Using the speed of light, calculate for the frequency of an electromagnetic wave with a wavelength of 835 nm.
Answers
The frequency of an electromagnetic wave with a wavelength of 835 nm is 3.6 x 10^14 Hz.
The speed of light is approximately 3 x 10^8 meters per second. To calculate the frequency of an electromagnetic wave, we use the equation.
frequency (Hz) = speed of light (m/s) / wavelength (m)
So, to calculate the frequency of an electromagnetic wave with a wavelength of 835 nm:
frequency (Hz) = 3 x 10^8 m/s / (835 x 10^-9 m)
frequency (Hz) = 3 x 10^8 m/s / 8.35 x 10^-7 m
frequency (Hz) = 3.6 x 10^14 Hz

draw the expanded structural formula for the product is two propanol molecules underwent a dehydration synthesis reaction
Answers
Dehydration of propanol involves the removal of a water molecule from the propanol molecule, resulting in the formation of propene.
What is dehydration of propanol?The reaction is typically carried out by heating propanol with a strong acid catalyst such as sulfuric acid. The reaction can be represented by the following equation:
CH3CH2CH2OH → CH3CH=CH2 + H2O
The reaction proceeds through the formation of a protonated alcohol intermediate, which loses a water molecule to form a carbocation. The carbocation then undergoes deprotonation to form the propene product. The dehydration of propanol is an example of an elimination reaction, where a small molecule is eliminated from a larger molecule to form a new product.

Varicella Zoster is an infectious viral disease causing chickenpox in children and shingles in grown-ups. Inoculation plays a crucial part in avoidance and lessening complications.
Aspeech on Varicella-ZosterWomen and noblemen,
Nowadays, I would like to examine a vital and predominant viral disease known as Varicella Zoster. Varicella Zoster, commonly alluded to as chickenpox, is caused by a varicella-zoster infection. It fundamentally influences children, but can too affect grown-ups who have not been already contaminated.
Varicella Zoster presents as a profoundly infectious sickness characterized by a particular hasty, fever, and common disquietude. The infection spreads through coordinated contact or respiratory beads, making it effortlessly transmissible inside families and communities.
Whereas chickenpox is for the most part a gentle ailment in children, it can lead to more serious complications in grown-ups, pregnant ladies, and people with debilitated resistant frameworks. These complications incorporate pneumonia, bacterial contaminations, and in uncommon cases, neurological complications such as encephalitis.
Luckily, the improvement of a profoundly successful antibody has essentially diminished the frequency of Varicella Zoster around the world. Immunization not as it were secures people from the distress and potential complications of chickenpox, but too makes a difference anticipate the infection from spreading inside the community.
In any case, Varicella Zoster doesn't halt at chickenpox. Once the introductory contamination settles, the infection remains torpid inside the body and can reactivate a long time afterward, causing a condition known as herpes zoster, or more commonly, shingles.
Shingles are characterized by a difficult hasty that ordinarily happens in a single dermatome, regularly along the middle or confront. The reactivated infection can cause critical pain and inconvenience, enduring for weeks or indeed months. Moreover, complications such as postherpetic neuralgia, a persistent torment disorder, can happen, especially in more seasoned people.
To combat the chance of shingles, an isolated antibody called the shingles antibody or herpes zoster immunization has been created. This antibody not as it were makes a difference anticipate shingles but moreover diminishes the chance of postherpetic neuralgia.
In conclusion, Varicella Zoster, enveloping both chickenpox and shingles, could be a viral contamination that has critical suggestions for open well-being. We have made significant progress in reducing the burden of this disease through extensive vaccination efforts.
In any case, ongoing efforts to prevent Varicella zoster from returning to our communities and to protect powerless populations require prompt attention and vaccination.
Much obliged to you for your thought. Let's collaborate to ensure a better future for everyone.

Describe how leaves of green plants are suited for photosynthesis.
Answers
This is a very interesting question, even somewhat mind boggling.
You’ve heard of mitochondria, right? Organelles in embedded in the cells of macro-organisms, such as ourselves, and that carry their own trimmed down genetic code in DNA? Well their is another organelle in cells that has DNA separate from that of the macro-organism. That is the chloroplast, which is what constitutes the green coloration in plant tissue and is where photosynthesis is done in the plant. Chloroplasts have DNA also.
Now, how is that you may well ask. Why would mitochondria and chloroplasts have their own DNA separate from that of the organism that otherwise completely surrounds and sustains them?
Scientists are pretty convinced by now that it is because both mitochondria and chloroplasts used to be free living organisms on their own. At some point in the early history of life, they became symbiotic and then dependent on unicellular host organisms. The dependence, however, was reciprocated, as neither humans nor plants (with significant exceptions) can live without chloroplasts.
So the main adaptation of plants to do photosynthesis has been to incorporate chloroplasts into their own cells and then further adapt their inputs of water and nutrients to take advantage of that.

A new mutation arises in one person on the island of Kiribati (human population size 100,000). Assuming this particular mutation is total neutral, and assuming no gene flow, what is the probability that this mutation will eventually be lost due to genetic drift
Answers
Answer:
0.999999 ≈ 1
Explanation:
In a population ( N ) there is the presence of 2N alleles in the population also chance of fixation can be expressed as ; 1/ 2N
Therefore the probability that the mutation will be lost due to genetic drift
= 2N - 1 / 2N ---- ( 1 )
given that ; N = 100,000
back to equation 1
P ( losing mutation due to genetic drift ) = ((2*100,000) - 1 )) / ( 2* 100,000 )
= ( 200,000 - 1 ) / 200,000

What accounts for the difference in the functions and properties of molecules like starches, glycogen, cellulose, and chitin?
Answers
Answer:
The difference in function and properties of polysaccharides such as starch, glycogen, celluose and chitin is due to the differences in their recurring monosaccharide units, the types of bonds linking these units and the degree of branching in the molecules.
Explanation:
Polysaccharides are large molecules of carbohydrates which are made up of recurring monosaccharide units. Examples of polysaccharides are starch, cellulose, glycogen and chitin. Each of these polysacccharides show differences in structure, properties and function. The difference in function and properties of polysaccharides such as starch, glycogen, celluose and chitin is due to the differences in their recurring monosaccharide units, the types of bonds linking these units and the degree of branching in the molecules.
Starch is the storage carbohydrate in plants and is composed of two types of glucose polymers, amylose and amylopectin. Amylose is composed of unbranched chains of D-glucose units linked to each other by (α1→4) glycosidic bonds. Amylopectin is a branched glucose polymer linked to each other by (α1→4) glycosidic bonds and (α1→6) at the branching points.
Glycogen is the storage polysaccharide in animals which is highly branched and compact. It is composed of (α1→4) linked glucose subunits with (α1→6) at the branching points.
Cellulose is a fibrous, tough and water-insoluble substance found in plant cellwalls. It is is a linear unbranched polysaccharide made up of D-glucose units linked together by (β1→4) glycosidic bonds.
Chitin is is the main component of the exoskeletons of athropods. It is a linear molecule composed of N-acetylglucosamine units linked together by (β1→4) glycosidic bonds.
