucose subunits are joined together by 1-4, glycosidic bonds.

Dr. Natterson-Horowitz is a cardiologist at UCLA and a contractor who helped the Los Angeles Zoo, she realized that the divide between treatment of humans and animals in contemporary society.She explains that one of the reasons for this divide is that medical doctors and veterinarians have traditionally been trained in separate disciplines, with little overlap or communication between the two.

One of the three conditions Dr. Natterson-Horowitz mentions that have been well-studied by veterinarians, is cancer, veterinarians have been studying cancer in animals for decades and have developed treatments and therapies that are now being applied to human patients.

Dr. Natterson-Horowitz's argument is that physicians can learn a lot from veterinarians. One of the strongest points in her argument is that veterinarians have been studying diseases and conditions for decades in animals, and their findings can be applied to human medicine.

One argument against the claim that medical doctors and veterinarians do not need to collaborate is that the anatomy and physiology of animals are different from that of humans, and what works for animals may not work for humans. Another argument is that medical doctors and veterinarians have different priorities and goals, with medical doctors focusing on human health and veterinarians focusing on animal health.

Therefore, Another way that these two fields could collaborate is by creating a program that allows medical students to spend time in the field with veterinarians, and vice versa, to gain a better understanding of each other's work and the similarities and differences between human and animal medicine.

Photosynthesis and cellular respiration are connected in a process called the carbon cycle. Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose, which is a type of sugar. Cellular respiration is the process by which plants and animals break down this glucose to release energy. This energy is then used to power various metabolic processes.

Plants and animals mutually benefit each other through these processes. Plants use photosynthesis to produce glucose, which is then absorbed by animals as food. At the same time, animals release carbon dioxide, which is then used by the plants as a source of carbon. This carbon is then incorporated into more glucose, completing the cycle. Thus, both plants and animals benefit from the process of photosynthesis and cellular respiration.

A form of fracture known as a "Greenstick Fracture" occurs when the bone is bent but not completely fractured.

This partial fracture mainly affects young children. The bone flexes and fractures but does not shatter into two distinct pieces. Due to their more flexible and softer bones, children are more susceptible to sustain this kind of fracture. A greenstick fracture happens when a bone fractures and bends rather than totally fracturing into fragments. The fracture resembles what would occur if you were to break a tiny, "green" branch off of a tree. This can happen when a force is applied perpendicular to the bone, such as after a fall on an extended arm, or after an angular longitudinal force is applied down the bone.

The maximum kinetic energy of the photoelectron K0 when light with a wavelength of 310 nm falls on the same surface is 2.135 eV.

You need to find a working function to solve this problem. Quantum Theory Regarding the Photoelectric Effect of the work function (eV), the work function describes the minimum energy required for electrons to continue to stick to the metal.

Planck's constant is also 4.14 x 10⁻¹⁵ eV.

Max KE = 1.10 eV

lambda = 400 nm = 400 x 10⁻⁹ m

First, find the frequency.

f = c ÷ λ

f = (3 x 10⁸) ÷ (400 x 10⁻⁹ m)

f = 7.5 x 10¹⁴

Max KE = hf - work function

1.10 eV = (4.14 x 10⁻¹⁵eV) (7.5 x 10¹⁴) - function

work function = 2.005 eV

Now find the frequency for the second wavelength.

f = c /λ

f = (3 x 10⁸) ÷ (300 x 10⁻⁹)

f = 1 x 10¹⁵

Now plug this into your equation with the frequency and work function you found in the previous problem.

KEmax = hf - work function

KEmax = (4.14 x 10⁻¹⁵ eV)(1 x 10¹⁵) - 2.005 eV

KEmax = 2.135 eV

So, the maximum kinetic energy is 2.005 eV
