How will distinguish between natural and artificial fibres by observing the smell produced when burnt?​

its not biology it's chemistry

Answers

Answer 1

Answer:

Natural fiber smell like paper whereas artificial fiber smells like an acid.

Explanation:

We can distinguish between natural and artificial fibers by observing the smell produced when burnt because both produces different types of smell when burnt. When the artificial fibers are burn, it produces acid or chemical like odor and leaving a plastic like bead while on the other hand, when the natural fiber burn, it produces smell of burning paper or hair and leaving ash of soft and grey colour. Natural organic fibers burn rapidly with a yellow flame.

Which subatomic particle is positively charged?
A. Neutron

Answers

Answer:

Proton

Explanation:

Neutron are neutral, ion I am not sure but are not positive, and electron are -.

Answer: Proton

Explanation:

In an atom there exist three types of sub atomic particles

1) Electrons

2) Neutrons

3) Protons

so we know that electrons are negatively charged particles which stays in a finite orbit as per their energy level

Protons are positively charged particles which remains inside the nucleus and they are tightly bound inside it

Neutrons are neutral sub atomic particles which do not have any charge in it.

So we have correct answer as

Answers

Answer:

'M' for dominant whereas 'm' for recessive allele.

Explanation:

Allele used for myopic man is 'M' whereas the allele used for normal vision is 'm'. The 'M' represents that the allele is dominant and the 'm' refers to the recessive allele. When the dominant allele combine with recessive allele, the organisms have physical features from the dominant organisms while on the other hand, the recessive allele hide and do not appear in the physical appearance of that organisms.

What are three ways that plants impact the cycle ?

Answers

Answer:

Carbondioxide gas, release oxygen and provide food.

Explanation:

Plant absorb carbondioxide gas, release oxygen and provide food to the animals are the was that plants impact the cycle. Plant absorb carbondioxide gas from the surrounding air in the presence of sunlight and absorb water from the soil. Both carbondioxide and water react with each other in leaves producing glucose and oxygen. Glucose is stored in different parts of plant body whereas some oxygen is used by the plant for respiration and the remaining is released in the atmosphere. The food produced in the plant can be eaten by the primary consumer for their growth and in that way the ecosystem moves in forward direction.

Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, and waves of each travel at the same speed. Human eyes are unable to see UV light because it is not in the visible range of the electromagnetic spectrum. If the frequency of one UV light wave is twice that of a visible light wave, how will their wavelengths compare? A. The wavelength of the UV light wave will be half that of the visible light wave. B. The wavelength of the UV light wave will be twice that of the visible light wave. C. The wavelength of the UV light wave will be four times that of the visible light wave. D. The wavelength of the UV light wave will be the same as that of the visible light wave.

Answers

If the frequency of one UV light wave is twice that of a visible light wave, then the wavelength of the UV light wave will be half that of the visible light wave (Option A)

UV is a type of electromagnetic radiation that shows a range of wavelengths from 10 nanometers (nm) to 400 nm, whereas visible light shows a range of wavelengths from 400 to 700 nm (0.4 to 0.7 µm).

UV light exhibits a higher frequency and shorter wavelength than visible light.

The frequency is a unit measured in Hertz (Hz) which indicates the number of cycles (i.e., the waves) that pass a point in space during one sec.

The longest wavelength of visible light is the red color (700nm), whereas and the shortest visible wavelength is blue (400nm).

The frequency of the visible light ranges from 7.5×10¹⁴ Hz (blue color) to 4.3×10¹⁴ Hz (red color); whereas the frequency of UV light ranges from 800 terahertz (THz) to 30,000 THz.

Answers

The dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.

Why the colour of the solution change?

The color of the solution turns from yellow to blue color due to the release bromothymol blue because plant can't absorb bromothymol blue so it dissolved in the solution which leads to the change of colour of the solution from  yellow to blue.

So we can conclude that the dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.

Explanation:

DNA is a double-stranded molecule i.e. it consists of two strands that are complementary to one another. According to the complementary base pairing rule, adenine base (A) will always hydrogen pair with Thymine base (T) i.e. A-T while Guanine base (G) will always hydrogen pair with Cytosine base (C) i.e. C-G.

Hence, based on the above explanation of complementary base pairing, the complementary pair of each DNA strand in this question are as follows;

Nosotrosmsica rock. (escuchar)What do I fill the blank with HELP PLEASEMetamorphosisby Frank KafkaOne morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible vermin. He lay on his armor-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked.Whats happened to me? he thought. It wasnt a dream.Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the pane, which made him feel quite sad. How about if I sleep a little bit longer and forget all this nonsense, he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldnt get into that position. However hard he threw himself onto his right, he always rolled back to where he was. He must have tried it a hundred times, shut his eyes so that he wouldnt have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before.There was a cautious knock at the door near his head. Gregor, somebody calledit was his motherits quarter to seven. Didnt you want to go somewhere? Gregor was shocked when he heard his own voice answering, it could hardly be recognized as the voice he had had before. As if from deep inside him, there was a painful and uncontrollable squeaking mixed in with it, the words could be made out at first but then there was a sort of echo which made them unclear. Gregor had wanted to give a full answer and explain everything, but in the circumstances contented himself with saying: Yes, mother, yes, thank-you, Im getting up now.Review the excerpt from the story Metamorphosis and answer the question below:Gregor wakes up to find himself transformed. Do you think this was a dream or not? In two to three sentences, explain your answer. Use evidence from the text to support your answer.
